Will Marella

Will is a staff associate and senior data analyst in the Robert N. Butler Columbia Aging Center. He received a BA in Biology from Brown University in 2023 and an MPhil in Population Health Sciences from the University of Cambridge in 2024. For his MPhil dissertation, he mathematically derived, developed, and analyzed a mean field variational inference algorithm and partially collapsed Gibbs sampler to optimize probabilistic modeling used to identify multimorbidities from health data. In the Belsky lab, Will is a member of the Geroscience Computational Core, where he develops key GCC packages and applies machine learning and statistical modeling to complex data types to assist a variety of aging-related research projects.
