I'm a Biomedical Engineering student at the University of Waterloo, happiest when I'm building something: machine learning pipelines for healthcare, prosthetic hands, experiment games, the occasional 3D-printed beaver. Away from the keyboard I play squash (the sport, though I'm fond of the vegetable too), respond with the campus first-aid team, and say yes to more community projects than strictly fit in a calendar.

Currently working on healthcare AI at Signal1 and making the most of Toronto summer runs.

Signal1

Machine Learning Intern

Jun. 2026 – Present Toronto, ON
Signal1
Machine Learning Python Healthcare AI

I help make healthcare AI agents safe, measurable, and deployment-ready.

At Signal 1, I build evaluation and experimentation infrastructure for agentic AI systems, including clinically grounded benchmarks, execution-trace analysis, regression testing, and auditable validation workflows for multi-step healthcare tasks.

The Hospital for Sick Children (SickKids)

Bioinformatics Software Research Student

Sep. 2025 – Dec. 2025 Toronto, ON
Machine Learning Python Bioinformatics

As a Bioinformatics Software Research Student at The Hospital for Sick Children (SickKids), I worked at the intersection of machine learning and genomic medicine to support clinical research. I designed and implemented an end-to-end ML pipeline to predict cognitive, language, and motor outcomes in preterm infants using demographic, clinical, and MRI data.

I also contributed to the design and iteration of a protein language model variant effect predictor, analyzing attention mechanisms to improve model interpretability. I collaborated with clinicians and researchers to drive impact in pediatric precision medicine.

Transport Canada

Data Science and Process Mining Analyst

Oct. 2024 – Mar. 2025 Ottawa, ON
Python Data Analysis Process Mining

As a Data Science and Process Mining Analyst at Transport Canada, I led two major process mining projects to enhance the efficiency of federal workflows. Using Python-based analytics, I identified bottlenecks in large-scale operational logs and delivered data-driven recommendations to policy and operations teams.

I built a secure and cost-efficient machine learning pipeline to automate classification tasks and reduce administrative burden, while also developing process conformance models and interactive dashboards that enabled stakeholders to act on insights with confidence.

Carleton University

Cognitive Engineering Research Assistant

2024 Ottawa, ON
EEG Analysis MATLAB UX/UI Design

As a Cognitive Engineering Research Intern at the ACE Lab, I focused on improving human interaction with complex systems through cognitive science and usability research. A core part of my work was contributing to the interdisciplinary SENSE-APP project, developed in collaboration with Carleton researchers and the National Research Council (NRC). The project aimed to assess driving risk in older adults using AI and telematics data, then communicate insights back to users to promote safer, longer driving.

I analyzed qualitative focus group data with QDA Miner, identifying key themes that directly shaped UX/UI design decisions. In parallel, I supported studies on human–machine interaction in autonomous driving, building experimental environments in Prepar3D and coding auditory stimuli for EEG data collection. I also designed a situational awareness task in Godot to evaluate hazard perception in ongoing research.

Town of Mahone Bay

Manager

2022 – 2023 Mahone Bay, NS
Team Management Leadership Operations

As a Manager and Assistant Manager from 2022 to 2023, I was responsible for overseeing the daily operations and safety of over 100 patrons, while leading a team of seven aquatic staff. I managed scheduling, training, and financial coordination to ensure the smooth delivery of high-quality community programs.

In addition to leadership responsibilities, I served as a lifeguard, swim instructor, and lifesaving course instructor, managing and delivering aquatic programming for all ages. Recently, I joined the Board of Directors, where I contribute to reopening strategy and the planning of a new facility to support long-term community growth. Learn more on our website.

University of Waterloo Health Services

Responder, UW Campus Response Team

2023 – Present Waterloo, ON
First Aid Crisis Management Training

As a Responder with the University of Waterloo Campus Response Team (2023–Present), I support the safety and well-being of the university community by responding to medical and mental health emergencies during shifts and on-call coverage.

In Winter 2024, I served as an Assistant Trainer, running assessment sessions and helping organize training in first aid and crisis management. Through this role, I contributed to strengthening the team's readiness and overall emergency response capabilities.

Projects things I've built (and broken, and rebuilt)

Spatial snapshots of an SA wave propagating through fibrotic tissue

Modeling SA Waves in Fibrotic Tissue

Talk accepted 2026
Artificial Life Computational Modeling Cardiac Electrophysiology

Authored a paper investigating how sinoatrial action-potential waves propagate through fibrotic tissue. The work uses spatial simulations to compare wave behaviour over time and make the effect of different fibrosis structures visible.

Field Course in Ghana

Field Course in Ghana

2026
Field Research Public Health Interculturalism

Field course in Ghana studying water, sanitation, and health through field visits, community conversations, and site-based learning.

I saw how WASH systems are shaped by much more than infrastructure: governance, gender, financing, culture, and everyday use all determine whether a system actually works.

For my knowledge mobilization project, I built an interactive map game where players follow the course route, collect field-journal tokens, and gradually build a systems diagram from what we learned on the ground. Play it here.
