RSESS Graduate Student Rep

Jacklyn “Skye” Kelty, PhD

Postdoctoral Representative

Dr. Kelty is a postdoctoral scholar at Rutgers University Environmental and Occupational Health Sciences Institute, where she conducts both laboratory and community-partnered toxicology research. In the lab, she advances in vitro lung models for toxicity testing and identification of potentially vulnerable subpopulations. In the field, Dr. Kelty works in partnership with Environmental Justice communities to identify environmental health threats and prioritize interventions which address both community concerns and environmental health risks. Throughout her career, she has developed Environmental Justice community partnerships in Los Angeles, Houston, coastal LA and TX, the CA Central Valley, and NJ. Her current projects are focused on young adults including identification of subgroups with high risk of e-cigarette toxicity and evaluating the impacts of pandemic “Stay-At-Home” orders on youth environmental exposures in NJ and CA. Dr. Kelty completed her doctorate in Pharmacology and Toxicology from UC Davis in Dec 2019 where she developed lung models for testing bioactivated toxicants and was the co-principal investigator for the Knights Landing Environmental Health Project. Dr. Kelty is a current co-chair for Integrity, Diversity, and Equity for the Citizen Science Association.

RSESS Graduate Student Rep

Carmen Amelia Marable, BS, MPH

Graduate Student Representative

Ms. Marable is a full-time student in good standing enrolled in the Neuroscience PhD program at the University of North Carolina at Chapel Hill. Her scientific background is in biomedical sciences with undergraduate and graduate degrees in biology and environmental public health. She has prior experience with epigenetic studies involving the placenta and the fetal epigenome in relation to environmental contaminant exposure. For her doctoral graduate training at UNC Chapel Hill, Ms. Marable is conducting her dissertation in the lab of Dr. Rebecca Fry, a renowned leader in the field of environmental epigenetics. Ms. Marable has been able to present her work at several local and national conferences, and even at an international meeting. She hopes to continue developing her science communication skills. Serving as a Graduate Student Representative of the SOT Regulatory and Safety Evaluation Specialty Section will provide her and other students with diverse mentorship as well as unique perspectives on how to navigate communication and interactions among scientists. During her short tenure UNC so far as well as her time at the EPA, Ms. Marable has gained a deeper understanding and appreciation for scientific policy issues in the area of regulatory toxicology. This opportunity is important for young scientists in training who attend institutions where scientific and educational programs are limited. The Regulatory and Safety Evaluation Specialty Section will also offer her the chance to build an extensive network of scientists who can give insightful suggestions and advice on her thesis research and future endeavors and bring these tools back to UNC. Because she has spent time working and conducting research at the EPA prior to beginning my doctoral training she understands the desire and need for crosstalk. As a student representative Ms. Marable could assist in making sure webinar topics were selected to discuss these desired areas of interest from a student perspective. She hopes to encourage other students to explore the field that falls outside of their own niche and known interests, expanding our knowledge of regulatory and safety evaluation toxicology through various platform sessions, workshops, and webinars. This opportunity will be essential to her success, as it will provide excellent examples being both a mentee and a mentor and advocate for students, which will continuously be needed throughout her career. She hopes to pursue a career in industry or back with an agency after attaining her PhD, but because she is at the early stage of her doctoral journey, Ms. Marable is still open to exploring other opportunities.
