His research combines the synthesis, characterization, real-time imaging, and multi-scale modeling, to fundamentally understand the interactions and collective response of colloidal suspensions composed of anisotropic particles. His research interests aim to apply the fundamental understanding of the anisotropic particle behavior and interactions under the influence of external fields in various technologies, such as tunable/responsive materials, photonic materials, biosensors, tissue engineering, passive and active suspensions, drug delivery, hyperthermia, and cooling of electronic components, among others.
