Informal Seminar Series --- Multi-D Group at IARC/Frontier

Our weekly/bi-weekly informal seminar series at the Multi-Disciplinary group at the Frontier/IARC, is held at 3:30 pm on Thursday in the IARC Building Room 401 or Room 417. Most presentations will be given by members of our group, focusing on presentations to be given in an upcoming conference, on going research activities, projects, or research proposals, and papers to be submitted or in press. In addition, guest speakers to be invited from external groups and institutions will complement our informal seminar. We welcome all interested ones to our seminar series. Please send Dr. Tomoyuki Tanaka or me an e-mail if you are interested in giving a talk or have questions/comments. Here is a list of previous seminars during 2000-2001.
