My research is in friction-modulated surface haptics. During my PhD, I've studied the underlying mechanisms of how to manipulate friction forces on a screen, as well as how to use this technology to create compelling haptic experiences on touchscreen displays.

I'm currently working on texture representation and creation. How can we design a large set of distinguishable textures for our haptic screens, which are also defined by a usably small number of descriptive parameters that texture designers can set and modify? This work has led to the designation of pitch, gain, and irregularity parameters of friction-modulated microtexture, analogous to RBG specifications for color modification.
