Research Members


Over the years, Dr. Lehman has helped the education and supervision of many accomplished research graduate students that have gone on to illustrious careers. His students have won and continue to receive multiple awards for their teaching and research, both at Northeastern University and within IEEE. In his approximately 20 years in academics, Dr. Lehman has supervised / currently supervises approximately 30 graduate research thesis/projects, over half of which are for the PhD. He places special emphasis on recruiting cultural diversity, as well as female graduate students. Funded students tend to have an MS degree already and likely have some industry experience working in the power supply industry with PCB layout experience. In addition to the graduate students, Dr. Lehman has a special interest/program in working with under-represented minority undergraduate students on research projects.
