Research Program

I worked in the field of immunology, especially in allergy and microbiology for many years.  I focused on the mechanisms of allergic responses as well as to identifying allergens from different sources which would help to lead to better diagnosis and treatment of this disease. My research was focused on recombinant allergen using various biotechnological methods. More recently, I joined the group of Jean-Luc Scemama and within this group collaboration with Joseph M. Chalovich.  We work on the role of synaptopodin/myopodin. This protein has been reported to be significant in cancer regulation and other cell responses.
