Computer scientist specializing in bio-inspired neural computing, computational complexity and dynamics, pattern recognition, small-world theory, and banking knowledge. With a focus on understanding the foundations of human computation, I investigate biological neuronal approaches to replicate processing behaviors in computational intelligence.

In the realm of programming, I bring a strong background in highly complex domains, including modeling, software architecture, artificial intelligence, machine learning, deep learning, computer vision, cryptography, and high-performance computing, among others.

Research Interests

Computational for large-scale systems
Machine learning and artificial neural networks
Nonlinear systems and dynamics networks
Synchronization of coupled oscillators
