Lab Director

Colin G. Walsh, MD, MA, is an Assistant Professor of Biomedical Informatics, Medicine, and Psychiatry at Vanderbilt University Medical Center. He is a practicing internist. He received a degree in Mechanical Engineering from Princeton University and his medical degree at the University of Chicago. He completed residency and chief residency in internal medicine at Columbia University Medical Center. He received a degree in Biomedical informatics in postdoctoral fellowship at Columbia University. He joined the faculty at Vanderbilt University in 2015. His research includes: 1) applied predictive modeling to enable behavioral health and prevention; 2) scalable phenotyping for precision medicine; and 3) population health informatics to combat the overdose crisis. When he’s not working on the above, he likes to climb walls. 

Staff

 

Michael Ripperger, Application Developer

Michael received a BE in Biomedical Engineering from Vanderbilt University and, during this time, worked as an undergraduate research assistant in the Walsh Lab for two years through the SyBBURE Searle Program. He was previously a Fleming Scholar at the Oklahoma Medical Research Foundation. He is now an application developer in the lab and specializes in developing and evaluating machine learning algorithms.

 

Katey Robinson, Project Manager

Katey is a Tennessee native who grew up in Lincoln County and graduated from the University of Tennessee, Knoxville. Prior to joining the lab she spent several years as a medical scribe and project manager – she developed, implemented, and managed inpatient, ambulatory, and emergency department scribe programs for healthcare groups across the U.S. including Vanderbilt’s Department of Urologic Surgery during VUMC’s 2017 EHR transition from StarPanel to eStar. In the lab, she provides project support across Dr. Walsh’s research portfolio and facilitates day to day lab administration. 

 

Drew Wilimitis, Statistical Analyst

Drew is from Chicago, IL, and he received a Bachelor of Science in Computational and Applied Mathematics from the University of Chicago. He has a background in data science and applied machine learning, with particular interests in network science and topological data analysis. He aspires to apply mathematical methods in order to study psychology and behavioral health from first principles. In his free time, he enjoys reading philosophy, watching teen dramas on Netflix, and listening to obscure comedy podcasts.

 

 

Jhansi Kolli, Research Analyst

Jhansi is a part of the local Murfreesboro community in Tennessee. She earned her Bachelor of Science in Biochemistry from Bates College located in Lewiston, Maine. She first became interested in suicide prevention and studying rates of suicidal ideation during her work as a level three counselor with Crisis Text Line.
