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).

PhD student


Johannes Rauchenecker, Dipl.-Ing. BSc.


Johannes first joined our group for his bachelor thesis in 2016, working on the control of porosity in SiCN-based ceramics, and also did his master thesis in the framework of the MICROPORE project, which he completed in June 2018.
In his PhD thesis, part of the ADDHANCE project, he investigates new approaches towards shaping of aluminum nitride ceramics.


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 Eßmeister, BSc.


Johannes joined our team in October 2018 and carries out his diploma project in the framework of an FWF/CDG-funded project led by Miriam Unterlass. In collaboration with the Unterlass Lab, Johannes develops polyimide-based composites and evaluates their mechanical and structural properties.


Master student


Felix Frank, BSc.


Having joined our team in December 2018, Felix works on the development of polymer-derived ceramic membranes in the framework of the MICROPORE project.


Project assistant


Deniz Akgün


Deniz supports our group in several processing- and characterization-related aspects, including the mechanical evaluation of ceramic materials.


Bachelor student


Christian Wimmer


Christian's bachelor thesis project involves the preparation and characterization of polymer-derived ceramic membrane materials.
