Trained as an epidemiologist and biostatistician, I have been practicing statistical consulting for more than ten years. My research interests include observational case-based designs, design and analysis of clinical trials, and longitudinal modeling of patient-reported outcomes.

Over the years, I have collaborated with public health practitioners and clinical investigators in fields of neurology, cardiology, psychiatry, dermatology and many others. I have been involved in investigations of impact of hemorrhagic stroke on overall functioning and quality of life, the relationship between cerebral blood flow autoregulation and neurocognitive outcomes after cardiac surgery, modeling disease trajectory in children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD), bipolar disorder, and eating disorders, and, most recently, anxiety and depression in pregnancy.

Since 2011, I teach the "Introduction to Clinical Research" course offered through the Institute for Clinical and Translational Research (ICTR) to provide formal clinical research training a group of prospective investigators in wide range of clinical fields. I am also one of the principal faculty in the Graduate Training Program in Clinical Investigation, a joint venture between the Johns Hopkins Bloomberg School of Public Health and School of Medicine; it trains clinical faculty, postdoctoral fellows and other health professionals to be more effective clinical scientists by giving them skills in necessary to design and conduct clinical investigations of emerging medical treatments and technologies. I teach both in-class and on-line versions of the Quantitative Analysis of Clinical Data course.
