### Professional Leadership

Director, Coordinated Engineering and Engineering Honors Program, 1988-present. The program constitutes the first two years of the baccalaureate degree awarded in the fields of chemical, civil, computer, electrical, environmental and mechanical engineering. A carefully articulated coordination with the engineering schools of Polytechnic University, City College and the College of Staten Island guarantees transfer to these institutions into the junior year. (Students also transferred to MIT, SUNY Stony Brook, University of Wisconsin, Cooper Union, Michigan State University, Purdue University and the University of California). In 2002, the engineering program was incorporated into the Honors Academy of Brooklyn College as the Engineering Honors Program. My responsibilities include orientation, advising, recruitment, open houses, financial aid and transfer officers to meet with our students, and to renegotiate the articulation as changes in engineering education occur. *(Professional Leadership: Committee Service)* 2008
