-Characterizing formation mechanisms of planetary host stars.

-Identification of molecular abundances in star forming regions and protoplanetary disks.

Research Experience

02/2015-Present Lowell Observatory Research Assistantship; Flagstaff, AZCharacterization of Young Binaries-We are utilizing photometric and spectroscopic observations of young binary stars in order to determine thephysical properties of over one hundred systems. These results will assist our understanding of formationmechanisms of binary systems in addition to their likelihood to host exoplanetary bodies.

09/2014-12/2014 Gemini North Internship; Hilo, HIAccretion Disk and Dust Emission Mechanisms of Low-Luminosity AGN-Using GNIRS (Gemini Near-IR Spectrograph) cross-dispersed galaxy spectra, we test a method in which wedisentangle the AGN emission from the stellar emission in the host galaxies in order to test whether their accre-tion disk becomes truncated at low accretion rates and their inner region replaced by an advection-dominatedaccretion flow. We also use our analysis to identify whether the obscuring torus of the AGN unified modeldisappears at low accretion rates.

08/2012-07/2014 Exoplanet Characterization-Characterization of transiting exoplanets by utilizing photometry from ground based observations; primarilyatmospheric characterization, magnetic field detection, and amending planetary parameters and ephemeris aswell as stellar parameters.

09/2013-05/2014 Deuterium Abundances in Molecular Cloud Cores-Carry out the first astrochemical survey that compares deuteration rates in the complete core population withina single molecular cloud. Approximately 120 cores in Perseus were observed in the lines of N2D+ 3-2, DCN3-2, DNC 3-2, DCO+ 3-2, and NH2D 1-1 using the HHT and the IRAM 30m Telescope.

08/2012-05/2014 Stellar Characterization of Kepler Targets-Perform data acquisition using the Kuiper 1.55m/Mont 4K for Dr. Elizabeth Green.-Determine stellar cycle and rotational period as a function of spectral type by identifying patterns in thevariation in brightness of a large sample of Kepler targets.

06/2013-08/2013 REU in Solar and Space Physics; SwRI Boulder, CO-Develop SMEI (Solar Mass Ejection Imager) code to adapt to the HI (Heliospheric Imager) data on boardSTEREO Spacecraft to develop a CME database from the data archives. Work toward developing an integratedtool for space weather prediction.

08/2012-05/2013 Star Formation Signatures in Molecular Cloud Cores-We observed cold cores in the Perseus molecular cloud in search of asymmetry in the observed spectral linesas a sign of infall. Observations were taken using the 12-meter Radio Telescope atop Kitt Peak, Arizona.
