About me

I am a mathematician currently working as a Research Scientist Department of Electrical and Computer Engineering, The University of Arizona. I am a Fulbright alumnus and also serve as an editor for the journal, Complex Analysis and Operator Theory. My primary area of expertise centers around mathematics of quantum theory, with a specific focus on challenges stemming from quantum information theory and my research pursuits span the interdisciplinary landscape of quantum information theory, quantum probability, and operator theory. Within the academic realm, I am actively engaged in teaching an advanced course on optical sciences, and also work as the Technical Lead for the engineering workforce development activities at the NSF Engineering Research Center, Center for Quantum Networks.
