Dr. Eduardo Arzt

Molecular biologist, obtained his undergraduate Degree of Pharmacologist at the Faculty of Pharmacy and Biochemistry of the University of Buenos Aires (FFyB-UBA). Received his Master in Experimental Biology at the Metropolitan Autonomous University of Mexico, his PhD from the FFyB-UBA at the Lanari Institute of the Faculty of Medicine -UBA, and conducted his Postdoctoral research at the Max Planck Institute of Psychiatry in Munich, Germany.

He is currently a Professor at the Faculty of Exact and Natural Sciences (FCEN) of the University of Buenos Aires (UBA), senior researcher at the National Scientific and Technical Research Council (CONICET) of Argentina, External Scientific Member of the Max Planck Society of German,y and Director of the IBioBA-CONICET-MPSP.

His work has been awarded in multiple occasions with the Guggenheim Fellowship by the John Simon Guggenheim Memorial Foundation, New York, USA; the Bernardo Houssay Award to the best BioMedical Researcher from the National Secretary of Science, Argentina; the Bunge y Born Foundation Award for Outstanding Researcher in Experimental Medicine; the Konex Award; the award to Outstanding Personality of Science granted by the city of Buenos Aires; the Order of Merit of the Federal Republic of Germany; the Berthold Medal-DGE-Germany, and the TWAS Prize, among others.

Throughout his professional career he directed 18 MDs or PhDs thesis and his work (more than 170 papers) was published in different journals such as Cell, Molecular Endocrinology, FASEB, J. Clin. Invest., Endocrinology and Trends Pharmacol Sci. among others. In addition, he participated as invited speaker in more than 150 conferences, workshops and symposia both in Argentina and abroad.

He leads the “Physiopathological impact and molecular mechanisms of inflammatory mediators” and “Neuro-endocrine tumors: cellular and molecular mechanisms” research projects at IBioBA-MPSP.
