Kyojin Choo
Professor Kyojin Choo received his B.S. and M.S. degree in electrical engineering from Seoul National University, Seoul, Korea, in 2007 and 2009, respectively. In 2018, he received his Ph.D. degree at the University of Michigan, Ann Arbor, MI, USA.
From 2009 to 2013, he was with Image Sensor Development Team of Samsung Electronics, Yong-In, Korea, where he designed signal readout chains for mobile/DSLR image sensors. From 2018 to 2021, he was with University of Michigan, Ann Arbor, MI, USA, as a Post-Doctoral Research Fellow, and he recently joined Swiss Federal Institute of Technology of Lausanne (EPFL), Switzerland, as an Assistant Professor. He holds more than 20 US patents and his research interests include charge-domain circuits, sensor interfaces, energy converters, high-speed links/timing generators, and millimeter-scale integrated systems.
Diego Ruben Barrettino
Diego Barrettino (S’93–M’98–SM’06) received the Dipl.-Ing. degree in Electronic Engineering from the University of Buenos Aires, Argentina, in 1997, and the Ph.D. degree in Electrical Engineering from the Swiss Federal Institute of Technology Zurich (ETHZ) in 2004.
He worked at Allegro MicroSystems Inc., from 1997 to 2000, where he was an Analog IC Designer of Hall-effect magnetic sensors. From 2000 to 2004, he was a Ph.D. student and Research Assistant at ETHZ, where he designed chemical and mechanical sensors. In 2004, he moved to the USA where he designed biomedical devices first as a Post-Doctoral Research Associate in the University of Washington, and then as an Assistant Professor in the University of Hawaii. In 2006, he returned to Europe where he joined the Swiss Federal Institute of Technology Lausanne (EPFL) as a Senior Research Scientist for the design and development of biosensors using organic nanotransistors. From 2007 to 2009, he was a Senior Lecturer in the University of Glasgow, U.K., and in the University College Cork, Republic of Ireland, where he designed ultra-low power biomedical devices. From 2009 to 2017, he was Full Professor and Head of the Laboratory of Microelectronics, Bioelectronics and Sensor Systems (LMBS) at the University of Applied Sciences of Southern Switzerland (SUPSI), where he designed smart contact lenses and eye implants. In 2017, he joined both the Lucerne University of Applied Sciences (HSLU) and EPFL as a part-time Senior Research Scientist to continue his work on smart sensor systems.
His research interests are in the fields of physical, chemical, and biomedical microsensors; sensor fusion algorithms; analog and mixed-signal IC design; MEMS; embedded systems; avionics and bioelectronics.
Diego Barrettino is a senior member of the Institute of Electrical and Electronics Engineers (IEEE), a member of the American Institute of Aeronautics and Astronautics (AIAA) and a member of the American Association for the Advancement of Science (AAAS).
Jonathan Graves
Prof. Jonathan P. Graves is a Senior Scientist at EPFL and Honorary Visiting Professor at the University of York, UK. He achieved first class joint honours in Electronic Engineering and Mathematics from the University of Nottingham, UK in 1996. He completed his Ph.D. in Theoretical Mechanics from the University of Nottingham, UK, three years later in 1999. During his Ph.D. he was based in the Culham theory group of the United Kingdom Atomic Energy Authority, developing kinetic descriptions of the internal kink instability, and participating in deuterium-tritium experimental analysis in the Joint European Torus. After a short time in industry, and a postdoc at Nottingham University, he took a position at the Swiss Plasma Center at EPFL, becoming a Senior Scientist in 2014, and became an Honorary Visiting Professor at the University of York, UK, in 2020. In 2015 he became a member of the EUROfusion Scientific and Technical Advisory Committee (STAC) and a member of the EUROfusion DEMO Technical Advisory Group. He is on the editorial board for the journal Plasma Physics and Controlled Fusion, and in 2020 became Scientific Secretary of the Varenna-Lausanne International Workshop in Theory of Fusion Plasmas.
Pavel Kejik
Pavel Kejik received the diploma degree in 1994 and the Ph.D. degree in 1999 at the Czech Technical University of Prague. In 1999, he joined the Institute of Microelectronics and Microsystems at the EPFL to work on Institute's circuit design and testing. His research interests include fluxgate magnetometry and micro-Hall sensors combined with mixed-signal IC design and low-noise circuit design for industrial applications. Since 2014, Pavel is with Monolithic Power Systems company (the EPFL spin-off company Sensima Technology SA before acquisition) actively working on industrialization of magnetic sensors. He is inventor or co-inventor of several patents related to novel magnetic sensing structures and methods in the domain of contactless current measurement, angular sensing and non-destructive testing. He is giving a lecture devoted to recent developments in the field of smart Hall microsystems within the frame of a yearly Europractice course
