Education

Bachelors in Chemical Engineering from Universidad Nacional de Colombia

Career Experience

I'm a chemical engineer and working in modeling and automatic control of processes. I work as a researcher developing innovative projects, making real the advances from science to industry. Being part of the academic community, I have the opportunity to teach in universities and faculties. Transmission of knowledge is the key to guarantee the continuous improving of human beings and our society. With the academics, you not only learn about concepts and theories, but how to be a curious person, to think by yourself and to help others to become the best version of themselves.

I Love Tutoring Because

it is a great chance to demonstrate that our differences in culture, location and language are not drawbacks to building a better future and to helping to each other. Besides, by teaching, I learn each day something new about myself and about the things I believe I know already.
