Professional Summary:

As Director of the Clinical Research and Consulting Lab (CRCL), the primary focus of my work is assisting residents, fellows, and junior faculty within the Department of Medline (DOM) in conducting and disseminating high quality, impactful research projects. My background and training in research methodology and statistics helps to fill the gap that many early career researchers face when trying to get a project from concept to completion. Given the nature of my responsibilities at CRCL, I do not have one specific research are of interest. I have, however, had the opportunity to work with researchers within many divisions of the DOM, and have had research published and presented at national and international conferences in the areas of behavioral medicine, nephrology, cardiology, and internal medicine, to name a few.

In addition, I also provide workshops and training (e.g., research design, statistical analysis) to assist DOM members in becoming better producers and consumers of research. We are currently developing a ‘portable’ research curriculum at CRCL that we hope will be useful research tool for all of the members within the DOM.
