Current Members


Nnamdi Osakwe is a Ph.D. student in Bioinformatics at NC State University. He received his B.S. in Biomedical Sciences from North Carolina Central University in Durham, NC. His research focuses on integrative data analysis to model and predict environmental integrity outcomes within specific localities. 




Jonathan Fleming is a Ph.D. student in Bioinformatics at NC State University. He received a B.S. in Biochemistry and in Mathematics from SUNY Brockport. His research focuses on using geospatial analysis to model risk factors and generate new software applications for various subjects, including disease spread and chemical toxicity. 




Melody Hancock is a Master of Bioinformatics student at NC State University. She received her B.S. in Biochemistry and Molecular Biology, with a double major in Spanish, from Mercer University in Macon, GA. Her research focuses on methods for optimizing multivariate profiling methods, such as ToxPi, for integrated analysis of toxicological and human health data. 




Dr. Adrian Green is a Postdoctoral Research Scholar in the Bioinformatics Research Center at NC State University. He received his Ph.D. in Toxicology at NC State University and his M.S. in Pharmacology and Toxicology at the University of California, Davis. He received his B.S. in Microbiology (plus a Chemistry minor) from California State University, Chico. His research focuses on identifying genes that are susceptible to environmental disturbance and play a vital role in neurobehavioral development through the application of whole genome sequencing and deep learning analysis. 



Preethi Thunga is a Ph.D. student in Bioinformatics at NC State University. She received her B.S. in Biotechnology from Anna University (India). Her research integrates data from zebrafish behavioral studies and genetically-diverse cell line experiments to understanding population responses to chemical exposure. 





altDylan Wallis is a Ph.D. student in Toxicology at NC State University. Dylan received their B.S. in Chemistry and their B.S. in Cell and Molecular Biology from the University of South Florida. Their research models gene-environment interaction (GxE) effects related to complex chemical exposures. 




altAldo Carmona-Baez is a Ph.D. student in Genetics at NC State University. Aldo received B.S. in Genomic Sciences from the Universidad Nacional Autónoma de México (UNAM). His research integrates a variety of genomic data sets to understand evolution of trophic specialization in East African cichlids and characterize effects of environmental exposures (Primary mentor Reade Roberts). 




Dr. Skylar Marvel is a Research Associate in the Bioinformatics Research Center at NC State University. He received his Ph.D. in Bioinformatics, M.S. in Biomedical Engineering (focus: tissue engineering), and M.S. in Electrical Engineering (focus: systems biology) from NC State University.
