Q: What is a fun fact about yourself?
A: I was an actuary right out of school and eventually earned my Fellowship in the Society of Actuaries, though I am no longer active as an actuary.
Q: How did you discover Expii?
A: I discovered Expii Solve through a link from 538’s Riddler, which I discovered after following 538 on Twitter.
Q: How do you use Expii?
A: Doing the problems is recreation for me. It is fun to learn branches of mathematics that I have not been exposed to in depth before, from spherical geometry to combinatorics.
Q: What is your math background?
A: When I was younger I was involved in math competitions, winning various statewide competitions between 7th and 12thgrades. I enjoyed competing on the state’s ARML team.
Q: What is your favorite area of math?
A: My favorite area of math is probability and statistics.
Q: Anything else yo would like to share about yourself?
A: Now I work as a “quant” trader for an option market maker. I develop algorithms to price and trade options and other financial derivatives. There is plenty of probability and statistics involved. Option prices essentially imply a continually changing probability distribution for the underlying asset at some future point in time. I use statistics when exploring historical data to identify market inefficiencies that are used to execute trades with good risk/reward characteristics.
