Timothy Watkins
About
Biography
Timothy received his BS in Biochemistry from Case Western Reserve University in 2017 and worked in structural biology research under Dr. Focco van den Akker studying soluble guanylyl cyclases. From 2017-2019, Timothy worked as a post-baccalaureate fellow at the Vaccine Research Center at NIH under Dr. Richard Koup studying B cell immortalization techniques for antibody discovery applications, particularly in HIV vaccine development. Currently, Timothy is a graduate student in the laboratory of Dr. Ellen Foxman. His work focuses on the innate immune response of human airway epithelium to a range of respiratory viruses including rhinovirus, influenza, and SARS-CoV-2. Specifically, he is interested in better defining mechanisms of interference between respiratory viruses using experimental approaches as well as analysis of clinical data and samples.
