Team leader


Thomas Konegger, Dipl.Ing. Dr.techn.


After completing his diploma studies in Technical Chemistry at TU Wien 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 for Structural Ceramics.

Publications and CV


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.


PhD student


Johannes Eßmeister, Dipl.-Ing. BSc.


Johannes joined our team in October 2018 for his diploma thesis, which he carried out in the framework of an FWF/CDG-funded project in collaboration with the Unterlass Lab.
In March 2020, Johannes started with his PhD thesis, which contributes to the FFG-funded PolyCat3D project. Here, Johannes develops polymer-derived ceramics suitable for additive manufacturing.


PhD student


Katharina Rauchenwald, Dipl.-Ing. BSc.


Katharina joined us in January 2022 after receiving her Master's degree at TU Wien, having her thesis conducted at the Austrian Institute of Technology (AIT). Before changing to TU Wien, she received her BSc degree in Chemistry at University of Vienna. In her PhD thesis, which is part of the TU Wien Doctoral School CO2Refinery, Katharina explores templating methods to create porous ceramic frameworks for CO2 conversion processes.


Master student


Lisa Schachtner, BSc


Lisa joined us in September 2021 for her Master Thesis, where she investigates the chemical modification of preceramic polymers for prospective catalysis applications.


Master student


Thomas Nothnagel, BSc


Since joining our team for his MSc thesis in February 2022, Thomas has been investigating the suitability of porous non-oxide ceramics for their potential use in thermal energy storage.


Master student


Anna-Maria Fuchsberger, BSc


Anna-Maria, who joined our Ceramics team in March 2022, carries out her Master thesis, which aims at introducing mesoporosity into polymer-derived ceramic materials suitable for additive manufacturing techniques.
