Achievements

•          Six research scholars have completed their research work (for a Ph.D. degree) under my guidance (Four students have got their degrees and two have submitted their theses). These have been in the areas of Stream Cipher Systems, Space Time Block Codes for use on Wireless channels, Algebraic codes applied to Storage Devices for achieving information integrity, Application of Error Control codes to Power line channels, Evaluation of performance of Chaotic-MIMO systems to improve performance over Wireless channels and application of Fountain Codes to enhance information integrity over Free Space Optic Communication channels. Two research students are currently working on their research problems under my guidance. I have also guided one M.Tech. (by research) dissertation in the academic year 2011-13.

  

•          I have successfully completed a major Research project entitled ` Secure Turbulence Resistant Free Space Optical (FSO) Links for Broadband Wireless Access Networks’ with an outlay of Rs. 130.56 Lakhs (Rs. 13.056 million). We carried out collaborative projects with the Light Wave and Optical Systems (LEOS) laboratory of the Indian Space Research Organization (ISRO) and the Transmission R&D group of Indian telephone Industries (ITI) Limited with the support provided by the project. Duration: July 2010 to December 2013.

(jointly with Prof. M. Kulkarni)

 

•          A second research project entitled ` Uncoordinated, Secure and Energy Aware Access in Distributed Wireless Networks (jointly with IIT Bombay, TIFR Mumbai, and IIT Durgapur) sponsored by Information Technology Research Academy, Media Lab Asia with a Project Outlay of Rs. 20.25 Lakhs (for NITK) and a duration of three years (December 2013-December 2016) is under progress under my supervision at NITK.

 

•          Design and commissioning of Simulator for training railway personnel on the Indian Railway Signaling System Client: Konkan Railway Corporation.

(jointly with Prof. Ramesh Kini M).

 

•          I have been assisting Public Sector banks (jointly with Prof. Laxminidhi T) since 2009 (Corporation Bank, Syndicate bank, Vijaya bank) in their procurement of Currency note machines. This work involves assisting the respective banks in the framing of the Technical specifications of the machines for the tender, evaluating the machines for their compliance with specifications laid down by the Reserve Bank of India and conducting field tests to assess features such as the consistency of the machines during note sorting, the ability of the machine to detect suspect (fake) notes and the ability of the machine to perform the expected duties under working conditions prevailing in the Currency Chests/ branches in India.

 

•         I was appointed as the Nodal Officer (academic) of the TEQIP-II program at NITK. I am currently also discharging the responsibilities of Co-coordinator of this project. I (along with Dr. Laxminidhi T) have designed a number of schemes (the scheme of Half Time Teaching Assistants, Postgraduate Research Associates, peer mentoring of First year students by Third year students etc were designed by us) to improve the teaching-learning environment at NITK with the support provided by this project. I have personally conducted several workshops (and facilitated the conduction of many more) to foster research and R&D activities at NITK.

 

•          I have taught seven theory and three laboratory courses in the past four years at both UG and PG level at NITK. These courses are Electromagnetic Waves, Antennas and Propagation, Detection and Estimation Theory, Error Control Coding, MIMO Wireless Communication, Mathematical Foundations for Communication Engineering and Microwave Engineering. I have also served as the instructor for Basic Communication Lab, Advanced Communication lab and Product Design laboratories. I have also designed and fabricated several specialized instruments for the use of research scholars of Physics, Chemistry and Mechanical Engineering Departments.
