TEACHING AND RESEARCH
(a) TEACHING (BITS, Pilani)
· Core courses: For 7 semesters, I was the Instructor - in - Charge of B.E.(II year) multisection courses – Electronics (ES C252) in one semester and Circuit Theory (ES C231) in the other – which are taken by the students of all engineering branches in this Institute (numbering about 550). Apart from teaching a section, I was responsible for setting up of question-papers, conduct of examinations, evaluation and grading for these courses for all the students.
· BE(EEE) discipline courses Other BE courses taught are: Electromagnetic Fields and Waves (EEE C433), Electromagnetic Fields and Microwave Engineering (EEE C452), Circuits and Signals (EEE C372), and Data Communications and Networking (BITS C372), Digital Electronics Lab (EEE C364), and Analog Electronics Lab (EEE C391).
· ME Courses developed and taught : Advanced Electronic Circuits (EEE G621),
RF and Microwave Engineering (EEE G581), Mobile and Personal Communications (EEE G592) and Data Compression (BITS G 554).
(b) TEACHING (GIST, South Korea)
During 2 years’ leave (Aug 2002 to July 2004), I worked in the Deptt. Of Information and Communications, Gwangju Institute of Science and Technology (GIST), South Korea as a “Foreign IT Professor” under a scheme of the Government of South Korea. GIST is a graduate school which offers only MS and Ph.D. programs and is fully financed by the Government. In the above institute, I taught the following five graduate level courses: (i) Information and Coding Theory (DIC 1609), (ii) Wireless Communications (DIC 1624), (iii) Integrated Circuit Design (DIC 1627), (iv) Computer Networks and Communications (DIC 1641), and (v) Microwave Engineering (DIC 1655).

© RESEARCH
My research activity has been mainly in the following three areas: ISM Applications of Microwave Energy, Image Compression and Applications of Information Theory to Source Coding. The details are given below.
· ISM Applications of Microwave Energy
Besides communications, microwave energy has many other industrial, scientific and medical (ISM) applications. During my Ph.D program, I worked in this area. To generate sufficient awareness for these applications in India, I have written four review articles in this area. Three of these have been published in the Technical Review of the Institution of Electronics and Telecommunications Engineers (IETE), India. One of these was selected as the best paper in the category of industrial applications and was given CDIL Award by the IETE in 1994.
· Image compression
Data compression is considered as the key enabling technology for ushering in and sustaining the information revolution. Improved versions of some image coding techniques for monochrome images were developed. One of our paper was given K S Krishnan Memorial Award of the IETE in 1997 for being the best systems oriented paper published in the IETE Journal of Research in 1997. At present, we are looking into wavelet based image compression techniques.
· Information Theory
The source coding work brought me closer to Information theory. In GIST, South Korea, I offered a graduate course in this area (Information and Coding Theory; DIC 1609) with the text book, ‘Elements of Information Theory, T M Cover and J A Thomas, John Wiley, 1991’. After returning to India I have written the following four tutorial papers in the IETE Journal of Education: (i) Information theory and its two basic applications, (ii) Applications of information theory to spectral estimation, and (iii) Joint source and channel coding, and (iv) Fractals and their applications in Image Compression. I cover information theoretic aspects of lossless and lossy compression in the graduate course on “Data Compression” taught in my Institute.
