Research
Interests
The main focus of my research is to efficiently
manage (access, store, and integrate) large scientific datasets using
quantization based summaries.
My CV
Education
I am a PhD Candidate at The Ohio State University in the Computer Science and Engineering
Department, where I also graduated with a Master’s Degree in Computer
Science.
Currently I am working as a Graduate Research
Associate with Dr. Hakan
Ferhatosmanoglu in the Database
Research Lab.
I graduated with a Bachelor’s degree in
Computer Engineering from the Pontificia
Universidad Católica Madre y Maestra in Dominican Republic.

About me
I was born a few years ago ;) on December 12th,
day of “Our Lady of Guadalupe” in Santo
Domingo, Dominican Republic.
I am happily married to Jose Maria Monestina and we have two beautiful
children: Jose Enrique and Maria Josefa. I spend all my free time with my
family, playing, reading, walking, and travelling. I consider myself an
optimistic person who thinks everything would always work out just fine.
