Adolfo Cartaxo was born in Montemor-o-Novo, Portugal, 1962. He received the degree of “Licenciatura” in Electrical and Computer Engineering, the M. Sc. degree in Telecommunications and Computers, and the Ph. D. degree in Electrical and Computer Engineering in 1985, 1989 and 1992, respectively, from Instituto Superior Técnico (IST), faculty of engineering of Lisbon Technical University. His Ph. D. research work focused on clock recovery circuit optimisation in direct detection optical communications. In 1985, he joined the Department of Electrical and Computer Engineering of IST. In 1992, he became an Assistant Professor, and he was promoted to Associate Professor in January 2002. He has lectured several courses on Telecommunications, and has been supervisor or co-supervisor of more than 30 M. Sc. theses and 10 Ph. D. theses. In September 2016, he became a Full Professor of the Department of Information Science and Technology of ISCTE – Instituto Universitário de Lisboa. He joined the Optical Communications Group of Lisbon site of “Instituto de Telecomunicações” (IT) as a researcher in 1992. He is now a senior researcher conducting research on optical fibre telecommunication systems and networks. He has been leader of the IST or IT participation in the five projects of the European Union programs on R&D in the optical communications area. He has been also leader of the six national projects in the optical communications area. In the past years, he has acted as a technical auditor and evaluator for projects included in “Advanced Communications Technologies and Services: european RTD” (ACTS) and “Information Society Technologies” (IST) European Union R&D Programs, and in national (Portuguese and other countries) R&D Programs. He has served as a reviewer for IEEE/OSA Journal of Lightwave Technology, IEEE Photonics Technology Letters, Optics Express, Optical Fiber Technology, IEEE Photonics Journal, IEEE Transactions on Communications, and other journals. He is a member of the IEEE Photonics Society, and IEEE Senior Member since November 2002. He has authored or co-authored more than 120 publications in peer-reviewed journals (17 as first author) mostly IEEE and OSA journals, as well as more than 160 international conference papers. He is co-author of two international patents. His main present research interests include fiber optic communication systems and networks.
