Quantitative management of financial risks
2026

National University of Colombia

We delve into integrated risk management (SIAR) under the Colombian regulatory framework and combine theoretical foundations with quantitative modeling to measure and control market, credit, liquidity, operational, counterparty, and ESG risks. Through a flipped classroom approach, students develop stress testing analyses and applied solutions using computational tools.

Numerical methods in finance
2026

National University of Colombia

Advanced training in computational techniques for valuing derivative financial instruments under a risk-neutral measure. The program covers everything from binomial trees and Monte Carlo simulation to methods based on Fourier transforms and solutions to differential equations (PDE/PIDE). It focuses on the practical implementation of algorithms in Python, MATLAB, or R to solve complex financial engineering problems.
