Mathematics PhD and educator, designing problem-based lessons for exam success and research-grade analysis.
ColombiaWhat I'm looking for
I’m a PhD in Mathematics (Universität Zürich) and I combine rigorous research thinking with practical teaching. I like turning complex ideas into clear, problem-solving approaches that help learners build confidence.
Since Jan 2025, I’ve been an Exam Preparation Teacher with Grupo Educativo Cinco, teaching a course for high schoolers preparing for the state exam (equivalent of SATs). I design lessons around solving problems from previous exams and adjust how I explain concepts based on student responses.
Earlier, I worked as a Research Assistant at Universidad del Norte, where I reviewed classic sources and state-of-the-art papers. I performed computations in abstract algebra and produced written documents summarizing relevant literature and results.
My academic work includes studying abstract algebraic structures and their relation to knots, along with supporting courses as a teaching assistant. I also continue developing my technical toolkit through Google Data Analytics, Machine Learning, Deep Learning, and a freeCodeCamp developer certification.
