Ştefan I. Gheorghiţă graduated from the Bucharest Polytechnic as a mechanical engineer in 1950. He then joined as a faculty member the Department of Applied Mathematics and Physics of Bucharest University, where he submitted a PhD thesis in fluid mechanics in 1955 under the tutorship of Caius Iacob (1912-1992). Gheorghiţă then continued as a Reader until 1968, when being appointed applied mechanics professor of his University, thereby being responsible for fluid mechanics and elasticity.

\

Between 1952 and 1978 Gheorghiţă published some 120 papers in applied mechanics. He thereby became a specialist in groundwater hydraulics with a particular interest in the description of a porous medium from the mathematical point of view. He also contributed to the mixing problems in groundwater hydraulics under unsteady flow conditions. Other topics were the mixed groundwater and free surface flow problems. He applied solution methods including the semi-inverse and the semi-indirect approaches, and the mathematical formulation in a complex domain. His books written between 1957 and 1978 include Porous media, Subterranean hydromechanics, an Introduction on porous flow models and Boundary layer flow theory. He was elected to the Academy of Sciences of the Romanian Socialist Republic, and was an Editorial Board Member of the Romanian Journal of Mathematical and Physical Sciences, and of the Mathematical Forum published in India. He was further awarded the 1966 Gh. Lazăr Premium from the Romanian Academy of Sciences.
