Output from my current simulations described in Current Work


Current Work

My current research is focused on modeling weak gravitational lensing. This research is still in progress. My ultimate goal is to write a full parallel-computing simulation capable of running on GPUs which models weak gravitational lensing in the universe. This will be used to probe fundamental questions about weak lensing theory and understanding such as the validity of certain weak lensing assumptions and the roles of dark matter halos in weak lensing. The images to the left are outputs of my simulations thus far. The top image shows ~2000 galaxies in the sky from the Sloan Digital Sky Survey and the dark matter surface mass density in the field of view due to the galaxies. The bottom image represents the lensing affect they would have on background galaxies. In effect, it represents how much the image of background galaxies would be distorted due to the foreground galaxies. The results of this simulation have been presented as a poster at the 225th American Astronomical Meeting where it won the Chambliss Astronomy Achievement Student Award. For more information, the poster can be viewed here.

Past Work

In the past I have been part of several research groups. My most recent work was with Dr. Dimitri Sverjenksy as part of the Deep Carbon Observatory (DCO). I developed a program to calculate deep earth geochemical thermodynamic properties. To read more or download the program, visit the DCO's website.

I have worked with Dr. Theodore Fritz as part of the Center for Space Physics at Boston University. My work focused on writing programs to analyze ISEE satellite data to study particle flows in the Earths magnetosphere.

As an undergraduate I worked with Dr. Alan Marscher and Dr. Svetlana Jorstad as part of the Blazar Group at the Institute for Astrophysical Research. My work involved calibrating science images of blazars from the VLBI and tracking knots of ejected plasma.
