Fall 2014 Chapter Meeting Recap

The fall 2014 regional ISES Tri-State (NJ, NY, PA) Chapter meeting was held on November 13, 2014 at the Environmental and Occupational Health Sciences Institute (EOHSI) of Rutgers University. The meeting was jointly sponsored with the Society for Risk Analysis – Metro Region. Four speakers presented on topics ranging from nanotechnology based consumer products to simulation of virtual epidemics to climate change broadly encompassing many areas of current interest in exposure science and risk analysis. The common theme and title of the seminar was “Frontiers of Public Health and Risk Management.” The joint seminar concluded with a networking reception. We look forward to our next regional meeting in spring 2015 (details TBD).

Winner of ISES Tri-State Graduate Student Travel Award: Shavonne Hylton

shavonneBeginning last year, the Chapter Council established a Student Travel Award Program to increase Chapter visibility and to support graduate student research. The award is to be presented annually as an expense reimbursement to a graduate student who attends the annual ISES Conference. The winner of the first ever travel award is Shavonne Hylton.

Shavonne demonstrates excellence in the field of exposure science through her research on the incorporation of bioaccessibility and bioavailability into oral exposure assessments for metals. This allows risk assessors to address questions surrounding the release and absorption of metals present in contaminated soils within the digestive system. While validation and standardization for these methods have and are currently being attempted by many research laboratories, a number of data gaps limit risk assessors from incorporating these measurements on a widespread scale. Shavonne’s research aims to narrow the data gaps using a three-pronged approach. First, by determining how the inclusion or exclusion of the intestinal compartment influences estimates of metal bioaccessibility. Second, most bioaccessibility measurements and validation efforts have focused on lead (Pb) and arsenic (As), limiting application of such studies outside of a case-by-case basis. Shavonne’s research aims to widen the emphasis of measurements and validation to include more metals. Finally, by incorporating a hepatocellular in vitro cellular system, target organ toxicity can be determined to get a clearer picture of what happens inside the human body post oral exposure.

Graduate Student Highlight: Sheila Tripathy, University of Pittsburg

sheilaSheila Tripathy is a PhD candidate at the University of Pittsburgh, School of Public Health in the Department of Environmental and Occupational Health. Her research with her adviser, Dr. Jane Clougherty, examines spatial and temporal patterns of particulate matter metal constituents in the greater Pittsburgh region. Specifically, she is developing land use regression models for metals (e.g., lead, manganese) from PM2.5 samples collected during a monitoring campaign in summer 2012 and winter 2013. She is using geographic information systems to assign metal constituent exposures to cohort participants within a 300 meter buffer of each participant’s residential location. Models will be developed to examine associations between metal constituent exposures and indicators of brain morphology (e.g., cortical thickness) obtained from magnetic resonance images of cohort participants.

Graduate Student Highlight: Yong Zhang, Rutgers University

Yong Zhang, a graduate student in Dr. Panos Georgopoulos’ Computational Chemodynamics Laboratory (CCL) at Rutgers University, has successfully defended his PhD dissertation. Through his thesis, “Climate Change and Airborne Allergens,” he investigated climate change impacts on allergenic pollen through statistical analysis and modeling of observed airborne pollen counts and climatic factors, and through simulation using a deterministic modeling system. A probabilistic exposure model was developed to study exposures to allergenic pollen during different past time periods across the United States. The deterministic modeling system was found to correctly predict the observed pollen season start date and duration, and airborne level at the majority of monitor stations for several different types of common pollen. The response of the allergenic pollen season to climate change was found to vary in different climate regions for different pollen taxa. For more information on Dr. Zhang’s work, you can visit Dr. Georgopoulos’ lab website. Yong has already accepted an enviable job offer as an R&D Modeling and Simulation Engineer with Proctor and Gamble (Cincinnati, Ohio). Good luck, Yong.
