Near Surface Geophysics Lab

About Us           

             Near surface geophysics is the use of geophysical methods to understand the phenomenon in the shallow subsurface of the Earth. The various methods include gravity, magnetic, electric, electromagnetic, and seismic refraction and reflection. These methods can be applied to multiple areas such as environmental contamination problems, groundwater resources, archaeological research and mapping glacial drift thickness.  

             Our work involves theoretical modeling and field work utilizing various state-of-the-art instruments to address complex challenges through innovative methods. Advancements in technology has opened the possibility for the use of Unmanned Aerial Vehicles (UAV) in changing the operating environment for the instruments. Our laboratory is developing methods for magnetic and VLF systems in conjunction with UAVs to increase field work efficiency.

              We are located in Rood Hall, home of the Department of Geological and Environmental Sciences at Western Michigan University. A field geophysical test site is located on WMU Asylum Lake property and has been extensively used since installations began in 1995.

Chanho Park
Ph.D. Student in Geophysics
Chanho joins after graduating with a BSc. in Geology from Calvin College. His first project involved cemetery lot assessment for a local township in Jackson, MI using GPR. As a Ph.D. student, his interests are in aerial application of geophysical methods using Unmanned Aerial Vehicles. Currently, he is developing methods for airborne VLF system with applications to landfill leachate monitoring.

Aylin Yildirim
Ph.D. Student in Geophysics
Aylin is a Ph.D. student in the Geosciences department. She graduated from Istanbul Technical University (ITU) in Turkey with a BSc. in Geophysical Engineering and a MSc. degree in Geographical Information Technologies. She worked as a Research Engineer at ITU CSCRS (Center for Satellite Communications and Remote Sensing) and completed her master's thesis in "Soil Salinity Monitoring vis Remotely Sensed Data" project. Her interests are in remote sensing and geophysical application on the near-earth surface. In her free time, Aylin loves to travel and find out more about different cultures. She also loves to hike and explore the nature.

Nazife Onaral
M.S. Student in Geophysics
Naz is a graduate student in geophysics pursuing a master’s degree. She graduated from Istanbul Technical University (ITU) in Turkey with a B.S. in Geological Engineering.  Currently, her research is focused on exploring plant-root-soil interaction using GPR and Electrical Resistivity Tomography. She is proficient in Matlab, AutoCAD, Surfer and COMSOL.
