John Cartledge received the B.Sc. degree in mathematics and engineering in 1974 and the M.Sc. and Ph.D. degrees in mathematics in 1976 and 1979, respectively, from Queen's University, Kingston, Ontario, Canada.

In 1979 he joined Bell-Northern Research, Ottawa, as a Member of the Scientific Staff.  His work involved fiber-optic systems for the exchange access network and high-capacity digital radio systems. In 1982 he joined the Department of Electrical Engineering, Queen's University where his research has focused on optical fiber transmission systems. In 2017 he became Professor Emeritus with the Department of Electrical and Computer Engineering, continuing to conduct research and supervise graduate students. Dr. Cartledge has spent sabbatical leaves with Bellcore, Red Bank, NJ, in 1988-89, Tele Danmark Research, Hørsholm, Denmark, in 1995-96, Corning Inc., Corning, NY, in 2009-10, and Ciena, Ottawa, ON, in 2014 and 2017.

Dr. Cartledge is a Fellow of the Optical Society of America, a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), a former IEEE Photonics Society Distinguished Lecturer (2008-2010), and recipient of the IEEE Canada Outstanding Engineering Educator Award (2009). His conference organization activities include serving on the Technical Program Committees for the Conference on Optical Fiber Communication (1994-1997 and 2005-2006), the IEEE LEOS Annual Meeting (2002-2008), and the European Conference on Optical Communication (1997, 2006-2015). He was a Program Chair and General Chair for the Conference on Optical Fiber Communication (2008 and 2010, respectively), and a Program Chair for the IEEE Photonics Society Summer Topical Meeting (2009). He is a former Associate Editor for IEEE Photonics Technology Letters and a former Editor-In-Chief for IEEE Journal of Selected Topics in Quantum Electronics.

Topics currently being investigated include the following:

• digital signal processing for transmitters and receivers in coherent optical fiber transmission systems,
• techniques for assessing the implications of transmission impairments on system performance,
• signal processing algorithms for compensating transmission impairments, and
• spectrally efficient modulation formats including constellation shaping.
