Essam Heggy (Egyptian Arabic: عصام حجى‎, pronounced [ʕeˈsˤɑːm ˈħeɡɡi]) is an American space scientist from French and Egyptian origins. Heggy obtained his Ph.D. in astronomy and planetary science in 2002 with distinguished honors from the Sorbonne University in Paris. His main science interests in space and planetary geophysics covers Mars, the Moon, icy satellites and near-Earth objects. His research involves probing structural, hydrological and volcanic elements in terrestrial and planetary environments using different types of radar imaging and sounding techniques as well as measuring the electromagnetic properties of rocks in the radar frequency range. His research expertise span from laboratory electromagnetic characterization of planetary analog materials, Radar sounding of aquifers in hyper-arid environments, GPR surveys in volcanic and ice-rich environments, FDTD numerical simulations of wave propagation and terrestrial and planetary radars data analysis. Heggy is a member of the science teams of several planetary exploration missions, and he is a contributing scientist to several proposed planetary and terrestrial radar imaging and sounding experiments. Heggy taught academic classes and mentored several postdocs and graduated students in UCLA, Caltech, Cambridge University, Paris VI & Paris VII universities, Institut de Physique du Globe, Ecole Normale Superieure, University of Houston, Trento University and Columbia University.
