Dr. Lingze Duan, associate professor of physics at The University of Alabama in Huntsville (UAH), has been named a senior member of the Institute of Electrical and Electronic Engineers (IEEE). Dr. Duan's current research focuses on ultrafast optics, optical metrology and metrological instrumentation, fiber optics, and nanophotonics. Senior member is the highest IEEE professional grade for which members may apply. Only 7 percent of IEEE's 431,000 worldwide members have achieved senior membership. Senior membership is recognition of professional maturity and sustained achievements. It requires at least 10 years of membership and a demonstrated significant performance over at least five years of professional practice. "Typically, by the time a member is eligible for the senior membership, he or shemost likely has already played key roles in IEEE-designated fields or in the IEEE organization," says Dr. Duan. "In my particular case, I have been a regular reviewer for several IEEE journals for more than 10 years, I contribute papers to IEEE published journals and IEEE organized conferences, and I also participate in activities organized by the IEEE Huntsville Section."
