Ramiro Barrantes-Reynolds

Ramiro Barrantes-Reynolds, PhD - Statistician (Curriculum Vitae)


Ramiro, a native of Costa Rica, graduated with a double major in Computer Science and pure Mathematics from the University of Costa Rica, and then decided to try to find the meaning of life in a Zen Buddhist center in Shelburne, Vermont. Eventually he started working as a bioinformatics programmer which led to a PhD doing Bayesian Statistics as part of the Cell and Molecular Biology Program at the University of Vermont. During that time, he completely fell in love with statistics and  learned a lot more about molecular biology, statistics and bioinformatics, and about the use of quantitative/computational methods in research.
