Biography

Virgilio Valente (S’09–M’11) was born in Milan, Italy, in 1979. He received the B.Sc. degree (first class honors) in electronic engineering in 2004 from the University of York, York, U.K., the M.Sc. degree in biomedical engineering in 2006 from Aalborg University, Aalborg, Denmark, and the Ph.D. degree in electronic and electrical engineering from University College London (UCL), London, U.K., in 2011. From 2011 to 2017 he held two post-doctoral positions as a Research Associate in the Analog and Biomedical Electronics Research Group at UCL, during which, in 2015, he also joined Tetrivis LTD, UK, as an IC design engineer. Currently, he is a Faculty Research Fellow in Bioelectronics, within the Department of Microelectronics at Delft University of Technology, Netherlands.

His research interests focus on the development of analog and mixed-mode CMOS integrated circuits for a range of applications, including Lab-on-CMOS and Organ-on-Chip platforms, implantable and injectable RF biosensors, CMOS-microfluidic devices and smart wireless telemetry systems.

Dr. Valente is a member of the Biomedical Circuits and Systems (BioCAS) Technical Committee of the IEEE Circuits and Systems Society (CASS) and the recipient of the 2017 EPSRC IRC i-sense Mobility Fellowship.
