I have invited Professor Mengjie Yu of USC to give a Zoom seminar. She did her phd with Mchal lipson and postdoc with Marko loncar and just recently started at USC. She is certainly a premier expert in LNOI photonics. https://viterbi.usc.edu/directory/faculty/Yu/Mengjie https://purdue-edu.zoom.us/j/94820666697
