Vlad Hasmatuchi was born in December 1983 in Arad, Romania. In 2007, he graduated at the Faculty of Mechanical Engineering, Hydraulic Machinery Branch from “Politehnica” University of Timisoara (UPT), Romania. In the same year, Vlad Hasmatuchi joined the Laboratory for Hydraulic Machines (LMH) from the École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, to achieve a doctoral work in the field of hydraulic turbomachinery. In 2012, he got his Doctoral Degree in Engineering from the EPFL, Switzerland, with the Thesis entitled “Hydrodynamics of a Pump-Turbine Operating at Off-Design Conditions in Generating Mode”.

During his studies, he had the opportunity to gain research work experience at the National Center for Engineering of Systems with Complex Fluids - Numerical Simulation and Parallel Computing Laboratory from UPT, Romania. His Diploma Project entitled “The Analysis of the Effect of Water Jet Injection on the Flow Behavior in a Francis Turbine Draft Tube at a Part Load Operating Point” was performed at the EPFL-LMH, Switzerland.

In 2012, Vlad Hasmatuchi is joining the University of Applied Sciences Western Switzerland in Sion, the Systems Engineering Institute. He is in charge mainly of experimental investigations, as well as of numerical simulations.

His main research interests are the hydrodynamics of turbines, pumps and pump-turbines, including design and evaluation of the performance of hydraulic machines using the experimental investigation, as well as the numerical simulation.
