I finished my PhD at 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," in which 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 their structural differences 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 dynamic 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. Since August 2019, I have been at the University of Guanajuato (División de Ciencias e Ingenierías at Leon) as a Full professor.
I am also interested in light propagation in turbid media, as the technique I used in my PhD is based on such phenomena. In particular, we have studied the effect of absorption in DWS (in collaboration with Beatriz Morales) and developed new tools for recovering optical properties using GPU-accelerated algorithms and genetic algorithms. We are currently working on new methodologies for describing not only static but also dynamical properties of light propagating through colloidal suspensions.
