Bulent Kiziltan Harvard LogoMy research focuses on compact objects; mainly neutron stars, pulsars, supernova remnants and related phenomena. I am also interested in the evolution of white dwarfs, stellar-mass black holes; the formation,   evolution and dynamics of globular clusters

I use multi-wavelength data to probe diverse aspects of stellar and cluster evolution. I also use Bayesian statistical methods in conjunction with stellar population synthesis modules to constrain bulk properties of stellar populations.

Recently, I have gotten interested in developing time-series analysis techniques, particularly tailored for detecting very faint periodic fluctuations in astronomical data which are applicable to a wide range of astronomical problems.
