I´ve been a teacher and researcher for 27 years, since I got my B.Sc. in Computer Science and Mathematics, from the University of Havana, Cuba. I got a PhD. in Mathematics as well, from the Cuban Academy of Science.

I have taught basic and higher math classes to students in high school, undergraduate, and graduate levels, enrolled in many different majors: Business Management, Engineering, Mathematics, Computer Science and Physics.

My students have always appreciated the patience that I have to explain once and again the subject matter.

The many years of experience as a researcher and a teacher at different Colleges, Universities and Research institutions, in different countries and communities, has made me got a wide background of techniques for teaching a variety of population. Besides, it has made me learn the most updated educational developments and technologies.

I use the computer as the technical support to my classes. I make research on recent materials that can improve teaching. My classes are always changing from one course to the other as I get new and better techniques and ways to present the subject.

Computer Programming

I graduated from the University of Havana and have a B.Sc. in Computer Science and Mathematics. I have been a researcher in applied mathematics for more than 20 years. I have participated in many research projects that involved real-world applications that implied implementation, testing and parameter adjustments of numerical algorithms, using mainly FORTRAN and MATLAB.
I have a lot of publications which I have written using different editors: Word, Scientific Word, etc. I have presented my scientific results using PowerPoint.
As a teacher. I have used Excel for recording my students' grades and also I have taught a subject in the MBA program based upon the use of EXCEL for the practical implementation of Business Models.

Discrete Math

I have been a teacher of Calculus I through IV, Linear Algebra, Finite Mathematics, Intermediate Algebra, College Algebra and Trigonometry, Developmental Mathematics, Quantitative Methods for Decision Making, Numerical Optimization; at both, undergraduate and graduate levels. I am also a researcher in the field of numerical optimization methods, with 30 years of experience and a vast record of publications and applications of algorithms and development and implementation of computer codes to real-life problems.


I have a PH.D in Mathematics from the Cuban Academy of Science, thus I'm quite capable of teaching scientific programming (FORTRAN is used specifically for this kind of programming) together with the mathematics that helps to make most optimized program codes.
