B S Daya Sagar FRGS(born in 1967 in India) is an Indian Mathematical Geoscientist specializing in Mathematical Morphology. He is an Associate Professor in Computer Science in Indian Statistical Institute, Bangalore[6]. He is known as one of today's pioneers whose focus is on mathematical morphology, fractal geometry. chaos theory, and their applications in geophysics, geographical information science, and computational geography. He was awarded the Krishnan Medal in 2002 for his significant studies in the field of Applications of Remote Sensing, Mathematical Morphology and Fractals to Study Certain Surface Water Bodies, and the Georges Matheron Lectureship in 2011 for his outstanding research ability in the field of Spatial Statistics or Mathematical Morphology.

Education

Daya Sagar had his school and collegiate education at St Anthony School-Visakhapatnam, Government High School-Samalkota, Government Arts College-Srikakulam, India. He graduated with BSc in 1987 from Shree Durga Prasad Saraf College of Arts and Applied Sciences-Sriramnagar, an affiliated college of Andhra University. Subsequently, he received the M.Sc and PhD degrees from the Andhra University College of Engineering-Visakhapatnam, India, in 1991 and 1994 respectively. His PhD thesis is on 'Applications of Remote Sensing, Mathematical Morphology, and Fractals to Study Certain Surface Water Bodies'.

Career

Sagar currently is an Associate Professor at Systems Science and Informatics Unit (SSIU) of Indian Statistical Institute—Bangalore Centre, India. Earlier (1991-1998), he worked in Andhra University College of Engineering as a project assistant (1991–92) in a project 'PC-Based Image Processing System' funded by Ministry of Human Resource Development, a Senior Research Fellow (1992–94) of Council of Scientific and Industrial Research (CSIR), a Research Associate (1994–95 and 1998-98) of CSIR, a Research Scientist/Principal Investigator (1997-7) in a Scheme for Extramural Research for Young Scientists funded by Ministry of Science and Technology. From 1998-2001, he worked as a Grade-A Research Scientist at the Centre for Remote Imaging Sensing and Processing (CRISP), the National University of Singapore. He was appointed Associate Professor of Faculty of Engineering and Technology, Multimedia University (MMU), Malaysia in 2001. He was also a Deputy Chairman of Centre for Applied Electromagnetics (2003–07) at the MMU, Malaysia. Since 2007, he has been an Associate Professor at Indian Statistical Institute-Bangalore centre, and since 2009, he has been overseeing as founding head of SSIU, a unit that was established in 2009 as one of the five constituent units of Computer and Communication Sciences Division.

Research

Daya Sagar’s two-decade long unique research contributions span both basic and applied fields involves fusion of computer simulations and modeling techniques with a goal of developing cogent models in discrete space to gain a significantly good understanding of the dynamical behaviors of complex terrestrial systems (e,g: water bodies, river networks, mountain objects, folds, dunes, landscapes, rock porous medium, epidemic etc). Efficient way of understanding the dynamical behavior of many complex systems of nature, society and science is possible through data acquired at multiple spatial and temporal scales. The utility and application of such data for developing cogent domain-specific models that provide the spatiotemporal behaviors of systems of geoscientific relevance could be substantially enhanced through related technologies and spatial algorithms developed by him. His works can be singled out as significant contributions whereby the concepts stemmed out of recent theories—such as mathematical morphology, fractals, chaos, and morphometrics—have been employed to develop spatial algorithms eventually used in (i) pattern retrieval, (ii) pattern analysis, (iii) simulation and modeling, and (iv) reasoning and visualization of the spatial and/or temporal phenomena of terrestrial and GISci relevance. His studies also show that there exist several open challenges that need to be addressed by mathematical geosciences community. One of such challenges is to understand the complexity in spatiotemporal behaviors of several terrestrial phenomena and processes via construction of process-specific attractors that may range from simple to strange.

Professional

Sagar has been honored with awards such as Georges Matheron Lectureship Award of International Association for Mathematical Geosciences 'for outstanding research ability in the field of spatial statistics or mathematical morphology'. In 2002 he received Krishnan Medal of the Indian Geophysical Union. As recipient of this medal, Sagar was made IGU Fellow in 2011. In 1995, he received Dr. Balakrishna Memorial Award from the Regional Centre of Andhra Pradesh Akademi of Sciences. He is an elected Fellow of Royal Geographical Society (1999), Fellow of Indian Geophysical Union (2011), Senior Member of IEEE (2003) and was a member of New York Academy of Science during 1995-96. He is on the Editorial Boards of Discrete Dynamics of Nature and Society, and Computers & Geosciences. He has published 60+ papers in peer reviewed international journals, 2 books, and 7 edited Special-Theme issues for well known journals.[7] He has been on Editorial Boards of Computers and Geosciences and Discrete Dynamics in Nature & Society.
