Colloquium

The OSC Colloquium series is a dynamic forum for the interchange of ideas, techniques and research in all areas of optics, wherein academic scholars and industry leaders lead discussions about groundbreaking research and open the floor to questions and comments. Students, faculty members, members of the optics community and the public are all invited to attend.

Colloquium is held on Thursday in Meinel 307 each week during the academic year.
