Dohyun Ahn received a B.S. degree with a double major in Industrial & Systems Engineering and Management Science in 2011 and his M.S. and Ph.D. degrees in Industrial & Systems Engineering in 2013 and 2018, all from KAIST. His methodological background lies in applied probability, optimization, and stochastic simulation, whereas his application area includes, but is not limited to, financial engineering, risk management, and network analysis in finance and operations.
He received the ISE Best Thesis Award from KAIST, placed second at the 2015 INFORMS Section on Finance Best Student Paper Competition, and won the 2015 KORMS Best Paper Award. The paper “Analysis and Design of Microfinance Services: A Case of ROSCA” was highlighted in the December 2017 issue of ISE magazine published by the IISE. The paper “Shock Amplification in Financial Networks with Applications to the CCP feasibility” was selected as a Feature Article of Quantitative Finance.
