High throughput computation combined with combinatorial sputtering thin film synthesis and high throughput semi-automated measurements and characterization focused on screening and developing new nitride piezoelectric materials. Established a 20-member industrial advisory board to provide industry perspective and help with adoption of new materials. Developed piezoelectric (Al,Sc,B)N films that were quickly transitioned to pilot trials and fabricated the first ever oxygen-free nitride piezoelectric (LaWN3).
