Priya Nagpurkar           

Priya Nagpurkar leads the Hybrid Cloud Platform and Developer Productivity mission at IBM's T.J. Watson Research Center. She leads a global team of distributed systems, programming models, and AI experts working on all interesting aspects of the cloud platform -- from serverless computing and cloud-native AI to AI for code and multicloud DevSecOps. Priya is passionate about making computing consumable.

Her previous work at IBM focused on characterizing and optimizing emerging workloads across different layers of the application and system stack, with an emphasis on language runtimes and processor architecture and design. Priya received her Ph.D. in Computer Science from the University of California, Santa Barbara in September 2007
