Summary


Had undergraduate (2006) and masters (2010) in Physics by Universidade Federal de Pelotas. Actually is doing her PhD at Complex Fluids group of Universidade Federal do Rio Grande do Sul (UFRGS), with "sandwich" stage at Institute for Computational Physics of University of Stuttgart. Has experience in computational simulations of complex fluids, mainly in: electrolyte and polyelectrolyte non-equilibrium simulations, confined complex fluids, grand canonical molecular dynamics, core-softened fluids flow in nanotubes.


Research


My main interest is computational and statistical physics applied to biological and chemical inspired problems. Since the beginning of my PhD, and so far, I'm working with equilibrium and non-equilibrium Molecular Dynamics simulations of complex fluids confined in structures as nanotubes, ionic channels and slabs.

A) Structural and dynamical behavior of water-like (core-softened) fluids in nanotubes - Equilibrium and non-equilibrium simulations

Using empirical core-softened potentials models for water-like liquids we study the dynamical and structural properties of such fluids confined in nanotubes. Molecular Dynamics simulations in canonical, grand canonical and isothermal-isobaric ensembles are applied to understand the unusual behavior that water-like liquids exhibit under nanoconfinement.

B) Electric-field mediated electrolyte and polyelectrolyte translocation through neutral and charged transmembrane channels

We develop a Molecular Dynamics dielectric model for cylindrical nanopores embedded in membranes. Such model has a low computational cost, allowing us to search properties of the system in long simulation time. This model was applied to understand the behavior of ionic fluxes through synthetic nanochannels with charged sites.
