Our Team

Principal Investigator

Jonathan Schneck, M.D. Ph.D.

Jonathan Schneck (Professor of Pathology, Medicine and Oncology) received his M.D. Ph.D. in Immunology from the Albert Einstein College of Medicine. After completing his degree, Dr. Schneck trained in Pediatrics at the Children’s Hospital National Medical Center in Washington DC. From there he went to the National Institute of Allergy and Immunology at the NIH in Bethesda and did his postdoctoral training at the Laboratory of Immunology. He joined the faculty at JHMI in 1990 as a junior faculty and is currently a Professor in Pathology, Medicine and Oncology. His lab is focused on T cell immunology in the Department of Pathology. When not in lab, Dr. Schneck is a family man with 5 children. Dr. Schneck enjoys skiing and photography.

Research Associates

Joan Glick Bieler, Ph.D.

Joanie received her Ph.D. in hematology from the City University of NY. Next, she did a post-doc in viral oncology investigating early onco-genes at Memorial Sloan Kettering. After a career detour which included teaching, child rearing and baking, Joanie joined the Schneck lab where she concentrated on mechanisms of TCR/MHC/peptide interaction and the dynamics of the immune response and helped develop the protocols used in enrichment and expansion by aAPC. After a short hiatus, Joanie has returned to apply some of the lab’s methodologies to clinical problems of transplant rejection and infection following immune-suppression. Joanie spends most of her time outside of lab either with family or baking. Sometimes the lab benefits from her baked goods production.

Postdoctoral Fellows

Shuyi Li, Ph.D.

Shuyi Li is a postdoctoral fellow. She received her Ph.D. in Physical Chemistry from the National Center of Nanoscience and Technology of China. Her research mainly focuses on developing nanoparticle and hydrogel platforms for generating and expanding tissue resident memory T cells for cancer immunotherapy. Outside of the lab, Shuyi likes cooking, baking, and watching movies.

Ted Kouo, M.D.

Ted Kouo is a clinical fellow in Pediatric Emergency Medicine. He was in the Medical Scientist Training Program (MSTP) at Johns Hopkins from 2006-2015, and completed his Ph.D. in Dr. Elizabeth Jaffee’s lab where he studied the role of galectin-3 modulating tumor specific CD* T cell responses after cancer vaccination. He remained at Hopkins to complete his residency in pediatrics from 2015-2018. Ted’s current research interests are in applying the aAPC platform to investigate the impact of childhood disease and trauma on cellular immunity.
