Tae Bark

Biology student at UNC-Chapel Hill on the pre-dental track, building computational biology projects in Python.

◉ About Me

I study Biology at the University of North Carolina at Chapel Hill, with minors in Chemistry and Neuroscience, and I'm headed toward dentistry. Alongside clinical work as a dental assistant, I build Python projects that apply data science to health questions: how an outbreak spreads, which genes change in oral cancer, and how a tumor classifier can explain its own predictions.
