Doctoral advisor

Alexandru Cecal (b. July 18, 1940, Cahul, Soviet Moldavia - d. November 1, 2021, Iasi, Romania) was a chemist, professor at the Alexandru Ioan Cuza University of Iași/Romania,[1] known especially for his contributions in the field of radiochemistry.

Education[]

Alexandru Cecal attended the primary school in Pianu, Alba County (1947-1951), continuing his studies (1951-1957)[2] at the Boys' Middle School[3] (former "Mihai Viteazul" Theoretical High School, now "Horia, Closca and Crişan")[4] from Alba Iulia.

Between 1958-1963 he attended the University of Bucharest (Physical chemistry/Radiochemistry). In 1972 he gained his PhD in Chemistry at the Alexandru Ioan Cuza University of Iași, with a thesis entitled "Kinetics of the isotopic exchange reactions in Tl(I) - Tl(III) complexes with different ligands" (supervisor: ).

He fulfilled several postdoctoral appointments in universities and research centers such as Technical University of Munich (group of Hans-Joachim Born), TU Dresden, Forschungszentrum Karlsruhe, Moscow State University (group of Alexander Nesmeyanov), Laval University etc.
