Denis Duboule
Denis Duboule is born in 1955 and is both swiss and french national. He studied biology at the university of Geneva, where he obtained a PhD in mammalian embryology in 1984. He then spent 10 years abroad, first as a group leader in the medical faculty in Strasbourg (France), then at the European Laboratory for Molecular Biology (EMBL) in Germany. In 1993, he was appointed full professor at the university of Geneva, where he chairs the department of Genetics and Evolution ever since 1997. In 2001, he chaired the national center of research Frontiers in Genetics and in 2012 the division III of the SNSF. In 2006, he was appointed full professor at the federal institute of technology (EPFL) in Lausanne, where he leads the laboratory of Developmental Genomics (UpDUB).
His research activities are in the fields of embryology, genetics and developmental genomics of mammals, in an evolutionnary context. In particular, his laboratory has been closely associated with the structural and functional studies of mammalian Hox genes, by using mouse molecular genetic approaches. Duboule is also active in the communication of science, is member of the Academia Europea as well as of several academies in Switzerland, France and the Netherland. He is a foreign member of the Royal Society (UK) and of the National Academy of Sciences USA. He has received various scientific prizes and awards, amongst which the Marcel Benoist Prize, the Louis-Jeantet prize for medicine in 1998 or the international INSERM prize in 2010 (see also https://en.wikipedia.org/wiki/Denis_Duboule).
Johan Auwerx
Johan Auwerx is Professor at the École Polytechnique Fédérale in Lausanne, Switzerland, where he occupies the Nestle Chair in Energy Metabolism. Dr. Auwerx has been using molecular physiology and systems genetics to understand metabolism in health, aging and disease. Much of his work focused on understanding how diet, exercise and hormones control metabolism through changing the expression of genes by altering the activity of transcription factors and their associated cofactors. His work was instrumental for the development of agonists of nuclear receptors - a particular class of transcription factors - into drugs, which now are used to treat high blood lipid levels, fatty liver, and type 2 diabetes. Dr. Auwerx was amongst the first to recognize that transcriptional cofactors, which fine-tune the activity of transcription factors, act as energy sensors/effectors that influence metabolic homeostasis. His research validated these cofactors as novel targets to treat metabolic diseases, and spurred the clinical use of natural compounds, such as resveratrol, as modulators of these cofactor pathways.
Johan Auwerx was elected as a member of EMBO in 2003 and is the recipient of a dozen of international scientific prizes, including the Danone International Nutrition Award, the Oskar Minkowski Prize, and the Morgagni Gold Medal. His work is highly cited by his peers with a h-factor of over 100. He is an editorial board member of several journals, including Cell Metabolism, Molecular Systems Biology, The EMBO Journal, Journal of Cell Biology, Cell, and Science. Dr. Auwerx co-founded a handful of biotech companies, including Carex, PhytoDia, and most recently Mitobridge, and has served on several scientific advisory boards.
Dr. Auwerx received both his MD and PhD in Molecular Endocrinology at the Katholieke Universiteit in Leuven, Belgium. He was a post-doctoral research fellow in the Departments of Medicine and Genetics of the University of Washington in Seattle.
Michel Aguet
Dr. Michel Aguet, MD, held positions in academia and industry (Associate Professor at the Institute of Molecular Biology, University of Zürich; Head of Molecular Oncology, Genentech, So. San Francisco) before he was appointed director of the Swiss Institute for Experimental Cancer Research (ISREC) (1996-2009). In the context of the integration of ISREC into the Swiss Federal Institute of Technology (EPFL), he was appointed as Full Professor at the newly established School of Life Sciences in 2005. From 2001-2013 he directed the National Center of Competence in Research (NCCR) in Molecular Oncology, a national program launched by the Swiss National Science Foundation to encourage translational cancer research and for which ISREC was the leading house. Dr. Aguet has been a SAB member in the pharmaceutical industry, biotech industry and venture capital industry since 1997.
A large part of his scientific career was devoted to exploring the molecular biology of interferons (cloning of the interferon gamma receptor, generation of various interferon signaling mutants in the mouse) and, in collaboration with Prof. Charles Weissmann, to investigating the role of prion related protein PrP in mouse prion disease models. In recent years his research focused on characterizing the role of BCL9 proteins, which are part of the Wnt/beta-catenin transcriptional activation complex, in regulating stem cell traits in intestinal epithelium and colorectal cancer. His laboratory is now closed due to retirement.
Cathrin Brisken
Cathrin Brisken, MD, PhD, is Associate Professor of Life Sciences at the Swiss Federal Institute of Technology Lausanne (EPFL). Dr. Brisken is internationally recognized for her work on endocrine control of mammary gland development and breast carcinogenesis.
Dr. Brisken received her MD and her PhD degree in Biophysics from the Georg August University of Göttingen, Germany. She completed her postdoctoral work in cancer biology with Dr. R.A. Weinberg at the Whitehead Institute of Biomedical Research in Cambridge, MA, USA. She previously held appointments at the Cancer Center of the Massachusetts General Hospital, Harvard Medical School, Boston and the Swiss Institute for Experimental Cancer Research (ISREC).
Research in Dr. Brisken’s laboratory focuses on the cellular and molecular underpinnings of estrogen and progesterone receptor signaling in the breast and the respective roles of these hormones and hormonally active compounds in carcinogenesis. The aim is to understand how recurrent exposures to endogenous and exogenous hormones contribute to breast carcinogenesis in order to better prevent and treat the disease. The laboratory has pioneered in vivo approaches to genetically dissect the role of the reproductive hormones in driving mouse mammary gland development and shown how they control intercellular communication. Dr. Brisken’s group has developed ex vivo and humanized mouse models using patient samples to study hormone action in human tissues in normal settings and during disease progression.
Dr. Brisken is member of the International Breast Cancer Study Group (IBCSG) Biological Protocol Working Group. She served as Dean of EPFL Doctoral School (more than 2000 PhD students in 18 PhD programs), as member of the Hinterzartener Kreis, the oncology think-tank associated with the German Science Foundation, and numerous Swiss, European, and AACR committees. She co-founded the International Cancer Prevention Institute.

(San Francisco, USA). In 1997, he returned to Switzerland with Michel Aguet and finished his postdoctoral fellowship at the Swiss Institute for Experimental Cancer Research (ISREC) in Lausanne. From 1999‑2005, he was a group leader and Associate Member at the Ludwig Institute for Cancer Research. Freddy Radtke then joined ISREC in January 2006 as a senior scientist and in July 2006, he was appointed Associate Professor at the EPFL School of Life Sciences
Daniel Constam
Daniel Constam received his doctoral degree in Natural Sciences from ETH Zürich in the neuroimmunology group of Adriano Fontana (1993). For postdoctoral studies, he joined the laboratory of Elizabeth Robertson as an EMBO fellow at Harvard University to characterize proprotein convertase (PC) functions in mouse models of early embryogenesis (1994-1999). As an ISREC group leader (>2000) and Associate Professor at EPFL (>2007), he initially continued to study pluripotency and lineage differentiation during development and found that several secreted PCs jointly regulate cell-cell adhesion and TGFβ signaling pathways at the cross-roads of stem cell and cancer biology. To map the proteolytic activity of PCs and their relative distribution in exocytic or endocytic vesicles, his lab developed PC-specific FRET sensors for high resolution live imaging in normal cells and in tumour-host interactions. His studies on TGFβ signaling also identified the RNA-binding protein Bicc1 and its self-polymerization in membrane-less organelles as regulators of mRNA translation and cell metabolism that cooperate with primary cilia to prevent cystic growth in renal tubules and in pancreatic and bile ducts.
