THE WORK TO BE PERFORMED AT THE GEORGE MASON UNIVERSITY WILL CONSIST IN THE ANALYSIS OF REMOTE-SENSING OBSERVATIONS OF CORONAL SHOCKS ASSOCIATED WITH THE ORIGIN OF SOLAR ENERGETIC PARTICLE (SEP) EVENTS. EXTREME-ULTRAVIOLET (EUV) AND WHITE-LIGHT (WL) IMAGES COLLECTED FROM INSTRUMENTS ON SOHO SOLAR DYNAMICS OBSERVATORY (SDO) STEREO-A AND STEREO-B WILL BE COMBINED TO RECONSTRUCT THE 3D LARGE-SCALE STRUCTURE OF CORONAL SHOCKS. A CODE DEVELOPED AT GMU WILL BE USED TO MODEL THE TIME EVOLUTION OF CME SHOCKS SO THAT THE SHOCK SURFACE AND SHOCK SPEED CAN BE DETERMINED GLOBALLY. THIS MODEL HAS BEEN SUCCESSFULLY APPLIED TO AN AMPLE NUMBER OF EVENTS AND SEVERAL AUTHORS HAVE ADOPTED IT TO DESCRIBE THE STRUCTURE AND EVOLUTION OF CORONAL SHOCKS IN SPECIFIC SEP EVENTS. THE TASK WILL CONSIST IN THE APPLICATION OF THIS MODEL TO A LARGE NUMBER OF EVENTS. THE PROPOSED RESEARCH WILL BE DEVELOPED IN THE FRAME WORK OF THE FOCUSED SCIENCE TOPIC (FST) "TOWARD A SYSTEMS APPROACH TO ENERGETIC PARTICLE ACCELERATION AND TRANSPORT ON THE SUN AND IN THE HELIOSPHERE" OF THE NASA LIVING WITH A STAR PROGRAM. IN ORDER TO PROGRESS IN THIS TOPIC A DEEP KNOWLEDGE OF THE ROLE THAT CORONAL SHOCKS PLAY IN THE ACCELERATION AND INJECTION OFSEPS ONTO DIFFERENT REGIONS OF INTERPLANETARY SPACE IS REQUIRED.
