N. Padmanabhan

Professor
PhD (Applied Mathematics), Indian Institute of Science, Bangalore
Areas of interest
Image Processing, Linear Algebra, Mathematical Modelling

N. Padmanabhan is a Professor in the School of Engineering and Applied Science since January 2015.  He obtained his PhD from the Indian Institute of Science, Bangalore, on Theoretical Modelling of the Fluid Mechancs of the Cardiovascular system.  After a stint of Post Doctoral stuies at IIT Delhi and Cambridge Universty, he joined Space Applications Centre (ISRO), Ahmedabad as a Scientist.  While in ISRO, he designed, developed and implemented algorithms for  generating data products from the Indian Remote Sensing and Meteorological satellites.    He worked at the Indian Institute of Space Science and Technology, Thiruvananthapuram as an Adjunct Professor for two years and one year at the Indian Institute of Information Technology, Vadodara, before joining Ahmedabad University in 2014.

His primary interests are Linear Algebra, Image Processing and Mathematical Modelling of real life problems.

 

 

Am interested in Digital Image Processing, Mathematical Modelling for real life problems and Linear Algebra
