Prof. Alejandro Sosnik received his Pharmacy degree from the Faculty of Pharmacy and Biochemistry of the University of Buenos Aires in 1994, carrying out his professional stage in the pharmacy of a public hospital and volunteering afterwards in the pharmacy of a public pediatric hospital in Buenos Aires for more than one year. During his undergraduate studies, he was also teaching assistant in analytical chemistry and organic chemistry. After two years as junior research scholar of the University of Buenos Aires in the field of organic chemistry (1993-5), he worked as research pharmacist in the Department of Chemistry of the Argentine regulatory agency (equivalent to the US-FDA), a dependency of the Ministry of Health of Argentina (1996). In early 1997, he emigrated to Israel where after obtaining the pharmacist license, he continued his graduate studies, receiving M.Sc. (equivalency, 1998) and Ph.D. degrees in applied chemistry (polymeric biomaterials) from the Casali Institute of Applied Chemistry (The Hebrew University of Jerusalem, Israel, 2003) under the supervision of Prof. Daniel Cohn. In 2003-6, Prof. Sosnik spent a postdoctoral in the laboratory of Professor Michael Sefton (Institute of Chemical Engineering and Applied Chemistry/Institute of Biomaterials and Biomedical Engineering, University of Toronto, Canada) working in the development of hybrid matrices for cell culture and tissue engineering. Between 2006 and 2013, Prof. Sosnik was Assistant Professor (tenure) of Pharmaceutical Technology at the Faculty of Pharmacy and Biochemistry (University of Buenos Aires) and Investigator of the National Science Research Council of Argentina (CONICET, tenure). In this period, he established a research group that worked at the interface of drug crystallization and processing, biomaterials science, nanotechnology and microtechnology, drug delivery and therapeutics. In this context, he supervised three junior staff scientists (CONICET), five postdocs (CONICET) and four Ph.D. theses at the Faculty of Pharmacy and Biochemistry of the University of Buenos Aires. Prof. Sosnik established the “Ibero-American Network of New Materials for the Design of Advanced Drug Delivery Systems in Diseases of High Socioeconomic Impact” (RIMADEL) of the CYTED Program that gathered eleven research groups and companies of Spain, Portugal, Mexico, Cuba, Colombia, Brazil and Argentina and over 75 scientists and served as its international coordinator in the period 2011-2013. He also served as advisor of several Argentine pharmaceutical companies in scientific, technical and intellectual property issues. Owing to its multidisciplinary background and expertise at the interface of drug research and development and polymeric biomaterials, in 2014, Prof. Sosnik was appointed Associate Professor of the Department of Materials Science and Engineering of Technion-Israel Institute of Technology where he founded the Laboratory of Pharmaceutical Nanomaterials Science and heads the BSc program in Materials Engineering and Biology. In the last years, he was awarded the Marie Reintegration Grant of the European Commission for the period 2014-2018 and other competitive Israeli and European research grants and awards. In 2020, he was promoted to the rank of Professor. His current research lines comprise drug self-assembly and crystallization phenomena and processing, polymer and macromolecular chemistry, biomaterials science, colloidal chemistry (drug and polymer self-assembly), hybrid organic-inorganic nanomaterials, mucoadhesive drug delivery systems, nanomedicine (drug encapsulation, release and targeting), therapy of poverty-related diseases (HIV, tuberculosis), pediatric cancer, intestinal diseases and pharmacokinetics (oral, inhalatory and intranasal administration routes) and ceramic/polymer nanomaterials for sono-dynamic therapy. He has served and serves as evaluator for more than twenty national and international research funding agencies and universities. Prof. Sosnik is co-author of over 160 peer-reviewed articles, reviews, editorials and book chapters in areas of biomaterials science, nanomaterials, tissue engineering, pharmaceutical research and development and innovation, drug delivery, co-inventor in several patents and patent applications related to biomedical and pharmaceutical innovation and editor of two books.

Pharmaceutical Materials Science emerged as the systematic study of the physicochemical properties and the behavior of materials of pharmaceutical interest (MPIs) in relation to product performance, MPIs comprising drugs and non-pharmacologically active pharmaceutical excipients. In this framework, the thorough study of the relationship between the structure and the properties of drugs, excipients and their combinations has become a pillar of the rational development of pharmaceutical products.

I am interested in the investigation of novel biomaterials-based strategies to optimize the treatment of disease from the isolation, processing and characterization of pure drugs and the design, production and characterization of polymeric micro and nanocarriers to the evaluation of the performance in relevant in vitro (cell), ex vivo (animal tissue) and in vivo (animal) models. This perspective is articulated and consolidated by the establishment of strategic intra and extramural scientific collaborations. The deep understanding of the relationship between micro/nanostructure, properties and processing methods is a fundamental goal of our research. The main research topics are the following:
