Our group includes many talented undergraduates, graduate students, and postdocs working on exciting projects.


Dr. Swati Chaudhary studies light-driven quantum materials.  She is interested in non-linear optical responses from topological materials and other light-induced changes in band structure and topology.  She also works on non-linear phononic drives to probe and control band topology as well as magnetism through direct modification of exchange interactions.

Graduate Students

Zexun Lin is investigating how light can be used to modify the electronic and magnetic properties of materials out-of-equilibrium.  Outside of physics, Zexun enjoys painting and playing musical instruments.

Wesley Roberts is an NDSEG recipient. He is studying the influence of anisotropic magnetic exchange interactions on spin currents and exploring the real-time propagation of quantum entanglement in quenched Kitaev models.

Arpit Raj is investigating non-linear optical responses of materials with topological band structures, such as Weyl semimetals.  He is also studying optical responses from Floquet topological band structures.

Abby Postlewaite is investigating second harmonic and higher harmonic generation in materials with topological band structures. 

Undergraduate Students

Cy Elliott is studying spintronic systems. His hobbies include playing guitar, martial arts training, motorcycling, and he is President of the Northeastern Chess Club.

Jack Nedell is using machine learning to explore connections between real-space disorder in a material and the electrical conductivity.  Outside of physics, Jack is an avid hiker and regularly leads hikes.

Recent Former Group Members

Dr. Martin Rodriguez-Vega, former postdoc, studied time-dependent Hamiltonian systems with an emphasis on Floquet band structures in twisted van der Waals materials and non-linear phononic control of magnetism and topological band structure.  He has an outstanding track record of successful collaborations with a wide range of theoretical and experimental groups. He is currently an Editor at Physical Review Letters.

Dr. Bowen Ma, former PhD student, studied spin and thermal transport in magnetic insulating systems.  Of particular interest were magnetic systems with spin-orbit coupling that leads to non-collinear magnetic orders.  Such studies have implications for spin caloritronic systems.  His hobbies include detective fiction, video games, and anime.  He is currently a postdoctoral researcher at Hong Kong University.

Former PhD student Rakshanasreepriya (“Sree”) Kankanala , recipient of the Morelli Award for Excellence in Research as a first year graduate student, studied how light that selectively targets phonons can be used to modify the magnetic and topological properties of a material. She is continuing her studies in India.

Nicholas Hurley, former undergraduate in the group, studied the connection between magnetism and topology.  His hobbies include playing the guitar and rock climbing.
