Practice Areas

I discovered my passion for frame theory during my Ph.D. studies at the University of Missouri-Columbia, conducting research at the Frame Research Center under the mentorship of professor Peter Casazza. My work focuses on various problems in frame theory and its applications, including phase retrieval. After completing a three-year postdoctoral fellowship at Saint Louis University, I transitioned to my current role as an assistant professor at the same institution.
