Graduate Students
Elizabeth Occhi
B.S. Chemical Engineering (minor in Chemistry), University of Iowa, 2021 M.S. Geosciences, University of Iowa, in progress Liz's research is focused on assessing groundwater/surface water exchange and subsurface transport of pharmaceuticals and pesticides in a stream in Iowa where total discharge is dominated by effluent from a waste water treatment plant. Shubhamita Das
B.S. Geology, Kazi Nazrul University, 2018 M.S. Geology, Indian Institute of Engineering Science and Technology, 2020 Ph.D. Geoscience, University of Iowa, in progress Shubhamita's research is broadly focused on advancing methods for delineating hydrostratigraphic units and improving their representation in numerical models of groundwater flow. Currently, Shubhamita's is conducting research to improve our understanding of the the relationship between sequence stratigraphic units and hydrostratigraphic units in fractured sedimentary rock aquifer systems and using high frequency transient hydraulic head data sets to improve delineation of hydrostratigraphic units in heterogeneous unconsolidated sediments. Sophie Pierce
B.A. Environmental Sciences, Minor in Geographic Information Science and Spanish, University of Iowa, 2014 M.S. Geoscience, University of Iowa, in progress Sophie’s current research aims to quantify variability of hydraulic conductivity in highly heterogenous ice-marginal sediments at a contaminated site in Wisconsin using different methods at a variety of measurement scales. |
Undergraduate Students
Emma Holesinger
B.S. Geoscience, University of Iowa, In Progress Emma's current research is focused on collecting high resolution hydraulic head profiles at high temporal frequency from existing boreholes monitoring the Cretaceous Dakota aquifer system in Kansas and Iowa. These data sets will be utilized to improve our understanding of aquifer/aquitard units in the Cretaceous and determine locations for future coring and multilevel installations. Maximilian Collins
B.S. Geoscience, University of Iowa, In Progress Max's is researching geologic controls on the degree of confinement in a shallow aquifer using transient hydraulic head data sets from conventional wells and multilevel systems. Henry Frederick
B.S. Geoscience, University of Iowa, In Progress Henry is interested in applying hydrogeologic concepts to better understand current environmental problems. Ultimately to aid in the best use of remediation techniques. |
Past Team Members
Samantha Fiegen
B.S. Environmental Engineering, University of Iowa, In Progress Samantha's research project is focused on using data from grain size analysis to estimate hydraulic conductivity for Quaternary materials from sites in Wisconsin, Minnesota, and Iowa. Zach Vig
B.S. Physics, B.S. Geosciences, University of Iowa, 2023 Currently a PhD student studying planetary science at the University of Maryland Zach used grain size analysis and hydraulic conductivity estimates to better define the hydrogeologic facies for an ice-marginal depositional environment at a contaminated site in Cottage Grove, Wisconsin. Thomas Doyle
B.S. Environmental Science, Iowa State University, 2020 M.S. Geoscience, University of Iowa, 2020-2022 Currently an Environmental Specialist with the City of Marion Thomas studied the hydrostratigraphy of the Silurian-Devonian aquifer in Eastern Iowa. His research combined the use of multilevel measurements from FLUTe liners and borehole geophysics to improve the understanding of the aquifer. Riley Kniptash
B.S. Environmental Science, University of Iowa, 2019 M.S. Geoscience, University of Iowa, 2020-2022 Currently a geologist for Barr Engineering Riley used tools commonly used in contaminant hydrogeology investigations to characterize water and iron exchange between a glacial aquifer and a ferruginous (iron-rich) lake. The results of Riley's study are being used to improve the iron balance for the lake needed to support biogeochemical cycling studies. Kris Symanski
B.S. Geoscience (minor in Environmental Science), University of Iowa, 2022 Currently a graduate student at NC State Kris's research focused on preliminary estimates of groundwater discharge rates and directions through the loess and alluvial aquifer materials at our new outdoor hydrogeology teaching field site. |
