Assistant Professor

biography

My professional experience and academic training has prepared me for my current role as director of the Biostatistics and Data Management Core (BDMC). My primary responsibilities in this role are to supervise the day to day running of the core, ensure timely and exemplary data management and Biostatistical support to faculty and fellows in their cutting edge research, and to work as a collaborative biostatistician to provide a broad array of methodological and applied research endeavors related to both clinical and basic science research.

 

Area of Interest

My research interests are in joint modeling of censored longitudinal and event time data, latent group trajectory models, generalized linear models, Hierarchical Linear, survival, and clustering models, and analysis of randomized controlled trials. My recent work has led to the development of novel joint models that can evaluate the impact of one or more censored longitudinal outcomes on the survival experience of a critically ill population in the presence or absence of competing events.
