Ph.D. Thesis: High-Contrast Observations with an Integral Field Spectrograph • Confirmed the physical association of Alcor's M-dwarf companion through a novel relative astrometry technique. • Designed and implemented the data extraction and calibration software for Project 1640, a coronagraphic integral field spectrograph. • Carried out the first combined aperture mask + integral field spectrograph observation. Practical Skills • Observation: natural guide star adaptive optics, integral field spectroscopy, coronagraphy, and aperture mask interferometry with Project 1640 at the Hale Telescope; infrared angular differential imaging with LMIRCam on the LBT; narrow-angle astrometry with the PRIMA facility at the ESO VLT Interferom- eter; aperture synthesis radio imaging with the NRAO VLA; conventional optical imaging and long-slit spectroscopy. • Instrumentation and engineering: High-contrast imaging data processing and starlight subtraction algo- rithms; deformable mirror control; optical surface figure measurements via pupil-shearing interferometry; ray trace and Fresnel propogation simulations; optimization with genetic algorithms; antenna simulation and testing; water Chereknov cosmic ray detection; analog and digital circuit design and testing. • Programming: Python, Matlab, C, IDL, Perl.
