The 2003 Jeopardy! College Champion, I pair a thirst for understanding with a knack for explaining complex concepts in simple terms. 11-time champion Arthur Chu called my tutorials on The Final Wager "invaluable" to his success.

As a journalist, I have bylines in The Wall Street Journal, The New York Times, and several other publications. (Here's my complete list of credits.) I still update my initial foray into writing, The Weekly Nabe, a blog on the past and present of Brooklyn neighborhoods.

I'm comfortable in other forms of media, too: I've given well-received interviews on NPR, CTV, and CNBC.

Before going into writing, I spent four years at Goldman Sachs, elucidating the changing derivatives market through white papers shared widely, both internally and in the industry. I graduated cum laude with a degree in economics from Middlebury College.

"[Keith's] innovation wasn’t the theory itself but being able to describe the theory in a clear, cogent way so that even a Jeopardy! beginner like me could follow it." --Arthur Chu, #4 all-time in regular Jeopardy! winnings
