About Me

I will be a fifth-year graduate teaching assistant and doctoral candidate for the Mathematics Department at the University of Nebraska-Lincoln (UNL) starting in August 2022. For more information, please refer to my CV. I was born and raised in Scottsbluff, Nebraska, and I graduated from Scottsbluff High School in 2014. I attended UNL Math Day throughout high school, and it was my senior-year trip to Math Day that inspired me to study math at UNL. I am also fluent in Spanish since my parents are from Peru. 

In 2012, I got to visit Machu Picchu: the Lost City of the Incas.


I am currently working on research in the area of mathematical biology. A lot of my research has been focused on mathematically analyzing the population dynamics in herbivore-plant models. The analysis includes items such as the application of stability theory and investigating parameter bifurcations.  I have also used and/or written up MATLAB programs that assist with the graphical (nullclines and phase portraits) and numerical (parameter combinations) analysis of these ecological models. My advisors are Richard Rebarber and Brigitte Tenhumberg.

Teaching & Educational Services

I will be serving as a thesis mentor to math teachers involved in UNL's Masters of Arts for Teachers (MAT) program during summer 2022. My key duty is to review the thesis paper for three groups (of three) teachers pursuing their MAT degree in mathematics. 

I was the associate convener for the UNL Math Resource Center (MRC) during the 2020-2021 academic year. I have also collaborated on the development of an OER Calculus Textbook during the summer of 2019, and I have assisted with the development of curriculum and learning material for the following math courses taught at UNL: MATH 102 (Trigonometry), MATH 104 (Applied Calculus), MATH 106 (Calculus I), and MATH 435 (Math in the City).

Here is a list of the most recent math courses I have taught (or was a teaching assistant for) at UNL:

  • MATH 435 - spring 2022
  • MATH 102* - spring 2022
  • MATH 435 - fall 2021
  • MATH 221 (Differential Equations Recitation) - fall 2021
  • MATH 810T (Algebra for Algebra Teachers) - summer 2021**
  • MATH 104* - spring 2021**
  • MATH 101* (College Algebra) - fall 2020**
  • MATH 104*  - summer 2020**
  • MATH 101* - spring 2020**
  • MATH 101* - fall 2019
  • MATH 107 (Calculus II Recitation) - spring 2019
  • MATH 106 (Calculus I Recitation) - fall 2018

NOTE:   * denotes that I was the instructor of record for that course, and  **  denotes that the course was taught online via Zoom (or had a mixture of in-person and remote learning).

If you are a student of mine in any of the courses listed above, please consult with Canvas for additional course information.


My hobbies outside of mathematics are going on walks, hanging out with friends, playing board/card games, bowling, dining at restaurants, and travelling. I am also a dedicated fan of the Nebraska Cornhuskers (GO BIG RED!), and I have gone to almost every home football game at Memorial Stadium since fall 2014. 

The Greatest Fan in all of College Football!

Fun fact: this picture is from the 2018 Nebraska vs. Akron game which ended up getting cancelled due to stormy weather.
