I am a professor of astronomy at University of Massachusetts.
My research has been focused on galaxy formation, large-scale
structure of the universe, and cosmology. I construct models for the formation of disk galaxies,
the formation and structure of dark matter halos, the connection between galaxies and dark
matter halos, the structure of gaseous halos, and physical processes related to galaxy formation
and evolution. I use galaxies and galaxy systems from observations and from simulations
to understand the properties of dark matter halos and the distribution of dark matter in
the Universe, as well as to reconstruct the current and initial density fields
for the local Universe.
I have coauthored a text on `Galaxy formation and evolution' which was
published by Cambridge University Press. Please refer to my Reasearch and Publications for
the details of my research interests.
