[Soft-matter] Soft Matter and Complex Systems Seminar on 26 May 2023

[Maciej Lisicki]

Dear Soft Matter & Complex Systems Colleagues and Friends,

On Friday 26 May 2023 at 9:30 AM at the UW Faculty of Physics (Pasteura 5, Warsaw; room 1.40) we are hosting a seminar during which

Paweł Krupa (IF PAN)

will give a talk

Molecular dynamics simulations to understand biological systems

Abstract
Molecular modeling and simulations have become powerful tools for examining the structure, dynamics, and function of biological systems at atomic and molecular levels. As these methods continue to evolve, driven by advancements in software and hardware development, we can investigate larger and more complicated systems, extend simulation timescales, run more trajectories, and obtain more realistic results. Such capabilities allow us to reevaluate certain topics and uncover the limitations of oversimplified models used in both experimental and computational studies, which can produce physically correct outcomes that do not accurately represent much more complex physiological conditions. 
In this talk, I will present examples demonstrating how we can construct reliable models of lipid bilayers and investigate their behavior, as well as the impact of other molecules, including ions, neurotransmitters, and proteins as by proper employment of molecular dynamics simulations, we can gain valuable insights into the intricate interactions and dynamics of complex biological systems, which often are not possible to be investigated experimentally [1–5]
