Biography

Gerasimos Vlachogiannakis obtained the diploma in electrical and computer engineering from the National Technical University of Athens, Greece in 2011 and the Msc degree (cum laude) in microelectronics in 2013 from the Delft University of Technology, the Netherlands, where he is currently working towards a PhD degree. He has been involved in the design of integrated cirtuit building blocks and full-chip designs in advance CMOS technologies such as microwave power amplifiers, and RF frequency synthesizers. His current research interests include mixed-signal, analog and RF integrated circuit design, and microwave measurement techniques. In his current research, he is involved in analog/Mixed-signal and RF circuit design for biomedical purposes (INFORMER project). He is a member of the IEEE since 2010.
