Subsequently, he became a postdoctoral fellow with Prof. Samuel J. Danishefsky at the Memorial Sloan-Kettering Cancer Center. In the summer of 2008, he moved to the University of Munich, where he worked a Professor of Chemical Biology and Chemical Genetics. In March of 2017 he returned to the U.S. to become the Janice Cutler Chair of Chemistry at New York University. Dirk is a recipient of the Otto Bayer Award, the Emil Fischer Medal, an ACS Cope Scholar Award, and a Sloan Fellowship. The broad objective of Prof. Trauner’s research is to demonstrate the awesome power of chemical synthesis and to use it toward the precision control of biological pathways.

Carlo Stresemann is a specialist on pharmacology, target validation and chemical biology in cancer. Prior to joining NUVISAN in 2020, he gathered his experience working for 12 years within research pharmacology at BAYER AG, where he started as a lab head leading drug discovery programs from early target validation until clinical development. He pioneered the field of epigenetic research at BAYER but also led projects targeting different other cancer pathways including survival signalling, metabolism, apoptosis, and cancer stem cells. Carlo is a Biologist by training and graduated from Heidelberg University. He holds a PhD since 2008 for studying DNA methylation changes and DNA methyltransferase inhibitors as therapeutic approach in cancer at the German Cancer Research Center (DKFZ) in Heidelberg.

Zuzanna Makowska is a scientist at the Functional Genomics Research department of the NUVISAN Innovation Campus in Berlin. She is a molecular biologist by training and performed her Ph.D. at the University Hospital of Basel, Switzerland, studying innate immune responses in viral hepatitis. After a postdoc at Max Delbrück Centre in Berlin, Germany, she joined Bayer as a scientist in the Target Discovery Technologies department. Zuzanna has been working for over ten years at the interface between functional genomics and big data analysis. Her current focus is on single cell sequencing and high content analysis of Crispr screens. 

Heidi Greulich received her undergraduate degree in molecular biology from Princeton University and her PhD in molecular oncology from The Rockefeller University and embarked upon a career in cancer research spanning academia, industry, and collaborations between the two.  At the Dana-Farber Cancer Institute and Broad Institute, Dr. Greulich studied oncogenic mutations in protein kinase genes, including EGFR, ERBB2, FGFR2, and ARAF.  More recently, as a Senior Group Leader at the Broad Institute, she has been focusing on the discovery and development of a new class of small molecules, called velcrins, that kill cancer cells by a completely new mechanism: induction of complex formation between PDE3A and SLFN12.  Testing of this therapeutic hypothesis in clinical trials is now underway in collaboration with Bayer.  Dr. Greulich is on the editorial board of Cancer Research and has been a keynote speaker for the annual Lung Cancer Research Foundation Cancer Awareness Luncheon in New York.
