Current team members:

Team leader

Thomas Konegger, Dipl.Ing. Dr.techn.


After completing his diploma studies in Technical Chemistry at Vienna University of Technology with a focus on chemistry and technology of materials in 2007, Thomas received his PhD in 2010, with a research focus on polymer-derived ceramics. Since then, he has held a position as university assistant (Universitätsassistent) and team leader of the research group “High-performance ceramics”.

Publications and CV

PhD student

Christina Drechsel, Dipl.-Ing. BSc.


Christina initially joined us for her master thesis in May 2015 where she worked on multiscalar polymer-derived ceramic layer structures. After her graduation in September 2016, she has continued working in our group for her PhD project, where she investigates the generation of microporosity in polymer-derived ceramics in the framework of the MICROPORE project funded by the Austrian Science Fund (FWF).

Master student

Dominik Brouczek, BSc.


Dominik completed his bachelor’s thesis in our group in 2013, where he worked on the investigation of reaction-bonding processes in mullite-based cellular ceramics. In 2015 he joined us again for his master thesis, doing research on the development of casting approaches for the shaping of Si3N4 ceramics.

Master student


Thomas Prochaska, BSc.


Thomas joined us in October 2016 for his master thesis, where he works on the tailoring of open porosity in Si3N4-based ceramic materials in the framework of the MICROPORE project.



Master student


Richard Obmann, BSc.


In 2015, Richie had already worked in our group for a short-term individual lab on porous polymer-derived ceramic structures. Since June 2017, he has been working on his master thesis project, again dealing with pore tailoring in polymer-derived ceramics.


Master student


Johannes Rauchenecker, BSc.


Johannes first joined our group for his bachelor thesis in 2016, working on the control of porosity in SiCN-based ceramics. In October 2017, Johannes became part of our group again for his master thesis, which he conducts as a project assistant in the FWF-funded MICROPORE project. In his work, he explores new methodologies to create ceramic structures with asymmetric porosity.



Master student


Matthias Nebel, BSc.


In his Master thesis, Matthias explores new ways to modify the structure of preceramic polymers in order to tailor structural changes during the polymer-to-ceramic conversion process.


Bachelor student


Deniz Akgün


In her bachelor thesis, Deniz investigates the freeze templating technique to generate porous structural ceramics.


Bachelor student


Yiji Lin


Yiji joined us in August 2017 for his bachelor thesis. His main topic is the generation of mesoporosity in polymer-derived ceramic materials.


Bachelor student


Georg Ebmer


Georg started in our group in September 2017. In his bachelor thesis, jointly conducted with the Electrochemical Methods and Corrosion Laboratory, Georg develops porous and non-porous zirconia ceramics for oxygen sensors.
