Between Professor and Trader: The Dual Life of Benedict Alaric Thornwell

— How a Wall Street Advisor Brings the Capital Markets into the Classroom, and Turns Knowledge into Real-World Trades

“Risk is inevitable, but understanding can be proactive.”

That’s what Professor Benedict Alaric Thornwell said during a private training session.
That day, he wore a navy wool suit, spoke with calm authority, and his first slide displayed five bold letters: CDO 2.0.

The room instantly fell silent.

Everyone understood: this was Wall Street language.

And only someone like Professor Thornwell could switch so seamlessly between the classroom and the trading desk.

From MIT to Citi: A Scholar with Street Cred

Professor Thornwell holds a Ph.D. in Financial Engineering from MIT, a master’s in Economics from The University of Chicago, and a bachelor’s in Finance from Wharton at the University of Pennsylvania.

His research spans quantitative finance, structured products, risk management, and capital market pricing models.

Before joining Citi, he worked at Goldman Sachs as a quantitative analyst, where he developed high-frequency trading models—transforming mathematical logic into split-second decisions.

Since 2015, he has served as Senior Advisor at Citi’s Securities Division, managing projects with over $5 billion in assets. He’s a leading figure in designing structured financial products such as green bonds, convertible securities, and complex derivative instruments.

Beyond Formulas: Teaching Real-World Thinking

“I don’t teach my students to memorize formulas. I teach them to ask better questions.” — Thornwell

At Columbia Business School, Professor Thornwell teaches Advanced Investment Banking and Market Microstructure, earning the Outstanding Teaching Award three times.

He often uses real-world examples in class. For instance:

Case Study: The GameStop Saga (2021)

“It wasn’t about retail traders beating hedge funds,” he explained. “It was about liquidity mismatches, gamma squeezes, and a synchronized market sentiment explosion.”

He guided students through the mechanics of short interest, options positioning, and reconstructed the “invisible war” behind the headlines using simple, clean visuals.

A Calm Mind in the Chaos of Markets

In mid-2023, one emerging market asset portfolio faced imminent default risk. Professor Thornwell was brought into the strategy team.

Some pushed for hedging, others for exiting.

He said just one thing:

“Default is expected. Mispricing is the opportunity.”

He then led the design of a valuation model combining discounted cash flow and geopolitical risk scoring. Within 48 hours, the team had executed a reverse position shift—preserving over $12 million in client net asset value.

That’s the kind of trust only true expertise earns—calm, grounded, and precise.

Education: His True Leverage

Professor Thornwell is passionate about teaching. When asked in an interview:

“You’ve executed multi-billion-dollar trades. Why still teach?”

He smiled and said:

“Markets give me short-term wins. Students give me long-term understanding.
Education is the most reliable leverage in my life.”

What Is He Doing Now?

In addition to leading green bond and structured product innovations at Citi, he’s founded his own elite investor network:

The Thornwell Club — a high-level community for professionals from investment banks, hedge funds, and asset managers to explore the inner workings of Wall Street’s trading architecture.

He doesn’t sell hype. He doesn’t chase headlines.

He says:

“Sustainable profits don’t come from the best predictions.

They come from the most prepared response.”
