Dr. Peter Koltay

Senior Scientist


Koltay, Dr. Peter

Dr. Koltay was born in 1968 in Stuttgart and studied physics at the Albert-Ludwigs-University of Freiburg and at the Eötvös Lorand University in Budapest. He graduated in 1996 and joined the Fraunhofer Institute for Solar Energy Systems in Freiburg, to conduct his doctoral thesis under the guidance of Prof. Dr. Joachim Luther. Parallel to his thesis Dr. Koltay conducted studies for a Master's degree in Business Administration at the University of Hagen from 1996 to 1999.

In December 1999, Dr. Koltay took a position as assistant lecturer at the department for MEMS applications at IMTEK and moved into the field of microfluidics. There, he started to establish the group, "microfluidics simulation" which deals with the simulation and modeling of microfluidic systems in general. Parallel to this activity, he was researching new methods for the dosage of micro-droplets and other non-contact liquid handling technologies.

In April 2005, Dr. Koltay founded BioFluidix GmbH  to develop the dispensing technologies of IMTEK into commercial products. Dr. Koltay is heading BioFluidix as managing director since then.

In October 2005, Dr. Koltay was appointed to become a professor of "Fluid Technology / Microfluidics" at the University of Rostock. In order to be able to continue his activities he refrained from accepting the professorship and stayed at IMTEK. Since March 2006, he belongs to the permanent faculty staff of IMTEK and works as senior scientist at the chair for MEMS applications and managing director of BioFluidix.

His special interests in microfluidics research and teaching are in the following areas:

  • The development of new technical methods for micro dispensing
  • Experimental methods for traceable volume measurements and sensors for online quality control of droplet dispensing systems
  • Theory and simulation of droplet formation, free-jet dispensing and all kinds of two-phase flow with free surfaces in a variety of applications
  • Computational fluid dynamics (CFD) with focus on microfluidic applications
  • Inkjet-like printing of biological cells for single cell analysis and bioprinting applications
  • 3D-prototyping and additive manufacture of metal micro structures by direct metal printing
