I am interested in poroelastic behavior of rocks, multiphase fluid flow in rock, and geomechanical modeling.  I am currently pursuing applications of fiber-optic and hydrostatic-level sensors to monitoring deformation and temperature in underground laboratories and mines with experiments in the Sanford Underground Research Laboratory (SURF) in the former Homestake gold mine in the Black Hills of South Dakota, Fermilab, Conco-Lafarge Mine, and the Earthquake Research Institute of the University of Tokyo.  I am also involved in poroelastic modeling of Brady’s Hot Springs, a geothermal field in Nevada.  Professor Dante Fratta of Geological Engineering, Dr. Jim Volk of Fermilab, and Professor Tomochika Tokunaga of the University of Tokyo are collaborators in the underground lab research.  The geothermal research team is led by Professor Nick Davatzes (Temple University) and Professor Kurt Feigl.
