Curriculum Vitæ

Catherine Dubourdieu received her Engineer Diploma in Physics Engineering from Ecole Nationale Supérieure de Physique de Grenoble (Grenoble INP) in 1992 and her PhD degree in Applied Physics from J. Fourier University in Grenoble in 1995. She received the Diplôme d'Habilitation à Diriger des Recherches in 2002 from Grenoble INP.

She spent 18 months as a post-doctoral fellow and Adjunct Assistant Professor 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, where she is now Directrice de Recherche since 2007.

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, on 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 has been teaching (> 1100 hours) at Undergraduate, Graduate and advanced levels at various locations such as Stevens Institute of Technology, Grenoble Institute of Technology, Joseph Fourier University, Collège de l'Ecole Polytechnique (Palaiseau) and the company Altis Semiconductors.

She has supervised or co-supervised 13 PhD students and 11 post-doctoral researchers.

From May 2009 until May 2012, she was invited as a Visiting Scientist at the T.J. Watson Research Center of IBM in Yorktown Heights, where she worked on the integration of ferroelectric oxides on silicon and on the Atomic Layer Deposition of novel oxides.

In June 2012, she joined the Institut des Nanotechnologies de Lyon (INL-CNRS). She currently works on the monolithic integration of functional oxides on semiconductors (Si, III/V, Ge) using molecular beam epitaxy (MBE).

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.

Award: Bronze medal CNRS 2001
