Derek lead the group’s research on iridate-titanate heterostructures. He developed new approaches to measure magnon dispersion and electron phonon coupling in these systems. He also worked on ultrafast RIXS and a breakthrough study about the how these systems couple to applied magnetic field. This is part of a very successful collaboration with Jian Liu’s group at the University of Tennessee.
Derek is now an Assistant Professor in the Physics Department at Oklahoma State University. You can see his website here.
