Graduate Machine Learning Projects
Interpolating Accents in Text-To-Speech
This project presents a continuous-accent TTS model built on Grad-TTS, where accent embeddings are learned and applied via a diffusion framework.
- Implemented a continuous accent embedding network within the Grad-TTS architecture.
- Preprocessed and labeled Common Voice 12.0 data to enable flexible accent conditioning.
- Evaluated the model’s performance using objective metrics and a human Mean Opinion Score survey.
Graduate Mechanical Engineering Projects
CFD Decarbonization Building Study
We investigate CO₂ re-entrainment around building geometries via 2D CFD simulations, identifying optimal aspect ratios that minimize recirculation.
- Configured boundary conditions and solver settings to simulate 2D airflow and CO₂ transport.
- Ran parametric height-to-width sweeps, finding the 10×20 configuration reduced re-entrainment most effectively.
- Visualized flow fields and concentration maps to recommend geometry changes for lower turbulence.
Automated Customizable Ice Dissolving System (A.C.I.D.S)
This work develops an autonomous turret that dispenses de-icing fluid to melt ice in hard-to-reach areas.
- Conducted user surveys to define requirements and iterated through concept sketches.
- Prototyped and reinforced the structure, upgrading from servos to stepper motors.
- Implemented a Raspberry Pi–to–Arduino control pipeline for autonomous targeting and dispensing.
Undergraduate Mechanical Engineering Projects
Arm-Attachable Vise Assistant
This design integrates a two-stage gearbox into a wearable brace to reduce wrist torque by 70% when operating a vise.
- Designed a two-stage gearbox based on biomechanical torque analysis to offload user effort.
- 3D-printed and iterated components after user testing to refine fit and functionality.
- Incorporated adjustable straps and stops for various hand sizes and torque limits.
4-DOF Video Jib System
We built a modular 4-DOF jib, using FEA to optimize stiffness and weight under realistic camera loads.
- Performed FEA on arm segments to determine optimal tube dimensions for minimal deflection.
- Engineered a backlash-free pan/tilt head using preloaded bearings for smooth motion.
- Conducted cost analysis to balance material choice between weight and budget.
