Brent Andrew Coull, PhD

Professor of Biostatistics
Harvard T.H. Chan School of Public Health

Dr. Coull’s current research interests fall into the broad areas of categorical data analysis and semiparametric regression modeling. Recent topics in the analysis of categorical data include capture-recapture mixture models, random effect models for multiple discrete binary outcomes, confidence intervals for a binomial proportion, and order-restricted methods for stratified contingency tables. In the area of semiparametric regression modeling, he has focused on the development of such models for complex data structures often encountered in public health settings, such as cross-over and longitudinal settings.

 Zachary Nagel, Ph.D. 180x180

Zachary Nagel, PhD

Assistant Professor of Radiation Biology Harvard T.H. Chan School of Public Health

My research is focused on the underlying mechanisms by which cells resist killing by DNA damaging agents. This work draws from my graduate training in chemistry under Prof. Judith Klinman, which focused on the structural, chemical and biophysical underpinnings of enzyme catalysis at UC Berkeley. My graduate work resulted in several high-profile publications and two reviews that have been cited > 100 times, and my background in chemistry continues to inform current research into the mechanisms of DNA damage and repair. As a postdoctoral research associate at MIT in the Department of Biological Engineering, I worked with Prof. Leona Samson to study the role of DNA repair capacity in multiple pathways in determining how cells respond to DNA damaging agents.

Christopher Scheibler, MD, MPH, Major USAF

Chief, Occupational Medicine | Senior Flight Surgeon
United States Air Force

Christopher is Chief, Occupational Medicine and Senior Flight Surgeon for the United States US Air Force at Joint Base Elmendorf Richardson in Alaska. He recently completed the Occupational and Environmental Medicine Residency (OEMR) program for physicians at the Harvard T.H. Chan School of Public Health. At Harvard, his research focused on a comprehensive review of current research on the health impacts of commercial flight—such as circadian rhythm disruption, decreased cardiopulmonary function, and flight anxiety—on both aircrew and passengers. In a separate project, he helped evaluate the hazards of cosmic ionizing radiation and its effects on the health of aircrew and passengers, specifically looking at cancer risk and reproductive health outcomes.

Steven Staffa, MS

Steven Staffa, MS

Biostatistician IIIBoston Children’s Hospital

Steven completed his Master’s in Biostatistics from the Harvard T.H. Chan School of Public Health, where his master’s thesis was a study of health effects of textile chemicals after the introduction of new work uniforms in a flight attendant population. Steven is a Biostatistician at Boston Children’s Hospital in the Departments of Anesthesia and Surgery, and he has continued to collaborate on the Flight Attendant Health Study and the SHINE team as a Statistical Research Assistant in performing statistical analyses of health outcomes data, including investigating long-term effects of occupational second hand tobacco smoke exposure.

Dr. Sneh Manishi Toprani

Sneh Manishi Toprani, PhD

Research Fellow
Harvard T.H. Chan School of Public Health

Dr. (Miss) Sneh Manishi Toprani is a post-doctoral fellow at John B Little Center for Radiation Science, Department of Environmental Health at Harvard T H Chan School of Public Health. As a postdoctoral fellow, Dr. Toprani is responsible for leading a project that is focused on lung cancer. The major goals of this project are to understand the basis for lung cancer susceptibility and to identify new personalized strategies for radiation therapy in patients with non-small cell lung cancer. She is also a principal investigator for the project “Assessing DNA damage and repair capacity in airline flight crew” supported by Harvard-NIEHS Center for Environmental Health pilot project to test the hypothesis whether compromised genomic integrity due to air travel exposures might play a role in elevated health risk observed in flight crew.

Gerard M Turino, MD

Professor, Medicine, Pulmonary, Critical Care and Sleep Medicine
Mount Sinai Hospital

Dr. Turino came to St. Luke’s Roosevelt in 1983 as the first chairman of the newly merged St. Luke’s Roosevelt Hospital Department of Medicine from Columbia University College of Physicians & Surgeons where he was a Professor of Medicine.   After his chairmanship he became the Founding Director of the James P. Mara Center for Lung Disease at St. Luke’s Roosevelt Hospital.  The center has focused on lung matrix structure and cellular enzyme injury in chronic obstructive pulmonary disease (COPD) including alpha-1 antitrypsin deficiency (AATD) emphysema.  Studies have evolved to develop a useful biomarker for COPD and a potential therapy which is under clinical trial.
