Overview

The geo-group performs multidisciplinary research in the areas of geotechnical and geoenvironmental engineering, as well as on geophysics and geomaterials.

Prof. Chrysochoou performs research on

  • Site remediation
  • Heavy metal speciation and mobility
  • Chemical soil stabilization
  • Brownfield redevelopment
  • Industrial waste recycling

Prof. Liu‘s research interest are:

  • Near-surface and Subsurface imaging through geophysical (seismic, acoustic, electric, and radar) surveys for engineering and environmental purposes
  • Modeling wave propagation through finite difference and finite element methods
  • Battlefield environment and unattended ground sensor network
  • Geophysical detection of fluid flow in fractured rocks 
  • Earthquake strong ground motion site effect assessment.

Infrastructure

1. Geophysics Lab

The Geophysics Laboratory is located in room 114A of the F.L. Castleman building.  The geophysics lab houses a variety of field and laboratory testing equipment including ground penetrating radar (GPR), electrical resistivity (ER), seismic reflection and refraction, Induced Polarization (IP), Time-domain Reflectometry (TDR) and a HP Network Analyzer.

2. Geoenvironmental Lab

rs-marisa2

The Geoenvironmental Laboratory is located in room 105 of the F.L. Castleman building. We have 500 ft2 all to ourselves, plus a 1,000 ft2 space that houses all major equipment shared by the ENVE faculty.

The GEO lab has everything you need to play: fume hood, DI water supply, oven, multi-meters for pH, Eh, DO, bromide and sulfide measurements, spectrophotometer, micronizing mill, rotary agitator, multi-channel column setup, hot plates, chemicals, etc.  

3. Advanced Geotechnical Lab

The Advanced Geotechnical Laboratory is located in room 112 of the F.L. Castleman building.  The Advanced Geotechnical lab is a soils testing lab with capabilities of testing a wide variety of soil samples with an array of triaxial testing equipment, resonant column testing, and ultrasonic testing module.

Research Sponsors

The Geo3 group performs research on diverse projects funded from the Department of Homeland Security, Environmental Protection Agency, U.S. Geological Survey, CT Department of Economic and Community Development and National Science Foundation.
