Lukman Enegi Ismaila, PhD

Summary

Research Faculty and Computational Scientist at Johns Hopkins University School of Medicine, working at the intersection of machine learning, computational neuroimaging, and healthcare AI. I design graph-based and multilayer-network models that detect subtle brain-network changes from fMRI, lead LLM and RAG work in healthcare, and serve on the engineering leadership of the Google-funded AfriMed-QA benchmark. PhD in Signals, Images, Vision (University of Angers). I care about reproducibility, interpretability, and translational impact.
