Trained as an epidemiologist and a statistician, for the past 7 years I have been involved in statistical consulting in public health and health research. I have been helping investigators at the Johns Hopkins Medical Institutions to conceptualize and carry out statistical analyses, draw conclusions from the data, and write reports. 

I have been involved in the design and statistical analysis of two phase III clinical trials of intracerebral hemorrhage (CLEAR III and MISTIE III) in collaboration with the Johns Hopkins Department of Neurology Brain Injury Outcomes Services (BIOS) Division. I worked on the implementation of covariate-adaptive randomization to ensure balanced on important prognostic factors between the two treatment arms.

I review statistical aspects of scientific proposals submitted to the Clinical Research Units of the Johns Hopkins Insitute for Clinical and Translational Research funded by the National Center for Advancing Translational Sciences, part of the National Institutes of Health. 

I teach an eight-week course, "Quantitative Analysis of Clinical Data" for the Science of Clinical Investigation Program at the Johns Hopkins School of Medicine and Bloomberg School of Public Health.
