Voice-biomarker models for Parkinson's disease, validated across independent patient cohorts with calibration, domain-shift and leakage analysis. Surgical video segmentation in SurgiVision and on-device wellness signals in Anchor.

Portfolio research for the Wharton Global Youth investment competition: walk-forward models on 74 large-cap stocks, backtested from 2006 to 2026 after costs and measured against honest benchmarks.

Python and TypeScript end to end: PyTorch, LightGBM, FastAPI, React and Next.js. Reproducible pipelines, offline test suites, Docker and one-command reruns.

A surgical-vision research lab for gallbladder surgery. Built with Viraj Rungta. It segments laparoscopic video pixel by pixel, tracks anatomy and instruments from frame to frame, runs an open-source pre-op risk model, and has a simulated smart-glasses voice that reads out what the model sees. Every output is labelled real model, demo or not evaluated. A research prototype, not for clinical use.

Does a voice-based Parkinson's classifier survive new patients? Trained on one public cohort, then tested on completely independent ones: 0.88 AUC on one, 0.67 on another, lifted to 0.75 with label-free adaptation. It measures calibration and domain shift, explains predictions with SHAP, and reproduces two popular repos to show where their accuracy comes from data leakage.

A study workspace that watches out for you. Courses, assignments, notes, flashcards and a Socratic AI tutor in one place. While you work it reads posture, gaze and blink rate from the webcam and rhythm from your typing, turns them into a wellness score and a burnout forecast, and nudges you to take a break. Camera frames never leave the browser.

A stock predictor that reports what the models actually did. Built for the Wharton Global Youth investment competition. It scores 74 large-cap US stocks over 1 to 12 months, builds a portfolio for an investor profile, and backtests it over 20 years after costs. The portfolio beat the S&P 500 but lost to simply holding everything equally, and the app says so on the page.

Water-quality forecasts for US rivers. Started as a physics-informed neural network predicting nitrate risk in Alameda Creek, California, from live stream gauges, weather and satellite imagery. It now forecasts across 359 USGS stations, is validated on stations and states it never trained on, and tracks its own accuracy in a public dashboard.

Grab the cores, dodge the enemy, reach the portal. A maze-escape arcade game written in Python with pygame. Three levels, bombs, teleporters, a dash ability, and enemies that hunt you with A* pathfinding. The clip is a recording of the real game.
