15.00: Andrey Kovalevsky | 15.30: Marianna Yanez | 16-16.30: Discussion
Dr. Andrey Kovalevsky is a structural biologist, biochemist, and drug designer. Dr. Kovalevsky received M.Sc with Honors from Kharkov State University, Kharkov, Ukraine, and a Ph.D. from the University at Buffalo, the State University of New York. He worked at Georgia State University and the Los Alamos National Laboratory before joining the Oak Ridge National Laboratory, where he is currently a Senior R&D Scientist.
Dr. Kovalevsky’s current research focuses on studying the structure-dynamics-function relationships in macromolecular drug targets, including the design of protease inhibitors against SARS-CoV-2 and antidotes against nerve gas and pesticide poisoning, and studies of vitamin B6-dependent enzymes. His approach combines innovative biophysical and computational methodologies, such as X-ray and neutron crystallography at near-physiological conditions, vibrational spectroscopy with neutrons, biomolecular simulations, and structure-based virtual reality (VR)-assisted drug design.
Dr. Marianna Yanez Arteta is an Associate Principal Scientist at the Advanced Drug Delivery division within Pharmaceutical Sciences in AstraZeneca. In her current position she leads the development of new modalities drug products in pre-clinical and early clinical phases, including mRNA, antisense oligonucleotides and peptides. As part of her role, she has guided the development of nanomedicines for complex therapeutics from the understanding of the molecular interactions in the formulation.
Previous to this, Marianna was a postdoc researcher at AstraZeneca, where she investigated the structure of lipid nanoparticles for mRNA delivery using among other techniques neutron scattering. This work lead to a rational redesign of their composition in order to increase their efficacy. Marianna has a PhD in Physical Chemistry from Lund University, with considerable experience in the use of neutron scattering to investigate colloidal systems. She brings her expertise in scattering techniques to the screening of formulations in pre-clinical development.
Recent News & Events
- From 15 - 19 February 2021, over 80 participants attended the online LENS Machine Learning School. The school, which was targeted towards neutron and muon facilities staff, offered a gateway for beginner and intermediate coders to get into machine learning, providing an overview of modern and traditional machine learning techniques alongside neutron or muon based applications.
- Register for the RI.Logistica conference today and be part of an unparalleled international forum that will impact how research infrastructures deal with logistics in the future.
- REPLAY | LENS Webinar #9 on ‘Elucidating amyloid aggregation mechanisms behind neurodegenerative diseases’ with Emma Sparr (Lund University) & Pau Bernado (CBS/CNRS Montpellier)This webinar will focus on how neutron scattering techniques can elucidate the structures and steps involved in the aggregation mechanisms to provide crucial information to understand and combat these diseases and to develop better medications.
