About Me

I have broad research interests across multiple disciplines, including quantum optics, solid-state sensors, condensed matter physics, superconductivity, high-pressure physics, and materials under extreme conditions. Among these, my primary focus is on quantum sensing of superconductivity under pressure, which has recently emerged as a reliable and innovative technique. This method opens an unprecedented avenue for detecting the Meissner effect under high-pressure conditions.

Currently, I am working on developing solid-state sensors in and beyond the diamond host, as well as exploring quantum sensing in various magnetic states of novel materials.

In my spare time, I enjoy physical activities such as sports, weight training, and hiking. I also have interests in cooking, gaming, and Japanese culture.


Graduate Students

Xiaohui Liu

About Me

Interests in spectroscopy study (linear and nonlinear) over TMD fabricated devices.

I graduated from Zhejiang University in China. I chose physics as my major because it is precise and grounded in reality. More importantly, I believe that studying physics will enable me to systematically understand the world. That’s also why I enjoys arts as my hobby, as it offers another perspective.

About Me

Interests in strain quantum sensing with color defects for use in TMD heterostructures.

I am a graduate student born in Los Angeles, California. I had a wonderful teacher in high school who really inspired me to work in physics, which I continued throughout college. With my electronic experience and desire to learn about quantum computing, I merged these into the quantum sensing I work on today. I can often be found cooking, trying foods around Austin, or playing a variety of games on my computer.

Madalyn Gragg
Graduate Student
Email: mrg4867@my.utexas.edu

About Me

My research focuses on characterizing excited-state dynamics that govern charge and energy transport in 2D materials, with the goal of identifying device-level constraints to optimize optoelectronics.

I’m a graduate student originally from a small town in Eastern Oregon (~100 people) named Wamic. For my undergrad at Oregon State University, I began in engineering but was drawn to physics for its fundamental nature – especially after encountering the double-slit experiment, which sparked my fascination with quantum mechanics. This ultimately led me to condensed matter physics, a field where I could combine my engineering mindset with my intense physics curositites. For graduate studies, I merged my spectroscopy experience from undergrad with my passion for solid-state systems developed through coursework.

Outside of the lab, I enjoy cooking, baking, and watching documentaries on history and geopolitics.

About Me

Interests in exploring excited states, correlated states, and their dynamics in Van der Waals materials.

I am an undergrad at UT; I became interested in condensed matter because of how intersectional it is compared to other areas of physics. I enjoy applying concepts from pure math in my work and engaging more with chemistry and engineering via materials science. I like being more interdisciplinary where I can in my research, and I like both theory and experiment for different reasons. I also enjoy collecting dried mango pits, making weird drinks, and petting my cats.
