Interests, Projects, Ideas

 

My job is part time teaching and part time research. In my opinion, teaching is an exciting and a very challenging activity. You need to efficiently provide students with multiple and various knowledge, and most importantly you need to give them clues to acquire autonomy and sense of criticism so that they can handle problems by their own. This latter point is the great challenge of modern education, because nowadays information is accessible to anyone. Grenoble University of Sciences is an innovative place where teachers develop tools to help students toward success. I feel proud to be part of this adventure. As a researcher, I became fascinated by the beauty of cells. I am amazed by their so efficient organization, each organelle or molecule being at the right place at the right time, so that cells ensure their multiple functions and communicate with their environment. I am working on the internal cell skeleton, called the cytoskeleton, which is a dynamic network of cables and tubes that generate form and motion in living cells. I focus my interest on the microtubule network of neural cells, whose abnormalities are found in numerous neuropathies as Alzheimer disease. This research is done at the Grenoble Institute of Neurosciences, in Arnal’s lab. The place to be!
