Dr Reynaud obtained his BSc and MSc from University Bordeaux II Victor Segalen and PhD from University Paris XI-Orsay. Prior to joining UCD, Dr. Reynaud was a Postdoctoral Fellow and Researcher at the European Molecular Biology Laboratory, where his research focused on development of new imaging methods (e.g. Light Sheet Microscopy) and optical micromanipulations in Cell Biology (e.g. laser nanosurgery), in the laboratory of Prof. Ernst H.K Stelzer and Dr Rainer Pepperkok. He was also the co-founder of the Light Sheet Microscopy community alongside Dr Pavel Tomancak. He also developed and coordinated for 2.5 years a unique imaging platform TAOMI during the circumnavigation of the Earth as part of the Tara Oceans (2009-2012).

In 2009, he was appointed Lecturer in Integrative Biology at the UCD School of Biomolecular & Biomedical Science. His lab currently applies light sheet microscopy and 3D biological imaging technologies (e.g. photogrammetry) to the understanding of the biological world from single cell (evolutionary cell biology), to tissue engineered epithelial microtissues (e.g. 3D Bioprinting). He hold several patents and has extensively worked with companies as well as NGOs and other Irish or international laboratories. The ¿R lab¿ also develops novel software tools for 3D image analysis and 3D data visualization. He has authored over 80 peer-reviewed articles in English and in French, including articles in Science and Nature Methods, edited and illustrated several books and is actively involved in teaching worldwide (e.g EMBO courses). One of his reviews has been cited over a 1,000 times!

He is a Fellow of the Royal Microscopy Society and runs the Light Sheet Microscopy community and the ¿Rlab¿ ( Additional roles within UCD include Green Campus Committee, SPARC project leader and HortSoc allotment manager.

He has been involved throughput his career in humanitarian action, teaching science in developing countries and building scientific capacities (e.g. laboratories), supporting actions on climate change, recycling/upcycling and is a keen cyclist.

In September 2014, he was awarded by the French Government the Palmes Academiques at the rank of Knight in recognition for his works.

Dr Reynaud's interests include:
Evolution of cell compartmentalisation, Evolution of epithelial structure and function, Integrative 3D biological imaging, 3D bioprinting uses in Epithelial Tissue Engineering & Tissue Engineering

Research Interests

The Integrative Biology Laboratory or "R" Lab is a pluri-disciplinary laboratory focusing on the functions of epithelia. We use physics, chemistry, engineering, molecular and cellular techniques to study secretory pathways. We combine an evolutionary approach from Planctomycetes to Human to new biophysical and optical methods ranging from cell "morphing" to Light Sheet Microscopy for 3D imaging.

Our ultimate goal is to achieve a continuum of knowledge from single bacteria excretion capacity to complex tissue secretion ability in an organism context. For example, we currently studide epithelia functions at the molecular level within artificial epithelial tissues (lung, kidney, gut¿) to create optimal conditions for cell biology and molecular approaches as well as drug screening on specifically targeted functions: protein expressing defect (cystic fibrosis, lung), water retention (kidney diseases), tumor formation (Epithelial Mesenchymal Transition EMT, metastasis..) or even infections.

We also provide advices and optical set-ups to research groups and collaborate extensively with the private sectors (Carl Zeiss MicroImaging GmbH, Aquamarine Power Ltd, Aura Optik GmbH, Andor Ltd).
