Quantum & Precision Measurements Group

We are a group of enthusiastic physicists and engineers at MIT devoted to studying the gap between quantum physics and general relativity through precision quantum measurements.


Does gravity influence quantum systems? Is gravity quantum? In our group, we study these questions using the tools of quantum and precision metrology.

Combining quantum physics and gravity is one of the greatest unresolved puzzles in modern physics. Theoretical progress is hindered by a lack of experiments, and experiments are hindered by the typical inaccessibility of the quantum gravity regime. Our group finds itself right in the middle of this vicious cycle, using precision measurements to experimentally access this regime and in turn inform theories.

Precision metrology encompasses techniques and concepts from many different fields. Our experiments make heavy use of cavity optomechanics, electromagnetism, optics, and electronics, whereas on the theory side, we think a lot about quantum physics, stochastic processes and whatever else is necessary to understand and design our experiments.

Theoretical physicists think I’m an experimentalist, while experimentalists think I’m a theorist. I try to do experiments when theory suggests that it’s time to ask nature a question.

The kind of questions that interest me are at the interface of fundamental physics (“Is gravity quantum?”), precision measurements (“What are the physical limits to measuring displacements and forces?”), and quantum control (“how can quantum systems be made to follow a desired trajectory despite the uncertainty principle?”). These interests may have been tempered by an early predilection for physics after reading ‘A Brief History of Time’ in high school, a subsequent education in electrical engineering, then theoretical quantum optics, and a PhD in quantum measurements and control. I also maintain strong ties with the MIT LIGO Laboratory, where I worked as a postdoc. 

It is my firm belief that to do beautiful science, one has to be sensitive to beauty in other spheres of activity; oil painting used to be the primary instrument to explore that, but these days, large format photography takes its place. When the sun is out, I’m also an avid cyclist.


I am a PhD student in the Department of Electrical Engineering and Computer Science at MIT.

My research in the Quantum and Precision Measurement Group focuses on macro-scale optomechanics for probing the effect of gravity on quantum systems. I am supported by an NDSEG Fellowship.

I graduated from MIT with my bachelor’s in Electrical Engineering and in Physics, and my master’s in EECS. 

Outside the lab, I enjoy reading classical literature and playing the violin and harp.

I am a PhD student in the MIT Department of Physics, also affiliated with the MIT Kavli Institute.

The central theme of my research is the usage of optomechanics and electromagnetism to shine light on quantum gravity. I’m working on the single electron experiment, and so I spend my days pondering how to manipulate an electron to give away the secrets of the Unruh effect.

I joined the Quantum and Precision Measurements Group when I started my PhD in Fall 2020. Before that, I completed a 4-year Master of Physics at the University of Oxford and pre-university education in Slovakia.

When not doing Physics, I’m usually either involved in admissions/outreach programs, baking, or playing the ukulele.
