Biography

Catherine Dubourdieu received her Engineer Diploma in Physics Engineering from Ecole Nationale Supérieure de Physique de Grenoble (INPG) in 1992 and her PhD degree in Applied Physics from J. Fourier University in Grenoble in 1995.

She spent 18 months as a post-doctoral fellow at Stevens Institute of Technology in Hoboken (New Jersey) and worked on the in situ characterization of gas phase and film growth by optical spectroscopies during chemical vapor deposition (CVD).

She joined CNRS in 1997 at LMGP in Grenoble, where she is now Directrice de Recherche since 2007.

She has supervised or co-supervised 13 PhD students. She is the co-author of over 95 scientific papers.

Her research interests are on the synthesis by CVD and on the properties of oxides heterostructures and nanostructures in relation with their micro/nanostructure.
In particular, she investigates size and strain effects on the crystalline, electronic and magnetic properties of functional oxides and work on strain engineering in thin films to finely tune their properties. Her current focus is, one one hand, on ferroelectric and multiferroic materials, and, on the other hand, on high k dielectrics.
She has investigated various aspects of CVD/ALD techniques: precursors benchmarking, process optimization, plasma use for low-temperature deposition. She also works on the integration of functional oxides in micro- and nano-electronics.

She is currently a member of the Bureau of the GDR CNRS 'Matériaux Multiferroïques' and a member of the ITRS (International Technology Roadmap for Semiconductors) working in the Emerging Research Materials group.

Since May 2009, she is a Visiting Scientist for one year at the T.J. Watson Research Center of IBM in Yorktown Heights, where she works on the integration of ferroelectric oxides on silicon.
