Studying human factors engineering to make technology intuitive.

Studying human factors engineering to make technology intuitive.

I'm an M.Eng. in Human Factors Engineering at Virginia Tech with a foundation in human perception and cognitive psychology with experience in UX evaluation, experimental research, and interaction design. I care about designing systems and interfaces that think of the user first.

Mobile App Usability Evaluation

Self Directed Project · Fall 2026

A usability evaluation conducted on a mobile app's task flows. User tasks were mapped and pain points identified through heuristic evaluation, then translated findings into Figma mockups for redesign. A moderated usability test is planned to validate findings and dig deeper into why the pain points occurred.

Experimental Design Signal Detection Coursework

Traffic Signal Detection Experiment

Human Information Processing · Fall 2026

Designed a controlled experiment to understand how color vision deficiency and glance duration affect a driver's ability to detect traffic signals. I built 80 unique stimuli varying across both dimensions and led the experimental design for a go/brake detection task, showcasing a direct application of signal detection theory to a real-world safety problem.

Nintendo Switch 2 UI Usability Test & Figma Prototype IN PROGRESS

Human Factors System Design · Fall 2026

Leading a 3-person team through a usability test of the Nintendo Switch 2's home screen UI. We define target users, surface human factors deficiencies through task-based usability testing, and build Figma prototypes that address the most critical issues in this consumer product.

Research Assistant · Sep 2026 - Present

Cognitive Engineering for Novel Technologies (COGENT) Lab

Virginia Tech · Blacksburg, VA

Supporting an ongoing study on whether expertise tailored AR overlays change how effectively people perform technical inspection tasks. Hands on with HoloLens 2 calibration, experimental trial setup, and live data collection experience at the intersection of extended reality and human performance.

AR / HoloLens 2 Exp. Design Data Collection
Principal Investigator · Jan 2025 - May 2026

Human Development Lab

James Madison University · Harrisonburg, VA

Designed and ran an IRB-approved study with 200+ participants while serving as Principal Investigator. Deployed three Qualtrics instruments and conducted a full statistical analysis in SPSS examining how sleep and mental health jointly predict cognitive performance. Presented findings at both the 2025 and 2026 JMU Psychology Symposium.
