Annapurna Poduri, MD, MPH

Dr. Poduri directs the Epilepsy Genetics Program 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.  Here at Boston Children's, she is also the Co-Director of the Neurology Department's Program in Neurogenetics and serves on the BEST Committee for standardizing laboratory practices.

Dr. Poduri is a key participant in epilepsy genetics research at the local and national levels. She is the Epilepsy Genetics Benchmark Steward to the National Institute of Neurological Disorders and Stroke (NINDS) and the Boston Children's Principal Investigator for the NIH-funded Epilepsy Phenome/Genome Project (EPGP), a national, multi-centered research study. She has been actively involved in data quality review and publications from the phenotyping phase of that project, and is now involved in the genotyping phase. In addition, Dr. Poduri is part of an international effort to understand the genetics of severe early-onset epilepsies.

Heather Olson, MD
Attending Neurologist

Dr. Olson is a neurologist and epileptologist at Boston Children’s Hospital with board certification in neurology and special qualification in child neurology.  She has fellowship training in epilepsy and clinical neurophysiology, as well as in neurogenetics, with a focus on epilepsy genetics.  She also has experience and interest in neonatal neurology.  She is an attending physician in the Epilepsy Genetics Program, through which she sees patients for consultations and management of epilepsy.  She sees additional patients for consultation as part of the Brain Development and Genetics Program, and she is an attending physician in the Neonatal Neurology Follow-up Program with a focus on epilepsy and neurogenetics.  Dr. Olson is also Co-director of the CDKL5 Center of Excellence.

Dr. Olson has ongoing related research projects that focus on understanding and determining the underlying genetic causes of epilepsy, including the overlap of inflammatory and genetic mechanisms of epilepsy. She has expertise in both phenotypic and genotypic analysis. She is the local contact for the Rasmussen Encephalitis Research Consortium and neurologist for The Angelman Natural History Study. In 2013, Dr. Olson was selected as the recipient of the Logan Infantile Spasms Award and Research Grant by the Child Neurology Foundation.

Gessica Truglio, PhD
Research Fellow 

Gessica Truglio joined the Epilepsy Genetics Program in January of 2014.  She is working to develop zebrafish models of PCDH19-related epilepsy. Gessica’s goals are to create a knockout of pcdh19  and also to introduce specific mutations in zebrafish to better understand the genotype-phenotype correlations in our PCDH19 patient population. She is also conducting behavioral assays and drug screening in zebrafish.

Gessica received her BS in Biological Science in 2007 and her MS in Biology Applied to Biomedical Research from La Sapienza University of Rome in 2010. She received her PhD in Biotechnology in Clinical Medicine from La Sapienza University of Rome in 2013.
