Christi Madsen

Christi Kay Madsen is an American optical engineer. She is a professor in the Department of Electrical & Computer Engineering at Texas A&M University. Her research interests include optical filters, photonics, optical communication using wavelength-division multiplexing, and solar energy. She is particularly known for her development of coupled multiple ring resonator filters and multistage optical all-pass filters.

Education and career Madsen majored in electrical engineering at the University of Texas at Austin, graduating in 1986. She continued her studies in electrical engineering at Stanford University, where she received a master's degree in 1987, and at Rutgers University, where she completed her Ph.D. in 1996.

She was a distinguished member of the technical staff at Bell Labs and later Lucent Technologies before taking her present position at Texas A&M University in 2004. She is also the founder of a spinoff company from Texas A&M, Sunstrike Optics LLC.

Textbook Madsen is a coauthor of the textbook Optical Filter Design and Analysis: A Signal Processing Approach (with Jian H. Zhao, Wiley, 1999).

Recognition Madsen is a 2004 Optica Fellow, honored "for contributions to optical waveguide circuit design and implementation, especially tunable dispersion compensators for high capacity optical networking systems". She was named as a Fellow of SPIE in 2023, "for her technical achievements in the multidisciplinary fields of optics, photonics and imaging, and for her service to SPIE and the optics and photonics community".
