RESEARCH

An ongoing independent research project that uses a variational autoencoder to generate percussive audio from hand gestures. The model builds upon RAVE, a state-of-the-art neural audio synthesis architecture, and trains on high-frame-rate recordings of conga drum performances (played by my dad) to capture fine hand movements. The goal is to make it possible to play any percussive instrument using only hand gestures and a camera.

In collaboration with researchers at the MIT Department of Mechanical Engineering and Media Lab, I developed a Stable Diffusion-based pipeline (inspired by Riffusion) for Mel-spectrogram inpainting. The model reconstructs masked audio regions, keeping optimal frequencies intact. I am currently experimenting with CLIP soft tokens to directly generate improved hydrogel music without inpainting and an audio equalizer I designed based on band performance correlations and SHAP analysis.

SwimSense is a wireless, wearable, waterproof device equipped with IMU, PPG, and temperature sensor for realtime health sensing and reporting for aquatic environments. Originally as a research collaboration with MIT Media Lab and Dept. of Mechanical Engineering, I am now independently developing SwimSense to improve comfort, battery life, and data quality. The device aims to provide swimmers and coaches with detailed insights into performance and physiological metrics during training. I also plan on adapting this device to other extreme environments where low energy, long range health monitoring is critical.

As a recreational music producer, I've tried to find "my sound" from the beginning. That mission led me to research Generative Adversarial Networks for timbre/sound synthesis in my undergraduate honors thesis at UMass Amherst. With limited time, I built a multiclass classification model for instrument identification as a foundation for future GAN-based synthesis. The long-term vision was to generate novel sounds directly from text descriptions like “soothing piano with warm overtones.” I never got to build the GAN, but I learned a lot about deep learning, audio processing, and the challenges of generative models.

PROJECTS

I designed a local Ollama-based personal assistant that summarized New York Times articles using real-time Text-to-Speech. The system refreshed its dataset daily from a live RSS feed and answered both current and historical questions stored and vectorized locally.

Originally meant to help me clean my room remotely, this three-wheel robot evolved into a PS4-controlled rover with a camera, ultrasonic sensor, and claw arm. Built with Raspberry Pi and OpenCV, it detected and grabbed 3d-printed green cubes autonomously or via controller. (Unfortunately, it never quite mastered room cleaning).

I designed a custom ESP32-based environmental controller for mushroom cultivation (the legal kind). Built on a custom KiCAD PCB, it controlled humidity, UV lighting, PC fans, and a Peltier element for heating/cooling. It also included an OLED interface and internet connectivity for monitoring.

I built the Beamshyft website to connect developers to cost-efficient interior materials. Developed with Next.js, it enabled users to request custom furnishings directly from producers. Now, the company has pivoted to focus on consumer-facing distribution, and I'm proud to have contributed to its early growth.

In high school, I wrote a Swift-based mobile app that aggregated grades, homework, and schedules. The IT department mistook it as a student privacy issue and issued a cease-and-desist. An early lesson in innovation (and red tape).

To prevent frozen pipes during winter, I built a breaker panel monitor that detected circuit trips and sent notifications via IFTTT. It was a reliable, low-cost safeguard, and far cheaper than calling an electrician... though we still did that.

Because Wordle was too easy, I created Curdle: a Wordle-style game featuring real five-letter cheese names (There are 42, in case you were wondering. And yes, it probably would have been better to include all cheeses, hangman-style). Built with JavaScript, it refreshed daily and offers a flavorful test of dairy vocabulary. Feel free to give it a try!
