Biography

Dr. Carrano is a Principal Scientist at Boston College’s Institute for Scientific Research (ISR).  His contributions have been in the areas of ionospheric impacts on radar, satellite communications, and the Global Navigation Satellite Systems (GNSS). He has served as Principal Investigator for a number of projects including the propagation of HF waves through a structured ionosphere, and high-fidelity simulation of scintillation and its impact on dual-frequency GPS receivers. He introduced and taught GE 195, the first course on Space Weather for undergraduate students at Boston College. He has been an Associate Editor of the American Geophysical Union (AGU) journal Radio Science, and has served on the Editorial Board of the quarterly journal GPS Solutions. He is a member of the AGU, the Union Radio-Scientifique Internationale (URSI), and the Institute of Navigation (ION).

Before joining the ISR, Dr. Carrano managed the Ionospheric Environments and Impacts group of the Space Weather and Effects Division at Atmospheric and Environmental Research, Inc. (AER). There he served as Principal Investigator for an SBIR related to real-time specification of the near-Earth space environment and as Co-Investigator for a BAA involving data fusion techniques for ionospheric monitoring. He has also served as AER project leader for the AFRL SCintillation Network Decision Aid (SCINDA), a real-time global network for ionospheric scintillation specification and forecasting. Dr. Carrano has developed systems for real-time monitoring of the ionosphere that are deployed in networks spanning the globe including the AFRL-SCINDA network, the Low-latitude Ionospheric Sensor Network (LISN), the Canadian High Arctic Ionospheric Network (CHAIN), and the Instituto Nacional de Pesquisas Espaciais (INPE). He has managed the development of operational space weather products at Air Force Weather Agency (AFWA), Space Environment Technologies Application Division (SMC/WXT), and the Defense Modeling and Simulation Office (DMSO).

Dr. Carrano earned his Ph.D. in aerospace engineering at The Pennsylvania State University and his B.S. in mechanical engineering at Cornell University. At PennState he taught advanced mathematics for engineers. He has published a number of journal articles, and presented papers and tutorials at numerous domestic and international scientific meetings. He has been granted five Scientific and Technical Achievement Team Awards by the Air Force Research Laboratory's Space Weather Center of Excellence, been granted awards by the Institute for Scientific Research for Outstanding Achievement and Scientific Excellence, and been named Employee of the Year by Atmospheric and Environmental Research, Inc.
