Ian Williamson's website


Hello! I am a postdoc at Stanford University in the group of Shanhui Fan. I graduated with my PhD in Electrical Engineering from The University of Texas at Austin where I worked with Zheng Wang.

My research interest and background is in applied electromagnetics and nanophotonics, particularly for on-chip information and signal processing. These have been themes throughout my PhD research where I worked on projects spanning microwave, terahertz, and optical frequencies. I am also excited by the boundaries between optics, mechanics, acoustics, and other physics. Most of my experience is in approaching these topics from an analytical and numerical modeling point of view. As a result, I enjoy developing software and modeling frameworks for exploring new physics and devices.

Feel free to see my research and publications pages for more details on my work. At any given time my Google Scholar profile may be more up-to-date than this website. Also feel free to check out my GitHub where I have posted the codes for several of my projects.
