RESEARCH AND WORK INTERESTS

My doctoral dissertation involves filter theory. In this work, I developed theory for applying filtering techniques to a class of non-stationary data called M-stationary processes.  I illustrated these new developments on simulated and real world data.

 

My current research interests revolve around the study of the following fields:

Time series analysis

Filter theory

Wavelets

Statistical computing and simulation

 

Academic teaching

I have obtained widespread teaching experience as an instructor for many courses in both math departments and statistics departments. I can plan, design and teach classes for various audiences. In addition, I look forward to implementing the use of new technology to further the knowledge of my students and encouraging students of different demographic backgrounds to pursue careers in fields involving mathematics.

TEACHING EXPERIENCE

Odessa College, Odessa, TX
Associate Professor, Department of Mathematics 2003-present
I have full responsibility for teaching undergraduate mathematics and statistics courses: preparing notes, holding lectures and office hours, designing and grading exams, and assigning final grades.
Southern Methodist University, Dallas, TX
Instructor, Department of Statistical Science 1999-2000

I had full responsibility for teaching undergraduate statistical courses: preparing notes, holding lectures and office hours, designing and grading exams, coordinating a teaching assistant, and assigning final grades.

University of Puerto Rico, Humacao, PR
Seminar Associate, Summer Institute in Mathematics for Undergraduates 1999

I assisted the seminar leader in teaching and conducting laboratories. The primary goal of the summer seminar was to promote minority interest in graduate mathematical research.

Southern Methodist University, Dallas, TX
Teaching Assistant, Department of Statistical Science 1998-1999

My responsibilities included conducting statistical labs, grading labs and homework, holding office hours and assisting the professor as needed.

Texas Tech University, Lubbock, TX
 Teaching Assistant, Department of Mathematics 1994-1997

I had full responsibility for teaching undergraduate mathematical and statistical courses: preparing notes, holding lectures and office hours, designing and grading quizzes and exams, and assigning final grades.

 

RESEARCH AND CONSULTING EXPERIENCE

Biostatistician, Office of Research and Sponsored Programs 1999-2003, Texas Woman's University, Denton, TX

As the campus biostatistician, I assist faculty with 1) designing their current experiments, 2) writing of proposals to obtain grants, 3) creating databases, 4) analyzing data and 5) submitting statistical results for publication. I also conduct statistical workshops intended to further the knowledge of both faculty members and graduate students.

Summer Intern, Semiconductor Products Sector 1997 & 1998, Motorola, Austin, TX

As a summer intern, I worked with engineers in many departments designing experiments, performing quality control and modeling data.

Research Assistant, Department of Civil Engineering Summer 1996, Texas Tech University, Lubbock, TX

I modeled skid resistance data for the Department of Civil Engineering and the Texas Department of Transportation.
