Biography

Dr Baturalp Buyukates is an Assistant Professor at the University of Birmingham, where he is part of the Socio-Technical Systems group within the School of Computer Science. Previously, he was a postdoctoral research associate at the University of Southern California, working with Salman Avestimehr. He earned his MSc and PhD degrees in Electrical Engineering from the University of Maryland, College Park, in 2020 and 2022, respectively, under the supervision of Sennur Ulukus. Prior to that, he completed his BSc in Electrical and Electronics Engineering at Bilkent University, Turkey, in 2016.

His research interests span machine learning, generative artificial intelligence, human-centred computing, distributed systems, wireless communications, networks, and information theory. His current research focuses on reliable and explainable large language models (LLMs), privacy-preserving machine learning, responsible data economics for collaborative machine learning, timely information exchange in distributed systems, and the semantics of information.

He received the 2024 CTTC Andrea Goldsmith Young Scholars Award for his contributions to age of information, low-latency communications, distributed computation, and learning. His work has received multiple best paper recognitions, and he was awarded the George Harhalakis Outstanding Graduate Student Award from the Institute for Systems Research at the University of Maryland in 2021 for his doctoral research on timely information delivery in large networks, distributed computation, and machine learning.

In his highly interdisciplinary research, Dr Buyukates utilizes tools and techniques from optimization, machine learning, statistics, applied cryptography, and information and coding theories.
