Summary:

Dr. Unwin received his BA and PhD degrees from the University of Cambridge, and was a

postdoctoral fellow and then a member of the Professional Staff at Caltech. At Caltech, Dr.

Unwin studied active galactic nuclei using VLBI and X-ray techniques, and for several years he

was manager of the VLBI correlator, an essential component of VLBI imaging, and he also

contributed to techniques for sparse-aperture imaging. He moved to JPL in 1996 to work on the

Space Interferometry Mission, and was Deputy Project Scientist for the project during its long

development. He has experience with observation and instrumentation at many telescopes and

spacecraft, including OVRO, Parkes, Palomar, CSO, VLA, VLBA, ROSAT, FERMI, and Kepler.

Dr. Unwin s current research interest is the detection and characterization of extrasolar planets and

the dust disks that trace the formation history of exoplanetary systems. He has extensive

experience in science requirements management and implementation in space instruments, and in

end-to-end mission concept development. He has worked extensively with community-based

science teams in his role in NASA s Exoplanet Exploration Program. He has been a co-I on

several astrophysics mission proposals, and has led several proposal development teams.

Conferences:

I have chaired numerous workshops, working group meetings, and conferences, in addition to

convening, organizing, and setting the agendas for more than 25 mission (SIM) science team

meetings. I served as the principal organizer for several conferences:

NASA Astrophysics Mission Concepts Studies Pre-Proposal Workshop, Pasadena, 2007

AAS Division on Dynamical Astronomy Annual Meeting, Halifax, Canada, June 2006

(Program Chair, responsible for the scientific program; I also served as Chair of the Division)

Dust Disks and the Formation and Evolution of Habitable Planets, San Diego, 2004 (LOC

Chair; and edited online proceedings)

Working on the Fringe, Dana Point 1999 (LOC Chair; and edited hardcopy conference

publication for Proceedings of ASP)

Research publications:

In addition to the above responsibilities, I have maintained an active astronomical research

program, with over 35 papers published in refereed scientific journals since 1978. The following
