 Hi, this is Rajit from India, Fulyev guys are doing well, so let me first introduce myself. I did my PhD from the University of Calcutta in India, so this is the eastern part of India. Then after doing my PhD, I went to the University of Tokyo at the Arthquake Research Institute for my postdoctoral studies and now I am in India. So by training I am a structural geologist and structural is a very important subject, not because of it helps you develop a process based understanding of the natural process of the things you see in the nature. For example, during my PhD, my topic was to understand the mountain building processes in the Himalayas. So for that I went to the field, I observed many structures, I did a mythological mapping, I developed many cross sections, geological cross sections to understand the geometrical relationship within different mythological limits. As a structural geologist, you also need to understand many other things like fracture orientations, like where the faults are there, what is the orientation of the faults etc. And it helps you, if you want to build a road or if you want to build a dam in the mountains or somewhere, you need to understand the structure of that area. It helps you make the right decisions like where to cut the mountains to be in the road, where to build and where do you, also like you know that in the Himalayas or in many mountain areas there are slope failures like those kind of things can get very dangerous. So you need to understand how to cut the road so that the slope failures like there are some, so those kind of incidents don't happen or if you build a dam somewhere, so those dams don't collapse. So structural is a very important subject and basically what we try to understand is the behavior of the rock. From an engineering material science perspective, you will understand that the behavior of any material will change depending on the ambient pressure, temperature, stress condition etc. And it is called rheology in geological or the material science term. And I try to understand the rheology of different geological materials at different patient temperature foundations. So for that, I did some experimental modeling like analog and numerical modeling during my PhD. And after doing my PhD, I went to the Arctical Research Institute to do experiment at the high pressure temperature condition. So if you go deep in the earth like several hundred like close to seven tens of kilometers and you try to understand how a material will behave at that depth, you need to carry out experiments at the high pressure temperature condition. So that then structurally become more like a material science. So it is more similar to an engineering subject or a material science subject or a ceramic science subject. In a natural way, you develop a physics of the process based understanding of what you see in the nature. Thanks for having me and good luck for your studies.
