Biography

Marija Vukomanović (née Jevtić) graduated from the Faculty of Physical Chemistry, University of Belgrade, in 2005 with the thesis entitled “Molecular Mechanics and its Application to Organic Molecules”. In 2006 she started her research career as employee at the Institute of Technical Sciences of the Serbian Academy of Sciences and Arts (ITN SASA) where she was working as a young researcher enrolled in post-graduate studies at the Faculty for Physical Chemistry. In June 2008 she defended master thesis entitled “Sonochemical synthesis and characterization of hydroxyapatite and poly(D,L-lactide-co-glycolide)/hydroxyapatite composite material” at Faculty of Physical Chemistry of University of Belgrade and received title Master of Physicochemical Sciences. After finishing her MSc she started work on her PhD thesis at the Faculty of Physical Chemistry (University of Belgrade) related to the development of novel drug delivery systems. In 2009 she received a scholarship from the Slovene Human Resources Development and Scholarship Fund for the period 2009-2011 and started with her second PhD thesis at the International Postgraduate School of Jožef Stefan Institute related to the development of novel antibacterial agents based on the application of nanoscience and nanotechnology. In March 2011 she defended first doctoral dissertation entitled “Controlled release of an antibiotic from PLGA/HAp nanospheres synthesized in an ultrasonic field” at Faculty of Physical Chemistry of University of Belgrade and received title Doctor of Sciences. In June 2012 she defended second doctoral dissertation entitled “Sonochemical synthesis and characterization of hydroxyapatite/metal-based composite materials for biomedical applications” at International Postgraduate School of Jožef Stefan Institute and received her second title Doctor of Sciences.
Currently she is employed at the Advanced Materials Department of the Jožef Stefan Institute where she is responsible for organization and leading of the scientific research within Biomaterials group. Special emphasis of her work is on development of novel type of antibacterial agents, bioactive materials and smart drug delivery systems. She is responsible for establishment of a novel laboratory equipped for the synthesis, processing, and characterization of biomaterials as well as for investigation of in vitro characteristics of biomaterials and their interactions with bacterial and mammalian cells.
