A Career in Risk Assessment: Working as a Regulatory Scientist
(PRESENTATION) [Presented : May 31, 2018]
The National Research Council (1983) identified chemical risk as a function of both inherent hazard and exposure. To address thousands of chemicals, we need to use “high throughput methods” to prioritize chemicals for additional study. High throughput risk prioritization needs: h...
A Cell Model to Evaluate Chemical Effects on Adult Human Cardiac Progenitor Cell Differentiation and Function
(PRESENTATION) [Presented : Mar 15, 2018]
Adult cardiac stem cells (CSC) and progenitor cells (CPC) represent a population of cells in the heart critical for its regeneration and function over a lifetime. The impact of chemicals on adult human CSC/CPC differentiation and function is unknown. Research was conducted to dev...
A Closer Look at U.S Environmental Protection Agency Facilities
(PRESENTATION) [Presented : Jun 05, 2018]
From the earliest days of public health, environmental protection has been fundamental to preventing disease and ensuring a healthy population. From John Snow and the Broad Street Pump to chlorinated drinking water in Jersey City, NJ, protecting the environment has been a core pu...
A Constructed Wetland for Treatment of an Impacted Waterway and the Influence of Native Waterfowl on its Perceived Effectiveness
(PRESENTATION) [Presented : May 24, 2018]
The performance of a constructed, variable-flow treatment wetland was evaluated for its ability to reduce bacterial loads from the Banklick Creek, an impacted recreational waterway in Northern Kentucky. Historically, culturable fecal indicator (coliforms and E. coli) bacteria me...
A Flexible Web-Interface for Integrating Multiple Data Streams in Support of Risk Prioritization of Environmental Chemicals
(PRESENTATION) [Presented : Mar 22, 2018]
Detailed chemical risk assessments are time-consuming and difficult to compile, leading to regulatory mandates to prioritize chemicals for further assessment. Multiple regulatory bodies (EPA, ECHA, Health Canada) are currently tasked with prioritizing chemicals for data collecti...
A Genomic Response to Trace Fear Conditioning in the Amygdala of Female Rats After Developmental Exposure to Manganese
(PRESENTATION) [Presented : Mar 15, 2018]
Increases in brain-derived neurotrophic factor (Bdnf), Ca2+/calmodulin-dependent protein kinase II alpha (Camk2a), and cyclic adenosine monophosphate (cAMP) response element binding (Creb1) gene expression have been associated with learning in a variety of different rodent studie...
A High Fat Meal After Peat Smoke Inhalation Unmasks Latent Cardiometabolic Responses in Rats
(PRESENTATION) [Presented : Mar 15, 2018]
Stress tests are used clinically to uncover underlying disease and predict future cardiovascular risk. Previously, we used treadmill exercise stress in rats to reveal latent effects of air pollution inhalation. Other daily stressors, when modeled experimentally, may have similar ...
A High-throughput Analytical Framework for Efficient Analysis of In Vitro Micronucleus (MN) Dose-response Data
(PRESENTATION) [Presented : Mar 09, 2018]
Health Canada assesses the health risks posed by chemicals in commerce in Canada. An important endpoint in chemical assessment is genetic toxicity (e.g., ability to damage DNA) which is associated with cancer and inherited genetic diseases. The in vitro micronucleus (MN) assay is...
A Historical Perspective on the Dichotomy of Arsenic as a Poison and Medicinal Agent
(PRESENTATION) [Presented : Mar 15, 2018]
Arsenic is one of the most interesting and enigmatic elements of the periodic table. Its use as an intentional poison has been known for centuries and occasionally occurs today. Arsenic has been called the “King of Poisons”, because it had been used to poison royalt...
A Physiologically-Based Pharmacokinetic (PBPK) Model With Metabolic Interactions of Chloroform (CHCL3) and Trichloroethylene
(PRESENTATION) [Presented : Mar 15, 2018]
Exposure to mixtures is frequent, but biologic pathways such as metabolic inhibition, are poorly understood. CHCl3 and TCE are model volatiles frequently co-occurring; combined exposure results in less than additive hepatotoxicity. Here, we explore the underlying metabolic inte...
A Proof-of-Concept Approach for Quantifying Multi-Pollutant Health Impacts Using the Open-Source BenMAP-CE Software Program
(PRESENTATION) [Presented : Mar 15, 2018]
Background Air pollution risk assessments often employ effect coefficients from epidemiologic studies to quantify the public health impact of changes in air quality. Partly due to data and methodological limitations, epidemiologic studies have traditionally characterized the heal...
A Sensitivity Study of Convection Parameterizations in MPAS-A Utilized in Conjunction with USEPA Physics Options
(PRESENTATION) [Presented : Jun 15, 2018]
The Model for Prediction Across Scales – Atmosphere (MPAS-A) is the meteorological foundation for a next generation global air quality modeling system currently being developed at the U.S. Environmental Protection Agency (USEPA). In recent years, meteorological fields for r...
A case study evaluation of fog simulation using two land-surface
(PRESENTATION) [Presented : Jun 15, 2018]
Despite its importance to transportation safety and ecosystem health related to pollutant and nutrient deposition, the simulation of fog lags the simulation of other meteorological phenomena due in large part to its complexity and limitations of model resolution. Accordingly, th...
A combined field-modeling study on urban soil hydrology and implications for passive green infrastructure
(PRESENTATION) [Presented : Jun 08, 2018]
Green infrastructure (GI) represents a broad set of stormwater control measures practices that can be flexibly implemented to increase sewershed retention capacity, and can thereby improve on the management of water quantity and quality. Although much GI presents as formal engine...
A glucocorticoid signaling-related adverse outcome pathway network links inhaled pollutants with multiple adverse outcomes
(PRESENTATION) [Presented : Mar 11, 2018]
The Adverse Outcome Pathway (AOP) framework represents an ideal tool for integrating diverse data relating chemical exposures to adverse outcomes. Glucocorticoid signaling is tightly controlled and numerous adverse health outcomes have been associated with either elevation or sup...
A measured approach to sustainability and other multi-criteria assessment
(PRESENTATION) [Presented : Mar 07, 2018]
From determining what to have for lunch to deciding where to invest our resources, we, as individuals and societies, are constantly involved in multi-criteria assessment. Using sustainability assessment as a case study, in this talk I will demonstrate the ubiquity of multi-crite...
