Nasser Hussein Zawia
Nasser Hussein Zawia is a Yemeni-American neuroscientist, academic, and biomedical researcher specializing in pharmacology, molecular toxicology, and neurobiology. Originally from Al Bayda Governorate, Yemen, he is internationally recognized for his pioneering research on how early-life environmental exposures contribute to the development of age-related neurodegenerative disorders, particularly Alzheimer's disease.
He has served as Dean of the Graduate School and Professor of Biomedical and Pharmaceutical Sciences at the University of Rhode Island (URI), where he also played a foundational role in establishing the George & Anne Ryan Institute for Neuroscience.
Education and Academic Training
Dr. Zawia pursued his higher education in the United States, building an interdisciplinary scientific foundation that integrates biochemistry, pharmacology, physiology, and toxicology.
Academic Qualifications
- Bachelor of Science (B.S.) in Biochemistry – University of Massachusetts Amherst.
- Master of Science (M.S.) in Pharmacology and Physiology – Loma Linda University, California.
- Doctor of Philosophy (Ph.D.) in Pharmacology and Toxicology – University of California, Irvine.
- Postdoctoral Fellowship in Molecular Toxicology and Environmental Health Sciences at the National Institute of Environmental Health Sciences (NIEHS), part of the U.S. National Institutes of Health (NIH).
This multidisciplinary education established the scientific foundation for his later contributions to molecular neuroscience, environmental toxicology, and neurodegenerative disease research.
Academic Career and Leadership
Dr. Zawia began his academic career as an Assistant Professor at Sana'a University and later served as a Fulbright Scholar in Yemen before continuing his academic and research career in the United States.
At the University of Rhode Island (URI), he advanced through the academic ranks and assumed several senior leadership positions.
Leadership Positions
- Full Professor of Biomedical and Pharmaceutical Sciences.
- Dean of the Graduate School, overseeing graduate education, research strategy, and master's and doctoral programs.
- Founding Director of the Interdisciplinary Neuroscience Program.
Scientific Contributions and Research
Dr. Zawia's research has significantly advanced the field of environmental neuroscience by demonstrating how early-life exposure to environmental toxicants can influence the development of neurodegenerative diseases later in life.
Early-Life Environmental Origins of Alzheimer's Disease
His laboratory provided pioneering experimental evidence that exposure to environmental toxicants—particularly lead (Pb)—during prenatal and early childhood development can induce long-lasting epigenetic modifications. These molecular alterations remain dormant for decades before contributing to amyloid-beta accumulation, neuronal dysfunction, and the eventual onset of Alzheimer's disease during aging.
Molecular Mechanisms of Neurodegeneration
Dr. Zawia has identified molecular pathways linking oxidative stress, epigenetic regulation, RNA biology, and gene expression to age-associated neurodegeneration, expanding scientific understanding of how environmental factors reshape genetic programming throughout life.
Drug Repurposing for Neurodegenerative Disorders
Another major focus of his research involves drug repurposing, exploring new therapeutic applications for approved pharmaceuticals to slow or modify the progression of Alzheimer's disease and related neurodegenerative disorders.
Institutional Leadership and Scientific Service
George & Anne Ryan Institute for Neuroscience
Dr. Zawia played a key role in the scientific planning and institutional development of the George & Anne Ryan Institute for Neuroscience at the University of Rhode Island, helping establish it as a leading center for interdisciplinary neuroscience research.
Graduate Education and Mentorship
Throughout his academic career, he has supervised and mentored numerous master's and doctoral students, many of whom have pursued successful careers in academia, biomedical research, and healthcare institutions.
Scientific Peer Review and Editorial Activities
He has served on National Institutes of Health (NIH) grant review panels and contributed as a reviewer and editorial board member for leading international journals in pharmacology, toxicology, neuroscience, and Alzheimer's disease research.
