Biographical Info

Personal Statement

A few years ago, when I was in my junior year of high school, my dad received a job offer to relocate from Mexico to Saint Louis, Missouri, this was a huge opportunity for our family and he told us that we would move. When I arrived to the United States, it was an experience that marked my life for the reason that it was a tough challenge to adapt to a new culture, a new language, and a new life. I overcame this hardship and took advantage of the benefits it presented. This led me to challenge myself in different ways including reading very intensively during my spare time, which changed my way of thinking and viewing things. I discovered that physics was a passion I had, as well as solar energy and renewable energy sources in general, and I confirmed that I wanted to be an engineer and contribute with innovation to improve the world and the society we are all part of.

I decided to attend New Mexico State University, where I have further challenged myself. I am currently a sophomore studying Civil Engineering with an emphasis in Structures and a dual minor in Mathematics and Economics. After my first semester I received the opportunity to collaborate with Dr. David Jauregui, Department Head of Civil Engineering, in a consulting project for the New Mexico Department of Transportation were we have evaluated bridge load rating. Dr. Brad Weldon, Assistant Professor, has been my mentor in research through New Mexico AMP on Recycled Concrete Aggregates. This research has been my interest because the world supply of virgin aggregates is declining and by analyzing the performance of recycled aggregates costs can be minimized and in the future infrastructure can be maintained with recycled aggregates. This would avoid depletion of virgin aggregates and reduce environmental impact. As a side project I have been part of Studio G, a student business accelerator at NMSU, were I have received mentorship to develop a new business as well as many resources and funding to continue business research.

After receiving my Bachelors of Science in Civil Engineering, I plan to attend graduate school and pursue a master’s degree in structural engineering as well as an MBA and hopefully be able to start a company with the goal of contributing to a cleaner and more sustainable future.



Sustainable Concrete Structures using Recycled Concrete Aggregate: Short-Term and Long-Term Behavior Considering Material Variability

As the world’s infrastructure grows, so does the depletion of one of earth’s natural resources, virgin aggregate. As a nonrenewable source, the implications of depleting the existing reserves in close vicinity of civil infrastructure come with significant consequences. With coarse aggregate taking up around 40%-50% by volume of concrete mix, researchers have been attentive on the possible use of recycled concrete aggregates (RCA) in place of virgin material for structural applications. Using RCA in structural applications greatly depends on its ability to demonstrate sufficient strength, stiffness, and durability. Using experimental results, prediction equations have been developed to estimate a RCA mixtures performance before a mixture has even been made. By simplifying the inputs into the equation, industry professionals should be able to use it in their own operation.
