brigitte galliotDr. Brigitte Galliot is Associate Professor in the Department of Genetics and Evolution at the Université de Genève.  Dr. Galliot pursued her medical studies at CHU Necker-Enfants Malades/University Hospital St. Antoine in Paris, completed her internship at the University Hospital Center, Strasbourg, received a master’s degree in Human Biology from the University of Paris VI, and received a master’s degree in Molecular Biology and a Ph.D. in Life Sciences from the University of Strasbourg.

Dr. Galliot’s laboratory is interested in the molecular and cellular basis of regeneration and the regulatory networks that control adult and de novo neurogenesis.

To investigate these questions they are using the Hydra model system. Hydra is a simple freshwater cnidarian polyp that catches its food, contracts upon touch and walks thanks to a rather sophisticated nervous system. Moreover Hydra can regenerate any body part after bisection. Over the past 20 years gene cloning and genome sequencing highlighted the surprisingly high level of conservation of the signaling pathways from cnidarians to vertebrates. Hydra thus provides a simple but potent model system to investigate the core mechanisms driving regeneration in eumetazoans.

About the S. Meryl Rose Lectureship: 

The S. Meryl Rose Lectureship was established in honor of Dr. Rose’s distinguished career as a research scientist and his dedication to teaching. Dr. Rose conducted innovative zoological research with a major emphasis on the regeneration of limbs of amphibians. He received his M.A. from Amherst College in 1935 and his Ph.D. in Zoology from Columbia in 1940. 

During his career, Dr. Rose held professorships at Smith College, the University of Illinois, and Wesleyan University. From 1961 until his retirement, he was professor of experimental embryology and University Professor of Biology at Tulane University Medical School. Dr. Rose mentored 23 Ph.D. candidates and one M.D., encouraging all to develop and defend ideas even when they differed from his own. He authored and co-authored more than 50 published research papers, a number written in collaboration with his wife, Florence Rose, his long-time research co-worker and critic.

Dr. Rose spent many summers in Woods Hole doing research at the MBL He was course director of the Marine Embryology course from 1950 to 1955 and served two terms as a member of the MBL’s Board of Trustees. Dr. Rose was an avid sailor who loved sailing his sloop, Mystic, in Vineyard Sound. He will long be remembered by his students, colleagues, and friends for his great wit, devotion to science, boundless imagination, and unending generosity.
