About My Research

My research interest encompasses the interactions between the molecular, cellular and physiological levels, and the role that environment play in their regulation. Today, I focus my research on the brain and the pituitary gland and their plasticity which allows differential hormone production, thus allowing the animals to adapt to their environment.

I mainly use transgenesis, tissue labeling and imaging techniques with teleost fish as model organisms.
