Short Bio

Dr. Premalatha K received her M.Sc. degree in Physics from Bharathiar University, Coimbatore, in 2012 and completed her doctoral degree at Bharathidasan University, Triruchirappalli, in July, 2018. She was awarded National Post Doctoral Fellowship by DST-SERB, Government of India for the period from 17.03.2019 to 16.09.2021. She was also awarded Post Doctoral Fellowship by UGC, Government of India at Bharathair University, Coimbatore, from 25.10.2021 to 24.10.2024. Her research aims in analyzing the emergence of complex patterns in certain coupled nonlinear oscillators. Acting as a reviewer in the international journals “Chaos: An Interdisciplinary Journal of Nonlinear Science” and “European journal of Physics Plus”.
