Progress in calculating the potential energy surface of H3+
Professor Ludwik Adamowicz, University of Arizona, USA
Ludwik Adamowicz was born in Warsaw, Poland, in 1950. He received his Ph.D. degree in quantum chemistry from the Institute of Physical Chemistry, the Polish Academy of Sciences, working in the group of Andrzej Sadlej. In 1980 he joined the group of Ed McCullough at Utah State University as a postdoc to work on diatomic MCSCF method employing numerical orbitals. In 1982 he moved to the Quantum Theory Project, University of Florida, to work as a postdoc with Rodney Bartlett on various projects involving the couple-cluster (CC) method (e.g. analytical gradient, first-order correlation orbitals, CC with numerical orbitals, etc.). In 1987 he was appointed as a professor at the University of Arizona, where he has been ever since. His research interests include development of multireference CC methods, methods for very accurate, explicitly correlated, Born-Oppenheimer (BO) and non-BO calculations of small atoms and molecules, methods for describing electrical conductivity and energy transfer in large heterogeneous molecular systems (DNA), as well as studies, mostly performed in collaboration with experiment, on molecular anions, on electronic and vibrational spectra of biomolecules, and on carbon-based materials.

Dr Oleg Polyansky, Russian Academy of Science, Russia
Oleg Polyansky received his diploma degree in radiophysics from the Gorky State University, USSR, (1979). The same year he became a junior research fellow at the Applied Physics Institute of the Russian Academy of Science (USSR at that time). His PhD work has been done at this Institute and defended at Tomsk University in 1993. By that time he was a senior research fellow of the same institute. After receiving his PhD he won the Humboldt fellowship, which he spent with Prof. Manfred Winnewisser and Professor Per Jensen in Giessen, Germany. In 1995 he took a postdoc position at University College London with Professor Jonathan Tennyson. He spent the years 2004 to 2006 as a researcher at Ulm University, Germany, and the years up to 2008 as a visiting professor at UCL. At the moment he is a group leader and leading research fellow in his home town (now called Nizhny Novgorod) at the Applied Physics Institute, Russia. His research interests are in the development and application of methods for the high precision calculation of the spectra of small molecules and ions, and analysis of their spectra at high excitation, including high temperatures and dissociation.

Dr Annemieke Petrignani, Leiden Observatory, Netherlands
Annemieke Petrignani completed her Masters in Applied Physics at the Delft University in the Netherlands, and received her PhD in 2005 at the FOM Institute for Atomic and Molecular Physics in Amsterdam. During this time, she worked closely with and at the Stockholm Univeristy and the Manne Siegbahn Laboratory in Sweden, performing experiments on small atmospherically relevant ions at the ion storage ring CRYRING. In 2002, she additionally fellowed at SRI International in Menlo Park, California, to construct an ion source for the preparation of quantum-state populations to study state dependencies. From 2006 to 2010, she was scientific researcher at the Max-Planck Institute for Nuclear Physics in Heidelberg, Germany. Here she performed spectroscopy on small molecular ions in both ion traps and the storage ring TSR, focusing on astrophysically relevant ions, mainly H3+. Currently, she is a scientific researcher at the Leiden Observatory in the Netherlands. She now studies larger molecules that are relevant to astrochemistry, specifically polycyclic aromatic hydrocarbons, performing experiments in ion traps with free electron lasers at the FOM Institute Rijnhuizen (as of 2012 called DIFFER) and the Radboud University Nijmegen in the Netherlands.
