Hans van den Vlekkert
President and Chief Executive Officer & Co-Founder
Hans van den Vlekkert has been active in the MST for nearly 30 years. He has carried out research, as well as development work resulting in many products available on the market such as pH-ISFET systems and accelerometers.
During his career he has been responsible for marketing and sales (CSEM and TMP) as well as for production of Microsystems (Sentron, CSEM and TMP as head of silicon foundries and subcontracting higher volumes to other foundries and assembly companies. He has also been responsible for the Mesa+ Nanolab.
He was active in European programs as project leader for large projects such as Europractice and was also member of the board of Nexus and Eurimus. At present, amongst others, he is member of the board of IVAM and Project Coordinator of the large Memphis project (> 30 MEuro’s research program on photonics in the Netherlands). He has written over 50 papers and holds several patents in various fields.

Arne Leinse
Project/Account Manager and Vice-President

Arne Leinse received a M.Sc. degree from the University of Twente in the integrated Optical Microsystems group in 2001. In this same group he received his PhD in 2005 on the topic of active microring resonators for various optical applications (“Polymeric microring resonator based electro-optic modulator"). He is an expert in the field of integrated optics and has a lot of hands on experience in both designing and realization of MST components. In 2005 he joined LioniX as a design engineer and in the mean time he became active in several (European) research projects as project manager and involved in commercial customer requests as account manager.

Albert Prak
Chief Operations Officer
Albert Prak has 20 years experience in MEMS and microtechnology, from which 14 years in industry.
He is the founder of the MATAS integration technology for modular assembly of micro total analysis systems (a.k.a. Lab-on-a-Chip systems) and published the technology in influential journals and conferences. At 3T he subsequently worked as an engineer, designer and project leader in the product development of microfluidic systems for industrial applications. These projects involved i.e. pH-, conductivity-, flow- and ion sensors, micropumps, capillary electrophoresis, microelectronics and system control.
