His graduate research focused on the study of viral replication and transcription of Respiratory Syncytial Virus (RSV) under the guidance of Dr. Jose Antonio Melero at the Instituto de Salud Carlos III in Madrid, Spain. He next conducted post-doctoral research on the molecular biology of negative stranded RNA viruses, mainly influenza A and B viruses, under the supervision of Dr. Adolfo Garcia-Sastre in the Department of Microbiology at the Icahn School of Medicine at Mount Sinai in New York, USA. His current research interest at University of Rochester focuses on the molecular biology, pathogenesis, innate immune responses and vaccine development for RNA viruses, mainly arenaviruses and influenza.
