Short Bio

Jorge Castro-Godínez receveid his engineer degree ("Licenciatura") in Electronics Engineering and M.Sc. in Electronics Engineering (major on Embedded Systems) from the Costa Rica Institute of Technology. Currently, he is a scientist and PhD student at the Chair for Embedded Systems, Institute of Computer Engineering, Karlsruhe Institute of Technology, under the direction of Prof. Dr. Jörg Henkel.

Prior, Jorge worked as Embedded Systems Engineer at Canam Technology Inc. (https://www.canam-technology.com/) (2010-2012), and as a Lecturer at the Electronics Engineering School, Costa Rica Institute of Technology (2012-2014), where took part of a industry-joint research and development project between the Signal and Image Processing Lab and Bounce Imaging (https://bounceimaging.com/).

He has been reviewer and additional reviewer for conferences such as DAC, ICCAD, CASES, CODES+ISSS, and FPL; and journals such as IEEE TC, TCAD, TVLSI, and ESL.
