The Computational Health Informatics Program (CHIP) at Boston Children’s Hospital hosts a training program for postdoctoral fellows to be trained in Informatics, Genomics, Machine Learning, Artificial Intelligence, and Biomedical Data Science. The program is funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) at the National Institutes of Health (T32HD040128-16) and is open to US citizens and permanent residents.

CHIP, an affiliate of Harvard Medical School and a collaborating program of the Harvard Medical School Department of Biomedical Informatics, is recruiting postdoctoral fellows. Founded in 1994, CHIP is a multidisciplinary applied research and education program. Biomedical informatics has become a major theme and methodology for biomedical science, health care delivery, and population health, involving high-dimensional modeling and understanding of patients from the molecular to the population levels. We design information infrastructure for medical decision making, diagnosis, care redesign, public health management, and re-imagined clinical trials. The field is inherently interdisciplinary, drawing on traditional biomedical disciplines, the science and technology of computing, data science, biostatistics, epidemiology, decision theory, omics, implementation science, and health care policy and management. Our faculty are trained in medicine, data science, computer science, mathematics and epidemiology. Our faculty have been featured in The New York Times, Wall Street Journal, ABC News, CNBC, Bloomberg, CNN, Forbes, Financial Times, NBC News, GQ Magazine, U.S. News & World Report, Politico, and BBC News for their expertise on COVID-19.

We seek outstanding candidates passionate about advancing the ability to acquire and then reason over an entire spectrum of data types ranging from molecular and genomic all the way to clinical, epidemiological, environmental and social. Focus areas may include, but are not limited to research applications of machine learning/AI including COVID-19, medical applications of machine learning/AI including clinical decision support and predictive medicine, genomic and precision medicine, population health, health IT architectures and standards (e.g. SMART on FHIR apps and infrastructure), re-imagined clinical trials, real-world evidence, data visualization, and integrative omics. Candidates should have strong quantitative backgrounds.

Over the past two decades, the program has trained a mix of MDs and PhDs. More than 90 percent have gone on to receive independent funding in faculty positions in academic medicine.

The training grant favors applicants who have a strong focus on pediatric acute care, and pediatric emergency physicians are especially encouraged to apply.

Supporting Faculty - (PEMRTP Graduates) 

Chris Cassa, PhD, Assistant Professor of Medicine, HMS. His laboratory conducts research on clinical risk assessment and predictions of functional impact for genetic variants. One of the greatest challenges in the translation of clinical genetics is the analysis of germline sequence variants in genes with established disease associations. Healthy individuals often carry genetic variants in genes that have been previously associated with disease, and there is a pressing need to distinguish between causal variants that increase disease risk and those that are either incompletely penetrant or false positives.

Andrew Fine, MD, MPH, has focused his intellectual and innovative efforts on delivering clinical epidemiology, big data and digital medicine to the bedside in real time, with a focus on three major areas: clinical prediction models, clinical pathways, and clinical tools to improve efficiencies in care. His group has developed and validated models to improve the diagnosis and management of communicable diseases such as group A streptococcal pharyngitis and Lyme disease, as well as to improve clinical operations by the early prediction of the need for hospital admission among patients in the ED.

Alon Geva, MD, MPH, focuses on clinical and epidemiologic research at the intersection of pediatric critical care medicine and biomedical informatics. Incorporating methods from machine learning, NLP, and AI, he harnesses the power of “big data” to bring meaningful insight to how critical care is delivered to children, with a quality improvement lens. He also collaborates with DBMI colleagues to advance methods to improve identification of high-precision cohorts for clinical research studies.

Lois Lee, MD, MPH is a clinical researcher whose primary areas of research focus are injury prevention, trauma care, health policy and health disparities. She has published seminal research examining changes in pediatric injuries after state and federal level policy changes. In addition, her work includes examining policy changes at the institutional and state level which could potentially address health disparities in the US.

Shannon Manzi, PharmD, is HMS Assistant Professor of Pediatrics, Director of Safety & Quality, Department of Pharmacy at BCH, and Faculty in CHIP at BCH. She is the one supporting faculty member who is not a graduate of PEMRTP. However, she has advised numerous PEMRTP and T15 informatics fellows on their research. Her research areas include the application of clinical pharmacogenomics and medication safety related outcomes. The medication use process in the Emergency Medicine and Disaster Medicine settings are of particular interest, given their fast-paced, sometimes austere, environments and lack of patient history.

William Meehan, MD, MPH, is dual trained in PEM and sports medicine. A PEMRTP graduate, he pioneered a new clinical subspecialty focus, the outpatient care of children after concussive injuries, and created the Concussion Clinic at BCH during his fellowship.
