Professor Grebogi is a leading expert in nonlinear and complex dynamics, with research spanning chaotic dynamics, fractal geometry, systems biology, neurodynamics, fluid advection, relativistic quantum chaos, and nanosystems. His work has profoundly influenced the understanding and control of chaotic systems, most notably through the OGY method for chaos control. He has pioneered research in strange nonchaotic attractors, multistability, and dynamical transitions in complex systems.

The recent publications highlight a strong trend toward interdisciplinary applications, integrating nonlinear dynamics with machine learning, neuroscience, biomedical engineering, and quantum systems. His team applies advanced mathematical frameworks to real-world problems such as motor imagery recognition, brain dynamics in mental disorders, fatigue detection, and quantum scarring. The integration of data-driven methods with classical dynamical systems theory underscores a modern, hybrid approach to complexity science.
