Arbetsuppgifter

Doktorand vid institutionen sedan januari 2002. Undervisar i ingenjörsgelogiska tillämpningar.

Forskningsinriktning och aktuella projekt

Studerar fintätning av sprickigt berg med tyngdpunkt på ett nytt kiselbaserat injekteringsmedel. De första studierna visar att denna produkt har god inträngnings- och tätningsförmåga. Projektet avser att skapa förståelse för produktens lämplighet och användbarhet som fintätningsmedel. Projektet ingår i KK-stiftelsens forskarskola och delfinansieras av Eka Chemicals, BESAB, Vägverket och SBUF.
