Jing Cui, PhD

Harvard Catalyst Profile

Jing Cui is the lead statistician in Section of Clinical Sciences in the Division of Rheumatology. Her current research focus is the application of statistical genetics to the study of RA, Lupus and Gout. She also interested in the genetic predictors of quantitative traits in RA. Dr. Cui supervises statistical programmers and data management activities, helps lead the Biometry Core, which serves the Section of Clinical Sciences and other members of the research community, consults, and performs analyses on a variety of clinical and basic science studies.


Chuan Hong, PhD

Harvard Catalyst Profile

Chuan Hong received her PhD in Biostatistics from the University of Texas Health Science Center at Houston. She is a postdoctoral research fellow at Department of Biomedical Informatics, Harvard Medical School. Her research interests lie in developing statistical and computational methods for predictive modeling, biomarker evaluation and precision medicine with biomedical data. In particular, she is interested in combining electronic medical records with biorepositories and relevant resources to improve phenotyping accuracy, detect novel biomarkers, and monitor disease progression in clinical research.


Andrew Cagan, BS

A data scientist for Partners Healthcare since 2012, Andrew has collaborated with researchers on a variety of key projects including i2b2, eMerge, PENTACON, the All Payors Claim Database, and the Partners Healthcare Biobank Portal. Prior to arriving at Partners, Andrew worked at Statusone Health Systems, and later Healthways, Inc., analyzing EMR and health insurance data while creating and improving a variety of disease management algorithms. A self proclaimed chesspert (chess expert), in his spare time Mr.Cagan can be found discussing theology with his two English Bulldogs and walking amongst his home’s exquisitely manicured gardens, practicing politics with the many marble statues that were specifically created to bare his likeness. 


Dana Weisenfeld, MS

Dana is a Research Scientist at Brigham & Women’s Hospital. Prior to joining the Brigham, she was a Research Assistant at the Center for Education Policy Research at Harvard University where she primarily helped design and analyze randomized control trials aimed at improving PK-12 student attendance.
