Martin Hsu holds a B.S. in Biology from the School of Biological Sciences at the University of California, Irvine. During his undergraduate studies, Martin did undergraduate research in Agalliu’s laboratory sponsored by the Undergraduate Research Opportunities Program (UROP). Martin’s research was focused on a) examining dynamic changes in tight junctions during stroke using eGFP::Claudin-5 transgenic mice and b) visualizing blood-brain barrier leakage and infiltration of T cells in the central nervous system during recurrent infections with Streptococcus pyogenes – a human pathogen responsible for many autoimmune diseases including Sydenham’s chorea and PANDAS/PANS. During his undergraduate training in the laboratory, Martin worked closely with Daniel Knowland on the PANDAS project to map the affected regions of the brain during recurrent Streptococcal infections.
