The Biocomplexity Department

Head

prof. dr hab. Ewa Gudowska-Nowak

Profile

Our aim is to devise and develop theoretical mathematical and computational techniques for analyzing biological systems of various complexity. In particular, we design methods allowing analysis of fluctuating time and spatial series. The team specializes in various aspects of continuous time random walks in crowded environments as models of biological motility, network modeling of epidemics spreading, biochemical kinetics in proteins and channel-gating mechanisms studied by use of the theory of stochastic diffusion, molecular dynamics and quantum semi-empirical calculations of electronic structure. By using tools of the information theory and signal propagation, we address problems of constructive effects of multiplicative (external, environmental) noises and additive (internal) fluctuations on critical behavior of nonlinear biological systems. 

Our collaboration with experimental groups, especially with Biophysics Division, GSI HelmholtzzentrumfürSchwerionenforschung GmbH has advanced understanding mechanisms of induction of radiation damage to biological materials, assemblage of chromosome aberrations and biodosimetric assessment of health risks associated with exposure to ground  and cosmic radiation. In accordance with research performed in laboratories of the Marian Smoluchowski Institute of Physics, Jagiellonian University, we analyze characteristics of intracellular transport, study thermodynamic models of energy conversion efficiency in entropy-driven nanomotors and investigate collective phenomena of molecular transporters. 

Motivated by innovative applications of the theory of complex systems in understanding brain-organization and emergence of consciousness, we have launched a common program of research with the Neurobiology Department to expand methods of fluctuation analysis and random matric theory (RMT) in information processing (Dense Array EEG, functional MRI, MEG) and studies of adaptive and learning phenomena in neural networks. 

The group pushes also forward the application of recently developed techniques of 3d printing to biotechnological applications. This research involves dedicated software development and construction of 3d biological printers. The ultimate goal is to construct 3d environment for drug testing and verification of the simulation methods. 

The Department Head is prof. Ewa Gudowska-Nowak (BIOLAB, Mark Kac Complex Systems Research Center and Marian Smoluchowski Institute of Physics, Jagiellonian University) http://th-www.if.uj.edu.pl/zfs/gudowska/gucia.html whose field of expertise covers theory of stochastic processes, selforganization and nonequilibrium thermodynamics.
