He was the Scifres Family Distinguished Professor of Electrical and Computer Engineering at Purdue University.
In 1992, Weiner was appointed at professor rank at the School of Electrical and Computer Engineering at Purdue University.
He is most well-known for research on the development of Fourier synthesis methods for controlling the shape of femtosecond light pulses.
[18] In 2008, Weiner was elected to the U.S. National Academy of Engineering, “for contributions to the development of femtosecond optical-pulse shaping technology.”[19] He is a Fellow of the National Academy of Inventors (2016),[20] the Optical Society of America (1990)[21] and the Institute of Electrical and Electronics Engineers (IEEE) (1995).
[24] He has received the Optical Society of America’s Adolph Lomb Medal (1990) in recognition of his early career achievements,[25] the International Commission for Optics Prize (1997),[26] the Alexander von Humboldt Foundation Research Award for Senior U.S. Scientists (2000),[27] the IEEE Photonics Society’s Quantum Electronics Award (2011),[28] and Optica's Charles Hard Townes Medal (2023).
