Photoelectrochemical solar fuel production is a promising route for converting solar energy into clean, renewable fuel such as hydrogen. The greatest challenge towards efficient solar fuel production is in the design of photoelectrode materials that harvest light and drive electrochemical processes. Metal-oxides are particularly suitable as photoelectrode materials due to their abundance, low cost, and stability in aqueous solution – requirements that traditional semiconductors do not meet. Despite much progress, a path forward towards designing devices with high efficiency has remained elusive, partly due to electron-electron and electron-lattice interactions in these materials, which introduce deviation from conventional semiconductor behavior.
In this talk, I will demonstrate how we use epitaxial thin films as model systems to study the effect of light-matter interaction on photoelectrochemical behavior in complex metal-oxides. We combine these observations with time-resolved spectroscopy to show that excitation-wavelength-dependent charge carrier localization is an overlooked, yet fundamental limitation for achieving high efficiencies in several metal-oxide materials. We then develop a new method to quantify the spectral profile of the mobile charge carrier photogeneration yield in any thin film photoelectrode material and provide a path forward towards improved devices for solar energy conversion and storage.

Lymph nodes mediate the co-mingling of cells of the adaptive system to coordinate adaptive immune response. Drug delivery principles and technologies our group has developed to leverage the potential of lymph nodes as immunotherapeutic drug targets to augment anti-cancer therapeutic effects will be described
Continuous oozing is the number one bleeding problem in the surgical operating rooms, occurring in more than 50% of all surgeries, across different specialties all over the world. SURGICEL® Powder Absorbable Hemostat, a Class III medical device, was developed to control broad continuous oozing efficiently and effectively in open or minimal invasive surgeries when ligation or other methods of bleeding control are not possible. This presentation will walk you through how team brought a medical device to market, including identification of unmet needs, concept generations, new product development, commercialization, and teamwork.
Dr. Allen Y. Wang is currently a Global Technical Lead in New Product Development at Ethicon Biosurgery, a medical device subsidiary of Johnson & Johnson. In 2008, after obtaining his PhD from Johns Hopkins University, Allen joined Johnson & Johnson Wound Management R&D and quickly set the standard of excellence, holding over 70 patents and 45 patent applications worldwide and several peer‐reviewed publications, and developing several new surgical products to help more patients. His most recent Class III medical device invention, SURGICEL Powder Absorbable Hemostat, has served numerous patients in more than 45 countries since its launch in late 2017 and led to Allen and his team being awarded the 2020 Johnson Medal (a.k.a. Johnson & Johnson Nobel Prize) and several prestigious international awards such as the Gold Medical Design Excellence Award (MDEA) in the Drug‐Delivery Devices and Combination Products and the R&D 100 Award. Currently, he continues to work with J&J divisions globally to expand the Biosurgery product portfolio and generate novel surgical products for their future pipeline to address unmet surgical needs to enhance the health of people all over the world.
