Oleksandr Romanko won second place at the MITACS Annual Conference poster competition (Fredericton, New Brunswick). Oleksandr is working on developing optimization algorithms and applying them to real-world problems in risk management and finance. The poster "Credit Risk Portfolio Optimization" Oleksandr presented at the conference is the result of the research project on credit risk modeling and optimization. Optimizing credit risks, which are monetary losses due to defaults of counterparties to financial contracts, are especially important in the light of the recent financial crisis. Modeling of credit risk and developing optimization techniques for reducing credit risk impact on financial institutions and industrial enterprises were the major goals of the project. The research project was performed while Oleksandr was on a MITACS ACCELERATE Internship at Algorithmics Incorporated, Toronto.
