Key Projects
Biomechanical Data Analysis Application
Designed a human-centered MATLAB application for analyzing biomechanical datasets from human studies. The tool supports statistical testing, advanced signal preprocessing, and interactive data visualization to enhance the analysis of human motion. Focused on maximizing data quality and usability, enabling safe and personalized insights in health and movement research.
Key Features & Human Factors Relevance:
- Robust Outlier Detection: Implemented methods (Slope, IQR, Z-score, MAD) for data integrity in human studies.
- Advanced Signal Processing: Incorporated filters and smoothing techniques to refine raw physiological data.
- Temporal Normalization & Synchronization: Developed algorithms for precise alignment of time-series data (e.g., gait cycles).
- Integrated Statistical Analysis & Visualization: Enabled direct statistical testing and interactive plotting for actionable insights.
- User Interface (UI) Development: Designed a user-friendly MATLAB GUI for accessible and efficient research tools.
Impact:
Built a flexible analysis tool that streamlined the evaluation of human movement data and supported robust comparisons between walking conditions. The project demonstrated my ability to design clear, user-friendly analysis workflows that deliver actionable insights for research in biomechanics and wearable technologies.
Dark Mode & Website Credibility Study
As a key member of a four-person research team, I co-designed and conducted a rigorous lab study investigating the subtle influences of dark mode and ambient lighting on users' perceptions of website credibility. This project encompassed the entire research lifecycle, from initial conceptualization and experimental design to data collection, comprehensive analysis, and final evaluation, demonstrating my proficiency in both quantitative and qualitative research methodologies crucial for Human Factors Engineering.
Research Process & Human Factors Relevance:
- Conceptualization & Research Question: Explored impact of visual modes on user trust and perception.
- Experimental Design & Protocol: Developed rigorous study protocols for visual design and user perception, including light/dark mode and ambient lighting conditions.
- Data Collection & Methodology: Hands-on experience collecting diverse data (quantitative ratings, qualitative feedback) and applying advanced statistical/qualitative analysis.
- Usability Testing & Interface Evaluation: Focused on evaluating user experience, prioritizing cognitive and perceptual processes.
- Analysis & Scientific Communication: Translated complex findings into clear, influential recommendations for design and engineering teams.
Key Findings:
The study provided valuable insights into how visual design choices impact user trust and credibility. While overall effects of dark mode were not significant, nuanced findings related to gender and technical background emerged. Specifically, males rated website credibility significantly higher than females (p=0.043), and participants with a technical background assessed credibility higher in light mode and bright environments. This highlights my ability to conduct rigorous user research and translate findings into practical UI/UX implications.

Interactive Snakes & Ladders Game
Designed and developed a digital version of the classic Snakes and Ladders board game using MATLAB GUI. The game includes dynamic board rendering, intuitive turn-based logic, and interactive player movement with immediate visual feedback.
This project showcases my ability to create playful, user-centered digital experiences. With a strong focus on clarity, usability, and engagement, it reflects key principles of human-centered design and demonstrates how thoughtful interaction design can enhance enjoyment and accessibility in everyday applications.
Human Factors & UX Highlights:
- User-Centric Interface Design: Crafted an attractive and intuitive MATLAB GUI, optimizing user cognitive load and engagement.
- Personalization & Engagement: Integrated features for player names and piece colors, enhancing personal connection.
- Progressive Challenge Design: Introduced mini-games with varied difficulty, showcasing understanding of user motivation.
- Accessibility & Adaptability: Ensured resizable application compatible across different PCs.
- Problem-Solving & Software Development: Translated complex game logic into a functional and enjoyable interactive application.
