While the focus of my research is computing technologies, the developed instrumentation enabled major scientific break-throughs achieved by the KATRIN~\cite{katrin2019limit} and ASEC~\cite{chili2010thunderstorm} collaborations.
Below are referenced selected peer-reviewed publications which are either authored by me and my students or where we made a significant contribution.
