## Bio

Dr. Granroth works as an instrument scientist on the ARCS direct geometry spectrometer at the Spallation Neutron Source. Where he studies magnetic and lattice excitations in various systems.   He has interest in exploiting event data and in the use of Monte Carlo Ray tracing to reveal subtle sample effects. He also has interests in employing advanced computational techniques for neutron data analysis, neutron instrument design, quantum and low dimensional magnetic systems, disordered magnetic systems, and neutron scattering measurements in high magnetic fields.
