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. He has worked as a university assistant until 2017. Since 2018, he is Assistant Professor.

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


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.


Master student


Gregor Mikl, BSc.


Gregor explores new approaches towards aligned pore structures in polymer-derived ceramics.


Bachelor student


Deniz Akgün


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


Bachelor student


Eva Szoldatits


Having started in February 2018, Eva investigates methods to control ice crystal growth in water-based ceramic suspensions in order to tailor the pore morphology in freeze-cast ceramics.


Bachelor student


Samuel Stelzl


Samuel joined us in April 2018 to work on his bachelor thesis project involving the preparation of nano-scaled oxide powders through a freeze-drying approach.
