Research Profile:

The planet Earth is our home, and as home, our desire should be taking care of it (I have just made a huge hopeful assumption). We are part of nature, and I believe that before interacting with the environment, we need to consider consequences of our actions. We need a healthy planet to live; we depend on it. The planet does not need healthy (nor sick) humans to exist. However, humans forget the mist in space and time that we represent and, instead, focus on our own physiological and artificial needs without having any mercy on our Earth.

With the growing human population comes increasing demand for resources, resulting in an ever increasing need for energy. Consequently, the myriad of portable electronic devices and battery/hybrid electric vehicles presents a developing challenge for the growing demand of energy storage, requiring new materials and novel approaches. Metal oxide engineered nanomaterials (MO-ENMs) have broad applications in energy storage and emerging fuel cell technologies. However, the production and application of ENMs will lead to inevitable environmental release during all life cycle phases; manufacturing, delivery, use, and disposal. Environmental concentrations of most ENMs are unknown, but exposure modeling studies suggest soil as the major sink. ENM impacts are underesearched leading to a growing concern regarding immediate and long term effects.

My research interests develop, attempting to understand how anthropogenic compounds affect the world invisible to the naked eye yet responsible for the basis of life: microorganisms and their communities!

About Me:

 Helena Avila-Arias About Me Picture

I decided to jump into this Ph.D. journey primarily because I love research and was 100% convinced that I wanted to be a professor.

My passion for research is intact. The discovery process from identifying a gap of knowledge through analyzing the ‘weirdness’ of the results is just fascinating!

My passion for teaching is present as well. I believe we are all students and teachers every day, not only within an academic institution. Inspiring and being inspired is a daily experience!

Meeting people in the name of science (including traveling!) is one exciting part of being a scientist in which I very much enjoy! Interacting and sharing experiences with researchers within and outside your field is so enriching; seeing the same topic through different lenses is an awing experience!

ESE has allowed me to do exactly that; it has helped open my mind (and ears) to interdisciplinary approaches across many topics. We are a community that looks forward to solving problems and improving situations. Sharing with eyes from different backgrounds has been absolutely beneficial to my growth and success thus far.
