recieved his BSc and MSc in mathematical science from
University College Dublin in 1987 and 1988,
and his PhD in theoretical physics from Caltech in 1993, where he studied with Kip Thorne.
He was then a postdoctoral fellow at Caltech for one year, and from
1994 to 1996 was an
Enrico Fermi fellow
at the University of Chicago.
In August 1996 Flanagan
joined the faculty of the Astronomy and Physics
departments at Cornell University.
He was awarded an Alfred P. Sloan Foundation
Fellowship and a National Science Foundation
in 1997. He was elected to a three year term on the executive committee of
the American Physical Society Topical Group in
Gravitation in 1999 and again in 2004. In 2002 he was awarded a
by the Radcliffe Institute for Advanced Study at
Harvard University, where he spent the 2002/03 academic year.
In 2004 he was awarded the
Basilis C. Xanthopoulos International Award
for Research in Gravitational Physics.
In 2007 he was elected a fellow of the American Physical Society.
In 2013 he became a fellow of the International Society of General Relativity and Gravitation.
My research interests include general relativity, relativistic
astrophysics, cosmology, and quantum fields in curved spacetime.
Currently, one focus of my group's research is understanding various sources
of gravitational radiation, and developing analytical approximation methods to
calculate the gravitational waves they emit. Gravitational waves have recently
been detected by
LIGO (the Laser
Interferometer Gravitational Wave Observatory). Another focus
is exploring string-theory inspired models of the Universe with
extra-dimensions and branes, and their implications for cosmology and
