Trained as epidemiologist and statistician, for the past 3 years I have been involved in statistical consulting in public health and clinical research. I have been helping investigators at the school of public health and medicine to conceptualize and carry out statistical analyses, draw conclusions from the data, and write reports. I have welcomed the opportunity to work on wide variety of projects requiring expertise in various methods in biostatistics, epidemiology, and public health.

I am involved in the design and statistical analysis of a clinical trial of intracerebral hemorrhage (CLEAR III) in collaboration with the Johns Hopkins Department of Neurology Brain Injury Outcomes Services (BIOS) Division.  For this trial, I worked on the implementation of covariate-adaptive randomization to ensure balanced allocation of patients and potential risk factors between the two treatment arms.  I am also a statistician for the data coordinating center for a phase III clinical trial of minimally invasive surgery in treatment of hemorrhagic stroke, MISTIE III. The study aims to investigate prior evidence that surgical strategy might be more beneficial in the resolution of brain hemorrhage and results in better functional patient outcomes compared to conservative, standard of care, medical treatment.
