Research Interests

We are broadly interested in understanding the mechanics of sustainable polymeric materials, with a special emphasis on systems that are traditionally difficult to characterize, such as ultrathin polymer films (< 100 nm), engineered biofilms and engineered living materials. Our laboratory name, Huli Materials Lab, comes from the hua ʻōlelo(Hawaiian word), huli. Hulimeans to study, to change, and is a part of kalo(taro) that is replanted into the ground to produce new kalo. Kalois a highly sustainable food source and traditional food staple for Kānaka Maoli(Native Hawaiian people). Our group is inspired by the innate sustainability of the huli kalocycle to develop sustainable polymeric materials.
To achieve our goals, we developcharacterization and processing methods tailored for quantifying and programing the properties of both living and synthetic polymeric materials to fabricate sustainable polymeric materials for applications in biotechnology, sensing and protection. Our work is highly collaborative and multidisciplinary, combining expertise from mechanics, engineering, microbiology, materials science and polymer physics.
