Mario Franca held academic positions as Research and Teaching Associate at the EPFL, as Assistant Professor at the New University of Lisbon and at the University of Coimbra (Portugal), and as Senior Member of the Marine and Environmental Sciences Centre (Portugal). He served in many instances as consultant in hydraulic engineering and he was head of the hydraulics department in an engineering company, having participated and directed applied projects on dams, hydropower, water supply, river engineering, drainage, mining sites, emergency planning and safety of hydraulic infrastructures. He has served and serves in several faculty commissions, in Lisbon and Lausanne, and was involved in a MOOC on Fluvial Hydraulics.
Mário's research focus on river hydraulics; turbulent processes in open channel flows; fluvial geomorphology and morphodynamics; density currents; and non-conventional hydropower production in supply networks. Recently he is interested also on socio-hydrology and on the global impact of hydraulic natural and built structures. He is author of several scientific publications and regularly gives invited research seminars in these fields of research.
