Engineering Background & Why I Build

I am a sophomore studying Mechanical and Biomedical Engineering at Tufts University (Anticipated Graduation: May 2028). I am driven by the challenge of taking complex, open-ended physical problems from first-principles physics and 3D CAD all the way to reliable, manufacturable hardware.

Whether I am optimizing a titanium implant's geometry in SolidWorks Simulation, designing SLA-printed optical waveguides and verifying their transmittance with a spectrometer at the Tufts DOIT Lab, or troubleshooting gear train alignment on a Scotch-yoke mechanical embosser, I enjoy working at the intersection of analytical simulation and hands-on fabrication.

Hands-On Fabrication & Campus Involvement

  • Diffuse Optics Imaging of Tissue (DOIT) Lab: Designing and fabricating compact optomechanical enclosures and custom resin light channels in SolidWorks and COMSOL.
  • Tufts Solar Vehicle Club: Hands-on composite manufacturing, including carbon fiber resin infusion for chassis components and precision wet/dry sanding (400-to-1000 grit) for the vehicle aeroshell.
  • Data & Prototyping Projects: Curated and analyzed 12 years of federal datasets in MATLAB, and designed a laser-cut/3D-printed educational game for middle school classrooms.

Outside the Lab: Watchmaking, Cooking & Baking

When I’m not in the lab or machine shop, my favorite hobbies still revolve around precision mechanics and hands-on experimentation:

  • Building Custom Mechanical Watches: Assembling mechanical watches from individual movements, dials, hands, and cases gives me a deep appreciation for micro-scale tolerances, gear trains, and intricate mechanical packaging.
  • Baking & Cooking: I treat the kitchen like a second lab—experimenting with ratios, fermentation, heat transfer, and technique to dial in recipes from scratch.
