It’s time to start another academic year! CELESE would like to welcome all the new students—both undergraduate and graduate—to the Faculty of Science and Engineering. We are greatly looking forward to working with you this year as we continue in these special circumstances. Although many other classes in the faculty will move to face-to-face teaching and learning, all CELESE courses will continue to be taught on-line. We have learned so much about on-line teaching during this past year and hope to make our classes even more effective and enjoyable for both students and teachers. Have a great spring semester!
