PH.D. IN PHYSICS & TECH LEAD

Dr. Jefferson Vaca-Santana

Ph.D. in Physics | Mathematical Modeling, Process Automation & Generative AI

Scientist focused on solving complex systems. I apply the analytical rigor of theoretical physics and cosmology to design data architectures, build intelligent agents (LangGraph), deploy robust workflow automations (n8n), and integrate business intelligence dashboards (Power BI).

About Me

I am a Physicist and Ph.D. in Physical Sciences (Degree obtained in December 2025). My career has developed at the intersection of the **mathematical modeling of complex systems** (with applications in cosmology and affine gravity) and **process engineering based on technology and artificial intelligence**.

I combine a strong foundation in exact sciences with practical skills in data science, computational modeling, and LLM-agent orchestration for business workflows. Additionally, I have pedagogical training oriented towards higher education in STEM subjects and physics-mathematics.

"Physics teaches us to understand the fundamental principles of complex systems; technology allows us to optimize them."

— Dr. Jefferson Vaca Santana
