Albert C.J. Luo. Albert C.J. Luo is a mechanical science, physics, and applied mathematics researcher who has been serving as a distinguished research professor at Southern Illinois University Edwardsville in Illinois since 1998.

Luo is an internationally recognized scientist in the field of nonlinear dynamics and mechanics.  His principal research interests lie in the field of Hamiltonian chaos, nonlinear mechanics, and discontinuous dynamical systems.

Early life and education 
Luo received a Bachelor of Engineering in mechanical engineering from the Sichuan University of Science and Engineering in 1984, a Master of Engineering in engineering mechanics from the Dalian University of Technology in 1990, and a Doctor of Philosophy in applied mechanics from the University of Manitoba in Canada in 1996.

From 1996 to 1998, he was an NSERC (National Science and Engineering Research Council of Canada) postdoctoral fellow at the University of California, Berkeley.

Career 
Since 1998, Luo has worked at Southern Illinois University Edwardsville as an assistant/associate/full/distinguished research professor.

Dr Luo developed stability and bifurcation theory in nonlinear dynamical systems, and he also established the theoretical frames of discontinuous dynamical systems for many applications in science and engineering, and he developed analytical techniques that is very efficient to achieve periodic motions to chaos analytically. Since the 18th century, one has extensively used techniques such as perturbation methods to obtain approximate analytical solutions of periodic motions in nonlinear systems. Towards analytical chaos in nonlinear systems systematically presents an analytical approach to determine periodic flows to chaos or quasi-periodic flows in nonlinear dynamical systems with/without time-delay. The presented analytical techniques provide a better understanding of regularity and complexity of periodic motions to chaos in nonlinear dynamical systems. Dr Luo developed a dynamical system synchronization theory based on the local singularity theory of discontinuous dynamical systems. Dr. Luo developed the implicit mapping dynamics for semi-analytical solutions of periodic motions to chaos in nonlinear systems, which are from symbolic dynamics to mapping dynamics in nonlinear dynamical systems. Further, one can measure chaos determinatistically instead of stochastically. The quadratic dynamical systems presented by Dr. Luo provides a way to solve the Hilbert's 16th problems. Such a theory presents the bifurcations of the 1-dimensional flows in nonlinear dynamical systems. The infinite-equilibriums are the switching bifurcations of the two sets of equilibriums. Techniques can be implemented and applied to science and engineering.

His major contributions on nonlinear dynamical systems are:

 A theory for stochastic and resonant layers in nonlinear Hamiltonian systems
 A local theory and singularity for discontinuous dynamical systems
 Flow barriers theory for discontinuous dynamical systems
 Synchronization of continuous dynamical systems under specific constraints
 Synchronization and companion of discrete dynamical systems
 Analytical solutions of periodic motions to chaos in nonlinear systems
 Discretization and implicit mapping dynamics in nonlinear dynamical systems
 Analytical periodic flows to chaos in time-delay systems
 Semi-analytical solutions of periodic motions to chaos in nonlinear systems
 Infinite homoclinic orbits in 3-D nonlinear systems (Lorenz and Rosller systems)
 Memorized nonlinear dynamical systems and time-delay
 Two-diemnsional quadratic dynamical systems
 Two-dimensional cubic dynamisl Systems

In addition, Luo developed accurate theories for nonlinear deformable-body dynamics, machine tool dynamics and others:
 
 An approximate plate theory
 A theory for soft structures
 A nonlinear theory for beams and rods
 Fluid-induced nonlinear structural vibration
 A large damage theory for anisotropic materials
 A generalized fractal theory

He has published over 400 peer-reviewed journal and conference papers.  Luo was an editor for the Journal Communications in Nonlinear Science and Numerical simulation, and  Luo is editors for the book series on Nonlinear Systems and Complexity (Springer), and Nonlinear Physical Science (Higher Education Press).
