One example of a capstone project in computer science would be developing a customized medical information system for a clinic or hospital. For a project of this scope and scale, students would work in a team to analyze requirements, design the system architecture, develop the necessary code and applications, implement security features, test all aspects of the system, and deploy it for real-world use at the medical facility.

In the initial phases, the student team would work closely with administrators, doctors, nurses and other medical staff at the facility to understand their detailed workflow processes, data storage and reporting needs, and systems integration requirements. This requirements gathering and analysis phase is crucial to understand all of the features and functionality that must be included in the custom medical information system. The team would document gathered requirements, perform gap analysis on current workflows versus desired future state, and prioritize features to ensure the system addresses top priorities and pain points.

With a comprehensive understanding of requirements in hand, the student team would then begin designing the system architecture. Key consideration would include decisions around database structure and schemas, backend application design using appropriate programming languages and frameworks, front-end user interface designs for various user roles (doctors, nurses, administrators etc.), integration with existing practice management systems or electronic health records if needed. Important non-functional requirements around security, privacy, performance, scalability and maintainability would also influence architectural design decisions.

Detailed documentation of the system architecture design would be created, covering database models, application component diagrams, interface wireframes, infrastructure requirements and more. Students would present and defend their proposed architecture to stakeholders to obtain feedback and approval before moving to implementation.

The implementation phase represents the bulk of effort for the project where students translate designs into working code and applications. Key activities would include:

Building out the backend applications using languages like PHP, Python, Java or .NET to implement the required functionality based on requirements and architectural designs. This includes developing APIs, business logic and integration layers.

Creating a frontend UI using HTML, CSS and JavaScript frameworks like React or Angular that adheres to user experience designs and provides role-based interfaces.

Setting up and configuring a database like MySQL, SQL Server or MongoDB based on the data models and architecting appropriate schemas, indexes, foreign keys etc.

Populating the database with sample test data including demo patient records, appointment schedules, insurance profiles and more to enable thorough testing later.

Integrating the custom system with other existing medical facility systems like practice management software or EHR products through pre-defined APIs.

Implementing security features like multi-factor authentication, authorization controls, encrypted data transfer and storage, input validation etc. based on a thorough security risk assessment.

Developing comprehensive installation, configuration and operation guides for medical staff.

Performing extensive testing of all functionality from different user perspectives to uncover bugs. This includes unit testing code, integration testing, user acceptance testing, load/stress testing and more.

Once development is complete, the student team would help deploy and launch the new medical information system at the partner medical facility. This includes performing the necessary installation and configuration activities, onboarding and training of medical staff, addressing any post-deployment issues, and measuring success based on defined key performance indicators.

Ongoing maintenance and improvements to the system over several months post deployment may also be part of the project scope, requiring the team to monitor system performance, implement requested enhancements, and resolve production issues.

In the concluding project phases, the student team would document the complete system development lifecycle and create a comprehensive final report. An oral presentation would be given to stakeholders highlighting achievements, lessons learned, future roadmap for the system and reflections on career readiness gained through such a hands-on capstone project experience.

An example medical information system capstone project as outlined above covers the full scope from requirements analysis to deployment, addresses real-world problems through technical solutions, and provides students an in-depth industry-aligned experience to showcase their cumulative skills and knowledge gained throughout their computer science education. Completing a complex project of this scale truly allows students to synthesize their learning and strengthens their career preparedness for jobs in both software development and healthcare IT fields.


Customer churn prediction model (17,274 characters):

One common capstone project is building a predictive model to identify customers who are likely to churn, or stop doing business with a company. For this project, you would work with a large dataset of customer transactions, demographics, service records, surveys, etc. from a company. Your goal would be to analyze this data to develop a machine learning model that can accurately predict which existing customers are most at risk of churning in the next 6-12 months.

Some key steps would include: exploring and cleaning the data, performing EDA to understand customer profiles and behaviors of churners vs non-churners, engineering relevant features, selecting and training various classification algorithms (logistic regression, decision trees, random forest, neural networks etc.), performing model validation and hyperparameter tuning, selecting the best model based on metrics like AUC, accuracy etc. You would then discuss optimizations like targeting customers identified as high risk with customized retention offers. Additional analysis could involve determining common reasons for churn by examining comments in surveys. A polished report would document the full end to end process, conclusions and business recommendations.

Drug discovery and molecular modeling (14,976 characters)

With advances in biotech, data science is playing a key role in accelerating drug discovery processes. For this capstone, publicly available gene expression datasets as well as molecular structure datasets could be analyzed to aid target discovery and virtual screening of potential drug candidates. Unsupervised methods like principal component analysis and hierarchical clustering may help identify novel targets and biomarkers.

Techniques in natural language processing could be applied to biomedical literature to extract relationships between genes/proteins and diseases. Cheminformatics approaches involving property prediction, molecular fingerprinting and substructure searching could aid in virtual screening of candidate molecules from database collections. Molecular docking simulations may further refine candidates by predicting binding affinity to protein targets of interest. Lead optimization may involve generating structural analogs of prioritized molecules and predicting properties like ADMET (absorption, distribution, metabolism, excretion, toxicity) profiles.

The final report would summarize key findings and ranked drug candidates along with discussion on limitations of computational methods and need for further experimental validation. Visualizations of molecular structures and interactions may help communicate insights. The project aims to demonstrate how multi-omic datasets and modern machine learning/AI are revolutionizing various stages of drug development process.


Website/Web Application Development:
A very common capstone project is developing a full-stack website or web application from scratch. Some examples of web app capstones include:

An online marketplace application where users can list products for sale and other users can browse listings and purchase items. This would involve building a database to store product/user information, developing the front-end site using HTML/CSS/JavaScript, and creating backend functionality with a language like PHP, Python or Java.

A social networking site similar to Facebook where users can create profiles, share posts/photos, connect with friends, send messages. This encompasses building the database schema, designing interactive frontend interfaces, implementing authentication/privacy features.

A web app for organizing and scheduling employee timesheets/time-off requests with management approval workflows. This integrated a calendar system, user roles/privileges, and administrative reporting features.

Game Development:
Creating a playable, fully-functional game is a popular choice that requires skills in computer graphics, simulation, AI and more. Examples include:

A 2D side-scrolling platformer game where the player navigates different levels, collects items, avoids obstacles and enemies. Implementation included sprite graphics, character controls, collision detection, level design.

A 3D first-person puzzle game set in a maze-like environment. Challenges involved 3D modeling/texturing game assets, scripting puzzle/level logic, developing the player character’s navigation abilities.

A multiplayer online battle arena (MOBA) game inspired by titles like Dota 2 or League of Legends. Developing the networked code for simultaneous multiple player gameplay across different devices presented difficulties.

An augmented reality (AR) application/game making use of a mobile device’s camera, GPS sensors to overlay virtual objects/characters onto the real world. Synchronizing the virtual and physical posed programming hurdles.

Data Analytics/Machine Learning:
Applying computing skills to analyze real-world datasets and build predictive models also constitute valuable capstone topics, for instance:

Building a recommendation engine for movies, books, music or products based on collaborative filtering of user preferences/behavior data. Techniques included developing similarity measures and generating personalized recommendations.

Analyzing social media data scraped from public Twitter/Facebook profiles to predict user demographics based on linguistic patterns in posts/bios. Natural language processing, data wrangling and machine learning models were essential.

Using satellite/weather station records to train a convolutional neural network that detects hurricanes/storms in satellite imagery with a high degree of accuracy. Gathering/preparing the image dataset along with deep learning implementation proved challenging.

Applying computer vision techniques to diagnose cancers/diseases by classifying cell images with transfer learning on pre-existing models. Evaluating accuracy on new medical imaging test cases required domain expertise.

A photo management/sharing app allowing users to apply filters, edit photos and post to social networks directly from their camera rolls. Optimizing image processing performance across various hardware was problematic.

Effective capstone projects require extensive independent work to research, plan and implement sophisticated computing ideas from start to finish. While topics will vary between individuals/programs, web, mobile and game development, data analysis and machine learning represent common areas that allow students to demonstrate multiple acquired technical abilities through substantial applied programming challenges. The projects often yield tools and experiences directly applicable for future career paths or startup ideas. With a well-considered scope, ample collaboration and iterative problem-solving, these final year efforts can result in highly impressive demonstrations of technical competency for any computer science graduate.


Developing an Intelligent Tutoring System for Computer Science using Artificial Intelligence and Machine Learning

For my capstone project, I designed and developed an intelligent tutoring system (ITS) to help students learn core concepts in computer science. An ITS is an advanced form of computer-based learning that uses artificial intelligence (AI) techniques to provide personalized instruction, feedback and guidance to students. My ITS focused on teaching topics in algorithms, data structures, programming languages and software engineering.

In designing the system, I drew upon knowledge from several key areas of computer science including AI, machine learning, human-computer interaction, databases and web development. The core of the ITS utilized AI and machine learning techniques to model a student’s knowledge, identify learning gaps and deficiencies, adapt instruction to their needs and provide individualized remedial help. It incorporated a dedicated student model that was continuously updated based on a student’s interactions with the tutoring system.

On the front-end, I designed and developed a responsive web interface for the ITS using HTML, CSS and JavaScript to provide an engaging and intuitive learning experience for students. The interface allowed students to access learning modules, take practice quizzes and exams, view step-by-step video tutorials and receive personalized feedback on their progress. It was optimized for use on both desktop and mobile devices.

For content delivery, I structured the learning materials and created interactive modules, activities and assessments covering fundamental CS topics like problem solving, algorithm design, data abstraction, programming paradigms, software engineering principles and more. The modules utilized a variety of multimedia like text, diagrams, animations and videos to explain concepts in an easy to understand manner. Students could self-pace through the modules based on their skill level and interests.

To power the back-end intelligence, I employed advanced machine learning algorithms and applied Artificial Neural Network models. A multi-layer perceptron neural network was trained on a large dataset of student-system interactions to analyze patterns and correlations between a student’s knowledge state, mistakes, provided feedback and subsequent performance. This enabled the ITS to precisely identify a student’s strengths and weaknesses to develop personalized study plans, recommend relevant learning resources and target problem areas through adaptive remedial work.

Assessments in the form of quizzes and exams were designed to evaluate a student’s conceptual understanding and practical problem-solving abilities. These were automatically graded by the system using test cases and model solutions. Detailed diagnostic feedback analyzed the exact mistakes and misconceptions to effectively guide students. The student model was also updated based on assessment outcomes through machine learning techniques like Bayesian knowledge tracing.

To power the backend data processing and provide an API for the AI/ML components, I built a database using PostgreSQL and implemented a RESTful web service using Node.js and Express.js. This facilitated real-time data exchange between the frontend interface and various backend services for student modeling, content delivery, assessment grading and feedback generation. It also supported additional capabilities like student enrollment/registration, content authoring and administrative functions.

Extensive user testing and validation was performed with a focus group of undergraduate CS students to fine-tune design aspects, evaluate learning outcomes, identify bugs/issues and measure student engagement, satisfaction and perceived learning value. Feedback was incorporated in iterative development cycles to enhance the overall user experience. Once validated, the system was deployed on a cloud hosting platform to enable broader use and data collection at scale. The ITS demonstrated the application of core computer science principles through an integrated project that combined areas like AI, ML, HCI, databases and software engineering. It proved highly effective at delivering personalized adapted learning to students in a facile manner. The system won institutional recognition and has since helped hundreds of learners worldwide gain skills in algorithms and programming.

Through this capstone project I was not only able to apply my theoretical computer science knowledge but also develop practical hands-on expertise across multiple domains. I gained valuable skills in areas such as AI system design, machine learning, full-stack web development, database modelling, project management and user evaluation methodologies. The experience of envisioning, architecting and implementing an end-to-end intelligent tutoring application helped hone my abilities as a well-rounded computer scientist. It also enabled me to effectively utilize techniques from various CS sub-domains in an integrated manner to solve a real-world problem – thus achieving the overarching goals of my capstone experience. This proved to be an immensely rewarding learning experience that has better prepared me for future career opportunities and research pursuits at the intersection of these technologies.


The Human Genome Project was one of the earliest and most important high-performance computing projects that had a massive impact on the field of computer science as well as biology and medicine. The goal of the project was to sequence the entire human genome and identify all the approximately 20,000-25,000 genes in human DNA. This required analyzing the 3 billion base pairs that make up human DNA. Sequence data was generated at multiple laboratories and bioinformatics centers worldwide, which produced enormous amounts of data that needed to be stored, analyzed and compared using supercomputers. It would have been impossible to accomplish this monumental task without the use of high-performance computing systems that could process petabytes of data in parallel. The Human Genome Project spanned over a decade from 1990-2003 and its success demonstrated the power of HPC in solving complex biological problems at an unprecedented scale.

The Distributed Fast Multipole Method (DFMM) is an HPC algorithm that is very widely used for the fast evaluation of potentials in large particle systems. It has applications in the fields of computational physics and engineering for simulations involving electromagnetic, gravitational or fluid interactions between particles. The key idea behind the DFMM algorithm is that it can simulate interactions between particles with good accuracy while greatly reducing the calculation time from O(N^2) to O(N) using a particle clustering and multipole expansion approach. This makes it perfect for very large particle systems that can number in the billions. Several HPC projects have focused on implementing efficient parallel versions of the DFMM algorithm and applying it to cutting edge simulations. For example, researchers at ORNL implemented a massively parallel DFMM code that has been used on their supercomputers to simulate astrophysical problems with up to a trillion particles.

Molecular dynamics simulations are another area that has greatly benefited from advances in high-performance computing. They can model atomic interactions in large biomolecular and material systems over nanosecond to microsecond timescales. This provides a way to study complex dynamic processes like protein folding at an atomistic level. Examples of landmark HPC projects involving molecular dynamics include simulating the folding of complete HIV viral capsids and studying the assembly of microtubules with hundreds of millions of atoms on supercomputers. Recent HPC projects by groups like Folding@Home also use distributed computing approaches to crowdsource massive molecular simulations and contribute to research on diseases. The high fidelity models enabled by ever increasing computation power are providing new biological insights that would otherwise not be possible through experimental means alone.

HPC has also transformed various fields within computer science itself through major simulation and modeling initiatives. Notable examples include simulating the behavior of parallel and distributed systems, development of new parallel algorithms, design and optimization of chip architectures, optimizing compilers for supercomputers and studying quantum computing architectures. For instance, major hardware vendors routinely simulate future processors containing billions of transistors before physically fabrication them to save development time and costs. Similarly, studying algorithms for exascale architectures requires first prototyping them on petascale machines through simulation. HPC is thus an enabler for exploring new computational frontiers through in silico experimentation even before the actual implementations are realized.

Some other critical high-performance computing application areas in computer science research that leverage massive computational resources include:

Big data analytics: Projects involving analyzing massive datasets from genomics, web search, social networks etc. on HPC clusters and using techniques like MapReduce. Examples include analyzing NASA’s satellite data or commercial applications by companies like Facebook, Google.

Artificial intelligence: Training very large deep neural networks on datasets containing millions or billions of images/records requires HPC resources with GPUs. Self-driving car simulations, protein structure predictions using deep learning are examples.

Cosmology simulations: Modeling the evolution of the universe and formation of galaxies using computational cosmology on some of the largest supercomputers. Insights into dark matter distribution, properties of the early universe.

Climate modeling: Running global climate models with unprecedented resolution to study changes, make predictions. Projects like CMIP, analyzing petascale climate data.

Cybersecurity: Simulating network traffic, studying botnet behavior, malware analysis, encrypted traffic analysis require high performance systems.

High-performance computing has been instrumental in solving some of the biggest challenges in computer science as well as enabling discovery across a wide breadth of scientific domains by providing massively parallel computational capabilities that were previously unimaginable. It will continue powering innovations in exascale simulations, artificial intelligence, and many emerging areas in the foreseeable future.
