Research Interests
My research interests focus on the many uses of statistics in public health. My devotion to statistics stems from the diversity of applications to which statistics can be applied. I came to public health after a career in telecommunications, where I was a reliability and quality engineer performing analyses analogous to “consumer reports” for telecommunication equipment.
My collaborative research currently focuses longitudinal, repeated measure and survival analysis methods in clinical trials and observational studies. Examples include:
- Myocardial Infarction and Transfusion
- Sickle Cell Disease and Cardiovascular Risk - Red Cell Exchange
- Trauma Induced Coagulopathy
- Pre-Term Birth and Cardiovascular Disease in Women
- Hemophilia Inhibitor Prevention and Eradication Trials Platform
My methodological research currently focuses Survey Sampling, Bayesian Analysis, Causal Inference, Adaptive Designs and methodology needed to support my collaborative research. This includes the following topics
- Inverse probability weight modeling
- Bayesian interim monitoring of clinical trials
- Bayesian designed clinical trials with associated simulations to identify trial characteristics
- Classification and Regression Trees
- Bayesian latent class models
- Bayesian Network Meta Analysis
My research support comes from the following sources.
- The Trans-Agency Research Consortium for Trauma Induced Coagulopathy (TACTIC, NIH/NHLBI)
- Clinical and Translational Science Institute DBE Core (CTSI-DBE, NIH/NHLBI)
- Myocardial Infarction and Transfusion (MINT, NIH/NHLBI)
- Shared Antecedents to Pre-Term Birth and Cardiovascular Disease in Women (NIH/NHLBI)
- Sickle Cell Disease and Cardiovascular Risk - Red Cell Exchange Trial (SCD-CARRE, NIH/NHLBI)

Teaching
My teaching focuses on statistical methods in epidemiology. In addition to mentoring students and participating on student committees, I teach the following courses:
- Fall Term: University of Pittsburgh, EPIDEM 2181 – Design of Clinical Trials
- Fall Term: University of Pittsburgh, EPIDEM 2215 – Teaching Practicum
- Various Terms. University of Pittsburgh: Intergroup Dialogue Workshop
To keep up to date with new teaching practices, I attend many of the CTL (center for teaching and learning) courses on good teaching practices. I specifically focus on using active learning techniques, and incorporating diversity within the classroom. I also participated in two programs to further my teaching education:
- Carnegie Mellon University – Documentation of Teaching Effectiveness – 2008
- Graduate School of Public Health – University of Pittsburgh - Certificate of Teaching Excellence – 2012
I currently advise one PhD student in epidemiology and am a committee member of five other PhD students in epidemiology. I have been primary advisor (or MPH essay advisor) for:
- Three completed PhD Epidemiology students.
- Six completed MPH Epidemiology students.
- Two completed MS Epidemiology students
In addition, I have served on 10 masters student committees (Epidemiology, Health Policy and Management, Biostatistics, and Clinical Research) and 11 PhD committees (Epidemiology, Biostatistics, Rehabilitation Science and Technology)
