Research

The Sadati lab will pursue a bottom-up approach to study the structure, dynamics, and self-assembly of soft materials, with an emphasis on anisotropic components capable of leading to new, tunable macroscopic properties. Through systematic studies of self-assembly, topological defects, and real-time structure and rheology, we will engineer responsive materials with unique architectural features designed for a broad range of applications including tissue engineering, actuation, drug delivery, controlled cargo transport, and biosensing.

Theme I: Active Matter in Complex Environments

A common feature among natural microswimmers such a bacteria is the ability to convert energy to motion and regulate their self-propulsion in response to external stimuli. Inspired by the biomechanics of nature, artificial active micromotors are being developed that can transduce the local energy to directed motion and to propulsion. These artificial micromotors have been envisioned for a broad range of applications such as drug loading, controlled release in the vicinity of cells, and water remediation to name a few. In many of these applications, these micromotors have to move in a complex environment. We will explore the micro-rheology of microswimmers in complex environments to design autonomous micromachines that can navigate efficiently in realistic condition of operations.

Theme II: Additive Manufacturing: In-situ Characterization, Process Optimization, and Material Design

Despite the growing interest in the 3D printing of soft materials and polymers, the precise control over the manufacturing process through optimization of structural properties and processing conditions remains essentially unexplored. We will combine 3D printing process with diverse in-situ characterization techniques, including velocimetry and Rheo-optics to develop designer materials for specific applications. In-situ characterization provides fundamental information for material optimization and product design. Moreover, by acquiring precise experimental flow kinematics in complex flows, our work will enable development of theoretical models. Combined experimental and theoretical studies will then be used for rational design of 3D-printed soft materials for tissue engineering, shape morphing systems, and soft sensors.
