My research interests are in the structure and formation of cluster-sized dark matter halos in the ΛCDM cosmological framework. More specifically, I am interested in understanding how theory and observations of these clusters differ due to intrinsic properties of the halo. I primarily study clusters using gravitational lensing as a tool for mass reconstruction.

I am the primary author of the CosmoSim package within the Astroquery module (an Astropy affiliated project), which provides tools for querying various observational and simulation databases within the field of astronomy and astrophysics. The CosmoSim database is home to six cosmological simulations of structure formation. This module was designed with a particular idea in mind: that there should be little to no barrier to entry in obtaining large amounts of data for conducting scientific research.

About Me

Originally a native of New Marlborough, Massachusetts located in the Berkshire Mountains, I attended Mt. Everett Regional Highschool. I hold a B.A. magna cum laude in Physics with minors in Mathematics and Geology from Hartwick College. At Hartwick I was able to incorporate a considerable amount of traveling into my curriculum, traveling to Ghana, The Bahamas, and Hawaii. In my free time I volunteered at a local fire department where I became a New York State certified interior and exterior fire fighter. I later went on to obtain an M.S. in Physics from Drexel University in Philadelphia, Pennsylvania. Since my move to Philadelphia I have developed a great interest in teaching - especially in the Contemporary Physics track for freshmen physics majors. This series of courses combined traditional freshmen physics material with added topics like quantum mechanics, relativity, and a scientific python programming component. Recently, I have begun spending free time developing open-source software for astrophysicists. Other hobbies of mine include soccer, biking, skiing, reading, and playing the trumpet and piano.
