Postdoctoral Fellows
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.
Dr. Sandra Armengol Vall
I am a Postdoctoral Scholar at the Department of Environmental Sciences, University of California Riverside. My research is aimed at gaining knowledge and understanding in the use of chemical and isotopic tracers in hydrogeology. My main areas of expertise include the use of conventional chemical techniques, geochemical modelling and geostatistics to identify the groundwater provenance in aquifers and to study water-soil interactions including salinization processes.
I have five years of experience in analyzing groundwater chemistry and collecting rainwater samples. I worked in groundwater related issues in Spain (Onyar River Basin, Llobregat River Basin) and North (Iberá Estuary) and Central (Matanza-Riachuelo River Basin) Argentina. I have planned and conducted many surveys, including building a rainwater monitoring network for a 2300 km2 basin.
Dr. Lin Chen
Co-advised by Dr. Jirka Šimunek and Dr. Scott Bradford
Lin Chen is a postdoctoral researcher at the Department of Environmental Sciences, working with Dr. Jirka Šimunek, Dr. Scott Bradford, and Dr. Hoori Ajami. Lin’s post-doc research is to develop a watershed scale model to simulate the coupling of water flow and contaminant transport in surface water, vadose zone, and groundwater. Lin completed his PhD at the University of Montreal, where he utilized a combination of field work and numerical modeling to quantify the surface energy components for different land cover types and to investigate impacts of subsurface water flow on the thermal stability of roads and highways built on permafrost.
Graduate Students
Alyssa Duro
Co-advised by Dr. Daniel Hirmas
Alyssa earned her BS in Environmental Sciences from the University of California, Riverside in 2020, then continued her studies at UCR as a PhD student in pedology. Her dissertation work aims to quantitatively and objectively describe the spatial distribution of soil properties using multi stripe laser triangulation, proximally-sensed hyperspectral imaging, and high resolution photography in order to understand the mechanisms underlying soil structure and related soil functions including carbon storage and hydraulic properties.
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. My project was focused on understanding the response of perennial grass-legume intercropping to soil health parameters. 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.
