Dr. Walpita earned her PhD from the University of London, England. Before joining UH, she was a Senior Research Scientist at the Pharmaceutical Company Wyeth Vaccines (currently Pfizer), and more recently a Research Faculty at University of Texas Medical Branch. Her research interests include vaccinology, molecular biology, immunology, and pathogenesis of paramyxoviruses. Her current research is focused on developing virus-like particle (VLP)-based vaccine for two of the paramyxoviruses, Nipah virus and respiratory syncytial virus. She is pursuing studies to understand how VLPs are sensed by the host and the nature of innate immunity induced as a result. She is also interested in the ultrastructural make-up of varying VLPs with the aim of maximizing their therapeutic potential. An additional interest is in evaluating the molecular mechanisms of transcription and replication control of viruses in the Paramyxovirinae subfamily.
Her research interests include: Vaccines, Host-pathogen interactions, T cell priming Cytokines/Chemokines and Pathogenesis of Paramyxoviruses.
