Graduate Students
Alyssa Valdez
Alyssa Valdez earned a B.S. degree in Earth System Science at UC Merced. During and after undergraduate, she worked in Professor Sora Kim’s stable isotope laboratory, spending time studying shark teeth to learn about their habitats. Alyssa is interested in isotopes, understanding intersections between environmental justice and science, and hopes to contribute to our understanding of greenhouse gas emissions from manure management in California agriculture. Alyssa hails from Fremont, CA, and enjoys cooking and spending time with her dog Miso.
Mariana Reyes
I graduated from UCR in 2021 where I received a bachelor's Degree in Geology in the Earth and Planetary Sciences department. As an undergraduate, I worked on analyzing geophysical data to characterize the lithosphere-atmospheric boundary. During his time I also took various global climate change courses which further interested me to pursue climate change research. In Hopkins Climate Change and Sustainability lab, I am researching Methane emissions from landfills in California. In my free time, I enjoy traveling, working out, and trying new foods.
Michael Rodriguez
Michael earned his B.S. in Environmental Chemistry from UC Davis in 2016. As an undergraduate Michael researched the effects of biochar on nutrient retention in soils and bioremediation of oil-contaminated soils. Michael also researched nitrogen management in wheat using proximal sensing devices and carbon sequestration of Kernza as a Junior Specialist at the UC Davis dept. of Plant Sciences. Currently, Michael is a graduate student in the Hopkins climate change and sustainability lab researching soil GHG emissions from land application of anaerobically digested dairy manure amendments.
Diana Rodriguez Amezquita
Diana graduated in 2017 with an Environmental Engineering from El Bosque University, located in Bogota, Colombia. Upon finishing her undergraduate studies, she worked in the industry of studies required for environmental licensing of different types of projects, such as Roads, Solar Parks, and Eolic Parks. Working with nonconventional renewable energies developed in her a great interest in Climate Change issues. Diana worked in research during her undergrad in the environmental laboratory in which she studied the potential for biofuel from the waste of Coffee production. In her personal life, she enjoys traveling, hiking, and trying new food
Heaven Denham
I received my B.S degree in Environmental Science: Geoscience at the University of Washington Tacoma. As an Undergraduate I researched dry deposition on Spirit Lake at Mount Saint Helens to analyze total nitrogen and phosphorus entering the lake through dry particulate matter. I have also done various research on freshwater quality and was a lab assistant at the Center for Urban Waters in Tacoma, Washington. At the Greenhouse Gasses Lab I am interested in air quality and environmental justice. In my free time I enjoy various artistic hobbies and hiking.
Juliana Guerra
Juliana Guerra completed her B.S. in Environmental Science and Technology from the University of Maryland, College Park in 2023. While at Maryland, she worked in Dr. James Farquhar’s PanoLab, researching methane emissions and sourcing in sewage networks in College Park, Maryland. Through this experience, Juliana became interested in urban greenhouse gas emissions and tracing sources through isotopes and other gases. In the Hopkins Lab, Juliana plans to continue exploring her research interests in urban greenhouse gas apportionment through various projects. During her downtime, Juliana enjoys reading, practicing astrology, caring for her plants, and socializing with friends.

Nidia Rojas Robles, Ph.D.
Dr. Nidia E. Rojas Robles got her Ph.D. in Biotechnology, Instituto Tecnológico de Sonora, Mexico. She has been working with carbon and water fluxes across a successional gradient of tropical dry forest in its northernmost spatial distribution in Mexico. Nidia is originally from Sonora and is involved with the MexFlux network. Currently, Nidia is working on understanding the spatial and temporal patterns of trace gas emissions and source apportionment using isotopes across dairy farms in California. She has published scientific work in English and Spanish. She hopes to contribute to the knowledge of the mechanisms involved in agricultural emissions and subsequently contribute to mitigation strategies. In her free time, she enjoys a good coffee, walks, and a good carne asada in the company of friends and family.
