I have blogged about Mikhail Elyashberg before and I wanted to take the opportunity to extend birthday wishes to him.
A tribute to Mikhail and his outstanding contributions in the area of Computer-Assisted Structure Elucidation (CASE) is published on the ACD/Labs website here.
At the age of 75 Mikhail is still working had in this area and you can stay tuned for a book on CASE coming soon. I will provide more details as they become available.
Congratulation Mikhail, and Happy Birthday!
