Photini Sinnis, M.D.
Deputy Director, Johns Hopkins Malaria Research Institute
Joint Appointment in Medicine
Research Interests: Infectious diseases; Malaria
Dr. Photini Sinnis holds a joint appointment in medicine at the Johns Hopkins University School of Medicine. She is a professor of molecular microbiology and immunology with a joint appointment in biochemistry and molecular biology at the Johns Hopkins Bloomberg School of Public Health. Her research focuses on infectious diseases.
Dr. Sinnis serves as the deputy director of the Johns Hopkins Malaria Research Institute at the Johns Hopkins Bloomberg School of Public Health.
Her team is currently engaged in studying the sporozoite stage of Plasmodium, which is the infective stage of the malaria parasite.
Dr. Sinnis received her B.A. from Swarthmore College and her M.D. from Dartmouth College. She completed her residency at Columbia Presbyterian Hospital. Prior to joining Johns Hopkins, she was an associate professor at the New York University School of Medicine in the Department of Medical Parasitology and the Department of Medicine.

Research & Publications
Dr. Sinnis conducts research on the fundamental biology of the pre-erythrocytic stages of malaria. Her team is focused on the sporozoite stage of Plasmodium, which is the infective stage of the malaria parasite, and the liver stages into which they develop. Her lab uses classic biochemistry, mutational analysis, and in vitro and in vivo assays to better understand the molecular interactions between the parasite and its mosquito and mammalian hosts.
