Nirmala Vasudevan is Associate Professor in the Department of Physics, Amritapuri. She obtained a doctorate in theoretical physics from Northwestern University, USA. Her doctoral thesis titled, “The Phase Transition SUSY SU(5) → SUSY SU(3)×SU(2)×U(1)” examines phase transitions in the early universe in the framework of supersymmetric grand unified theories. After the completion of her PhD, she worked on neutrino phenomenology.

Dr. Nirmala joined Amrita Vishwa Vidyapeetham (Amrita University) in 2006. She became actively involved in India’s first European Commission-funded project for the deployment of a wireless sensor network-based landslide early warning system at the Anthoniar Colony landslide in Munnar, Kerala. The system consists of over 150 sensors installed at different locations and depths; the data are transmitted to the university campus over an aerial distance of approximately 130 km. The system has been functional since 2009, with landslide alerts issued in 2009, 2011, and 2018. Based on this system, the Ministry of Earth Sciences, Government of India, sanctioned a similar deployment at the Chandmari landslide in Gangtok, Sikkim. The system installation was completed in September 2018. In addition to participating in the deployments, Dr. Nirmala has visited over 50 landslides in India in the states of Kerala, Sikkim, Uttarakhand, Mizoram, Andhra Pradesh, Orissa, and Arunachal Pradesh, and is responsible for the geotechnical characterisation of the landslides and hydrological and slope stability modelling.

Additionally, motivated by a desire to help children with learning disabilities, she approached the Amrita Centre for Research in Analytics and Technologies for Education (CREATE) in 2013. She has studied the challenges children face in learning to read and spell in Malayalam. This research was supported by a grant from the Department of Science and Technology-Cognitive Sciences Initiative, Government of India.
