Environmental and Occupational Health Doctoral Student Profiles
Rachit Sharma, MBBS, MPH
Degrees: MBBS from University of Health Sciences, Rohtak, India; MPH from Johns Hopkins University
Rachit's Focus: Rachit Sharma is interested in investigating the health effects of air pollution and climate change, particularly in urban settings, and understanding how various psychosocial stressors may modify such effects.
Prior to starting his doctoral training, Rachit was involved in the Delhi Air Pollution: Health and Effects study as a physician-researcher. The study aimed at establishing exposure-response relationships between air pollution and adverse birth outcomes and asthma in Delhi-National Capital Region, India.
- Air pollution and climate epidemiology
- Psychosocial health
- Urban health
Yun-Ting Yen, MS
Degrees: BS in Nutrition from Taipei Medical University, Taiwan; MS in Environmental and Occupational Health from National Taiwan University, Taiwan
Yun-Ting’s Focus: Yun-Ting uses epidemiology methods along with geospatial analysis to study how environmental exposures affect human health. Her work centers on reducing health disparities in urban communities.
- Environmental Exposures
- Geospatial Analysis
- Health Disparities
- Urban Health
- Social Determinants of Health
- Risk Assessment
Professional Experience: Before starting her doctoral program, Yun-Ting worked at the GIS center at Academia Sinica in Taiwan. She collaborated in several research projects, including using GIS to study green space and type II diabetes, drug use in urban cities, and PM2.5 and mortality rates.
Ashley M. Geczik, MPH
Degrees: BS from Loyola University Maryland; MPH from Columbia University Mailman School of Public Health
Ashley's Focus: Ashley’s research is focused on how organizational safety climate is associated with occupational exposures and chronic disease outcomes among firefighters. Ashley’s research will help guide fire department leadership on ways to mitigate chronic disease risk. At Drexel, Ashley will be collaborating with the Firefighter Injury Research and Safety Trends (FIRST) Center.
In the five years Ashley has been an epidemiologist, she gained competencies in all aspects of the scientific research process: proposal writing, IRB, patient enrollment, data cleaning, analysis, and interpretation. At the NCI, Ashley studied hormonal and reproductive risk factors for cancer outcomes in men and women, producing published manuscripts and conference proceedings.
