Adolfo Cartaxo was born in Montemor-o-Novo, Portugal, 1962. He received the degree of "Licenciatura" in Electrical and Computers 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. In September 2016, he joined the Department of Information Science and Technology of ISCTE - Instituto Universitário de Lisboa as Full Professor. Over those years, 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. He joined the Optical Communications Group of Lisbon site of "Instituto de Telecomunicações" (IT) as a researcher in 1993. He is now a senior researcher conducting research on optical fibre telecommunication systems and networks, and national coordinator of Optical Communications Line in IT. He has been leader of the IST or IT participation in the following projects of the European Union programs on R&D in the optical communications area: project RACE 1051 - Multigigabit transmission in the subscriber loop - (1.10.1989 to 30.9.1990); project RACE 2011 TRAVEL - (HD)TV transport on very high bitrate optical links - (1.1.1992 to 31.12.1995); project ACTS 049 SPEED - Superhighway by photonically and electronically enhanced digital transmission - (1.9.1995 to 31.12.1998); project FP7-2007-IST-1-216785 UCELLS - Ultra-wide band real-time interference monitoring and CELLular management Strategies - (1.1.2008 to 31.12.2010); project FP7-ICT-2009-4-249142 FIVER - Fully-Converged Quintuple-Play Integrated Optical-Wireless Access Architectures - (1.1.2010 to 31.12.2012). He has been leader of the following national projects: project JNICT PBIC 2499/95 TÓPICO - Multigigabit optical transmission using electrical dispersion compensation - (1.1.1996 to 31.12.1997); project POSI/35576/CPS/1999 DWDM/ODC - Dense Wavelength Division Multiplexing Systems with Optical Dispersion Compensation - (1.10.2000 to 30.09.2004); project POSC/EEA-CPS/56959/2004 SHOTS - Super High-capacity Optical Transmission Systems - (1.4.2005 to 31.12.2007); project PTDC/EEA-TEL/104358/2008 TURBO - Transmission of UltRa wide-Band radio signals over Optical fibre - (1.12.2009 to 31.12.2012); project PTDC/EEI-TEL/2573/2012 MORFEUS - Metro networks based on multi-band ORthogonal FrEquency-division mUltiplexing Signals - (01.04.2013 to 30.09.2015); project AMEN - Analysis and Mitigation of crosstalk Effects in multicore fibre -based Networks - (01.04.2016 to 31.03.2018). 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 R&D Programs. He has served as a reviewer for IEEE/OSA Journal of Lightwave Technology, IEEE Photonics Technology Letters, Optics Express, IEEE Transactions on Communications, and other journals. He is a member of the IEEE Laser and Electro-Optics Society, and IEEE Senior Member since November 2002. He has authored or co-authored more than 130 publications in peer-reviewed journals (17 as first author) as well as more than 170 international conference papers. He is co-author of two international patents. His main present research interests include fiber optic communication systems and networks.
