Nato Jorjiashvili was Born on October 14, 1977, in Tbilisi. She entered the Tbilisi State University Faculty of Applied Mathematics and Computer Science in 1993, where she graduated with honors in 1998 and was awarded a bachelor’s degree in Applied Mathematics. In the same year, he entered the same Faculty Master stage, which she also graduated with honors in 2000 and obtained the Master’s degree in Applied Mathematics. Along the same university in 1999 and began to work on the theory of random processes as an Assistant. In 2004 she defended her PhD thesis in the field of mathematical cybernetics. Since 2004, she has been working initially at the Seismology at the Institute of Geophysics and the Seismic Monitoring Center. At the same time, in 2005, she went to Japan for a Master’s course in seismology and earthquake engineering at Building Research Institute, and in 2006 was awarded by Master’s degree in disaster mitigation. She is actively involved in scientific research in seismology, both domestically and in international projects. International underwent training in France and Japan. She also has participated in many international conferences and forums. Since 2008 she has worked at Ilia State University as an Assistant Professor; from 2020, she holds the position of Associated Professor. She is an author of 35 scientific publications in highly-rated international journals.
