Spectroscopy and energies of the ground and excited states of LuF by multireference methods

Dr. Nuno M.S. Almeida

Timothé R.L. Melin

Michigan State University, Department of Chemistry, USA.

Short Bio: Dr. Nuno Almeida is a Research Associate at Michigan State University (MSU) under the supervision of John A. Hannah Distinguished Professor Angela K. Wilson. His current projects span from quantum mechanics to molecular dynamics, and heavy elements forbiologically relevant systems. He investigates the complex electronic structure of lanthanides and actinides using multireference methods. In addition, he is engaged in a number of drug discovery projects towards more impactful inhibitors for druggable proteins and receptors, including a partnership with a pharmaceutical company.  Nuno received his B.S. and M.S. degree in chemistry from the Faculty of Sciences at the University of Porto, Portugal, and a Ph.D. from Heriot-Watt University in Edinburgh, Scotland.

Short Bio: Timothé Melin is in his last year of his doctoral studies at MSU in Professor Angela K. Wilson’sresearch group.  His doctoral research focuses on the study of thermochemical properties of heavy elements (5d, lanthanides and actinides) using ab initio composite methods and DFT. He also employs relativistic Hamiltonians and multireference methods to investigate the bonding in lanthanide and actinide species. In addition, Timothé investigates gas-phase properties of a number of environmental contaminants using both ab initio and DFT methods and is engaged in the development of quantum dynamics approaches. Before coming to MSU, Timothé earned a B.S. degree from the University of Bordeaux, and a Masters in computational chemistry from the University of Paul Sabatier (Toulouse). After graduation, Timothé plans to return to Europe and welcomesdiscussions regarding job opportunities.
