Uwimana Lowami - Software Engineer & ML Specialist

About Me

Hello, welcome

I am on a path to build a career in medical image computing research. I am a graduate student at Carnegie Mellon University, Africa, where I am pursuing a master's degree in information technology. I had the privilege of joining the SPARK Academy training program where I led a team of fellow trainees to design and implement a solution for the Brain Tumor Segmentation (BraTS) challenge 2025, under mentorship of Prof. Mehmet Kurt and Prof. Udunna Anazodo.

My research interest is in generalizability of AI models and integration in clinical workflow.
