On November 1st 2013 I joined Prof. Stephane Bordas’ team in the Research Unit in Engineering Science at the University of Luxembourg.
Prior to this I studied for my PhD in the Department of Aeronautics at Imperial College London (2009-2013) under the supervision of Dr. Pedro M. Baiz Villafranca. My thesis, funded by the EPSRC through the Department of Aeronautics Doctoral Training Award, looked at how mixed variational methods, long used in the finite element method community, could be applied to the problem of alleviating the shear-locking phenomenon in meshless or meshfree numerical methods.
During my Master of Engineering at Bristol University (2004-2008) I developed analytical models for understanding plasticity in aluminium bars subject to three point bending.
I spent one year abroad at Rice University (2006-2007) where I developed Monte Carlo molecular simulations of cross-flow filtration processes.
Broadly speaking, my research interests lie in the field of Computational Mechanics. Within this, I concentrate on the following areas:
- Implicit boundary methods particularly suited to simulating models derived from medical images.
- Numerical method development; meshfree methods, XFEM and isogeometric analysis.
- Mixed variational methods in solid mechanics; particularly for the alleviation of volumetric and shear-locking.
- High performance computing; the development of partition of unity methods that can scale to modern distributed and parallel computing platforms.
All of my publications, conference presentations and theses are available for download under an Open Access license in the http://orbilu.uni.lu/ repository. Please don’t hesitate to get in contact if you think we could collaborate; I am very much open to new ideas and suggestions and I am keen to form new collaborations with researchers in academia and industry.
