### Research Interests:

**Quantum Research**

My current research focuses on everything quantum. This includes things such ranging from quantum physics to quantum engineering to quantum technology. More specifically, we focus on research around quantum information, quantum communication and cryptography, quantum networking, and linear-optical quantum computing. In addition, we look at quantum information manipulation in high-dimensional Hilbert spaces by coding, manipulating, and detecting large information clusters using group theory and topological structures. Furthermore, we look at quantum information processing, using simple quantum circuits to simulate behavior of more complicated physical systems. We also look at ultra-precise optical measurement in science and technology (Quantum Metrology), characterization of biological, organic, polymer, and semiconductor structures.
