University of Illinois at Urbana-Champaign, Materials Science and Engineering, Ph.D. candidate

Quantum dots are a type of light-emitting nanocrystalline semiconductors with applications in consumer electronics and in biological imaging. Today's best performing quantum dots are toxic when they degrade, preventing their widespread use. In order to design better, safer quantum dots we need to understand how the nanocrystal's composition, shape, size, and internal structure affect its optical properties. The overarching goal of my research is to use experimental and computational techniques to explore the structure-function relationship between these characteristics and the optical properties of nanocrystals.

University of Tennessee Knoxville, Physics, B.S., 2019
Summa Cum Laude
Chancellor's Honors Program

Kevin says modern technologies including quantum computers, transistors, and solar cells rely on semiconductor materials. Thanks to implanting small defects into the atomic pattern, semiconductors can host useful, controllable behaviors such as electrical conductivity, light sensing, and long-lived quantum information. These behaviors originate from the interplay of the electrons and atomic nuclei, but the precise role of defects in realistic systems is still under debate. Aided by first principles physics simulations and data science techniques, I will build simplified quantum models for the crystal vibrations and electronic structures in various semiconductors. These models link a system's atomic pattern to accurate descriptions of its behaviors, which can guide materials engineers when tuning semiconductors for relevant technologies.
