Prof. Stefan Vogt Geisse

Dr. Vogt Geisse did his undergraduate study at the Pontificia Universidad Católica, where he obtained his Licenciatura degree in the year 2008. He completed his PhD studies in the University of Georgia at the Center of Computational Quantum Chemistry in the year 2013. Afterwards he was awarded a Postdoctoral FONDECYT Fellowship: Elucidating the Polylactide Ring Opening Polymerization Mechanism of Novel Main Group Catalyst, for which he worked at the Pontificia Universidad Católica and University of Göttingen. Dr. Stefan Vogt joined the Department of Physical Chemistry at the University of Concepción in March 2016, where he is currently an assistant professor.

Reaserch line:
My research is in the field of ab initio quantum chemistry, in particular in the study of chemical reaction mechanism using wavefunction and density functional theory methods. In my current research grant, I propose to study the stereoselectivity of Al-salen type catalyst, in the polymerization of rac-lactide. This research grant is based on my previous work on the mechanism of the lacton ring-opening polymerization aluminum based initiators, where the reaction mechanism was studied combining local and explicitly correlated wave function based methods with DFT methods.

This research is enclosed in a more broader effort of mine to systematize and automatize chemical discovery and to build a second layer of chemical software on top of current quantum chemistry packages, that allow to extract chemically meaningful information from quantum chemistry data in a simple and straightforward way. In that context I have also developed a reaction path analyzing library called Kudi, which is written in Python and allows to effortlessly extract various reactivity indicators along a reaction coordinate.

Current Research Grants:
FONDECYT 11170949: Enantioselective rac-lactide ring-opening polymerization initiated by aluminum salen, salan and salalen complexes: Theoretical foundations. (2017-2020)
