About Me

I am a medical student at Michigan State University College of Human Medicine with research interests in orthopedic surgery, surgical outcomes, and the use of advanced analytical methods to support clinical decision making.

I am also a co-founder of Mobilize Africa, a nonprofit organization that partners with institutions to deliver medical and educational resources to schools and clinics in underserved communities across West Africa.

Please feel free to reach out by email to discuss research collaborations, joint ventures, or development focused projects.

Current Projects

Machine Learning in Surgical Care

Machine Learning & Deep Learning in Surgical Care

In this project we're looking at how we can use advanced computational methods on clinical datasets to identify early predictors of postoperative complications. The goal is to improve risk stratification and decision-making in surgical care.

Gun Violence Clustering

Spatial-Temporal Clustering of Gun Violence in Detroit: A Non-Parametric Analysis

What if gun violence spread like a disease? If so, could we track its spread, identify trigger points, and intervene at the right place and time? This work uses spatial and temporal modeling of public data to study how gun violence clusters and how those patterns can guide targeted prevention strategies.

Osteosarcoma Research

Heterogeneous Treatment Effects of Surgery in Localized and Regional Osteosarcoma

Who truly benefits from surgery in osteosarcoma? This research applies causal machine learning to population-level cancer data to estimate individualized survival benefit from surgical resection. Rather than assuming uniform benefit, the analysis identifies patient subgroups with markedly different expected outcomes, offering a framework for more personalized surgical counseling.

Mask Use to Curtail Influenza in a Post-COVID-19 World: Modeling Study

JMIRx Med • 2022

A minority of individuals wearing masks substantially reduced the number of influenza infections across seasons. Considering the efficacy rates of masks and the relatively insignificant monetary cost, we highlight that it may be a viable alternative or complement to influenza vaccinations.
