Dr Tomaso Aste, Research Fellow, Australian National University.
Brief CV: Tomaso Aste is an acknowledged expert in the study of structural properties and dynamical evolution of non-crystalline media. He has developed new techniques for the statistical analysis of packings based on the idea of reducing the structure to skeletons of space-filling shells and minimal trees. Dr. Aste has also studied the simulated dynamics of packings through elementary moves, highlighting the importance of the local constraints on their global dynamical evolution. Dr. Aste is presently studying hard sphere packings by using computed tomography techniques. These empirical studies are the largest and most accurate studies of this kind ever attempted.
Brief summary of expertise and significant research achievements:
Dr. Aste has published more than 20 papers in the field. His book
"The Pursuit of Perfect Packing" is one of the best sellers of the
Institute of Physics Publishing. He is also the author of two patents.
Dr. Aste, has been visiting scientist at the Imperial College in London,
at the Department of Theoretical Physics in Oxford, at the Hong Kong University
of Science and Technology. He has been associated researcher (1996-1998) at
the Laboratoire des Fluides Complexes in Strasbourg, and at the
INFM (National Institute for the Physics of Matter) in Genova (1998-2001).
He has been granted with the Bacheflor Boncompagni-Ludovisi fellowship and
with the prestigious Individual Marie Curie Fellowship from the European
Union. He has presented results in oral communications and invited talks at
more than 30 important international conferences. He is referee for the
most prestigious international journals (including Phys Rev Lett and Eur
Phys J).
He won the 'best talk prize' in Aizu Wakamazu (Japan). Recently he has been
invited to give focus lectures on granular matter at the Max-Planck-Institut
for Complex Systems of Dresden (Germany). He is qualified as Professor in
French Universities (qualification aux fonctions de professeur des Universités).
The empirical and theoretical studies on packings which Tomaso Aste is
developing are contributing to the realization of a large database on
non-crystalline structures which will be made available for network
participants.
