Ayoola Ademola

Ayoola is a fourth-year doctoral student in biostatistics in the Department of Community Health Sciences at the University of Calgary. He obtained a Bachelors in Statistics from the University of Ibadan (Nigeria) and MSc in Mathematical Statistics from Georgia Southern University at Statesboro (United States). Prior to graduate school, Ayoola had over 10 years of professional experience in banking and credit risk analysis in Lagos, Nigeria.

Ayoola's doctoral research, which is jointly supervised by Drs Sajobi & Hildebrand, focuses on methodological issues that arise in the design of registry-based trials. In particular, he's exploring novel approaches for using clinical and population-based registries for the development of affordable and novel trial designs that can be used to answer important clinical questions. ​

Ayoola is also a research analyst with PrEvention of posttraumatic contractuRes with Ketotifen 2 (PERK 2) study, an international multicenter randomized controlled trial evaluating the efficacy of ketitofen in treating elbow dislocations/contractures.


Olayinka Imisioluwa Arimoro

Olayinka is a second-year master's student in the Biostatistics program. His research combines unsupervised machine learning models with item-response theory models to evaluate differential item functioning (DIF) effects in patient-reported outcome measures (PROMs).

Olayinka loves to teach and help others become better. He is a Guided Project Instructor for the Coursera Guided Project Network with over 36 courses and 63,000+ learners. 

Outside of his research and school work, he leads a not-for-profit organization, Predicare Steun Foundation, which he founded in 2018. The foundation aims to bridge the gap in the education space, particularly access to quality education,  for children between the ages of 9 and 16 years old in low-income communities in Nigeria.
