Epidemiology and Biostatistics Core


The Epidemiology and Biostatistics Research Core (EBRC) supports Baystate faculty, fellows and residents in clinical research and research education.

We have a team of epidemiologists, statisticians, and a data scientist with Masters or PhD-level training who have broad expertise in research methods, data analysis, and scientific writing. They have a total of more than 70 years’ experience in clinical research, have published several hundred articles in major scientific journals, and handle more than 200 projects a year.
