Sascha studied Biology at the University of Konstanz in Germany and obtained his Diploma in 2004. He performed his Diploma thesis in the lab of Molecular Toxicology under the supervision of Prof. Alexander Bürkle working on the role of PARP in genome integrity and transcription. For his PhD studies, he moved from 2004 to 2009 to the group of Dr. Jean-Marc Egly at the IGBMC in Illkirch/France where he elucidated mechanisms how the human transcription machinery deals with DNA damage originated from byproducts of cellular metabolism and novel anticancer compounds. In 2009 he started his PostDoc at the EPFL in Lausanne working in the group of Prof. Joachim Lingner on the role of the noncoding telomeric RNA TERRA in Telomere function. In 2014, he joined the group of Prof. Josef Jiricny at the IMCR, University of Zurich working on the role of DNA mismatch repair proteins and their interactors on antibody maturation, DNA metabolism, and genome maintenance. From 2014 on he is also an active member of the LSZYSN. In his leisure time Sascha likes to go running, biking, hiking, and playing social games.
