Jinwook Lee, PhD
Professor Dr. Lee has expertise in optimization and risk modeling for evaluation and quantification of uncertainty — the key factors in the decision making processes. Over the past couple of years his research has been focused on modeling and designing artificial intelligence systems. Recently, he invented the hybrid blockchain algorithm which takes only desirable aspects from both central and distributed systems. He is an active scientist, his work has been published in European Journal of Operational Research, Operations Research Letters, Annals of Operations Research, Discrete Applied Mathematics and Computational Management Science, where one can find useful real-life applications of financial risk modeling, portfolio optimization, probability theory and related modeling, risk measures, corporate M&A deals evaluation, etc. Currently he works on reliability type inventory control problem, projection of distribution in an ordered vector space and bond portfolio optimization problem for insurance company.
Partially ordered datasets and a new efficient method for Conditional Value-at-Risk (2020) investigated and proposed a new efficient algorithm for the challenging computation of multivariate CVaR. Risk Tomography (2018) in European Journal of Operational Research presents how to measure risk and to find the best decision in complex multidimensional situations – “portfolio optimization” and “asset management” applications are investigated using recent real world datasets, demonstrating the new effective risk management tools. In Lee (2017) and Lee and Prékopa (2106) in Operations Research Letters, it is the connection between probability and geometry that enables us to efficiently solve many complicated problems on partially ordered data sets in a high dimensional space, together with recursive projections and a new counting measure. Lee et al. (2017) in Discrete Applied Mathematics, studies for sharp estimation of the future volatility levels of stock portfolios in terms of lower and upper bounds — any function of random variables can be systematically handled by the new methods. The new methods are proven more effective than simulation studies for the same purpose. Lee and Prékopa (2015) in Computational Management Science is one of the first articles presented quantitative evaluation of corporate M&As strategy. The new method provides decision makers with an evidence to support or reconsider their existing plan on the future M&As before taking action based on comparison of risks of before and after the event using the proposed techniques. In Lee and Prékopa (2013) in Annals of Operations Research one can find both theoretical and practical properties of the multivariate Value-at-Risk (VaR) and Conditional Value-at-Risk (CVaR).
