Roman Makhnenko is an assistant professor in the Department of Civil and Environmental Engineering at the University of Illinois at Urbana-Champaign. Roman received his undergraduate degree in mechanics and applied mathematics at Lomonosov Moscow State University, Russia, in 2007. He then obtained his MS (2009) and PhD (2013) degrees in geological and civil engineering from the University of Minnesota - Twin Cities. From 2013 to 2016, Dr. Makhnenko worked as a postdoctoral researcher and lecturer at the Swiss Federal Institute of Technology in Lausanne (EPFL, Switzerland) on the project related to assessment of geological storage of CO2. Currently, Roman is developing a rock mechanics program at Illinois that would involve modern high-pressure high-temperature rock testing facilities and new graduate and undergraduate courses on the topic.

Research Statement

Prof. Makhnenko's research area is experimental geomechanics and development of novel methods in laboratory characterization of fluid-saturated geomaterials with applications to deep carbon dioxide (CO2) and nuclear waste storage, geothermal energy exploration, gas shales, and hydraulic fracturing.

Graduate Research Opportunities

- improvement of geomechanical measurements for deep CO2 storage

- thermo-poro-visco-elasticity of shales

- predicting fracturing of rock: from micro to macro level

- assessment of shallow and deep geothermal energy extraction

Undergraduate Research Opportunities

- 3D rock failure criteria

- understanding size effect on fracture propagation

Research Interests

  • Rock-fluid interaction: poroelasticity, thermo-poro-visco-elasticity, plasticity, permeability
  • Fracturing of rock: size effect, process zone, hydraulic fracturing, failure criteria, induced seismicity
  • Geo-energy applications: deep CO2 storage, nuclear waste storage, gas shales, geothermal energy
  • Novel testing methods for geomaterials: optical, ultrasonic, X-ray CT, acoustic emission
