Narayan Bose is a final year Ph.D. student at the Indian Institute of Technology Bombay, where he did his M.Sc. in Applied Geology (2013). He received B.Sc. (Honors) in Geology from the Presidency College (Kolkata) in 2011 and secured 2nd rank in this program under the University of Calcutta. He is specialized in structural geological fieldworks and micro-structural studies especially related to ductile- and brittle shear zones. As a Teaching Assistant, he has been conducting structural geology fieldworks and practical classes for the Masters programmes in Applied Geology, Applied Geophysics and Petroleum Geoscience. He has also reviewed several manuscripts submitted in international journals, and has published a paper in the International Journal of Earth Sciences (Springer). Soumyajit Mukherjee is a professor in the Department of Earth Sciences at the Indian Institute of Technology Bombay, India. He received his PhD in geology and MTech in applied geology from IIT Roorkee in 2007 and 2002, respectively, and received his BSc in geology from Presidency College (Kolkata) in 1999. He was a recipient of the Hutchison Young Scientist Award from IUGS in 2004. He served as the guest researcher at the Hans Ramberg Tectonic Lab, Uppsala University, from 2005 to 2006. Dr. Mukherjee, a structural geologist and tectonician, has performed fieldwork, microstructural studies, and analogue and analytical modeling, mainly on ductile shear kinematics and collisional tectonics. His research and editorial experience spans 15 years and so far he has authored and coedited 14 books and thematic volumes.
