Research:
My research interest mainly focuses on the locomotion and attachment of small animals and which are able to move freely in 3d spaces, and bio-inspired robots. Specifically, my work attempts to figure out the kinetical and dynamical principles of animals moving on 3d spaces, as well as the functions of their attachment devices to provided inspirations for adhesive structures and climbing robots.

With the capability of freely climbing on vertical walls and even ceilings, geckos have been providing us the best model for bio-inspired climbing and adhesion. With the combination of claws and hairy adhesive pads, geckos are able to obtain sufficient forces and freely move om various of substrates.

My present work involves understanding the geckos (Tokay) locomotion and strategies on unusual substrates, with the hope of understanding the basial principle of motion and providing guidelines for the design of bio-inspired robots.
