About

Weida Liao is pioneering the frontier of optofluidics and microrobotics, where light and fluid dynamics converge to enable unprecedented control at the microscale. Their research centers on developing high-precision micromanipulation techniques that overcome the limitations of traditional optical tweezers, particularly constraints related to material properties and laser exposure. Liao’s major contribution lies in introducing model predictive control of laser-induced thermoviscous flows, a method that allows for the precise, multiplexed assembly and positioning of micron-sized particles in liquid environments. This work, detailed in their most-cited paper “Opto-fluidically multiplexed assembly and micro-robotics” (2024, 10 citations), opens new avenues for applications ranging from subcellular biology to advanced micro-robotics. By integrating axisymmetric thermoviscous and thermal expansion flows, Liao has expanded the toolkit for non-contact, high-definition manipulation. Their achievements represent a significant step toward fully automated, programmable micro-manufacturing and biological interrogation. With a growing citation record and a clear trajectory of innovation, Weida Liao is establishing themselves as a key figure in the next generation of optofluidic and microrobotic technologies.
