Year 1

Erica Prochasta, M.D.

Erica Prochaska, M.D.

Medical school: University of Michigan Medical School
Residency: University of Pittsburgh Medical Center Children's Center
Research interests: Maternal and infant health, global health, neonatal sepsis, the maternal-fetal immune system and congenital infections


Dr. Prochaska majored in history at Carleton College and went on to complete the premedical post-baccalaureate program at Bryn Mawr College. Before entering medical school, she researched obstetric and postpartum health care use in Uttarakhand, India, through the Fulbright-Nehru fellowship. She attended the University of Michigan Medical School and completed her pediatrics residency at Children's Hospital of Pittsburgh. During the residency, she researched cytokine expression in necrotizing enterocolitis. Her current research interests are maternal and infant health, global health, neonatal sepsis, the maternal-fetal immune system and congenital infections. She enjoys running, hiking, gardening, cooking and spending time with her family.

John McAteer, D.O.

John McAteer, D.O., M.P.H.

Medical school: Kansas City University of Medicine and Biosciences College of Osteopathic Medicine
Residency: Emory University School of Medicine
Research interests: Infections in the immunocompromised host, microbial heteroresistance, neglected tropical diseases and the impact of climate change on microbial pathogenesis


Dr. McAteer is originally from the Boston area, but has traveled all around the country for medical training—first to Kansas City for medical school, then to Atlanta for residency. He comes to Baltimore with his wife, who is entering a doctoral program at Johns Hopkins University, and their dog Tessie. As the son of a microbiologist, he was born with a love for infectious diseases and is fascinated by the intersection of infectious diseases and human history. Dr. McAteer loves all of ID, but has a particular research interest in infections in the immunocompromised host, microbial heteroresistance, neglected tropical diseases and the impact of climate change on microbial pathogenesis. Prior to medical school, he pursued an MPH at Boston University, specializing in epidemiology and maternal/child health, which sparked an interest in clinical research and translational science. When not doing something related to infectious diseases, you can find him walking the dog, snowboarding, playing escape rooms or watching detective shows. “I am excited to explore all of the incredible clinical and research opportunities here at Hopkins!"

Year 2

Chief Resident

Jeanette Beaudry

Jeanette Beaudry, M.D., Ph.D.

Medical school: Columbia University Vagelos College of Physicians and Surgeons
Residency: The Johns Hopkins University
Research interests: Infections disproportionately affecting underserved populations, epidemiology, Haemophilus influenzae, malaria and global health
Mentor: Laura Hammitt, M.D.

Research Year

Dr. Jessica Rubens

Jessica Rubens, M.D.

Medical school: Boston University School of Medicine
Residency: The Johns Hopkins University
Research interests: Immune responses in measles virus infection
Mentor: Diane Griffin, M.D., Ph.D.; Diane Griffin Lab


Dr. Rubens was born and raised in sunny San Diego and moved to the East Coast to attend Davidson College in North Carolina. After college, she studied HIV pathogenesis at NIAID/NIH for two years before attending medical school at Boston University. She then moved to Baltimore to complete her pediatrics residency at Johns Hopkins University and worked for several years as a hospitalist and in research before starting her Infectious Diseases fellowship. Dr. Rubens is passionate about immunology and studies the host immune response to infections. She and her husband have lived in Baltimore for eight years now, and enjoy outdoor activities with their three young boys and dog.

Dr. Nadine Pert

Nadine Peart, M.D.

Medical school: Spartan Health Sciences University School of Medicine
Residency: Hurley Children’s Hospital
Research interests: Immune response to vaccine strain of Measles virus and mechanisms of viral RNA persistence in rhesus macaques, and therapies targeting RNA viruses
Mentor: Diane Griffin, M.D., Ph.D.; Diane Griffin Lab


Of Jamaican heritage, Dr. Peart was born and raised in New York. She has traveled to and lived in many places including St. Lucia, Chicago, Flint, Michigan, and now Baltimore. Dr. Peart and her husband love the city and enjoy raising their son in a town not far from The Johns Hopkins Hospital. They are foodies at heart, so it was very easy for them to adjust because Baltimore has tons of great places to dine. “The fellowship has afforded me an opportunity to expand my knowledge base in ways I never would have imagined and to work side by side with the experts in the field,” she says. “I have also grown to love virology, and the study of measles (my new favorite virus!) and the immune response it generates.”
