NEW YORK - At just 28, former Grenada and OECS swimming champion Oreoluwa Cherebin has reached another milestone, successfully defending her PhD dissertation in Analytical Chemistry on Tuesday, January 20, at Indiana University in Indianapolis.
Cherebin’s dissertation, titled “Enhanced Paper-Based Electroanalytical Sensors by Leveraging Magnetic Fields,” was presented in the Department of Chemistry and Biology and supervised by her research advisor, Frederique Deiss. The work explored innovative approaches to improving low-cost, portable electroanalytical sensors, with potential applications in health diagnostics, environmental monitoring, and resource-limited settings. Her successful defence earns her the Doctor of Philosophy (PhD) degree in Analytical Chemistry.
Cherebin’s academic journey began in Grenada at St Joseph’s Convent St George, where she excelled in the classroom, sitting and passing 12 Caribbean Examinations Council (CXC) subjects, including an outstanding 11 Grade Ones. That strong academic foundation would later prove critical as she balanced elite sport with higher education.
After secondary school, Cherebin spent just one semester at the T.A. Marryshow Community College (TAMCC) before taking a bold step abroad. She joined the York YMCA Aquatic Club in Pennsylvania, where she trained at a high-performance level while simultaneously earning college credits. Her performances in the pool and discipline in the classroom soon attracted attention, leading to three scholarship offers. She ultimately chose Fairfield University, where she completed a Bachelor of Science degree in Chemistry with a minor in Mathematics.
She later earned a Master of Science degree in Analytical Chemistry from Indiana University–Purdue University Indianapolis, before continuing on to doctoral studies.
On the sporting front, Cherebin is one of Grenada’s most decorated swimmers. A product of the local Grenfin Swim Club, she is a CARIFTA, Caribbean Islands Swimming Championships (CISC) and Central American & Caribbean Swimming Confederation (CCCAN) gold medallist and represented Grenada at numerous OECS and Caribbean championships. She also competed on the global stage at the Commonwealth Games, the FINA World Championships, and the Olympic Games—a rare blend of elite international sport and academic excellence.
Cherebin credits swimming with instilling the discipline and resilience that fueled her through demanding lab work and late-night research sessions.
"Swimming taught me discipline and resilience—those same qualities carried me through the long nights in the lab," she said. "I hope young athletes in Grenada and the OECS see that sport doesn’t limit your future; it can actually expand it."
"If my journey shows anything, it’s that you don’t have to choose between academics and athletics—you can strive for excellence in both," Cherebin added.
Her mother, Pamela Cherebin, has long been an advocate for young swimmers and athletes exploring the opportunities sport can provide, while consistently stressing the importance of education. She has cautioned parents that athletic success must be matched by strong academic performance.
She also encouraged parents across Grenada and the OECS to expose children to multiple sporting disciplines at an early age. During her school years, Ore was not limited to swimming alone—she also played netball, football through the Jason Roberts Academy, participated in cycling and triathlon, and even pursued dancing, experiences that helped shape her all-round development.
“Sport can open doors, but education keeps them open. We always made it clear that academics had to come first,” she said. “I encourage parents to let their children try different sports early. You never know where their talent or passion will lead.”
“Opportunities exist, but young athletes must be prepared in the classroom to truly benefit from them," she added.
