Tommy Tang

Data Scientist & Applied Machine Learning Developer

Applied AI and data science practitioner with a background in neuroscience and molecular genetics. I build machine learning, computer vision, NLP, and analytics projects that connect technical modeling with clear, real-world interpretation.

I build ML and data systems that turn messy, real-world data into interpretable decisions. My work spans biomedical image segmentation, NLP, analytics, and applied computer vision — and each case study documents the problem, approach, result, and what I would improve next.

Featured projects

A few projects that best show how I approach modeling, evaluation, and shipping.

Featured 2024

Gap Junction Segmentation in Electron Microscopy

Deep-learning segmentation pipeline for detecting thin gap-junction structures in electron-microscopy volumes.

Outcome: Example result to update — improved recall on thin structures vs. a baseline U-Net.
