About Gu Research Group

Our iMedication Lab is interested in integrating biomaterials design, biomacromolecular engineering, and micro/nano-fabrication towards new drug delivery strategies, which apply stimuli-responsive systems for delivering and/or releasing therapeutics in dose-, spatial- and temporal-controlled manners. Our current focus is to leverage physiology for bioresponsive drug delivery through cellular carriers or biomimetic synthetic vehicles.
