Dear QNN Group Members, Alums and Affiliates,

The summer and early fall has been rather busy in the group.  We have hosted two MSRP summer students, welcomed three new UROPs, and are excited to welcome former UROP Joey Alongi to the team as a graduate student RA.  We also said goodbye to Valentin Karam and Audrey Jacquillat who spent time as visiting students in the group over the last year.  We wish them the very best as they move on to bigger and better things!

Karl is enjoying the start of a busy sabbatical which involves saying “yes” to more travel opportunities and taking the time away from undergraduate teaching to focus on grant writing and research. 

Please see below a more complete list of the comings and goings, theses, papers, and conference presentations from the group since the last newsletter.   

Best regards,
Karl and Donnie

Comings and Goings
