Teaching Interests
Introductory finance, dynamic asset pricing theory
Full-Time / Evening & Weekend MBA
Derivative Markets I (FINC-465-0)
This course covers the use and pricing of forwards and futures, swaps and options. Specific topics include strategies for speculation and risk management, no-arbitrage pricing for forward contracts, the binomial and Black-Scholes option pricing models and applications of pricing models in other contexts.

Asset Pricing I (FINC-585-1)
A doctoral-level course that offers an in-depth introduction to competitive asset pricing theory: arbitrage pricing, equilibrium pricing and optimal consumption/portfolio choice. Models are developed for a finite information tree, but from an advanced perspective that motivates and builds intuition toward continuous-time modeling.
