May God bless you and your...
Greg and I worked for the same postdoc adviser (John Travis) at the NBS (now NIST). Our time there overlapped. Greg was an excellent colleague and contributed to a very good learning environment in the labs. We saw each other often when we were attending the same scientific meetings but not so much as our careers diverged. I was very saddened by the recent news of his passing. Greg was an excellent scientist and, better yet, an excellent person. He is gone too soon.
