Dr. Ana Kramar was born in Belgrade, Serbia, where she finished her academic studies and obtained PhD in 2015. in the field of technological engineering -textile engineering. During her research career, working on several national and international projects, Ana Kramar investigation interest was focused on cellulose materials, fibers and textiles. During her PhD she was involved in developing chemical and physical methods for cellulose fibers modification in order to prepare cellulose medical materials. Application of various antimicrobials and antioxidants, enzymes, metallic nanoparticles, functional dyes, plant extracts, etc. on the functionalized cellulose enabled not just targeted antimicrobial application but also contributed to better understanding of cellulose chemistry, supramolecular structure of cellulose and structure-property relationship.
She has published more than 20 journal articles and over 40 conference papers.
She is affiliated with UC3M from January 2021 under the framework of CONEX-Plus Program, where she will investigate the advanced techniques for nanofibers and films production, with special attention to polysaccharide materials.
