The STARS program provides fully funded PhD positions at Charles University, Faculty of Science. Now there are 3 calls related to soil mechanics and groundwater flow open until 11th of March (starting date Oct 2021):
“Experimental and numerical investigation of coupled thermo-hydro-mechanical behaviour of clay with focus to cyclic processes” (David Mašín)
“Non-Newtonian fluid mechanics in porous media in relation to the pore size distribution” (Martin Lanzendörfer)
“Thermo-hydro-chemo-mechanical characterisation of the residual shear strength of an expansive clay” (Gianvito Scaringi)
