Roark Chao

Graduate Student Researcher, ECE

Roark Chao is an Electrical and Computer Engineering (ECE) PhD student at the University of California, Santa Barbara (UCSB), where he is advised by Professors Jon Schuller and Steven DenBaars. Previously, he received his B.S. and M.S. in ECE from UCSB in 2024 and 2025, respectively, under the guidance of Professor Jon Schuller. His research seeks to combine machine learning (ML) and artificial intelligence (AI) with finite-difference time-domain (FDTD) and rigorous coupled-wave analysis (RCWA) models of light-matter interactions with the objective of demonstrating unconventional optoelectronics enabled by metasurfaces.

Arturo Juan (He/Him/His)

Graduate Student Researcher, Materials

Arturo Juan earned his bachelor’s degree in chemical engineering from the University of Southern California, then earned his master’s degree in electrical and computer engineering from UCSB. He worked in industry prior to entering the Materials PhD Program. Juan is advised by Steven DenBaars, a distinguished professor of materials and electrical and computer engineering. The focus of his research is on the epitaxial growth, processing, and characterization of wide-bandgap semiconductors for optoelectronic devices. According to Juan, working to improve the efficiency of materials that emit light could pave the way, for next-generation technologies having applications in optical communication, sensors, lighting, and quantum computing.
