Dr. Behara Seshadri Daya Sagar (in short B. S. Daya Sagar) was born in Eluru, Andhra Pradesh, India. He stood first in his Master of Science degree programme, and secured his Ph.D degree from Faculty of Engineering of Andhra University in 1994. His monograph entitled Qualitative models of certain discrete natural features of drainage environment published by Allied Publishers Limited. He is presently working as an Associate Professor Systems Science and Informatics Unit (SSIU), Indian Statistical Institute-Bangalore Centre. Before joining here, he worked as Associate Professor at Multimedia University-Malaysia (2001-07), and as a Research Scientist in Centre for Remote Imaging Sensing and Processing, The National University of Singapore (1998-2001). Before moving to NUS, he held various research positions starting his research career as a Project Fellow (1991-92), CSIR- Senior Research Fellow (1992-94), Research Associate (1995), DST Young Scientist/Principal Investigator (1996-97), and again as Research Associate in (1998).
His primary interests include applications of mathematical morphology, fractals, multifractals, and 1-D maps to deal with various aspects of geomorphic and geophysical phenomena as well as Geographical Information Science. To deal with these studies, he has used nonlinear mathematical morphological concepts to understand the spatio-temporal dynamics in discrete space; and fractals, multifractals and 1-D maps to characterize and quantify the heterogeneities in spatio-temporal dynamics in discrete space. His interests also include the usage of multiscale and multi-temporal digital elevation models derived from various remotely sensed data to extract complex topological information further to characterize these features and to quantify the degree of heterogeneities which are of interest to geomorphologists and geophysicists. He is also involved in applying fractals and non-linear transformations to generate fractal graphics/fractal landscapes, and watershed algorithms for map based hydrological modeling. The applications of the research works, where he is involved, can be foreseen in the fields of simulation and modeling of various surface processes, analysis of remotely sensed satellite digital data and digital elevation models, geocomputation, and spatial analysis. His recent interests include modeling and simulation of lake dynamical behavior in a lattice space. Under his supervision, SIX doctoral degrees and TWO MEngSc (by research) degrees have been awarded.
He has over 65 scientific publications to his credit in renowned international journals, which are indexed in Institute for Scientific Information. His research results have been published in various international journals such as Journal Geophysical Research-Solid Earth, Journal Geophysical Research-Atmospheres, Geophysical Research Letters, Water Resources Research, Nonlinear Processes in Geophysics, IEEE Geoscience and Remote Sensing Letters, IEEE Signal Processing Letters, IEEE Transactions on Power Delivery, Signal Processing, IEEE Transactions on Image Processing, Chaos Solitons & Fractals, Computers & Geoscience, Current Science, Discrete Dynamics in Nature and Society, Fractals, International Journal of Remote Sensing, and Journal Mathematical Geoscience. He has been an invited editor for special issues of Journal Mathematical Geology (in memory of the Late Professor SVLN Rao), International Journal of Pattern Recognition and Artificial Intelligence (Quantitative Image Morpphology), Chaos Solitons & Fractals (Fractals in Geophysics), I.E.E.E Geoscience and Remote Sensing Letters (Surficial Mapping) which are released in 2003, 2004, 2005. He has recently edited along with Prof. Jean Serra a special issue on Spatial Information Retrieval, Analysis, Reasoning and Modelling for International Journal of Remote Sensing, which is released in October 2010. He is currently serving as an Editor of Discrete Dynamics in Nature and Society: a Multidisciplinary Research and Review Journal and served as an Associate Editor of IEEE-GRSL (2004-06). He has reviewed books and scientific articles for University Press (India), IEEE GRSL, Chaos Solitons & Fractals, Computers & Geosciences, International Association for Pattern Recognition, International Journal of Pattern Recognition and Artificial Intelligence, International Journal of Remote Sensing, Journal Mathematical Geology, Discrete Dynamics in Nature and Society, IEEE Transactions on Pattern Analysis and Machine Intelligence, Tribology,IEEE Transactions on Geoscience and Remote Sensing, IEEE Geoscience and Remote Sensing Letters.
