[Sep. 22, 2025] I am listed in the 2024 World's Top 2% Scientists list, both career-long and single-year categories. [link]
[Aug. 12, 2025] I’m pleased to announce the launch of my new homepage. You are welcome to visit!
My main research interests are nonlinear optimization and its applications to signal processing, wireless communications, and machine learning. I am particularly interested in characterizing the computational complexity of and designing efficient algorithms for optimization problems arising from these applications.
My current research interests are min-max optimization, large-scale optimization, stochastic optimization, and optimization in 6G communications and machine learning applications.
I am looking for self-motivated students with solid mathematical background who are interested in pursuing Master's or Ph.D. degrees. Please send me an email (with a copy of your resume) for details.
