His research interests are in the broad area of applied electromagnetics and more specifically in microstrip and dielectric resonator antennas. His most recent work has been focused on broadband dielectric resonator antennas and on the use of existing structures to serve as radiators for wireless communications systems. Over the past several years Dr. Long has also begun a program designed to increase the number of graduates in engineering. Among these are GRADE Camps which bring high school girls to campus during the summer, the RET program which allows high school teachers to be involved in research, the REU program which involves undergraduates in research activities, the WIE-UH program which forms a community for female engineering students, and Redshirt Camps that aid in the retention of currently enrolled students. These programs are sponsored by NSF and the State of Texas.
