Chemistry of Materials for engineers and engineering students, 3 credit points, 32 hours, 30+ students. Course is to give an overview about most important materials, that are used in industries and in our everyday lives. Chemical composition and structure and how these affect the properties of various materials. Material groups that are covered are fluids, metals, alloys, ceramics, glass, polymers, coatings, natural building materials, wood and paper, composite materials, nanomaterials, …

2014 – 2022 PhD Student, Tallinn University of Technology, Estonia.

My doctoral research focuses on the applicability of antibacterial and antifungal properties of metal nanoparticles in environmental engineering areas, such as water purification or sustainable construction material protection. Also due to the environmentally friendly application areas, I am developing greener synthesis methods for metal nanoparticle production.


2009 – 2014: MSc in environmental engineering

My education was based on civil engineering curriculum, where I acquired my engineering basis. In addition the specializing was in environmental engineering, where main emphasis was on different materials and their recyclability. My thesis was about ecologically friendly construction material – straw, which should be protected to maintain its intrinsic and healthy properties. I supposed it to be protected by silver nanoparticles, which are cheap to produce, environmentally friendly and recyclable.
