Interests and expertise

Topics: Immunology, innate immunity, helminth infections

Cells: Natural killer cells, macrophages, neutrophils, dendritic cells, eosinophils

Techniques: Luminex, flow cytometry, immunohistochemistry, chemotaxis assays, Western Blots, adoptive transfers

Projects

Immunology and parasitology

These 2 topics are closely interlinked - parasites need to escape/avoid the host immune response to invade their host and the host immune system needs to recognize and eliminate the parasites. They both continually learn from each other and are trying to come up with new strategies to win the fight. This is a remarkable and fascinating example of coevolution - but not really a love story !

I am exploring this in more details, dissecting immune responses to helminth parasites infections. I am particularly interested in Natural Killer cells, which are not usually described as playing a crucial role in innate immune response to helminth infections but which might be more important that we thought…

Teaching

BSc (Hons) Biomedical Science

MSc Biomedical Science

MSc Clinical Science

Why do I teach?

I like to share my knowledge and my passion for immunology and parasitology.

How I will teach you?

Interactive lectures, tutorial group discussions, support and advices during practicals, quizzes… let’s find a way for learning immunology without getting a migraine.

Words of wisdom

Think creatively, think differently and keep believing
