Lee’s group is focused on exploring the unusual chemistry of transition metal complexes using advanced computational approaches, aiming to accelerate the discovery of next-generation transition-metal catalysts and materials. Transition-metal molecules and materials possess unique electronic and magnetic properties that can vary significantly depending on their environment, offering immense potential for a wide range of applications in chemistry. Such dramatic changes result from a quantum chemical phenomenon known as strong electronic correlation. Thus, there is an urgent need for theoretical and computational tools that can simulate real-world transition-metal molecules and materials. Motivated by this challenge, our research team is focused on advancing many-body electronic structure methods to simulate the complex systems, utilizing both classical and quantum computing devices.
