Drug Delivery, Biosensing, Active Matter, Soft Materials, Colloid and Interface Science, Microfluidics
Our group is broadly interested in biosensing and drug delivery. The distinguishing approach we take is through engineering particle systems, especially those that interface with biology and controllably respond to external stimuli. We work at the intersection of materials, soft matter physics and bioengineering to rationally design colloidal and supracolloidal particles for a range of applications. We take inspiration from nature, which efficiently assembles matter across length scales that encode a rich variety of behaviors when stimulated by energy. We have three guiding objectives, to: 1) understand how particles interact in and out of equilibrium and, in turn, how to control their behaviors by tailoring their nano and microscale properties such as shape, size and composition; 2) apply new insights to create collections of "smart" particles that perform useful tasks such as actuate and release encapsulated payloads; and 3) integrate our pipeline of new materials to advance biosensing and drug delivery by developing new diagnostic and therapeutic platforms for a variety of indications.
