Dr Carlos Grattoni

Profile

Carlos studied Chemical Engineering and Reservoir Engineering in Argentina before joining the National Research Council (CONICET). In 1990 he moved to the UK to study at Imperial College London, where he was awarded a PhD. He spent 12 years in the Petroleum Engineering Group at Imperial College, mostly working in projects sponsored by oil industry, EPSRC, and EU, and managed the Petroleum Engineering Research Laboratory for five years. In 2006 Carlos moved to Leeds and joined Rock Deformation Research Ltd to set up and develop the Sorby Multiphase Flow Laboratory (now part of the Wolfson Lab). In 2012 he joined for the School of Earth and Environment.Carlos has been actively involved in research for over 35 years and has written over one hundred and fifty papers.
