My research interests include star formation, circumstellar disks, and exoplanet detection and formation.

My Ph.D thesis, under the advisement of Dr. Joel Kastner (RIT), involves studying the circumstellar disks around nearby young  stars. Using multiwavelength data from both ground and space based telescopes, we are  determining the contents and structure of the gas and dust in these disks. By studying the composition of planet forming regions around other stars, we can learn more about the formation of our own solar system and how Earth obtained the necessary molecules for life to thrive.

I am also working on a project with fellow gradute student Billy Vazquez that involves searching for transiting exoplanets and stellar variability in the open cluster M103 (right). We have been imaging M103 since October, 2011 at the Vazquez Astronomical Observatory (VAO) in Webster, NY with a 12inch Schmidt-Cassegrain telescope. We are in the process of cataloging all stellar variability in the region, and using Stromgren photometry to approximate the spectra type of sources in the region. Follow-up work is being conducted at the WIYN 0.9m at Kitt Peak in Arizona.

In December of 2012, fellow graduate students Billy Vazquez, Marcus Freeman and I were awarded a grant to purchase an LHIRES III spectrograph, which will be mounted on the telescope at the VAO, and also use at the RIT observatory. With this instrument, and the assistance of Dr. Michael Richmond (RIT), we are determining the spectral type of many stars in M103, and also measuring the lithium abundances of nearby young stars to determine their age.
