Information Systems & Modeling
Los Alamos National Laboratory
Intro
I received my PhD in Physics from Tulane University where, as a Louisiana Board of Regents Graduate Fellow, I studied the effects of chemical substitution on strongly correlated electron materials using advanced materials synthesis techniques.
Shortly thereafter I joined the Neutron Scattering Group in CMPMSD at Brookhaven National Laboratory, where I investigated the lattice dynamics in iron-based superconductors using neutron spectroscopy, and assisted in the development of a new scattering instrument at Oak Ridge National Lab, HYSPEC. As a former member of MPA-CMMS at Los Alamos National Lab, I am used neutrons to study how magnetic frustration and anisotropy affect emergent phases observed near superconductivity, and the spin dynamics of skyrmion lattices.
My work has generated considerable impact in my field; my more than thirty publications, appearing in journals such as Nature Physics, Nature Materials, and Nature Communications, have already been cited nearly six hundred times. My broader research interests include the complex role of magnetic interactions in quantum materials, which have the potential for future functionality, and machine learning for materials research.
I currently work in the Information Systems and Modeling (A-1) Group at Los Alamos National Laboratory (LANL), working on optimization for critical infrastructure.

2015 – 2018
Los Alamos National Laboratory
Postdoc Research Associate
Los Alamos, NM
Investigation of the magnetism dynamics of heavy fermion compounds and skyrmion materials using neutron spectroscopy, discovering an intimate connection between the modulated magnetic states of CeRhIn5 and its high nematic susceptibility, and making the first measurements of the spin excitation spectra of skyrmion compound MnSi via neutron Time of Flight spectroscopy. Also designed and successfully tested a versatile new uniaxial strain device for use in small angle neutron scattering
2012 – 2015
Brookhaven National Laboratory
Research Associate
Upton, NY
Study of the lattice dynamics in the iron chalcogenide superconducting family Fe(1+y)Te(1-x)Se(x) using neutron scattering, finding evidence for an orbital ordering transition in parent compound FeTe, appearing as a Bond-Order-Wave, and for an intimate coupling between magnetic fluctuations and the lattice degree of freedom resulting in the appearance of a "forbidden" phonon. Also participated in the comissioning of a hybrid spectrometer (HYSPEC) at Oak Ridge National Lab's Spallation Neutron Source, and began developement of NeutronPy
