  • Nazar Emirov (PhD, 2020)  passed the dissertation defense. His dissertation is “Distributed algorithms and inverse graph filtering”.  He accepted a post-doctoral position at Boston College after graduation.
  • Attend the SIAM SIAM Conference on Control and Its Applications (CT19) , June 19 – 21, 2019
    at Chengdu, China and accept the 2019 SIAG/CST Best SICON Paper Prize for the paper “Sparsity and Spatial Localization Measures for Spatially Distributed Systems,” SICON 55-1 (2017), pp. 200-235, to recognize  for making “a fundamental contribution to spatially distributed systems theory, showing in particular that quadratically optimal state feedback controllers for spatially decaying systems are sparse and spatially localized.” The SIAG/CST Best SICON Paper Prize is awarded to the author(s) of the two most outstanding papers, as determined by the prize committee, published in the SIAM Journal on Control and Optimization (SICON) in the three calendar years preceding the award year. 
  • Cheng Cheng (PhD 2017) will be a postdoctoral Associate at  Duke University and SAMSI. She is supervised by Xin Li with my co-supervision.
  • Syed Alam Abbas (PhD 2017)  will be a postdoctoral research at University of New Mexico. He is supervised by Hassan Foroosh with my co-supervision.
  • Aritra Dutta (PhD 2016)  will be a Postdoctoral Researcher at the University of Edinburgh, with joint affiliation at the Visual Computing Center in KAUST, Saudi Arabia. Dr. Aritra Dutta is supervised by Xin Li with my co-supervision.
