My research focuses on understanding quantum materials in which disorder of atoms and magnetic moments generates unconventional states of matter. I use a combination of scattering experiments and atomistic modeling techniques to study the structures and behavior of these materials at the nanoscale, as part of the Basic Energy Sciences project Understanding Quantum Matter Beyond the Unit Cell. Please visit my research page for more information about my work.


I am the author of the software packages Spinvert and Scatty for modeling scattering data from spin liquids and disordered materials. Please visit my software page to download and learn more about these programs.
