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.

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).
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.
Yann Barrandon
Yann Barrandon graduated in Medicine in Paris where he also trained as a dermatologist and completed his PhD on the long term cultivation of human haematopoietic stem cells in 1982 under the direction of Dr. Catherine Dresch (Centre Hayem, St Louis Hospital). He worked as a post-doctoral fellow (1982-1983) with Pr. Marvin Karasek in the Department of Dermatology at Stanford University CA, and then with Pr. Howard Green, a pioneer in cell therapy, in the Department of Molecular and Cellular Physiology at Harvard Medical School (1983-1990). During this period, he participated in the world's first transplantations of epidermal stem cells on extensive third degree wounds and contributed several seminal findings including the demonstration of stem cells in cultures of human keratinocytes (PNAS 1987), and that human keratinocyte stem cells could be efficiently transduced by retroviral vectors (Science 1987), in collaboration with Richard Mulligan at the Whitehead Institute for Biomedical Research (Massachussets Institute of Technology, Cambridge, USA). He has also participated to the transfer of the stem cell technology from Harvard University to a spin off biotechnology company, now part of Genzyme Corp.
He returned to France in 1990 as Director of Research at the INSERM and Head of Lab at the Ecole Normale Supérieure, Paris. During this period, he demonstrated the presence of multipotent clonogenic stem cells in hair follicles (Cell 1994, 2001) and successfully brought stem cells from bench to bedside demonstrating the usefulness of a fibrin matrix to transplant epidermal stem cells. (Transplantation, 2000). Following his move to Lausanne, Yann Barrandon has shown that oligopotent stem cells are present in the mammalian cornea (Nature 2008), challenging previous dogma. He has also contributed to the characterisation of several skin diseases (Nature Genetics, 1993a, 1993b, 2000, 2005) and towards gene therapy of dystrophic epidermolysis bullosa. He is a partner in several EEC stem cell consortia (FP6: Therapeuskin and EuroStemCell, FP7: EuroSyStem, OptiStem, BetaCellTherapy).
Current research targets the role of small microenvironmental variations on stem cell behavior, and exploring the potency of stem cells of stratified epithelia (skin, esophagus, ocular surface) and of thymic epithelial cells. The lab is also involved in understanding the factors that regulate stem cell engraftment to improve epithelial cell therapy. An important aspect of the research aims at setting up a pilot clinical trial to demonstrate the feasibility of ex vivo gene therapy to treat Dystrophic Epidermolysis Bullosa, a rare but horrendous congenital disease of the skin that results in continuous blistering of the skin, chronic wounds, fusion of fingers and development of carcinoma.
