Wavelets and Fractals in Earth System Sciences

The subject of wavelet analysis and fractal analysis is fast developing and has drawn a great deal of attention in varied disciplines of science and engineering. Over the past couple of decades, wavelets, multiresolution, and multifractal analyses have been formalized into a thorough mathematical framework and have found a variety of applications w

Dr. E. Chandrasekhar is currently an Associate Professor of Geophysics at Department of Earth Sciences, IIT Bombay, Powai, Mumbai, India. After completing M.Sc (Tech) in Geophysics from Osmania University, Hyderabad, India, he joined Indian Institute of Geomagnetism (IIG), in Mumbai, as a researcher. While serving at IIG, he completed his Ph.D in Physics from University of Mumbai in 1999. Later he accepted the prestigious JSPS postdoctoral fellowship and worked at Kyoto University, Japan, during 2000-2002.

He was awarded the visiting scientist position by CNPq of Brazil, and worked at Observatorio Nacional, Rio de Janeiro, Brazil, during 2003-04, before joining IIT Bombay as a faculty in 2004. He was awarded the DAAD short term visiting fellowship to visit GFZ, Potsdam, Germany in 2010. His research interests are: Geophysical signal processing, Geoelectromagnetic induction studies, and Geomagnetism.
