I am in PhD and I use LaTex from 8 years ago. Before, I have worked in graph theory in bioinformatics and now my PhD is in geomatic but always with graph. So, LaTex is very useful for people like me in a scientific context, for my PhD and for my teaching.
I hope you will understand my english in my future posts, because I am french and I know, my english is not so good

Best,
GDM
