Born in San Juan, Sebastian has lived most of his life in the island of Puerto Rico. He majored in Industrial Microbiology at the University of Puerto Rico, Mayaguez Campus where he became a part of the local MARC program (Maximizing Access to Research Careers). Through a series of summer internships, as well as undergraduate research, Sebastian gained significant research experience in host-pathogen interactions, which motivated him to pursue a PhD in Immunology. As a current PhD student at Yale University, Sebastian currently works studying immune responses in the brain and how those responses may promote pathology under certain conditions. As a Puerto Rican and a MARC fellow, Sebastian feels a deep commitment to helping students from underrepresented groups apply to, navigate and perservere in grad school. As part of the Cientifico Latino team, Sebastian works closely with the Graduate School Preparation Initiative.
