The ATTO Seminar (formerly UCF Ultrafast Journal Club) meets approximately biweekly to discuss recent research in the department on ultrafast, intense laser science and applications. Each seminar consists of either two 20-minute talks by current students or one 40-minute talk by a postdoc or faculty member. Please contact me (Mike.Chini@ucf.edu) if you wish to be added to the mailing list.
