👋 Hello, I'm Ferney!

Although interested in Mathematics, during my freshman year I failed my first Pre-Calculus exam. At the time I lived and worked with my parents in the Colombia countryside, and I had just graduated from a rural public school with a basic education. With much dedication and overcoming several challenges, I was able to improve my grades significantly and I obtained my BS degree in pure Mathematics.

Throughout my Master of Science in Mathematics (Statistics Option) at the University of Puerto Rico, Mayagüez campus (UPRM), I developed many skills, among which I want to highlight the teaching of Pre-Calculus I and Statistics classes, in addition to academic initiatives to support freshmen under CRRSAA grants.

My academic path

📖 My research

During the fall of 2021, I participated in an educational research initiative, our research group included professors from Puerto Rico, Switzerland, and UK. The investigation ended with a publication in the journal ZDM of Springer. Other results of this research group were published with Dr. Akveld in the VSMP Bulletin journal, and with Dr. Cáceres in the Espacio Matemático journal.

My most recent research is with the Dr. Macchiavelli, who is a professor of Biometry at the UPRM. We are currently studying regression models for censored zero-inflated count data. We proposed new likelihood equations in matrix form for parameters estimation in the censored zero-inflated Poisson regression model. Additionally, we verified the behavior of the MLE through a rigorous simulation study and presented a novel application using a data set of students from the University of Puerto Rico. We are in the process of publishing these results within the coming months.

 Projects

I am part of the team Olimpiadas Matemáticas de Puerto Rico (OMPR) program, which aims to popularize mathematics in Puerto Rico while identifying and nurturing mathematical talent among students.

OMPR plays a vital role in selecting and training students to represent Puerto Rico in International Mathematical Olympiads.
