About Me
I am an Associate Professor and researcher in the Faculty of Basic and Biomedical Sciences at
Universidad Simón Bolívar in San José de Cúcuta - Colombia.
I am an Associate Researcher at Colombia's Ministry of Science, Technology, and Innovation.
I am also a Scientific Modeling and Business Innovation Research Group (GIMCINE) member.
My research interests revolve around applied mathematical modeling and mathematics education.
My CV and academic background is as
follows:
Research
My research interests focus on mathematical modeling, pattern recognition, and mathematics education. I am dedicated to exploring how
mathematical models can be used to understand and predict complex systems. Also, I focus on leveraging neural networks and other advanced
techniques to improve data analysis and decision-making processes. Additionally, I am passionate about enhancing the teaching and
learning of mathematics, focusing on methodologies that make mathematical concepts more accessible and engaging. Below is a list of the
projects in which I have participated.
- 2022-2025: Mathematical Modeling on Parallel and Distributed Computing based on Extreme Learning Machine using Large-Scale
Databases I am the principal investigator of this project, which aims to develop a training method using OS-ELM (Online
Sequential Extreme Learning Machine) neural networks for large-scale database classification problems. The objective is to achieve a
runtime performance superior to current state-of-the-art methods by employing a mathematical model based on a distributed system.
This approach is designed to enhance efficiency and scalability in processing extensive datasets. The project is funded by the ANID
(National Agency for Research and Developmen) Chile / Scholarship Program / BECAS DOCTORADO NACIONAL / 2020–21201000.
