Biographical Sketch: 

Priya Natarajan is a theoretical astrophysicist interested in cosmology, gravitational lensing and black hole physics. Specific questions that her work addresses are:


  • Substructure in cosmological models
  • Evolution and assembly of clusters
  • Cosmological constraints from clusters and lens statistics
  • Gamma-ray bursts as cosmological probes
  • Mapping dark matter
  • Probing the nature of dark energy with cluster strong lensing
  • Black Hole seed formation at high redshifts
  • Mass assembly history of black holes
  • Alignments of black hole spins
  • Black hole accretion
  • Warped accretion disks
  • High redshift pre-galactic disks
  • Direct formation of black hole seeds
  • Feedback processes: energy input from AGN and Supernovae
  • Issues in epistemology
  • Philosophy of Cosmology
