Andreas Zezas
(Harvard-Smithsonian Center for Astrophysics)
Andreas comes from Athens, Greece. Since his junior
high-school
years he was keen to understand why our Cosmos is
the way it is. This
interest naturaly led him to become an Astronomer.
He received his degree in Physics from the University
of Patras (Greece),
and then moved to Leicester (UK) to pursue his PhD,
under the
supervision of Martin Ward. He finished his PhD
just in time to work
with some of the very first detailed images of the
X-ray sky, obtained
with the Chandra X-ray observatory. Since 2000,
he has been an
Astrophysicist in the High-Energy Astrophysics Division
of the CfA, at
the sunnier, but colder Cambridge (USA).
His initial work was on the X-ray properties of
other galaxies, and particularly their populations
of X-ray binaries (black-hole and neutron star binaries).
More recently he has been drifting away to lower
energies, and has been using ground based telescopes,
as well as the Hubble Space Telescope and the Spitzer
Space Telescope, to study the star-formation processes
in nearby galaxies and how they relate to the X-ray
binary populations.
Other members of Dr. Zezas's science team include
K. Gazeas (bio below), G. Fabbiano, A. Prestwich,
and M. Garcia (Harvard-Smithsonian Center for Astrophysics),
J. Gallagher (University of Wisconsin, Madison),
J. Miller (University of Michigan), P. Kaaret (University
of Iowa), V. Kalogera (Northwestern University),
M. Ward (University of Durham), and A. King (University
of Leicester).

Kosmas Gazeas
(Harvard-Smithsonian Center for Astrophysics)
Kosmas Gazeas received his Masters of Science
and PhD in Astrophysics at the University of Athens
in Greece. He is currently a postdoc at the Harvard-Smithsonian
Center for Astrophysics.
The project he is working on deals with the analysis
and interpretation of HST/ACS data of the prototypical
spiral galaxy M81. His study focuses in the derivation
of a spatially resolved star-formation history and
its connection with the galaxy's X-ray source populations,
in order to understand the formation and evolution
of X-ray binaries.
Other research interests include studies of close
binary stars, pulsating and cataclysmic variables,
asteroseismology and extrasolar planets. Instrumentation
is also one of his favorite topics. During his PhD
research he contributed in the field of stellar
evolution of contact binaries, by studying the correlations
between their physical parameters.
Aside from astronomy, Kosmas' interests include
trekking, caving and photography.

John Huchra
(Harvard-Smithsonian Center for Astrophysics)
John Huchra was educated at the Massachusetts Institute
of Technology and the California Institute of Technology.
He obtained his PhD from Caltech in 1976. He is
currently the Senior Advisor to the Provost for
Research Policy and a Professor of Astronomy at
Harvard University and on staff at the Harvard-Smithsonian
Center for Astrophysics.
His research interests include the study the Large-Scale
Structure in the Universe, the general study of
Observational Cosmology including the determination
of the expansion rate, age and fate of the Universe,
observations of Active Galactic Nuclei (AGN), and
galactic evolution, particularly star formation
in galaxies and globular star cluster systems surrounding
other galaxies. He has worked in many areas of astronomy,
and especially loves teaching and observing.
Other collaborators on the Hubble ACS data of M81
include P. Barmby, and B. Mcleod (Harvard-Smithsonian
Center for Astrophysics) and J. Brodie and J. Strader
(University of California, Santa Cruz).
