Crystal Ng
Associate professor, group lead

I am a hydrologist/hydrogeologist interested in how shallow groundwater systems interact with vegetation, biogeochemical cycles, and climate in ways that impact society.  I use a combination of computational models and field observations, including statistical approaches that merge the two.  Diverse cultural perspectives further shape my understanding of integrated hydrologic sytems, which have become inextricably tied to human activities. 

 

 

Harsh Anurag

Graduate student (PhD)

I received my Bachelor's and Master's degree in Geology from Indian Insitute of Technology (IIT), Roorkee, India in 2016. I am currently working on an ecohydrological project that evaluates how dynamic vegetation growth impacts groundwater recharge. I am interested in understanding the changes in vegetation-groundwater interaction and how it might affect our ecosystem. I use computer models and statistical data-model fusion techniques to study ecohydrological interactions across a range of spatial and temporal scale. My broader goal is to improve our knowledge of how future changes will impact our water resources.

 

 

Shaoqing Liu

Post-Doc

I received my Ph.D degree from Purdue University, West Lafayette in 2016. My research interest is about improving the quantification of carbon, water fluxes between biosphere and atmosphere by using in-situ observation and process-based ecosystem models. Right now I am working on plant trait based ecohydrology modeling. Outside of work, I enjoy swimming, badminton and fishing.

 

 

Leah Nelson

Graduate student (Masters)

I am a MS student researching tropical glacierized watersheds.  Currently, I am implementing hydrochemical mixing model to identify groundwater pathways on Volcán Cayambe and Chimorazo, Ecuador .  I grew up in Upstate New York, and received my undergraduate degree in geology from Carleton College, in Northfield, Minnesota.  Before coming to the U, I worked in environmental consulting in the San Francisco Bay Area.  Outside of work, I enjoy running, yoga, and being outside.

 

 

 

 

 

Patrick O'Hara

Graduate student (Masters)

I have been implementing a reactive transport model for two-dimensional transects across a perimeter dike surrounding a taconite mine’s tailings basin in NE Minnesota. The models are used to evaluate the reduction and transport of sulfate from the tailings basin, through the perimeter dike, into the surrounding groundwater. Currently, I am conducting metagenomic sequencing of microbial communities sampled from Second Creek, a sulfate-impacted stream also located in NE Minnesota, to determine species responsible for sulfate reduction, iron reduction, and methanogenesis.

 

 

Leila Saberi

Graduate student (PhD)

I completed my master's degree in Civil and Environmental Engineering at the University of Tehran, Iran in 2014. I then received a DAAD Scholarship and spent two years as a research assistant at the GFZ German Research Center for Geosciences (GFZ) in Potsdam, Germany (2014-2016). I am interested in using models and analyzing data to understand the interaction of environmental changes, hydrological cycle, and vegetation. I am currently using a fully coupled, physically-based reactive transport, land-surface, hydrologic model (RT-Flux-PIHM) to predict the ecohydrologic response of tropical glacierized watersheds to climate change. 

 

June Sayers

Graduate student (MS)

I am an MS student in Earth Science - Hydrogeology. I'm half Red Lake Band of Ojibwe and half Ho-Chunk Nation. I am an enrolled member of the Red Lake Band of Ojibwe. I have a Bachelors of Science in Hydrology from St Cloud State University; St. Cloud, MN and Bachelor of General Studies from the University of Idaho; Moscow, ID. I first studied wild rice at an academic level in the winter of 2011 while a Hydrology student at St. Cloud State University. I began working at the University of Minnesota National Lacustrine Core Facility (LacCore) later in 2011 as a lab technician. While at LacCore I had the opportunity to work on a project collaborating with the Minnesota Pollution Control Agency to do a study on sulfate levels of wild rice water bodies. Fast forward to 2020 when the timing for graduate school has been worked out in my life. I am fortunate to be a part of a good group of people on a project that will benefit Indigenous communities.  

Alex Waheed

Graduate student (Masters)

I am an MS student in the UMN Earth and Environmental Sciences Department researching lake geochemistry and hydrogeology as part of the Manoomin wild rice and Grand Challenges Project in Minnesota and the Great Lakes region. I grew up in Chicago, IL and completed my undergraduate degree in geology at Whitman College in Walla Walla, WA. Following graduation, I spent a year working overseas in Malaysia before beginning at the U. Alex's 4 favorite things are: running, listening to podcasts, summer, and cooking Pakistani food.
