BIOGRAPHICAL SKETCH

Dr. Saganti is currently a NASA Research Faculty with the NASA Center for Applied Radiation Research and an Associate Professor in the Department of Physics at the Prairie View A&M University, Prairie View, TX. He currently serves as PI on two NASA Grants – MARIE (Martian Radiation Environment Experiment), RaISE (Radiation Inter university Science and Engineering), and as a PI on NASA Co-op Agreement – QMSFRG (Quantum Multiple Scattering and Fragmentation). Dr. Saganti has been working with the GCR radiation environment modeling at Mars and of the near earth orbit including the GCR modulation studies under the mentorship of Dr. Cucinotta. Contributions in the expansion of the GCR environment and HZETRN model calculated predictions of dose rate at Mars showed a significant correlation of within 5% with the MARIE measured data. Model calculated GCR environment and transport calculations were presented at several national and international conferences world-wide. Some of the visualization of radiation environment work appeared in several NASA publications and NASA websites as well as National Geographic, DISCOVER, and SCIENCE journals.

For more than 15 years, Dr. Saganti contributed to the NASA’s Exploration Vision through Image Science Analysis Group at NASA-JSC supporting more than 30 Space Shuttle missions including Hubble Space Telescope repair missions, MIR and ISS. Most recently he also served on the Space Shuttle Columbia accident as part of the image analysis investigation team on a special assignment for developing image analysis techniques required for the NASA investigation.

Dr. Saganti also received 15 years ‘State of Texas Service Award’ recognition in 2006 from President Wright of the Prairie View A&M University for serving the University of Houston and the Texas A&M University Systems.
