Biography:

Dr. Priscilla N. Mohammed received a Ph.D. in Electrical Engineering (2005) and a Masters Degree in Electrical Engineering (2001) both from the Georgia Institute of Technology, Atlanta GA, and a BS in Electrical Engineering (1999) from the Florida Institute of Technology, Melbourne, FL. As a Ph.D. student, she performed microwave measurements of gaseous phosphine and ammonia under simulated conditions for the outer planets and used these measurements to develop a radio occultation simulator to predict absorption and excess Doppler due to Saturn's atmosphere. Much of this work was in support of the Cassini mission to Saturn. Based on these laboratory results, the Cassini Project Science Group made the decision to extend the Ka-band (32 GHz) operation throughout the mission tour. The predicted attenuation profiles for the Cassini radio occultation maneuver of May 2005 earned her an invitation by the Cassini Radio Science Team to present a paper on their behalf at the 37th Annual Meeting of the Division for Planetary Sciences in Cambridge, England. In 2006 she joined the Goddard Earth Sciences and Technology Center at the University of Maryland, Baltimore County, as a member of their research faculty. Her current research interests include radio frequency interference mitigation in microwave radiometers.
