PhD in Science

My industrial experience working at the South African company Tongaat Hulett allowed me to develop mathematical models which solved complex and challenging problems by predicting the behavior of system variables through statistical analysis, thereby determining trends and relationships between variables. My interdisciplinary qualifications provide me with the tools for applying different methodologies to optimize and control diverse processes through to use of a wide range of modern statistical techniques such as optimization, machine learning, time series forecasting, clustering or dimensionality reduction methods. I also have experience teaching Mathematics, Physics, Thermodynamics and heat transfer at the university level. I spent more than ten years in formal education training in programs such as Matlab, Homer Energy, R, Python, Spark, SQL, and Maple. These tools bring me mathematical rigour to help guide decision-making based on data analysis. These are some examples of the development of projects in Matlab and Python. I have knowledge of NumPy, Scipy, Matplotlib and Pandas Python libraries for data analysis. I am interested in solving real problems using my programming and math skills, cognitive and problem-solving capacity.

Experience

Researcher

Acao Covid
May 2020 - Dec 2021 (1 year, 7 months)
We investigated the different trends in the simulation results, identifying the behavioral change threshold positions, i.e., the curve’s inflexion points. The model was calibrated using immunity surveys. We designed and built statistical models on time series data and pattern recognition We created mathematical models, which brought the analytical rigor to help guide data-driven decision making.

Researcher

Universidade de Sao Paulo
Aug 2014 - Mar 2019 (4 years, 7 months)
Assessed quantitative models through computational programs written in Matlab, where diverses variables were identified and monitored Performed statistical inference and data visualization of the main variables and their correlations Conducted independent research utilizing large data sets, numerical algorithms and implementation of high-performance computing solutions at industrial scale

Researcher

Researcher at the National Pedagogic University Center of research
Feb 2009 - Dec 2010 (1 year, 10 months)
Magnetohydrodynamics and Dynamo Theory were used to build mathematical models which predicted and explained the characteristics of the solar magnetic field. Performed a comparative analysis between the models built with a computational program in C++ Used optimization methods, hypothesis testing, and uncertainty quantification solved complex and challenging problems by predicting the behavior of system variables
