The Research Study

Research Team

The research team is comprised of a several groups, who all have key roles in making CARES a success. Other than the research scientists seen below, learn more about the Staff, Environmental Sampling and Sensory Bio Teams. (The staff, environmental and sensory teams will open in a new window.)

Research Scientists

Erin HaynesErin Haynes

Dr. Haynes’ primary research interest is to examine the effect of low-level toxicant exposures on neurobehavioral outcomes. Specific research interests include evaluating biological and health outcomes in children resulting from exposure to multiple metals, such as lead and manganese, evaluating gene-environment interactions that may influence the neurobehavioral effect of metal exposure, and increasing public knowledge of environmental toxicants that threaten public health. She is currently working on an NIEHS-funded R21 to study the neurobehavioral effects of low level manganese exposure. She is also the Director of the Master of Science in Clinical Research Training Program.

Kim DietrichKim Dietrich

Dr. Dietrich serves as Director of the Division of Epidemiology and Biostatistics and Associate Director of the Cincinnati Children's Center for Environmental Health. His research has focused on the developmental effects of prenatal and early postnatal exposure to lead in infants, toddlers, school-age children, adolescents and adults. His studies also include an examination of the developmental benefits of chelation therapy with succimer in a multicenter clinical trial. Dr. Dietrich is examining the effects of prenatal exposure to prevalent developmental toxicants including lead, pesticides, mercury, PCBs, tobacco smoke, and alcohol in a Tri-State birth cohort of over 400 infants. Dr. Dietrich also directs neurobehavioral assessments in a study of atmospheric metal exposures in a school-age cohort study in Southeastern Ohio. He is also involved in studies examining early risk factors for the later development of breast cancer in a cohort of community dwelling prepubescent girls with and without a family history of the disease.

Paul SuccopPaul Succop

Dr. Succop’s research interests are in the areas of multivariate analysis, specifically structural equations modeling; and the study of techniques for handling missing data. He has also studied methods for transforming non-normal data and the use of the method of moments for transformation or parameter estimation for non-normally distributed data. Another recent interest is the development of methods for employing empirical likelihood for producing nonparametric tests of statistical hypotheses.



Tiina ReponenTiina Reponen

Dr. Reponen’s research is focused on the exposure assessment of bioaerosols in indoor and industrial environments, including physical and microbiological characterization of airborne actinomycete and fungal spores, the dispersion of bioaerosols under natural and laboratory conditions, and the control of airborne microorganisms by filtration. She is a Certified Indoor Air Quality Professional and is currently a co-investigator of a 5-year project studying the effect of traffic pollution and bioaerosols on the development of children’s allergies and asthma.

Patrick RyanPatrick Ryan

Dr. Ryan's research focus is primarily related to air pollution epidemiology, and in particular, the development and application of spatial models using geographic information systems (GIS) for exposure assessment. Dr. Ryan is currently involved with the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS), a longitudinal birth cohort whose purpose is to determine if children exposed to diesel exhaust are at increased risk for the development of allergic disease and asthma. In addition, Dr. Ryan is involved in several other environmental and occupational epidemiologic studies including the analysis of the elemental composition of PM2.5, exposure to traffic-related air pollution at schools, exposure to ambient manganese and neurobehavioral development, and exposure to erionite in North Dakota.

Amit Bhattacharya


Professor Amit Bhattacharya, Ph.D., CPE, is trained in the field of mechanical engineering with specialization in biomedical engineering and stress physiology. A majority of his research activities involved collaborative projects with researchers having a wide range of expertise such as, biomechanics, engineering, medicine, physiology (human and animal), epidemiology, toxicologist, neuropsychologist and genetics.  His recent research interest in collaboration with faculty in neurology, geriatric medicine, BioMEMS/nano-technology engineering, population epidemiology and genomic information center, has focused in the areas of 1) Early/sub-clinical detection of human health/impairment when exposed to multiple risk factors of chemical (e.g. exposures to neurotoxic agents), physical (workload, physical environment) as well as personal (age, obesity, genetic) origin.

Mary BarnasMary Barnas

Dr. Barnas is a developmental psychologist specializing in social-emotional development in children with a specific emphasis on family violence. Her current work involves running a Supervised Visitation Center where children from abusive or violent homes visit with their parents in a controlled environment. Upper level psychology students can take a course in family violence and intern at the center as a part of their studies. She developed a new program at Marietta College and opened the Center for Families and Children on campus in the spring of 2004. Read more about Mary...

Carolien BeidlerCaroline Beidler

Caroline Beidler is the founder of Neighbors for Clean Air, the Marietta community initiative that first alerted the local scientific community to the poor air quality in this Southeastern Ohio community. When Dr. Erin Haynes took an interest in the potentially dangerous Marietta air, she called on Caroline to help elucidate the concerns of a community to a group of researchers. The partnership grew into the CARES study, a synergy of concerned citizens and trained researchers working together to improve air quality and better understand the results of manganese exposure. Now Caroline is a fixture on the CARES team, acting as the study's research assistant, heading up the Environmental Sampling Team, and serving as the liaison between concerned Marietta citizens and the CARES team, all in the name of clean air.

Bruce Lanphear

Bruce Lanphear

Dr. Lanphear’s interests include an ongoing neurobehavioral effects study of low-level lead exposure in Rochester, NY; a randomized controlled trial to reduce children’s exposure to environmental tobacco smoke. Along with others, he is investigating Vitamin D receptor Fok1 polymorphism as a predictor of children’s blood lead concentration. As Director of the Children’s Environmental Health Center, he is examining the effect of prevalent neurotoxicants, such as lead, tobacco smoke exposure, pesticides, PCB’s and mercury.

David Brown

David Brown

Dr. Brown is an instructor in classes ranging from modern biology and cellular and molecular biology to environmental toxicology. He was the Director of Research for Xenobiotic Detection Systems Inc. from 1995-2002. There he developed high-throughput cell-based bioassays for the detection of environmental contaminants and promoted the use of bioassays as a more direct measure of biological risk. He was the President/Founder of Coastal Explorations Inc. in Beaufort, N.C., a company that developed 10 instructional programs focused on marine environment that incorporated North Carolina science curriculum requirements. He is a member of the Society of Environmental Toxicology and Chemistry.
