Just an update to force myself to post. I've been working on a couple of video lectures, but am getting stuck on notational issues. These days I'm also fairly busy with writing. I'm currently working on a manuscript that is tentatively titled, "Modeling reaction-diffusion transport into a core-shell geometry." This might change, but not likely.
P.S. Yes, looking at this video now, I recognize how dizzy it is when I walk and talk using my camera. I either need to sit in future videos or use a camera that has a stabilizer built in.
