In the summer of 2002, two years into her PhD project, Yangyang developed a method for the templated synthesis of nanostructured polymers, where the templates used are multilayered porous silicon photonic crystals (Science, 2003 299, 2045). This work showed that a complex optical structure can be generated in almost any solution- or melt processible material using a nanostructured porous Si template. Yangyang’s second seminal contribution was to incorporate magnetic nanoparticles into porous Si photonic crystal hosts. Her PhD work resulted in 12 publications and 4 issued patents. For the summer 2003 Yang Yang applied for and received an internship position with Intel corporation in Santa Clara, CA. The summer at Intel exposed Yangyang to the world of corporate research in nanotechnology and in biotechnology.

Thesis: "Porous Silicon as a Platform Technology for Detection and Detoxification of Chemical Warfare Agents"
ORCID:0000-0002-2963-5953
Current Position: Post-Doc

Yi-Sheng “Eason” Lu earned his BS in Biomedical Engineering at National Tsing Hua University in Taiwan, his undergraduate thesis related to magnetic-responsive iron oxide nano-spheres for tumor therapy. He first joined the group as an MS student in the Materials Science and Engineering program at UC San Diego, and soon afterward he transitioned to the PhD program. A major goal of Yisheng’s PhD research was to utilize porous silicon as a host matrix to encapsulate enzymes and then evaluate their performance. Using porous silicon as a rigid support, he systematically studied the surface chemistries and nanostructures needed to effectively trap enzymes while retaining--and in some cases enhancing--their catalytic activity. This relied on a key breakthrough that is attributable to Yi-Sheng: his discovery of chemistries that allow trapping and stabilization of enzyme-based catalysts in porous silicon “cages”. He explored the utility of his approach with a number of enzymes, establishing as a general strategy that has become a major theme in our lab.

Joanna Wang was a Ph.D. student in Materials Science and Engineering (MSE) who joined the group in the summer of 2013. She participated in the 2013 Summer School for Silicon Nanotechnology and in subsequent years she served as a Senior Mentor. Her undergraduate research at the University of Illinois, Urbana/Champaign with Professor Paul Braun focused on polymers and polymer brushes. Her current research interests lie in the area of biomedical applications of polymeric nanocomposites. She led the project "Modeling of the vitreous for in vitro prediction of drug delivery of porous silicon particles and episcleral plaques" funded by the FDA. In 2019, she took a position as a post-doc in the Jianghong Rao research group in the Molecular Imaging Program at Stanford. In September 2021, she took a permanent position at Plexxikon.
