Experience

After getting his Ph.D. in mathematics, Nick worked in the biotechnology industry as a data analyst, working with large data sets to optimize corn to ethanol production. During that time, he also wrote about fantasy football and fantasy NASCAR for RotoViz. 

In 2016, he became a co-owner of RotoViz. Since then, Giffen has worked as a freelancer with FantasyLabs and the Action Network, before being hired as a full-time predictive analyst at Action in early 2022.

At Action, Giffen has developed in-game player prop models to live bet the NFL, which he uses on his show, Bet What Happens Live! He also pioneered Action's Luck Rankings, which have been used to bet NFL sides and totals successfully. 

Giffen frequently appears on several of Action's shows to talk NFL and college basketball, and he is a co-host of Running Hot, Action's motorsports betting podcast.

Education

Giffen graduated from James Madison University with a B.S. in Applied Mathematics. He earned a Ph.D. in Mathematics from N.C. State.

Betting Highlights
Favorite Bet of All-Time
I bet on my favorite driver Kyle Kirkwood at 20-1 to win the Long Beach Grand Prix. I went to the race and watched him win it in person for his first career IndyCar win. It was the first time I watched him race an IndyCar in person, so I'm officially his good luck charm.
