Bio: Praneeth Vepakomma is currently a PhD student. His main research page is @ https://praneeth.mit.edu.  His research focuses on developing algorithms for distributed scientific computation & ML under constraints of privacy, communication & efficiency.  He won the Meta (previously FB) 2022 Phd Research Fellowship in Applied Statistics. He has been selected as a SERC Scholar (Social and Ethical Responsibilities of Computing Scholar) by MIT’s Schwarzman College of Computing. His FedML work won a Best Paper Award at NeurIPS 2020-SpicyFL and his work on NoPeek-Infer won a Best Paper Runner Up Award at FG-2021. He was a TA & Mentor/Coach in 2019 & 2020 for the AI for Impact Courses recognized on MIT News. He was Interviewed in the book, 'Data Scientist: The Definitive Guide to Becoming a Data Scientist'.  His work on Split Learning featured in Technology Review.  He was previously a scientist at Apple (intern), Amazon, Motorola Solutions, PublicEngines, Corning (intern) and various startups, all of which were eventually acquired. He holds an MS in Mathematical & Applied Statistics from Rutgers University, New Brunswick.
