The people behind Biognosys



Dr. Oliver Rinner, Founder, CEO, board director 
Oliver graduated at the University of Tübingen in biochemistry and psychology , and then received his PhD in 2005 for his work in the field of psychophysics and molecular genetics from the University of Zurich. He joined the group of Ruedi Aebersold at the ETH Zurich as a PostDoc, where he published key papers and patents in the field of targeted proteomics and founded Biognosys in 2008.


Dr. Lukas Reiter, Chief Technology Officer 
Lukas graduated at the ETH Zurich in biochemistry/molecular biology. For his PhD he joined the groups of Michael Hengartner and Ruedi Aebersold and received his degree in 2009 from the University of Zurich. He published key bioinformatic papers in the field of shotgun and targeted proteomics. In his research he focused on the control of error rates and error propagation. This lead to the development of mProphet, the first tool to transfer these concepts to targeted proteomics. After completing his PhD he was a PostDoc for one year and in parallel started at Biognosys, working on professionalizing the software development and applying it to novel acquisition techniques such as SWATH.


Dr. Claudia Escher, Head of Scientific Operations 
Claudia graduated at the ETH Zurich in Environmental Sciences with a focus on biology and freshwater ecosystems. She obtained her PhD from the University of Basel, Department of Neurobiology (group of Markus A. Rüegg) and the University of Applied Sciences Northwestern Switzerland for her work in biomarker discovery with mass spectrometry. Claudia joined Biognosys in 2008 and is responsible for the operations department focusing on contract research projects.


Dr. Stephan van Sint Fiet, Chief Commercial Officer 
Stephan has 8 years of experience in the biotechnology industry across marketing, business development and R&D. He joins Biognosys from Novozymes, a leading Danish biotechnology company, where he was Global Marketing Manager for 4 years. Prior to that, Stephan was a business developer at Evolva, an innovative Swiss biotech company. He started his career in biotechnology as a research group leader at Evolva. Stephan graduated from the ETH Zurich in biochemistry and for his PhD joined the group of Bernard Witholt at the Institute of Biotechnology, ETH Zurich, focusing on protein engineering and high-throughput biocatalyst selection. Stephan holds an MBA from the University of St. Gallen.

Scientific advisory board

Ruedi, co-founder of Biognosys, is one of the pioneers in the field of proteomics. He serves on the Scientific Advisory Committees of numerous academic and private sector research organizations and is a member of several editorial boards in the fields of protein science, genomics, and proteomics.

Johan, Associate Professor at the University of Lund, Sweden, obtained his PhD in a joint collaboration between Lund University and AstraZeneca R&D Lund. In 2001 he co-founded Ludesi AB. In 2003, Johan joined the Institute for Systems Biology in Seattle and in 2004, he transferred to the Aebersold lab at the ETH Zurich, where he was involved in the development and application of targeted proteomics technologies and co-founded Biognosys.

Paola obtained her PhD from the University of Padova. In 2006, she joined Prof. Ruedi Aebersold’s group at ETH Zurich, where her research received the ETH Latsis Prize 2011. At the beginning of 2011, she started her own research group and was appointed assistant professor at the Institute of Biochemistry at ETH Zurich.
