Roberto Albornoz Martinez

Finance professional who uses analytics to make decisions, with an M.S. in Finance and a B.S. in Finance and International Trade, now completing an M.S. in Business Analytics (STEM-designated, Data & Methods concentration) at Boston University's Questrom School of Business, expected January 2027. More than eight years in finance roles before the MSBA: structured-finance credit analysis at S&P Global, AML and enhanced due diligence at Scotiabank, and financial planning and business development at Cine Colombia, where I directed exhibition and pricing strategy. My work centers on credit and prepayment risk, forecasting and stress testing, and turning model output into a decision a business can act on.
