QNN Quarterly Newsletter
Dear QNN Group Members, Alums and Affiliates,
Welcome to another issue of our quarterly(ish) newsletter. The group is feeling stable these days… new programs are starting and old ones are ending at about the same rate.
The high points of the past quarter were definitely Navid and Marco getting their PhD’s, and Owen, Andrew, and Emma getting their Master’s thesis completed. Congratulations all! We also have welcomed some new group members and are excited to watch them progress!
We hope you are all well, and feel free to drop a line to let us know your news!
Karl and Donnie
