Join Us!

Starting Fall ‘22, the 3DIM Lab will gradually move to the College of Optical Sciences at the University of Arizona as part of Prof. Willomitzer’s transition process.
We are always looking for motivated people interested in pursuing a research project or thesis in our lab. Prospective Students or Postdocs should have a background in Optics, Computer Science, Image and Signal Processing, or similar disciplines.
Please contact Prof. Willomitzer if you are interested.
