Vaishnavi Varikuti

Co-advised by Dr. Daniel Hirmas

I earned my BS degree in Agricultural Sciences from Acharya N.G. Ranga Agricultural University, India. After graduation, I was highly aspired to study abroad and thus joined South Dakota State University, Brookings to get my MS degree in Plant Sciences. As a PhD student at Texas Tech University under the supervision of Drs. Daniel Hirmas and Hoori Ajami, my research is focused on understanding the effects of interactions between roots, soil, and bedrock on the evolution of soil hydraulic properties, distribution of soil chemical and physical properties, and hydrological functioning of the critical zone.

Eric Wineteer

As an Environmental Sciences PhD student at UC Riverside, I use remotely sensed data to constrain hydrologic models and better understand groundwater recharge. In my previous position as a consulting engineer, I developed improved statistical downscaling techniques to predict the impact of climate change on water quality, and its implications for infrastructure planning. I have extensive experience in high performance computing, particularly in parallel programming with Python. I recived my B.S. in Civil Engineering and my M.S. in Environmental Engineering from the Northeastern University. 

Undergraduate Students

juan.jpg

Dr. Juan S. Acero Triana

Dr. Acero Triana completed his PhD in Ag & Bio Engineering with a concentration in Computational Science and Engineering at UIUC (US) and an MSc in Applied Hydrometeorology at RSHU (RU). He joined the Department of Environmental Sciences in 2020, where his research studies ecohydrological processes across highly managed agroecosystems and lake-watershed interactions integrating numerical models and data analytics tools. The ultimate goal of his research is to develop robust decision support systems that help decision-makers and stakeholders to assess management alternatives aimed at enhancing watershed ecosystem services under climate and land-use change scenarios.

Lily.jpeg

Lily Caplon-Guin

Lily is an undergraduate student pursuing a bachelor's degree in Bioengineering. She is currently working in Python to analyze USGS well data to quantify groundwater dynamics in the Central Valley. She has previous research experience working in an Entomology lab studying population and community ecology of alpine freshwater habitats where she sorted and identified freshwater invertebrates. Lily hopes to pursue a career relating to research in agricultural sciences in the future.

Dr. Lin Chen 

Postdoctoral Fellow (2021-2024) - Co-advised by Dr. Jirka Simunek and Dr. Scott Bradford

Now: Research Scientist at Northwest Institute of Eco-Environment and Resources, China

Matt.jpeg

Dr. Matthew Amato

Dr. Matthew Amato earned his PhD and MS degrees in Environmental Science from Rutgers University before joining UCR as a postdoctoral researcher. Dr. Amato specializes in applying statistical and numerical modeling techniques to study ecohydrological processes in Earth’s critical zone. His current research integrates data from soil-climate networks and remote sensing products to explore how plants and climate jointly influence soil structure and its impact on the hydrological cycle. The overarching goal of his research is to refine the physical and spatial representation of soil-plant-climate interactions in land surface models, and ultimately to improve forecasts of global environmental change.

Dr. Sakiur Rahman 

Co-advised by Dr. Jirka Šimunek and Dr. Scott Bradford

Dr. Sakiur Rahman, is a postdoctoral researcher, working with Dr. Jirka Šimunek, Dr. Scott Bradford, and Dr. Hoori Ajami at the Department of Environmental Sciences, at UCR. His research is focused on developing a new computationally efficient integrated watershed simulation code. Sakiur earned his PhD from Kumamoto University and worked as a postdoctoral researcher at the RIKEN Center for Computational Sciences in Japan. His research also involves applications of stochastic, data assimilation and Artificial Intelligence (AI) approaches for modeling of hydrological processes. His focus is to create a robust, hybrid modeling framework by integrating AI, numerical models, and isotopes to enhance the understanding and forecasting of hydrological processes.
