Individuals recovering from stroke often experience impaired proprioception, which limits motor control and slows rehabilitation. Existing solutions are often expensive or unsuitable for home use.

Design and evaluate an affordable, wearable system capable of delivering proprioceptive feedback and quantitatively assessing its impact on motor performance.

Co-designed a wristband with dual muscle–tendon vibration controlled via Raspberry Pi. Developed control code, designed a 3D-printed interface, and conducted human-subject testing to analyze motor metrics.

Demonstrated improved motor consistency and accuracy during vibration conditions. Results support translation to scalable, home-based rehabilitation devices.

Traditional transtibial prosthetic socket manufacturing is labor-intensive and time-consuming, limiting clinic scalability and increasing production costs.

Develop a more efficient manufacturing workflow that maintains clinical quality and patient satisfaction while reducing production time and labor.

Led feasibility testing of a hybrid workflow combining manual casting with 3D scanning, digital design, and additive manufacturing. Conducted physical property testing and quantified labor metrics.

Reduced hands-on labor by 22.1% and total production time by 26.4% while maintaining quality. Demonstrated a cost-effective approach to modern fabrication.

Early detection of wound infections is critical, but existing indicators often produce false positives due to environmental factors like pH and salt concentration.

Improve the reliability and specificity of colorimetric wound infection sensors by reducing false positives while maintaining sensitivity to bacterial activity.

Modified electrospun polyurethane formulations to reduce interference. Fabricated nanofibrous membranes and tested response against bacterial cultures and commercial lipases.

Eliminated false positives and detected bacterial concentrations from 10¹⁰ to 10¹³ CFU/cm². Membranes also inhibited localized bacterial growth.

Adaptive bicycles used in pediatric rehabilitation lack objective metrics to quantify cycling biomechanics and track rehabilitation progress.

Assess the feasibility of integrating sensing and motion capture technologies into adaptive tricycles to enable quantitative rehabilitation assessment.

Evaluated markerless motion capture platforms (Move.ai) and designed a preliminary pressure-sensing system for the seat and backrest to assess posture and weight distribution.

Proved feasibility of transforming adaptive bicycles into smart tools providing objective feedback for personalized therapy and progress tracking.

Approximately 25% of power wheelchair-related injuries involve the lower extremities, often caused by collisions with environmental obstacles.

Design a cost-effective, detachable foot guard that protects users' feet without restricting mobility or wheelchair maneuverability.

Collected dimensional data, supported mechanical design under strict constraints, and assisted in prototype fabrication and collision testing.

Final prototype cost $110.53 (1/3 commercial cost), successfully protecting users' feet while preventing damage to surrounding surfaces.

El Jicaro faces severe water scarcity, especially in summer. Residents must walk long distances to access water, then filter it for safe consumption. Those without transportation pay high costs from distant cities, making water access a critical health challenge.

Design a water distribution system that addresses scarcity, reduces transportation burden, and provides safe, accessible water to all households while remaining financially feasible.

Collaborated with Global Brigades staff and community to survey water infrastructure and collect GPS data. Designed an optimized water system in EPANET with two tanks and pressure breaker valve. Created a scalable design for future expansion and mapped 14.21 km of pipeline infrastructure with detailed construction budget.

Designed a complete water system with two tanks, pressure breaker, and 14.21 km pipeline. Total cost: $146,700 CAD (consultation $15,700, materials $53,000, well $26,000, meters $5,000, labor $57,000). Community contribution: $89,000. Provides reliable water access with ongoing support from Global Brigades and the design team.
