Yingnan Si, a PhD candidate in biomedical engineering. This is my fifth year doing research in the University of Alabama at Birmingham (UAB). I have been working on targeted drug delivery for cancer treatment since I joined in UAB. My research interests include antibodydrug conjugate (ADC), exosome-based drug delivery, liposomal drugs, gene therapy and bioprocessing development. The disease models cover triple negative breast cancer (TNBC), neuroendocrine (NE) cancer and meningioma.
