Curriculum Vitae:

Heidar Thor Thrastarson

Dr. Thrastarson was born and raised in Iceland, where he got his first Physics degree and thereafter worked in radiation physics at the Icelandic National Hospital. He furthered his education in Uppsala, Sweden, where he specialized in astrophysics and then got his PhD in London, where he started working on modelling of planetary atmospheres and, in particular, extrasolar planets. He came to JPL as a NASA Postdoctoral fellow in November 2011 and is currently a JIFRESSE researcher. His work at JPL has focused on planetary atmospheres, ranging from extrasolar planets to the Earth, using both Climate Models and satellite data. 


Education
  • PhD, Astrophysics, Queen Mary University of London, UK (2011)
  • MSc, Physics, Uppsala University, Sweden (2007)
  • BSc, Physics, University of Iceland (2003)

Research Interests
  • Dynamics and physics of planetary atmospheres, including boundary layers, clouds and convection, wave-flow interaction, large scale variability, thermodynamic structure and comparative climatology
  • Physical and numerical aspects of General Circulation Modeling and radiative-convective modeling
  • Observational atmospheric data analysis and application, including satellite radio occultations and infrared sounding
  • Climate and health applications, using climate data in epidemiological models for diseases
  • Characterization of extrasolar planets
  • Astrophysical fluid dynamics
