About

Welcome!

Diego Klabjan’s research is focused on genAI, LLMs, deep learning, reinforcement learning, and other topics in machine learning and AI. Developing new models and algorithms is his expertise together with underlying theoretical analyses. In terms of industries, he has projects in bioinformatics, insurance, transportation, sports and finance. Among other companies, he has collaborated with AllState, Anthem, Baxter, Intel, Stats LLC, United Airlines, American Airlines, Sabre Holdings, FedEx Express, General Motors, and NASA.

Diego Klabjan is a professor at the Northwestern University, Evanston, Illinois, Department of Industrial Engineering and Management Sciences. After obtaining his doctorate from the School of Industrial and Systems Engineering of the Georgia Institute of Technology in 1999 in Algorithms, Combinatorics, and Optimization, in the same year he joined the University of Illinois as an assistant professor in the former department of Mechanical and Industrial Engineering. In summer 2007 he accepted an associate professor tenured position at Northwestern University. In 2012 he was promoted to a full professor at Northwestern University. He is the recipient of the first prize of the 2000 Transportation Science Dissertation Award and the Preseren’s award for the outstanding undergraduate thesis.

He is the Director of the Master of Science in Machine Learning and Data Science and he serves as Director, Center for Deep Learning.

My hypothesis: Gene editing may pose existential threats to humanity—long before the rise of deep-neural-network-based AGI or ASI.
