Marco Antoniotti
Marco Antoniotti was a researcher at NYU were he developed Bioinformatics applications using (among other things) Common Lisp. He is now a professor in the Department of Informatics, Systems and Communications of the Università degli Studi di Milano-Bicocca where he continues to do the same, plus inflicting Common Lisp on his students. He is also a Person on CLiki.

He is almost an old geezer who never touched a Symbolics machine (or a Xerox or a TI). However, has been fond of MCL and CMUCL.

You can find out a little more about him at the Data and Computational Biology site and on Linkedin.

Some Common Lisp things he did include some code in the CLOCC, maintaining MK-DEFSYSTEM and several other libraries. His (within-parens) blog is a good place to keep up with them.
