For those who are keeping up, Colin had his preliminary defense this past week. This was a time when he defended his work before his thesis committee; they gave him the green light to graduate! In two weeks, he will present his final defense, which is open to the public. (Let me know if you want to come; his work is good and interesting and not so super esoteric that you'll be lost at the first word!) Between now and then, he needs to make minimal revisions to his already stellar thesis document. Then, on May 21, our daughter's 6th birthday, he will hand in his final draft and be done!!
Here's a shot of him coming up to our door after the prelim; we were looking down on him from our balcony.
