Ari joined the Board of Trustees in the fall of 2014, making him the youngest Trustee to serve Phi Psi. He was initiated into the California Beta Chapter at Stanford in 2006, where he served as Social Chair and Treasurer. He graduated Phi Beta Kappa from Stanford with a B.S. in Mathematics and a M.S. in Financial Mathematics.

Ari began his trading career before entering college on the grain trading floor of the Chicago Board of Trade. As the markets moved to electronic trading, Ari was able to trade while at Stanford with one caveat: he needed to wake up at 4 AM every day to actively participate. During his undergraduate years and continuing today, Ari is a contributing writer for TIME Magazine and TIME.com, focusing on economics, politics and financial markets.

After graduation, he moved back to Chicago and joined Traditum Group as Director of Automated Trading. He hired, and still manages, a team of computer programmers who work with traders to automate trading strategies. He used the profits from his early strategies to build his business and buy into the company.

He now serves as Senior Commodities Trader for Traditum, where Ari helped expand operations from primarily fixed income to agriculture, energy, currency, equity and metals markets. He has developed new agricultural commodities markets in North America and Asia, fostering international physical trade and helping farmers lock in profits and food manufacturers lock in cost margins.

Ari currently lives in Chicago and is working to publish his first novel. He is an accomplished guitarist and is teaching himself to play the acoustic drum set.
