Research Interests

  • 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 sparse optimization, global optimization, large-scale optimization, and various optimization problems from 5G communications and big data 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.
