I finished my PhD in the Institute of Physics of the National University of México, working with Prof. Rolando Castillo. The title of my thesis was "Microrheology of thread-like complex fluids", were we analyzed the microrheological properties of several thread-like systems, such as wormlike micelles, polymeric solutions and rigid rod viruses, comparing their rheological behavior in terms of the structural differences among them, using a dynamic light scattering technique (DWS).
Then I joined Prof. Jose Luis Arauz research group as a posdoctoral fellow, analyzing the dynamical properties of mixtures of dumbbells and spherical particles under confinement and the interaction of optically anisotropic spherical colloids with complex fluids. More recently I became interested in the effects of laser-induced external fields on the dynamical properties of anisotropic colloids, developing not only experimental infrastructure but also theoretical tools. Then I moved to Germany to work as a posdoctoral fellow at the Experimental Soft Matter Group (Stefan Egelhaaf's lab) in Heinrich Heine University, Dusseldorf, studying the dynamics of colloidal molecules with laser-induced external fields. From August 2019 I am not at the University of Guanajuato (División de Ciencias e Ingenierías at Leon) as a Full Proffesor.
I am also interested on light propagation in turbid media, as the technique I used in my PhD is based in such phenomena. In particular we have studied the effect of absorption in DWS (in collaboration with Beatriz Morales), anb we have also developed new tools for the recovery of optical properties using GPU accelerated algorithms along with genetic algorithms. We are currently working in new methodologies for describing not only static properties but also dynamical properties of light propagating through colloidal suspensions.
