Prof. Grigoris Kaltsas joined the Institute of Microelectronics of NCSR "Demokritos" in 1993 as a Ph.D. student. He received his Ph.D. in development and characterization of integrated thermal flow sensors, from the National Technical University of Athens in 1998. He is now Professor at the Dept. of Electrical and Electronics Engineering, University of West Attica. Prof. G. Kaltsas has participated and coordinated several European and national research projects funded by various foundations and industries. He has collaborated with many European research groups from various courtiers within the framework of several projects. He has published more than 170 papers in refereed journals and major conferences and he is an author of 5 patents, two of them being PCTs. He has been awarded by the minister of development by the General Secretariat of Research and Technology for the patent “Flow meter and special designed packaging for use in medical equipment for breath control”. He has more than 1080 citations with an h-index of 19 (source: www.scopus.com). He has participated in various committees and boards related to electronics – microsystems - sensors research and education. He was the Technical Program Committee chair for Eurosensors 2011, which was held in Athens. He is in the editorial board of MDPI Sensors Journal and Micromachines Journal. He is also a member of the International Program Committee of several major conferences in the area of Sensors and Micro-Nano Devices. He has presented several invited talks in various organizations regarding sensors, microsystems and microfluidics research and development, while he is an active referee in major journals in the microsystem area. He is the founder and the head of the Laboratory of “Microsystems, Sensors, Embedded Devices and Automation (microSENSES)” (http://microsenses.eee.uniwa.gr/). The microSENSES laboratory was established in order to enhance the research activities in the general field of microsystems, sensors, microfluidics and embedded devices. His research is mainly focusing in the following topics: Printed electronics, Flexible devices, Development of microsystems, Sensors, New microsystem technologies, Bio-sensors and bio-systems, Microfluidics, Embedded systems.
