Alexander Levin is Director of Financial Engineering at Andrew Davidson & Co., Inc. He is responsible for developing new efficient valuation models for mortgages, derivatives, and other financial instruments and related consulting work. Alex has developed a suite of interest rate models that can be instantly calibrated to swap rates and a swaption volatility matrix.
