This fall, Dr. Soon Wei Daniel Lim and Dr. Joon-Suh Park have successfully defended their theses. In their time in the Capasso group, Daniel has been working on singularity engineering with metasurfaces and Joon-Suh has been working on the development of metasurface fabrication protocols for both prototyping and mass production. Additionally, they have made both made invaluable contributions to the work of the entire group group in taking on responsibilities for group servers, this website and fabrication. We are all grateful, and wish both all the best in their future scientific endeavors!
