Alumni Feature: Advancing Environmental Health Through Research, Innovation and Discovery

For Toluwanimi M. Oni, protecting communities from environmental hazards begins with understanding how the world around us influences human health.

After earning his Ph.D. in Occupational and Environmental Health from the OU Hudson College of Public Health in 2024, Oni remained at the university, where he now serves as an Assistant Professor of Research at the University of Oklahoma Health Sciences. His research focuses on reducing human exposure to environmental toxicants associated with respiratory, cardiovascular and neurological diseases.

Oni's interest in environmental health began after completing his undergraduate studies, when he participated in a health and safety course that introduced him to the science of protecting workers from occupational hazards.

"That experience sparked my interest in understanding how the environment impacts human health both within and outside the workplace," he said.

At Hudson College, Oni found a program that combined rigorous coursework with practical, hands-on experiences that prepared him to address complex environmental health challenges.

His training included using environmental sampling equipment, laboratory instruments and monitoring technologies while learning how to assess environmental hazards and develop evidence-based solutions.

"I was trained and encouraged to think creatively to proffer solutions to environmental health challenges."

For Oni, one of the greatest strengths of the Occupational and Environmental Health program was its balance of classroom instruction and research experience.

Courses incorporated active learning through discussions, field experiences and applied exercises, while his research training provided opportunities to develop skills in grant writing, scientific communication and laboratory investigation.

"Both aspects equipped me with the skills and knowledge that I now rely on in my role as an academic."

Those opportunities produced meaningful results even before graduation. During his doctoral training, Oni successfully secured three pilot project grants and published three scientific papers in peer-reviewed journals—experiences that helped launch his academic career.

Today, he continues building upon that foundation through research aimed at identifying environmental toxicants and reducing exposures that contribute to chronic disease.

His work seeks to better understand how environmental factors influence health while developing knowledge that can help protect workers and communities alike.

For prospective students considering the Occupational and Environmental Health program, Oni encourages those with a passion for improving public health to explore the many opportunities within environmental health.

He believes the field offers the chance to make a meaningful difference by identifying environmental risks before they become health problems and developing solutions that improve lives.

"The HCOPH program is well-designed to train future environmental health practitioners to address current environmental health challenges."

Looking back, Oni credits Hudson College with providing not only the technical knowledge needed to succeed, but also the confidence to pursue innovative research and tackle complex public health issues.

Through his work as a researcher and educator, Oni reflects the impact of Hudson College graduates—professionals who combine scientific discovery, hands-on experience and creative problem-solving to build healthier workplaces, stronger communities and a safer environment for future generations.
