Riley Bessetti
PhD Candidate, Department of Anatomy and Cell Biology
BS, Clarion University of Pennsylvania, 2020
Concentrations in Molecular Biology and Chemistry
Riley Bessetti is a third-year PhD Candidate in the Department of Anatomy and Cell Biology in Dr. Karen Litwa’s Lab. The Litwa Lab is interested in understanding the molecular mechanisms of synapse formation in brain development and how alterations contribute to neurodevelopmental disorders such as Autism.
Riley’s research investigates how environmental contaminants affect early synapse development and contribute to neurodevelopmental abnormalities and whether our bodies’ own antioxidant pathways can be leveraged for neuroprotection against their effects. To study this, she uses a human induced pluripotent stem cell (hIPSC) 3D organoid model of fetal brain development, also referred to as mini-brains. The Litwa Lab currently has funding from the NCSU Center for Human Health and the Environment as well as the National Center for Complementary and Integrative Health and the Office of the Director of the National Institutes of Health for her project. Riley hopes to publish her first paper from this project this summer.
Outside of the lab, Riley enjoys spending time with her boyfriend, friends, and her two dogs Bella and Sadie. She also enjoys cooking and baking and has recently begun sourdough bread making with a starter her father says is nearly 15 years old. So far, her favorite thing to make with her sourdough starter has been vanilla overnight pancakes.

Mohammed Dorgham
PhD Candidate, Department of Biochemistry and Molecular Biology, Brody School of Medicine at East Carolina University
Mohammed Dorgham is a PhD Candidate in Biochemistry and Molecular Biology in Dr. Kyle Mansfield’s Lab. The Mansfield Lab focuses on Post Transcriptional Regulation and more specifically the modification known as M6A (N⁶-Methyladenosine).
Mohammed’s research concentrate on M6A’s role in the progression of Breast Cancer via the protein Methyltransferase 3 (METTL3). He has determined that depending on the stage of the Breast cancer, removing METTL3 and therefore removing M6A can have very different effects on the phenotype of the cancer.
The Mansfield Lab was awarded a grant from the American Cancer Society for his project. He hopes to alleviate the controversy in the field in regard to M6A being shown to both suppress and promote different cancers.
When Mohammed is not in the lab, he volunteers with local youth groups at the Mosque in Greenville, North Carolina. He also is a tutor in Chemistry and Biochemistry both locally and nationally that includes in person as well as remote tutoring. He has been tutoring for several years and has a passion for teaching especially students that are underprivileged and disadvantaged.In his free time, he enjoys spending time with his wife, his family, and his friends. He likes to travel, play/watch sports as well as go camping. He has visited over 15 different countries and 25 different states and hopes to visit even more in the future.
