Imagining a better future through Engineering & Design

High-tech robots assembling a car in a modern factory setting, showcasing automation.

About Me


I am a senior Mechanical Engineering Student at Harvard University. Born and raised in Oakland California, I began experimenting with robotics and electronics in my middle school's afterschool makerspace program, flashforward to now and I've worked at Apple as a Camera Module Reliability Engineer, Ford as an Automotive Design Engineer, and done Assistive Robotics Research at the Harvard Ability Lab.

Project Spotlight


Drone V1[2025]

~500 gram 3D printed quadcopter with a 6:1 thrust to weight ratio. Specifications: 2300KV brushless motors(778 grams of thrust generated per motor), Speedybee f405 v4 flight controller+PDB+onboard ESC configured with Betaflight Firmware, 3S LiPo Battery, and PPM Receiver. In the near future, I'm planning to improve the landing gear and add an adjustable camera mount.

Self-Operating Ecosystem[2024]

Designed, fabricated, and programmed an autonomous plant care system utilizing an Arduino MKR zero, soil moisture sensor neopixels, liquid-crystal display, and 3V submersible pump. The mechanical design was done using Solidworks and 3D printers while all of the circuit was built on two small breadboards that could be enclosed in the circuit holder. The design is completely modular. The project allowed me to develop my skills with design for assembly, circuitry, Arduino, and soldering.

Portable Thermoregulated Capsule for Medicine[2025]

Built a compact cold chain management device developed as part of a consulting project for Eli Lilly. It maintains internal temperatures within the required medical range for up to 1 hour & 15 minutes, ensuring the safe transport of temperature-sensitive medications. The capsule includes a built-in display for real-time temperature monitoring, providing reliable, user-friendly functionality for critical pharmaceutical applications.

Augmented Cane[2024]

Designed an augmented cane attachment prototype to provide haptic feedback to the cane user as an undergraduate researcher at the Harvard Ability Lab.

Crankshaft & Piston[2024]

Modeled and assembled a crankshaft and piston system with CATIA V5.

Egg Drop Spring & Damping System [2024]

Developed Egg Drop Spring & Damping system using mechanical systems principles developed in ES125. We attempted to reduce the maximum acceleration and thus force that our egg experiences by modeling our system as an underdamped oscillator experiencing an initial velocity from the potential to kinetic energy conversion from the drop. From there, I utilized SolidWorks to model a system with a sufficient equivalent spring constant and damping coefficient to save our egg from demise!

Tennis Ball Grasping Robot[2023]

As a part of my Computer-Aided Machine Design class, I led my team in building a robot to participate in a robotics competition at the end of the term. The robot was completely designed and fabricated from scratch using Solidworks and the on-campus machine shop. Our design features a claw and arm mechanism I developed to interface with the play environment and stick tennis balls to the a wall to score points in the competition! We went undefeated in the competition and won first place 🥇!

Electromagnetic Safe[2023]

Designed and programmed an analog combination lock using Arduino. When the right combination is entered the user is granted access to the safe.

Acrylic Truss Bridge[2024]

Worked with team to fabricate and assemble an acrylic truss bridge to withstand high pressures in an Instron machine.

Coffee Table for My Mother[2022]

Utilized woodworking techniques to design, and construct a beautiful Japanese-inspired coffee table out of dark walnut and cherry.

Water Demand Model[2023]

As a member of Harvard's Engineers Without Borders Chapter, I utilized QGIS to model a water distribution system for a community in Los Sanchez, Dominican Republic. My model reflects the household water consumption as well as the location and altitude of each house connected to the water system.

WorldMUN 2024 Background Guide on Quantum Computing

As the chair for the disarmament and international security committee at Harvard WorldMUN 2024 in Taipei, Taiwan, I composed a thoroughly researched 29 page background guide on quantum computing and its future implications for disarmament and international security. I also moderated and judged committee sessions with over 80 highly-skilled delegates from around the world.

Multiple Linear Regression on NBA Player Data[2024]

Utilized MATLAB and Python to conduct a multiple linear regression on NBA Player Data. Our goal was to determine which factors lead players to command a higher NBA salary. Ultimately, we had to eliminate some of our variables that exhibited collinearity and those which didn't improve our model's R²(coefficient of determination). We found that height and instagram followers exhibited a strong positive correlation to NBA salary!

Home Design [2024]

Utilized architectural CAD techniques to design a 4-bedroom, 2-story home with a 2 car garage in SketchUp.
