Hoang Nguyen, a graduate student in the Algorithms, Combinatorics, and Optimization Ph.D. program at the H. Milton Stewart School of Industrial and Systems Engineering, has been awarded an IBM fellowship in recognition of his research contributions and academic achievements. The IBM fellowship program is a prestigious, invitation-only award that identifies exceptional Ph.D. students conducting pioneering research in their disciplines.

Nguyen began his academic journey as an undergraduate at Minerva University, where he studied in a different country nearly every semester. This experience abroad shaped his approach to problem-solving. After graduating, Nguyen remained passionate about mathematics but became interested in applying theory to real-world challenges.

“I still wanted to do math, but I wanted to apply my mathematical research to some tangible applications,” Nguyen said. “I wanted to see the meaning behind my research.”

That desire, along with ISyE’s long-standing top national ranking in industrial engineering, led Nguyen to pursue his doctoral studies at Georgia Tech. His primary research focuses on applied probability, with an emphasis on bridging theoretical models and practical systems.

Nguyen received the IBM Fellowship in recognition of his ongoing research. One of his current research projects examines how far a process is from the steady state and seeks to better understand the finite-time behavior of the system and to make accurate real-time decisions. This work has meaningful applications in many real-world service systems models, such as the load balancing algorithms found in data centers and ride-hailing systems.

In additional his work in applied probability, Nguyen is exploring ways to improve artificial intelligence reasoning. His research investigates how large language models can verify their own outputs using mathematical heuristics and training data. By identifying and correcting discrepancies before displaying results to the user, the system could become more accurate and reliable. 

Nguyen contributes much to the mentorship of his advisor, Professor Siva Theja Magulur.

“I would like to thank my advisor, Professor Siva Theja, for supporting me through this journey,” he said. “He's an extremely caring, insightful, and attentive professor. He's also very supportive of me pursuing the AI reasoning research at Google DeepMind, although this is not his main research. Over the years, I have learned a lot from him as his student.”

The IBM Fellowship is the latest in a series of achievements for Nguyen. In 2024 and 2025, respectively, he was part of a Google DeepMind team that earned silver and gold medals in the International Mathematical Olympiad. He also won second place at the ACM SIGMETRICS 2025 Student Research Contest for his work on the finite-time behavior of queuing systems.

As he continues his doctoral studies, Nguyen remains focused on advancing his research and contributing to both theoretical and applied fields.
