Dr. Sameera Abuaish – د. سميرة أبوعيش

Dr. Sameera Abuaish is an assistant professor at the Department of Basic Science at the College of Medicine in Princess Nourah Bint Adulrahman University. She studies how different early-life environments affect different aspects of neurobiology (behaviour, physiology, and molecular biology) in individual in both rodent models and humans.

She has obtained her PhD degree in Cell and Systems Biology from the University of Toronto in Canada. During that time she was a member in Dr. Patrick McGowan’s laboratory studying the effects of maternal obesity and stress on offspring anxiety behavior, neuroendocrinology, and epigenetics.

Previously, she completed her MSc. in Cellular and Molecular Medicine from the University of Ottawa, where she was a member in Dr. David Park’s laboratory working on identifying genetic interactors of one of Parkinson’s disease genes (LRRK2), using a Drosophila melanogaster genetic screen. She graduated Cum Lauda from the University of Ottawa with a Bacholar’s degree with Honors in Biology with specialization in cellular and molecular biology with a minor in Psychology.

Througout her education she was keen to understand how the brain works in health and disease using different animal models. She continous to explore this further in her research.

Dr. Abuaish’s research interst is examining early life maternal environmenatl factors in shaping the health outcomes of individuals with specific focus on neuroendocrinology. She dose that mainly in animal models, however she is keen in translating knowledge obtained from animals to humans. Her approach is to integrate several biological levels from behaviour and physiology to molecular changes in gene expression to understand the health and disease in these models.

Research Expertises:

• Animal models of obesity and neuropsychatric disorders
• Animal behavior (several behavioral tests in rodents)
• Animal physiology (RIA and ELISA)
• Gene expression and DNA methylation (qPCR, pyrosequencing, RRBS)
• Brain anatomy (microdissection)
