Professors Changkeun Oh (16th Fellow, Seoul National University) and Dohyun Kwon (15th Fellow, University of Seoul), both former POSCO Science Fellows, have been honored with the 2025 Sangsan Young Mathematician Award, a prestigious recognition symbolizing the next generation of leaders in Korean mathematics.

*The Sangsan Young Mathematician Award is presented to mathematicians who earned their Ph.D. within the past five years and have demonstrated outstanding achievements in the field of mathematics.

 

 

Professor Changkeun Oh of the Department of Mathematical Sciences at Seoul National University has led significant advancements in the Fourier restriction theory of harmonic analysis. His research includes the complete proof of the decoupling inequality for quadratic forms, improvements on the Bochner–Riesz problem, and the resolution of the local smoothing problem for curved averages. His groundbreaking results have been published in world-renowned journals such as Duke Mathematical Journal, Advances in Mathematics, and Peking Mathematical Journal, underscoring his academic excellence.

 

 

Professor Dohyun Kwon of the Department of Mathematics at the University of Seoul has pioneered a new research field that bridges partial differential equations (PDEs) and optimal transport theory, contributing greatly to the intersection of applied mathematics and machine learning. Using analytical methods, he has mathematically analyzed the learning processes of generative models and conducted theoretical research on the convergence and stability of cutting-edge generative models such as diffusion models. His work has been presented at top-tier international conferences, including the International Conference on Machine Learning (ICML) and Advances in Neural Information Processing Systems (NeurIPS), earning wide academic recognition.

​

The POSCO Science Fellowship is a flagship program of the POSCO TJ Park Foundation, which supports outstanding early-career scientists in Korea. Since its launch in 2009, the fellowship has selected 543 promising researchers in the fields of basic and applied sciences and has provided a total of 36.4 billion KRW in research funding, helping to foster a stable and creative research environment.
