Short summary of activities and expertiseI gained my BSc degree in Chemical Engineering with an excellent award in 2014, and my MSc in Engineering in Polymer and Fiber Technology with the highest-honors classification award in 2016 at the Budapest University of Technology and Economics. In 2016 I conducted research for six months and gained professional experience at Singapore’s lead public sector R&D agency. A full range of responsibilities related to this project were given to me, from the experiments' statistical design to measurements and evaluation. I started my Ph.D. in 2016 at the George A. Olah Doctoral School of Chemistry and Chemical Technology Ph.D. Program in Chemical Engineering. I will defend my doctoral thesis this year. My Ph.D. research focuses on the structure-properties relationships of semicrystalline polymers and the simulation of properties based on the parameters of the crystalline structure. I worked with polyolefins as model materials, mainly with different types of neat and nucleated polypropylene, but I have practical experience with other polymers as well. I also have practical experience with different processing technologies and sample preparation techniques. I am also interested in polymer identification and characterization methods. I supervised three BSc and six MSc students and managed their research. I was responsible for holding laboratory practices, i.e., Rheology, Microscopy, Infrared spectroscopy of polymers, Thermal characterization of polymers. I was also responsible for instrument training and maintenance. I managed several diverse industrial projects and collaborations related to the techniques mentioned above on various samples and products. I am the first author of six published papers in peer-reviewed journals. I co-author one book chapter and five other publications in peer-reviewed journals. During my career, I gained different honors and awards. I have a share in two filed Hungarian patents and a filed international patent.
