Efobo Oghenevwede is a first year Hydrogeology graduate student from Nigeria. He attended Delta State University Abraka, Nigeria, where he earned his bachelor’s degree in Geology. He has worked as a Geologist at Morgan-T Associates and DSR Investment Ltd with duties which include groundwater monitoring and sampling for EIA projects, supervision of borehole drilling, well installation, and sampling of surface water, groundwater, and soils. His research interest is on surface water-groundwater interactions. 

Cavien Satia


I graduated from University of New Hampshire in 2020 with a BS in Earth Science focusing on Geology. I am continuing my Graduate career at Illinois State University in Hydrogeology MS program. I am interested in learning and doing research on remote sensing analysis on surface water color (e.g., rivers, lakes) and its relationship with climate change. I like to play and watch football (or they call it soccer in the US), and also I love to hike in different National Parks and gaming.

Okiemute Commander


I am Okiemute Commander. A first year student in the Hydrogeology program. I am from Delta State, Nigeria. I have a Bachelor's degree in Geology from Delta State University Abraka. I have previously interned at the Ministry of Water resources, Bayelsa State as an Assistant hydrogeologist. My research will focus mainly on groundwater quality and groundwater contamination.

Hey I'm Jake Riedel! I'm a second year in the hydrogeology master's program, am interested in Karst (underground caves), and am hoping to go on towards a PhD program studying Hydrogeophysics. I am from Buffalo, New York and received my BS in geology from the University at Buffalo. I have two cats that barely get along: Mango and Naomi, love music, film, camping, and fishing. GO BILLS!

Eumi Hong


Eumi Hong ("Elisa")  is a first-year graduate student. Earned a B.S. degree in geology from Oklahoma State university with a minor in mathematics and geography.

Primarily interested in groundwater and the extraction of groundwater, along with water management. Random hobbies include sewing, watercolors, and games.

Olaoluwa David Oladuji


Olaoluwa David Oladuji is a first-year graduate student in Hydrogeology , I am from Southwestern Nigeria, I completed my bachelor's degree in Geology from Ekiti State University Ado-Ekiti Nigeria, I am a First year Teaching Assistant , my research interest lies broadly in Hydrogeology and my research will be focusing on variables driving Nitrates trends in some major Illinois watersheds. 

Alhassan Sahad (Head Rock Wizard)


Alhassan is a second year Hydrogeology graduate student from Ghana. He attended Kwame Nkrumah University of Science and Technology in Ghana where he obtained BSc. Geological Engineering. His undergraduate research was on how the Geotechnical characteristics of lateritic base materials change with time when loads are applied to them. Alhassan also worked as a student intern at B.Ali Geo Consult where he took part in the Geophysical Exploration for groundwater, supervision of borehole drilling, pumping tests, and water quality analysis. He is currently doing research on the use of a tracer test to determine the fate and transport of nitrate in a saturated buffer zone.

Mike Sell (Head Rock Wizard)


Mike Sell is a second-year hydrogeology graduate student from Park Ridge, IL. He completed his undergraduate degree and received a B.A. in Geology at Augustana College in Rock Island, IL. His interests in geology consist of extraction of natural resources, water management, and mineral exploration. Currently, his thesis research is utilizing 3-D geologic modeling to test storage of sequestered CO2 in an aquifer.

Savannah Thielbar


Hi! I am Savannah Thielbar from Seymour, Wisconsin. I recently graduated from Saint Norbert College in De Pere, Wisconsin with a Bachelor’s of Science degree in Geology. I am currently a Master student here at Illinois State University specializing in Hydrogeology. I love to be outdoors and enjoy spending time with my dog Remmington. I hope to continue to grow my skills and passions into a career that I will love and appreciate. I look forward to teaching others about geology all while diving into some fun research. If you see me around campus be sure to say hello!
