Ann directs the Epilepsy Genetics Program at Boston Children’s Hospital as a clinician-scientist, with one hand in the clinic as a pediatric epileptologist and the other hand in the laboratory on a mission to identify the genetic underpinnings of epilepsy. She is a Professor of Neurology at Harvard Medical School, and she is the Diamond Blackfan Chair of Neuroscience Research and the Co-Director of the Neurology Department’s Program in Neurogenetics at Boston Children’s.
Ann received her BA in Biology summa cum laude from Harvard University, her MD from the University of Pennsylvania School of Medicine, and her MPH from the Harvard School of Public Health. She completed pediatric training at Boston Children’s Hospital, child neurology residency at the Children’s Hospital of Philadelphia, and clinical neurophysiology fellowship at Boston Children’s Hospital. It was through her rich clinical training that she developed research hypotheses that she pursued as a post-doctoral fellow in the laboratory of Christopher A. Walsh, where she received rich training and mentorship in dominant and recessive neurogenetics and pioneered the study of mosaic (post-zygotic) mutation in developmental brain disorders that lead to epilepsy. Ann started the Epilepsy Genetics Program at Boston Children’s in 2011 to create a translational infrastructure for clinical and research activities focused on epilepsy genetics. She started her independent research laboratory at Boston Children’s Hospital in 2013, integrating clinical research with bench laboratory research focusing primarily on the zebrafish model system.
Ann is a key participant in epilepsy genetics research at the local, national, and international level. She has been part of an international effort to understand the genetics of severe early-onset epilepsies; she served as the Boston Children’s Investigator for the NIH-funded Epilepsy Phenome/Genome Project (EPGP), a national, multi-centered research study, and Co-Investigator for the Epi4K follow-up study. She serves on the International League Against Epilepsy Genetics Commission and chairs the American Epilepsy Society/National Institute of Neurological Disorders and Stroke (NINDS) Benchmarks Stewards Committee.

She completed her pediatrics residency at the Children’s Hospital of Philadelphia followed by her neonatology fellowship in the Harvard Combined Neonatal-Perinatal Fellowship Training program. Her fellowship research focused on cohorts of patients with neurodevelopmental disorders and novel variants in the genes KDM4B, MPP5, CLCN3, and EIF4A2. She is currently a neonatology attending at Massachusetts General Hospital for Children and an Instructor in Pediatrics at Harvard Medical School. In the Poduri laboratory, Anna is using zebrafish to model rare genetic causes of neurodevelopmental disorders.
Alissa D'Gama, MD, PhD
Attending Physician, Research Fellow
Alissa joined the Poduri Laboratory and Epilepsy Genetics Program in 2021. She is a physician scientist with interests spanning neonatology, developmental neuroscience, and genetics and genomics. She received her BA in Molecular and Cellular Biology from Harvard College in 2011 and completed a combined MD-PhD program at Harvard/MIT, receiving a PhD in Biological and Biomedical Sciences under Dr. Christopher A. Walsh from Harvard Medical School in 2016 and a MD from Harvard Medical School/MIT Health Sciences and Technology in 2018. She completed pediatrics residency training in the Boston Combined Residency Program on the Accelerated Research Pathway and neonatal-perinatal fellowship in the Harvard Neonatal-Perinatal Medicine Program, where she served as Chief Fellow. Alissa is currently an attending neonatologist at Boston Children’s Hospital and her research focuses on advancing equitable precision medicine for infants with epilepsy and related neurogenetic disorders. She is co-mentored by Dr. Timothy Yu.
Sneham Tiwari, PhD
Research Fellow
Sneham joined the Poduri Laboratory and Epilepsy Genetics Program in February 2023. She recently received her Ph.D. in Biomedical sciences from Herbert Wertheim College of Medicine at Florida International University. With her background in neuroscience and molecular biology, she is interested in understanding the neurological disorders and factors involved in the abnormal functioning of the brain. Here in the Poduri Lab, she is pursuing her passion and studying epilepsy genetics with an emphasis on cellular mosaicism. She focuses on studying the somatic mutations occurring in genes of the mTOR pathway, targeting important genes that affect brain development. Sneham is interested in developing novel epilepsy zebrafish models, utilizing these models with high translational potential in deciphering mechanisms underlying neurological disorders, and translating towards high throughput drug screening and targeted efficient bioavailable therapeutics development to enhance patients’ quality of life.
Dustin Gable, MD, PhD
Research Fellow
Dustin joined the Poduri Laboratory and Epilepsy Genetics Program in 2022. He is a physician scientist and child neurologist interested in neurogenetic and neuromuscular disorders in children spanning adulthood. His roots are in rural Miller City, Ohio where he grew up on his family’s dairy farm. He went to The Ohio State University in Columbus where he completed his undergraduate degree in Biomedical Science and worked with Dr. Amanda Toland on microRNAs and genetic susceptibilities to skin cancer. He completed an MD/PhD program at the Johns Hopkins University with a PhD in Human Genetics. At Hopkins, he studied under Dr. Mary Armanios, elucidating the genetics of short telomere syndromes and pulmonary fibrosis, defining mechanisms of telomerase RNA biogenesis through generating mouse models. He completed pediatrics residency training at the Boston Combined Residency Program at Boston Children’s Hospital and Boston Medical Center and is currently completing a Child Neurology Residency at Boston Children’s Hospital. His interests in the lab include understanding mechanisms of monogenic childhood neurologic disorders through human and zebrafish models. He is currently focusing on understanding mechanisms of ankryin repeat proteins in neurodevelopmental disorders with epilepsy.
