The Climate and Radiation Laboratory at NASA Goddard Space Flight Center (GSFC) seeks a scientist with expertise in shortwave polarized radiative transfer for Earth science applications, and in particular the remote sensing of clouds and aerosols. The scientist will be conducting research which includes, but is not limited to, assessing, enhancing and improving the algorithms and techniques used for the remote sensing of aerosol and cloud properties from satellite, airborne, and ground instruments; studying the polarized radiative signals at solar wavelengths of atmospheric particles and various surfaces; creating simulation tools that mimic the measurements of instruments observing such polarized radiative signals, including versions that can be implemented in atmospheric models.

Dear Colleagues,


I am planning to hire a postdoc through my recently funded NSF CAREER grant. The position will primarily focus on light scattering simulations, but will also include evanescent wave scattering and (potentially) holographic microscopy experiments, of complex colloidal particles (ellipsoids, Janus particles, cells). I have allocated 2-years of funding for the position, so the 1-year contract will be renewable.


The individual will initially spend a few weeks at the beginning of the postdoc with my collaborator, Thomas Wriedt, at the Institute of Powder and

Particle Measurement in Bremen, Germany to learn about the T-Matrix method and how to run the simulations, which are described in a forthcoming paper in the Journal of Modern Optics. We are using these simulations to compare with experiments run in my lab of scattering from ellipsoidal and composite (i.e. Janus) particles.


Note that our group recently moved into a new facility, a combined Soft Materials and Complex Fluids Lab at CSU. This facility, along with our neighbors CWRU, Akron, Kent State, and NASA Glenn, make NE Ohio a great place for complex fluids, colloids, and soft matter research! I have found colleagues at these neighboring institutions to be collegial and welcoming.


The official advertisement should be available in a few weeks. However, please feel free to let your students and colleagues know about this opportunity. Given the importance of this project, the individual will have a substantial opportunity to be productive during her/his postdoc.
