Professor Agüeros received his B.A. in Astronomy from Columbia University
before earning an M.Phil in Physics from the University of Cambridge (UK)
and his Ph.D. in Astronomy from the University of Washington. Before joining
the Columbia faculty, he was a National Science Foundation Astronomy and
Astrophysics Postdoctoral Fellow in the Columbia Astrophysics Laboratory for
four years. For two of those years, he was also the Associate Director of
Columbia's Bridge to the Ph.D. Program in the Natural Sciences, which he now

Professor Agüeros's interest lies in using new datasets and technologies to
address classic questions in stellar astrophysics. One example is his work
using Palomar Transient Factory data to obtain rotational periods for
low-mass stars. This is part of an open cluster survey he is leading to
calibrate the relationship between stellar age, rotation, and magnetic
activity. The existence of such a relationship was established over 40 years
ago in solar-mass stars, but its exact form and theoretical underpinnings
remain unknown. This has implications for stellar evolution and for
observationally determining the ages of field stars. Professor Agüeros's
webpage describes his research interests, and the work of his students, in
greater detail.
