Postdoctoral Scientists
Biancamaria Pierri
- Postdoctoral Research Scientist
Biancamaria obtained a Ph.D. in Translational Medicine of Development and Active Aging from the University of Salerno in Italy, where she also earned a BS and MS in Biology with honors. She conducted research at the National Reference Center for analysis and correlation study of environment, animals and humans (Zooprophylactic Institute of Southern Italy), focusing on human biomonitoring studies with a particular emphasis on DNA methylation analysis. She also contributed to multiple research projects related to COVID-19. As a Postdoctoral Research Scientist at Baccarelli Lab, her interest is to investigate molecular mechanisms underlying aging and human diseases related to environmental exposure, by implementing Next Generation Sequencing methods and exploring genetic and epigenetic modifications. She is also pursuing a postgraduate specialization school in Medical Genetics at the University of Naples Federico II (Italy). In her free time, she loves good food, traveling, dancing, and relaxing by the sea.
Wending Li
- Postdoctoral Research Scientist
Wending Li received his Ph.D. degree in Occupational and Environmental Health from Huazhong University of Science and Technology in China. He has a broad research interest in environmental, occupational, and cardiometabolic health. His main research area resides in dissecting the role of microRNAs in multiple human health conditions with an environmental origin. In his spare time, he enjoys reading, jogging, and exploring nature.
Paolo Reho
- Postdoctoral Research Scientist
Paolo obtained his PhD degree in Genetics, Cellular and Molecular Biology at the University of Pavia (Italy). He began his postdoctoral fellowship at the National Institute of Neurological Disorders and Stroke in Bethesda, Maryland. There, his work focused on uncovering the genetic and epigenetic mechanisms underlying neurodegenerative diseases. He has a genuine interest in exploring the interplay between genetics and environmental exposures in the development of human diseases and individual drug responses. In his free time, he enjoys traveling, spending time with family and friends, and watching soccer matches.
Students
Frequent Collaborators
Christina Eckhardt
- Assistant Professor, Dept. of Pulmonary Medicine
Christina earned her MD from the State University of New York Downstate College of Medicine and completed her residency training in internal medicine at Columbia University Irving Medical Center. She completed a postdoctoral research fellowship in the division of Pulmonary, Allergy, and Critical Care Medicine at Columbia and completed an MS in patient-oriented research through the Mailman School of Public Health. Her research interests include inhalational exposures and epigenetic changes as a mediator of incident lung disease. Outside of the lab, her interests include triathlons, skiing, and playing soccer.
Christian Dye
Christian Ka’ikekūponoaloha Dye's research focuses on the interface between environmental exposures and metabolic diseases, utilizing epigenetic information to develop novel biomarkers of disease risk. Further, by utilizing epigenetic data, he seeks to elucidate the potential epigenetic mechanisms of disease pathogenesis. Christian received his Ph.D. in Molecular Biosciences and Bioengineering from the University of Hawai’i at Mānoa under the mentorship of Alika Maunakea, where he focused on identifying immunoepigenetic signatures in monocytes of chronic disorders, particularly insulin resistance syndrome, type 2 diabetes mellitus, and dementia. His long-standing interest in chronic diseases stem from his passion for his Native Hawaiian community, wherein his community is disproportionately at risk to adverse health outcomes. Christian seeks to eventually bridge his work in epigenetic epidemiology with inclusive community-based research with underrepresented populations, including Native Hawaiians and Pacific Islanders.
Vrinda Kalia
- Associate Research Scientist
Vrinda Kalia received her Ph.D. in Environmental Health Sciences from Columbia University after having received her MPH in the topic from the same university. She earned her undergraduate degree in pharmacy from Rajiv Gandhi University of Health Sciences in Karnataka, India. Her dissertation work determined the metabolic consequences of proteotoxicity and exposure to the persistent pesticide DDT in the model organism, Caenorhabditis elegans. Her research focuses on using an exposomic framework to discover environmental drivers of aging. In her free time, she loves to cook, dance, and learning to animate.
