Some of the African-American graduates of my lab have gone on to hold distinguished positions in academia and business, notably Anthony Johnson (professor of physics and director of CASPR at UMBC), Peter Delfyett (di- rector of the Ultrafast Photonics Group at CREOL), Ardie Walser (Associate Dean of Undergraduate Affairs at the Grove School of Engineering at CCNY), and Jean Dolne (Technical Fellow at Boeing). My women students have passion for science, and work extraordinarily hard with enthusiasm—which I call “the big E.” Women PhD graduates who have made marks in academia include Asima Pradham, professor of physics at the Indian Institute of Technology in Kampur, India.
