Postdoctoral Associates & Fellows
Tabetha Boyajian
Tabetha recently finished a Hubble Fellowship at Georgia State University where she worked on direct measuremnt of stellar diameters using interferometry. She is a now a Postdoc in Fischer's exoplanet group at Yale, where she is continuing her work on stellar astrophysics and is now working with Planet Hunters to study binary stars and planets in the Kepler data.

Tyler McCracken
Tyler earned his Ph.D.from New Mexico Tech where he worked fringe-tracking for the interferometer at Magedelena Ridge Observatory. He is now a postdoc in Fischer's exoplanet group at Yale, developing a wavelength calibration technique based on a Fabry-Perot cavity locked to a stabilized laser. This approach offers advantages over other methods: it produces a broadband, comb-like output from 400 - 700 nm that is difficult to achieve with a laser frequency comb; by injecting into the science fibers before and after observations, weak stellar signals are not obliterated; and by locking the laser to an atomic transition, the spectrum is repeatable to 1 part in 10e-11.
Rebecca Stoll
Rebecca earned her Ph.D. from The Ohio State University where she worked on building and commissioning instruments for the Large Binocular Telescope, MDM Observatory, and the Mayall and Blanco telescopes. She is now a postdoctoral fellow in the Yale Exoplanet Lab and is improving the R=150,000 bench-mounted spectrograph in the lab and designing the atmospheric dispersion corrector for the Moletai Observatory spectrometer.
Ji Wang
Ji is a Postdoctoral Associate in Debra Fischer's exoplanet group at Yale.
He is analyzing Kepler data with help from Planet Hunters. He is also working to understand the occurrence rate of planets in binary and multiple star systems. His other interest is instrumentation and he is contributing to novel wavelength calibration sources for extreme precision exoplanet searches. Ji is also managing the Doppler code group in the Lab, working with applied mathematicians and our team to develop an optimized C++ version of the code.
