Curriculum Vitae:

James Sinclair

  • MPhys., in Astrophysics, University of St. Andrews, United Kingdom (2010)
  • DPhil., in Atmospheric, Oceanic & Planetary Physics, University of Oxford (2014)

Research Interests
  • Remote sensing of planetary atmospheres
  • Infrared astronomy
  • Evolution of planetary atmospheric structure/composition
  • Giant planets


Cassini-Huygens Icon Cassini-Huygens
The Cassini-Huygens spacecraft is currently exploring the ringed planet, its mysterious moons, the stunning rings and its complex magnetic environment.

Juno Icon Juno
Juno will fly to Jupiter and orbit its polar regions in order to understand the planet's gross size and structural properties, as well as measure Jupiter's atmospheric composition, temperature and deep wind profiles.

Professional Experience
  • NASA Postdoctoral Fellow, Jet Propulsion Laboratory (2015 – present)
  • Postdoctoral Research Assistant, University of Oxford (2014-2015)
  • DPhil Student, University of Oxford (2010 – 2014)
  • Summer Internship Research Student, UK Met Office (2009)
