I'm identifying myself as a combination of a researcher and a salesperson. As a researcher, I worked in the pulp and paper technology field and investigated various cardboard recycling methods. Later, I studied solid-liquid separation processes and tested vacuum, pressure and polishing filters. The most essential part of my doctoral studies was investigating the performance-related characteristics of woven filter media, such as air permeability, liquid permeability and pore size (distribution). During my studies, I also worked as a Salesperson and consulted customers about coffee machines. This experience improved my communication skills, ability and willingness to listen, maintain focus, and find the best solution for the customer's needs. This mixture of education, experience and practice has shaped me and my life path. If you need more information, please don't hesitate to contact me via marina.angesleva@gmail.com
