I work on numerical simulations of galaxy formation and evolution, with interests in dark matter, hydrodynamics, collision-less dynamics and gaussian random fields. You can view my publications on Google Scholar or ADS. If you're looking to use software I've written you might want to just go to my github page.
Does Self-Interacting Dark-Matter (SIDM) help explain dwarf galaxy rotation curves?
Allowing interactions (collisions) between dark matter particles causes dark matter halos to thermalise, a process which may be important in dwarf galaxies (see paper, with coauthors from UCRs particle physics group).
Gaussian Random Fields on the sphere
You can find various open-source software I have worked on on my github page. iccpy is a set of python routines for manipulating the output of cosmological simulations, created whilst working at the Institute for Computational Cosmology with Ben Lowing and John Helly. If you want to create your own cosmological initial conditions you can use lizard. Smerfs is a library for creating gaussian random fields on the sphere with a Gauss-Markov power spectrum. I'm a proponent of open science and long-time Python user and contributor to the numerical library NumPy.
