Born in Naples in 1948, Professor Walter Grassi graduated in Electronic Engineering at the University of Pisa in 1974. After holding various positions as a Professor, Professor Walter Grassi is Professor of Technical Physics Today in the Department of Energy Engineering , systems, land and buildings of the University of Pisa, where he is responsible of the laboratory LOTHAR (LOw gravity and Thermal Advanced Research). Currently Professor Walter Grassi is president Italian Geothermal Union (UGI), a member of the ESF (European Science Foundation) and member of the National Council of Technical Physics.

At the University, Professor Walter Grassi, as well as having been part of the board of the department several times, in the early nineties he was a member of the Integrated Academic Senate for the drafting of the Statute of the University of Pisa, the Board of Directors in the years 1992/94, the academic Senate in the periods 1995/98, 1998/2000 and 2010/2012, and director of the department from 2006 to 2010. He was also energy managers of the University of Pisa and chief of the energy rector.

Professor Walter Grassi has carried out theoretical and experimental research in the field of heat exchange with studies on critical flow phenomenon "pool boiling" and "flow boiling" and ribagnamento of hot surfaces (rewet), subject in both developed function of the safety of nuclear reactors is, subsequently, for the hardening of ferrous materials on behalf of Dalmine SpA
In the field of energetics General, Professor Walter Grassi has collaborated with ENEA doing an analysis of the "bioclimatic" buildings performance with regard to the "energy" and the conditions of comfort and a study for the reorganization of the plants ENEA base in Antarctica. On behalf of SIV (Italian Flat Glass) it analyzed comparatively the energy behavior of light and some types of glass being.
Professor Walter Grassi has coordinated numerous research programs MURST, CNR, the European Union, the Italian Space Agency (ASI), the European Space Agency (ESA). It was also the coordinator of the PRIN "thermal fluid in two-phase media in drips and bubbles for innovative energy applications" and ENEA projects under the framework agreement ENEA-MISE on the definition of evaluation parameters on energy consumption of the hospitals and the construction of application software for the energy audits for residential and tertiary buildings.

Among the positions held, Professor Walter Grassi was responsible for a multi-annual agreement between the Energy Department of the University of Pisa and the Tuscan cooperatives for the realization of campaigns of measurements (temperature, humidity, noise and lighting) for the qualification the energy performance of buildings and well-being. He was also responsible for drawing up the energy plan of the Province of Pisa (on Energy Agency commission Pisana) and drafting the Guidelines for Sustainable Construction of the Municipality of Pisa. Finally until 2004 he was a member of the Tuscan Regional Government Committee for energy management, he has been a member of the Regional Scientific Committee of the Agency for Energy (REA) during the final stage of drafting the energy plan of the Tuscany Region 2000 Pisan Agency board member for energy and 2004-2006 regional Agency President for energy, REA SpA
