Shakthi Visagan is a physician-engineer currently training in categorical Internal Medicine at Alameda Health System with nine years of experience spanning clinical medicine, biomedical research, and computational modeling. He holds an MD and a BS in Bioengineering and Mathematics from UCLA and St. George’s University and has applied quantitative methods—from finite element and spectral methods to diffusion MRI alignment—to neuroscience and medical imaging projects. Prior roles include building QA pipelines for MRI workflows, developing HMMs for single-cell lineage analysis, and automating behavioral neuroscience rigs, reflecting a strong blend of software, signal processing, and lab engineering. An active open-source contributor, he’s improved deep learning layers in the widely used DeepChem repository, bridging clinical insight with machine learning for biomedical applications. Colleagues often notice his knack for translating complex numerical techniques into practical tools that accelerate both research and patient care.
