<h2>Asymmetries in Magellanic Galaxies</h2>
<p>My thesis project studies the role of interactions in causing the asymmetries in Magellanic Galaxies. See my recent <a href="http://arxiv.org/abs/1602.07689">paper</a> about tidally induced asymmetric-disks and how they masquerade as offset bars in Magellanic Galaxies.</p>

<h2>Tidal Streams as a Probe of Dark Matter</h2>
<p>As a 2014 fellow at the <a href="http://isima.ucsc.edu/">International Summer Institute for Modeling in Astrophysics</a>, I worked with Andreas Küpper on modeling the tidal stream of NGC 5466. Tidal streams act as unique probes of the dark matter halo of their environments. This work, along with new data from Jay Strader, will place strong contraints on the shape and total mass of the Milky Way. We use a Markov chain Monte Carlo to probe parameter space, where the likelihood function is drawn in real time from very efficient restricted N-Body simulations of the globular cluster in our test potential.</p>

<h2>LARS and eLARS</h2>
<p>The Lyman Alpha Reference Sample (LARS) is a large Hubble project and international collaboration testing the escape of Lyman Alpha photons from distant galaxies.</p>
<p>LARS utilizes almost the entire electromagnetic spectrum: from UV and optical spectra that reveal intense star formation, to radio observations that probe the neutral hydrogen and molecular gas content. The survey started with 14 galaxies and 28 more have now been added through e(xtended)LARS. We have conducted HI observations using the GBT, VLA, and GMRT of all 14 LARS galaxies and many of the 28 eLARS.</p>
<p>I recently published a <a href="http://arxiv.org/abs/1408.6275">paper</a> detailing the reduction and analysis of these first 14 galaxies.</p>
