Seamus received his Bachelor’s Degree from the University of Washington and his PhD from The Johns Hopkins University, where he worked under Professor Jungsan Sohn. His graduate work focused on a class of innate immune receptors and their propensity to form filaments when activated, which suggests a way to understand certain autoimmune diseases. He then worked with Professor Sheemei Lok at Duke-NUS in Singapore, where he performed structural studies on dengue and Zika viruses and their interactions with antibodies. He joined the Moritz group in the summer of 2019.
