Summary
👤
Senior🎓
Top SchoolTiantu Xu is a research scientist at Meta with 9 years of experience designing and building high-performance systems software for media understanding and generative AI. He holds a Ph.D. in Computer Engineering from Purdue, where his thesis produced multiple video analytics engines and a data store that ran queries hundreds of times faster than real time for city-scale and low-cost camera scenarios. At Meta he applies that systems expertise to scale LLM-driven media pipelines, bridging resource-efficient storage, retrieval, and spatio-temporal content re-identification. His background spans hands-on device-level research in applied physics and ferroelectric devices to practical AR localization and large-scale software, giving him a rare blend of low-level modeling and production systems know-how. Colleagues benefit from his focus on measurable performance gains and pragmatic orchestration of compute and storage for ML workloads.
