PhD Student Spotlight: Nneamaka Iwobi Researches Connections Between Toxic Exposure and Bone Development in the Sparks Lab

Nneamaka Iwobi is a third-year PhD in Pharmacological Sciences student in the UC Irvine School of Pharmacy & Pharmaceutical Sciences.

Nneamaka Iwobi is a third-year PhD in Pharmacological Sciences student in the UC Irvine School of Pharmacy & Pharmaceutical Sciences. Previously, she earned her BS in Biological Sciences with a Philosophy Certificate in Logic and Science from the University of Maryland, Baltimore County.

She entered the PhD program at UCI with the goal of expanding her understanding of pharmaceutical sciences and using her education to advance research and spearhead discoveries that will improve human health.

“I wanted to further my knowledge in a field that I have expressed interest in since high school and contribute my perspective to the ever-changing world of pharmaceutical sciences,” she shared.

Iwobi has had the opportunity to begin her research career in the lab of Dr. Nicole Sparks, assistant professor in the UCI Joe C. Wen School of Population & Public Health and affiliated faculty member of the Department of Pharmaceutical Sciences. The Sparks Lab team aims “to uncover links between environmental exposures and embryonic molecular alterations.” 

Their research incorporates stem cell biology, toxicology, molecular biology, and other approaches to study how prenatal exposure to environmental toxicants can lead to skeletal birth defects.

“Within the lab, my focus is largely on endocrine-disrupting chemicals and their effects on hormones associated with osteogenesis,” Iwobi explained.

She is looking toward professions in the biotechnology industry or government policy after she graduates in June 2027. For now, she is focused on continuing her research and taking advantage of on-campus programs and career development initiatives.

“From the classes to the rotations to the people, my experience in the PhD program has been fun!” said Iwobi. “There are challenges here and there but nothing that some reorganization and time management can’t help — it is very important to have a healthy work/life balance while doing this degree. I have also enjoyed the opportunities that have opened up since I have started the PhD, such as serving as a program representative, peer mentoring, and participating in various early career fellowships.”
