My research focused on quantum magnetism, primarily through computational methods. I studied models of the parent compounds of the iron pnictide superconducting family and the rare earth pyrochlore spin ices. I employed a variety of monte carlo schemes, greens function methods, and ising series expansions to a proposed spin orbital model for the iron pnictides. In the case of the spin ices, I used a high temperature numerical linked cluster expansion to predict thermodynamic and magnetic properties.

I have led discussion and laboratory classes for both introductory calculus based physics for engineers/physical sciences and introductory physics for biological sciences. To be an effective teacher, I encourage students to reach answers by applying the appropriate physical concept and drawing on familiar situations to test their ideas using the scientific method. I balance leading students toward a solution and letting them experiment with applying new information. In laboratory settings I ask students to relate experimental conclusions to textbook lessons, making sure these two facets of a course reinforce each other as much as possible.

As an instructor for this summer program aimed at exposing high school students to fundamental ideas in science and mathematics, I gave short lectures and contributed to the curriculum for the biophysics section alongside UC Davis professors.The short and intensive schedule required a strict attention to student progress and the ability to quickly make adjustments when students found specific material difficult. I worked with individual students to design unique projects that applied simple physical concepts to the exciting intersection of modern computers and living organisms.I led sections three different years, 2008, 2010, 2011 - all with the same emphasis on computational biophysics.
