Dr. Seung Jae Lee is an Assistant Professor joined the Department of Civil and Environmental
Engineering at FIU in the Fall of 2014 after completing his Ph.D. in Civil Engineering with
emphasis on Computational Geomechanics at the University of Illinois at Urbana-Champaign.
Dr. Lee works at the interface of Structural, Geotechnical and Computational Engineering and his
research has particularly focused on the complex behavior of geologic materials such as soil, rock
and concrete, aiming to provide (a) a systematic multiscale approach for enhanced engineering
scale prediction based on micromechanical modeling and (b) novel discrete element methods
for advanced micromechanical simulation to overcome computational challenges while keeping
simulation fidelity. A major effort resulted in the development of impulse-based Discrete Element
Method (iDEM) inspired by the real-time methods for computer-animated films and video games.
At FIU, Dr. Lee continues his research to tackle the fundamental mechanisms encoded at the grain
scale to understand how the micromechanical origin governs the complex macroscopic behavior,
but his interest also lies in expanding the research into general discrete mechanical systems and
structural engineering problems concerned with a discrete nature at some scale, aiming to enhance
predictive capabilities in the civil engineering applications.
Dr. Lee has extensively collaborated with external research institutes such as NASA, FRA
and NCSA on various research projects. He contributed to developing a good number of civil
engineering software, and also received several awards for his work from computational engineering
communities including Engineering Mechanics Institute of ASCE.
