I study Mechanical Engineering and Computer Science at Harvard, and I’m interested in designing thoughtful hardware products and systems — from robotics to consumer devices.
Selected Projects
Harvard ES51 —Turf Wars Robot
A remote-controlled robot designed for object manipulation and pick-and-place tasks, built to compete in Harvard’s ES51 Turf Wars competition.
Keutsch Lab — Stratospheric Particle Exposure Analysis Device
A high-altitude balloon payload designed to expose and analyze particle samples under stratospheric UV, pressure, and thermal conditions in support of emerging solar engineering research.
Microrobotics Lab — MDEA Gantry
A modified gantry system that automates and safely encloses the production of multilayer dielectric elastomer actuators (MDEA) for microelectronics manufacturing.
Harvard ES50 — Glow Grid
A reactive, sensor-driven LED dance floor that responds to user interaction and logs engagement metrics, developed for Harvard’s ES51 course.

Designed multi-camera presentation array, replacing previous scan tunnels to increase item eligibility by over 25%.
- Applied DFM/DFA principles to create camera array fixture using SOLIDWORKS adhering to project requirements
- Assembled fixture prototype and subsequent design reiterations
- Evaluated performance of varying camera arrays by DOE: performing rate tests, creating heat maps of camera blindspots, and measuring item eligibility, eventually recommending a solution to AMAZON fulfillment centers
- Collaborated with external vendors to procure materials and machine precision components
Lockheed Martin Aeronautics
May - August 2023Product Quality Engineer Intern
Revamped radar processing chips manufacturing process for high manufacturing yield and quality.
- Performed a Design of Experiments (DOE) to test different parameters (e.g., pressure, temperature, resin mix)
- Used python to analyze wafer-level and package-level test data to identify trends affecting semiconductor yield
- Developed automated dashboards which enabled real-time alerts for anomaly detection to flag defective chips early
Lockheed Martin Aeronautics
August 2021 - August 2022Facility and Plant Engineer Intern
Strategized production reliability by analyzing previous equipment failures and implementing new preventative maintenance strategies.
- Developed mapping system by creating CAD asset map databases in Microstation for over 40 buildings and 300 assets at LMCO Aeronautics Headquarters
- Strategized production reliability by analyzing previous equipment failures and implementing new preventative maintenance strategies
- Created preventative capital budgets for production line equipment based on analysis of system failures & risks
Research
Harvard Keutsch Lab
Aug 2024 - PresentUndergraduate Researcher
Created an opening/closing capsule for a high-altitude balloon (HAB) system that automates the process of exposing chemical samples to the stratosphere upon ascension and safely returns to the troposphere.
- Qualified materials for UV, temperature, and pressure environments in bench, chamber, and flight tests
- Iteratively refined SOLIDWORKS assemblies and manufacturing drawings based on test data and mechanical performance feedback
- Applied Design for Assembly (DFA) and Design for Manufacturing (DFM) principles to improve system robustness and simplify fabrication
Harvard Microrobotics Lab
October 2023 - May 2024Undergraduate Researcher
Modified a 3D printer to automate multi-layered dielectric actuator elastomer (MDEA) production, a process for producing microelectronics currently performed by hand.
- Designed conceptual CAD for modified 3D printer gantry in SOLIDWORKS to account for airtight enclosure, integration of new electronics and pneumatic controls, tray sliding mechanisms, etc.
- Prototyped and assembled the modified printer using water jet, laser cutter, vertical and horizontal bandsaws, drill presses, and 3D printers
- Modified existing 3D printer Gcode to accommodate new hardware
