I am an Environmental scientist committed to taking care of this planet through research and education. My work focuses on generating insights for understanding, predicting, managing, and mitigating pollution in both natural and urban environments through the study and application of Microbiology.

My academic journey has comprised a Bachelor of Science in Chemical Biology from UNAM, Mexico, followed by a Master of Science in Environmental Engineering and a Doctorate in Environmental Science (integrated), both earned at Newcastle University, UK. Additionally, I have undertaken research visits to esteemed institutions across the globe, including Canada's University of Alberta (2010), Sweden's Chalmers University of Technology (2018), the UK's Marine Biological Association (2020), and Viet Nam's Phenikaa University (2022). These diverse professional and personal experiences, including a memorable encounter with Sir David Attenborough, have shaped my work, fostering a transdisciplinary approach.

My projects integrate knowledge and techniques from Environmental and Applied Microbiology, Molecular Biology, Analytical Chemistry, and Environmental Engineering. Specifically, my research questions are directed towards “little things” of enormous importance. For instance:

1. Investigating the relationships between microorganisms and the processes that they mediate,
2. the impacts of pollutants in the environment, and
3. the interplay between anthropogenic inputs and microorganisms.

Additionally, I am deeply committed to science communication, finding joy in teaching and embracing the role of a lifelong learner.

I am in awe of this planet and always curious about it, hence choosing to dedicate my career to its care. I enjoy good food (vegetarian) and a cup of tea (or several). I relax practicing yoga, I love running, and find multi-day walks to be revitalising. I’m always excited about traveling, dancing, and chatting with friends.
