I am professor of mathematics that work at the Faculty of Geodesy University of Zagreb as lecture. My areas of scientific and professional interest are the application of mathematics in other sciences (chemistry, crystallography, physics, geodesy and geomagnetism). Further, I am the co-author of the mathematics textbook for elementary school (from 5th to 8th grade), and the book Geometry Sketches - Perspective - Monge's Procedure - Axonometry, Geometry of Nature. Actively participates in the activities of the Teaching Section of the Croatian Mathematical Society in organizing and implementing methodical workshops for students and teachers on the popularization of mathematics as well as the application of technology in teaching mathematics, and in a series of projects: Mathematics with the help of computers and the Sketchpad computer program (2007 - 2010. ) organized by the Croatian Mathematical Society and CARNET as one of the coordinators, Geopotential and Geodynamics of the Adriatic (Geo ++Adria) (since 2007), Joint Croatian - Hungarian Geomagnetic Repeat Station Survey and Joint Geomagnetic Field Model (since 2009), Dynamic Number in the organization of the National Science Foundation, U.S.A. and KCP Technologies (from June 2010), IPAQ project – V. gimnazija and PMF Further development and implementation of the Croatian Qualifications Framework (from June 2013 – February 2015) and Mathematical Scientific Challenges_Večer Matematike – HMD (since June 2013), since September 2021, participates in the work of the Mathematical Educator Project.
