Personal Overview
My principal research interests are in the areas of optimization, machine/deep learning, and data analytics. My research is mainly focused on designing models and algorithms with theoretical performance guarantees for challenging problems arising in imaging informatics and data analytics leveraging computational optimization techniques and machine/deep learning methods.
I joined the Department of Mathematical Sciences at Florida Institute of Technology as a tenure-track assistant professor in 2021. Prior to this, I was a postdoctoral research fellow at the Department of Radiology, Mass General Hospital, Harvard Medical School from 2018 to 2021. I received my Ph.D. Degree in Applied Mathematics from the Department of Mathematics at University of Florida under the supervision of Prof. Yunmei Chen in May, 2018. My thesis Topic is "Fast first-order optimization methods with applications to inverse problems". I also obtained a master degree from the Department of Electrical and Computer Engineering at University of Florida in May, 2015 with speciality in machine/deep learning.
I am looking for highly-motivated students who are interested in working with me on any topics mentioned above. Please feel free to shoot me an email at xli@fit.edu if you are. We will have a wonderful and fun research journey by collaborating with each other.
