What do you like most about Axcella?
I’m extremely excited at the potential of our approach, technology and pipeline candidates to radically shift the way we think about supporting health and treating patients, especially in areas of unmet need. And of course, I’m drawn to the strong culture and people who make Axcella such a special company.

What is your greatest non-professional accomplishment?
Being the father of two great little girls.

Favorite movie?
Jerry Maguire – I love the comeback story

If you were a superhero, what super power would you have?
To manipulate time. I’d want the ability to make all of those memorable, but fleeting moments last longer – like the birth of your children or the Mets winning the World Series.

Favorite author?
It’s a tie between Haruki Murakami and Michael Lewis.
