Harrison Reeder, PhD

Harrison Reeder (he/him) is an Instructor in Investigation at MGH Biostatistics and an Instructor in Medicine at Harvard Medical School. His biostatistical research focuses on analysis methods and risk prediction tools for complex survival data, especially in the setting of “semi-competing risks.” He collaborates with multiple groups at MGH, including the Center for Addiction Medicine, and the RECOVER Project study of post-acute sequelae of SARS-CoV-2 (PASC), also known as long COVID. His collaborative research also includes work on a variety of topics including perinatal health and cognitive health in older adults. 


Dr. Reeder received his BA in Mathematics/Statistics from Carleton College and PhD in Biostatistics from Harvard University. 

David Schoenfeld headshot

David Schoenfeld, PhD

David Schoenfeld developed the first omnibus goodness of fit test for the proportional hazards regression model, a model that is used extensively in clinical trials which have survival or time to progression as an endpoint. 

He also developed widely used graphical techniques for this model. He authored a popular web site for sample size considerations for clinical trials. He has also developed, along with Dianne Finkelstein, a method of combining endpoints in clinical trials which is favored by the Food and Drug Administration, and he has done research in Bayesian methods for evaluating historically controlled trials and small pediatric trials. 

Dr. Schoenfeld was the principal investigator of the Clinical Coordinating Center for the Prevention and Early Treatment of Acute Lung Injury Clinical Network and its successor the Prevention and Early Treatment of Acute Lung Injury network, a national group doing clinical trials in Sepsis and Respiratory Failure. He is a leading statistician in Clinical Trials in Amyotrophic Lateral Sclerosis(ALS). 

Currently he is available on a per diem basis for short term consultations on the design and analysis of clinical trials.
