C. P. Rajendran is an Indian geoscientist known for his wide-ranging research activities across geological and geophysical sciences His research broadly focuses on geodynamics and tectonics with an emphasis on the earthquake source zones of India. After completing his bachelor’s at the Trivandrum University College, he took his post-graduation and doctoral degrees from the Cochin University of Science and Technology. Rajendran began his career in the Centre for Earth Science Studies, as a research scientist and took his doctorate from the Cochin University. After obtaining a Ph.D., he left for the University of South Carolina (USA) for postdoctoral work. On receiving the Ramanujan Fellowship, he was hosted in the Indian Institute of Science (IISc) and later in the Jawaharlal Nehru Centre for Advanced Scientific Research. He has several awards to his credit including the National Geoscience Award. Currently, he is an adjunct professor at the National Institute of Advanced Studies. Kusala Rajendran is an Indian seismologist who has worked extensively on Indian earthquakes. Kusala completed her bachelor’s at the St.Teresa’s College, Kochi, and M.Tech (Applied Geophysics) from IIT, Roorkee. She did her Ph.D. from the University of South Carolina, USA. After her return to India, she got involved in understanding the source properties of the earthquakes along the plate boundaries, including the Himalaya and the Andaman-Sumatra. She has also collaborated with C.P. Rajendran, her spouse on active tectonics and paleoseismology.  After a stint in the Centre for Earth Sciences, Trivandrum joined as faculty at the Center for Earth Sciences (IISc) and taught both at graduate and undergraduate levels, and supervised Ph.D. candidates. She has received several awards including the first National Award for Women Scientist instituted by the Ministry of Earth Sciences, Government of India.
