Our Research


The Remote Sensing for Space Sciences group in the Department of Physics and Astronomy at Georgia State University conducts research that is focused on two branches of the field of remote sensing:

Typically the techniques and instrumentation we develop in one branch have application in the other.

Our group is also a member of GSU’s Imaging Hub which is a part of GSU’s Imaging for Global Solutions Intiative.. The Imaging Hub is a consortium of faculty, postdocs and students from the Departments of Physics and Astronomy, Chemistry, Mathematics and Statistics, Psychology, Computer Science and Biology who involved in cutting-edge Imaging research.

Students working with our group have the opportunity to participate in a cross-disciplinary team with strong ties to researchers inside and outside of the academic world, both here in the USA and internationally. In addition, students working with our group  have the opportunity to participate in a dual Ph.D. program with the University of Rome, Italy (Ph.D. in Astronomy from Georgia State University and a Ph.D. in Astronomy, Astrophysics and Space Science from the University of Rome).

Research Group

We design, build, and field instruments. We also conduct  numerical simulations and develop custom algorithms for data reduction and analysis.

Optics Laboratory

We are developing an optics laboratory for rapid prototyping and testing of instruments that have been developed and validated using numerical simulations. Once the performance of an instrument has been practically validated, the laboratory also serves as a testing and calibration facility for the field version of the instrument.

Our group has received two awards from the Department of Defense DURIP program to build an advanced atmospheric simulator and testbed for the validation of novel methods for high-resolution imaging through atmospheric turbulence (ARES: a simulator for the Advanced Reconnaissance of Earth-orbiting Satellites).

Our group participates in a number of close collaborations with other  research groups here in the USA and in Europe.  These interactions offer a number of opportunities for students including cross-disciplinary research, exposure to the different research environments in academia, national laboratories,  government and private business, summer internships, and international exchanges.
