Computer scientist and educator with a D.Sc. from the University of São Paulo and a research stay at the Max Planck Institute for Dynamics and Self-Organization. My research bridges bio-inspired neural computing, nonlinear dynamics, and pattern recognition, investigating how biological neuronal mechanisms can inform computational intelligence. With more than a decade of university teaching alongside senior industry practice in software architecture, machine learning, and high-performance computing, I bring research depth and applied engineering experience into the classroom.

Research Interests

DeFi, Smart contracts and decentralized applications
Small-world networks and complex systems
Computation in large-scale systems
Artificial neural networks and deep learning
Nonlinear systems and network dynamics
Synchronization of coupled oscillators
