Dr. Yuen's research is based on carbon-related materials synthesis and materials analysis using microscopic techniques. He is experienced in thin-film deposition and engineering of nanostructures via Reactive Ion Etching (RIE), leading to mechanical, electronics, biological, and energy storage applications. 

Dr. Yuen's research and professional interests include the fabrication of diamond nanostructure array and its applications as well as the design, fabrication, and characterization of optical and optoelectronic applications.

Dr. Yuen specializes in material characterization techniques, including Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). He is also well-versed in different nanomaterial deposition methods such as Microwave Plasma Chemical Vapor Deposition (MPCVD), Hot Filament Chemical Vapor Deposition (HFCVD) and Physical Vapor Deposition (PVD). In addition, he also has extensive experience in designing, modifying, operating and maintaining ultra-high vacuum (UHV) components.

Prior to joining Exponent, he worked in a start-up company focusing on nanomaterials applications in the healthcare industry for water purification and PM2.5 particles elimination. The primary roles involve engineering polymer-based nanofibers with desired properties that meet international certification standards (e.g. ASTM, ISO, NSF, NOISH and GB) and functionalizing the fibers with organic or inorganic additives to exterminate bacteria and deactivate viruses, including SARS-CoV-2.

Dr. Yuen is also experienced in performing feasibility studies and risk assessments associated with scaling up and commercializing research efforts. He successfully commercialized two projects: Diamond Hard Coating for Drill and Electrospinning of Nanofiber for Filtration.
