Our research group is based at the University of Puerto Rico – Mayagüez and is led by Prof. Ubaldo M. Córdova-Figueroa. We specialize in the theoretical study of soft matter and complex fluids through numerical simulations, which allow us to predict the dynamic behavior of various colloidal systems and analyze their microstructure, which governs their rheological and mechanical properties. Specifically, we examine colloidal systems composed of different types of Janus colloids, including both passive and active particles. The inherent anisotropies in Janus colloids offer a wide range of dynamic behaviors in self-assembly and directed-assembly processes, such as those involving magnetic Janus colloids, patchy Janus colloids, Janus droplets, as well as liquid crystal systems. These systems have a variety of applications, including soft robotics, cancer treatment, drug delivery, magnetic resonance imaging, chemical sensing, and environmental remediation.
