Bioprinting @ Berkeley - Prosthetic Arm Team
Lead Design Engineer | September 2023 - May 2024
Project team under the club Bioprinting @ Berkeley, where we have been conducting continuing research and rapid prototyping of a functional bionic arm using SolidWorks & other CAD programs.
This technical team is composed of folks from different engineering backgrounds (Bioengineering, EECS, Mechanical Engineering). We are devoted to assembling a prosthetic arm to grab items, have full-finger mobility, and maybe even shake your hand. :)
Produced an electromechanical prosthetic arm in a cross-functional undergraduate team using Onshape.
Validated post-production of 3D-printed parts to resemble a functional moving arm.
Skills Utilized
SolidWorks, Onshape
Cross-functional Collaboration

The presentation slides from our final deliverable "FarmQuest" highlight the progress, functionality, user feedback, and limitations of our deliverable for Castlemont High School.
Fung Fellowship, Conservation + Innovation Track
Final Deliverable "FarmQuest" | Fall 2023
Fung Fellowship, Conservation + Innovation Track
Final Deliverable "FarmQuest" | Fall 2023
The Fung Fellowship at UC Berkeley's Fung Institute for Engineering Leadership centers on human-centered design principles to advance innovative solutions for biodiversity, environmental health, and conservation.
In collaboration with the Fung Fellowship 23-24 community partners: Civic Design Studio and Castlemont High School, our final team deliverable proposed printable educational activities to enhance student engagement and educational activities of biodiversity, conservation practices, and Indigenous land practices within Castlemont High School's farm.
As the hardware design lead, I focused on the 3D design and prototyping of the honeycomb-shaped housing, modeling in SolidWorks, and rapid prototyping with PLA plastic. Additionally, I designed the prototype's circuitry with TinkerCAD and electrical parts.

Engineering World Health's 2023 Virtual Engineering Exchange Program
UC Berkeley & University of Nairobi | June 2023 - July 2023
Engineering World Health's 2023 Virtual Engineering Exchange Program
UC Berkeley & University of Nairobi | June 2023 - July 2023
A 6-week virtual innovation program with a cohort of undergraduate and graduate students from UC Berkeley and the University of Nairobi in Kenya. In this program, we learned about enhancing engineering solutions for low-resource environments through biomedical design, collaboration, ethics, and entrepreneurship.
Our team's final deliverable proposed enhancements to oxygen concentrators in low-resource environments through a durable, portable oxygen concentrator powered by solar energy, and modeling in SolidWorks.
The presentation slides from our final deliverable presentation propose enhancements to the oxygen concentrator for solar power functionality, durability, and portability in low-resource environments.
