Hannah is a PhD student in the Center for Neuroscience at the University of Pittsburgh, working in Dr. Baoli Hu's lab. Her research focuses on identifying and characterizing therapeutic targets in glioblastoma, examining how they drive mesenchymal subtype identity and shape the tumor immune microenvironment. Hannah is passionate about the biotech ecosystem in Pittsburgh, and channels this through her involvement as a member of Nucleate and Fourth River Solutions. In her free time, Hannah enjoys running and playing with her cat.
