I am now at Purdue University and open to collaborations! I also have a guest scientist appointment with the Quantum Computing Institute at ORNL. Stay tuned.

I am hiring in low-temperature physics (milli-Kelvin electronics) and material characterization. If you are interested in working with me, please email me. 


Research Theme

A significant amount of human progress has been driven by the discovery and control of materials with exceptional properties. This includes the development of modern computers which derived from the control of Silicon or the electric cars which have followed the advancement of Lithium batteries. In the past few decades, the power of material-derived electronics has grown exponentially fast as described by Moore's Law. However, it is now very apparent that the growth will slow down unless we can capture and control the quantum effects in materials that arise from quantum zero-point motion and Heisenberg's uncertainty. How do we do that? The goal of my research is to understand the quantum properties of materials towards making them useful for tomorrow's technology. My research provides insights into new quantum phenomenology in new magnetic materials both in the bulk and device geometries using reciprocal space, such as neutron scattering, and millikelvin transport techniques when the data is mapped into appropriate, preferably quantum models to capture the effects of zero-point motion, fractionalization, quantization, and coherence. 



I am teaching Physics-461, Quantum Physics II, in the Spring semester to physics Honors and masters students. My class hours are Tu/Th 1:00 - 3:00 PM. I am teaching Physics-416, Statistical Physics I, in the Fall semester to physics Honors students and masters students. Bring on the uncertainty!

Previous courses taught: Physics-172, Matter and Interactions (Freshman Engineering students) Fall, Spring - 2021,2022
