Jessie Gleason, MSPH

Degrees: MSPH from Emory University; BS from University of Pittsburgh
Focus: Jessie Gleason is interested in conducting health outcomes research to study the impact of environmental hazards on human health. Currently, her focus includes studying climate change and emerging drinking water contaminants through a health equity lens. Additional interests include using data to design and conduct evidenced-based environmental health interventions.
Professional Experience: Jessie has been with the NJ Department of Health’s Environmental and Occupational Health Surveillance Program as an environmental epidemiologist for the past 9 years. She studies areas of emerging concern around drinking water and public health including Legionella, per- and polyfluoroalkyl substances and lead. She is the Principal Investigator for CDC’s Environmental Health Capacity cooperative agreement which focuses on targeted private well testing outreach, education, risk communication and evaluation. She serves as the Chair of the Health Effects Subcommittee of the New Jersey Drinking Water Quality Institute.
Research Interests:
- Environmental Exposures
- Climate Change
- Drinking Water
- Social Determinants of Health

Amber Palmer, MPH

Degrees: MPH in Environmental Health Science and Policy from George Washington University; BS in Pharmacology and Toxicology from The University at Buffalo
Focus: Amber is interested in health risks from biological and chemical contamination of water. Her goal is to conduct research that will influence policy.
Research Interests:
- Water Quality
- Risk Assessment
- Environmental Exposures
- Built Environment
Professional Experience Before starting her doctoral program, Amber worked as an Emerging Threats Consultant focused on Hepatitis C and COVID-19 in Erie County New York. She worked on Hepatitis C surveillance for pregnant women and infants for the CDC's Surveillance for Emerging Threats to Mothers and Babies Network. She also drafted COVID-19 guidance for schools in Erie County and assisted in planning a school testing program for all schools in the county.
Annaka Scheeres, MPH

Degrees: MPH from Johns Hopkins Bloomberg School of Public Health; BS in Biology and BA in Environmental Studies (Geography concentration) from Calvin College
Focus: Annaka is interested in how climate change affects the health of urban populations and how governmental agencies can develop equitable, evidence-based strategies to promote environmental justice. Specifically, she will focus on how heat affects the physical and mental health of people living in cities and how social factors impact this relationship. She is passionate about making public health data accessible and translating public health research into policy and practice.
Professional Experience: Before starting her doctoral program, Annaka worked at the Philadelphia Department of Public Health for almost a decade. She started as a research associate focused on chronic disease, injury prevention, and the built environment, and during the COVID-19 pandemic, she helped develop systems for tracking cases and contacts. Most recently, she worked as a research scientist in the Health Commissioner’s Office, where she managed birth and death certificate data, published Philadelphia’s vital statistics on PhilaStats, and conducted population-level mortality research.

At Drexel, Theresa will be collaborating with the Firefighter Injury Research & Safety Trends (FIRST) Center.
Research Interests:
- Injury Prevention
- Emergency Preparedness
- Disaster Response
- Mental Health
Professional Experience: Theresa currently serves as an adjunct faculty member in the Public Health department at The College of New Jersey.
Prior to beginning her studies at Drexel, she served as a research coordinator at the Penn Injury Science Center, assisting in the execution of several studies focused on youth violence prevention in school settings, cultural norms on gun safety in West Philadelphia, and sport concussion recovery in college athletes.
