Extension: (Streatham) 5522Overview:
I'm an experimental astrophysicist interested in high contrast imaging and spectroscopy of exoplanetary systems. Specifically, for my PhD at Columbia University, and while a Sagan and an NSF Fellow at the California Institute of Technology, I led the development of an infrared imaging spectrometer for Palomar Observatory dedicated for this task. Since my arrival at Exeter, I have become an active user of ESO facilities, while continuing to mine through my large direct imaging survey for planets I carried out at the W. M. Keck Observatory while at Caltech. I am also the Principal Investigator for an approved 54-hour Early Release Science Program with the James Webb Space Telescope, working with Andy Skemer (UCSC) and Beth Biller (Edinburgh) as well as numerous other astronomers across the world.
- My first PhD student Elisabeth Matthews, now a postdoc at MIT, led our survey for planets around young stars with evidence for multiple belts of circumstellar debris using SPHERE at the VLT. Elisabeth's work uncovered a spectacular image of a nearly edge-on disk around the star HD 129590 (see paper below).
- My current PhD student Aarynn Carter, jointly advised by David Sing, works on both Transit Transmission Spectroscopy using HST, as well as High Contrast imaging with JWST.
