Dr. Kaliappan Gopalan

Dr. K. ‘Gopal’ Gopalan has been with the Department of Electrical and Computer Engineering at Purdue University Calumet, Hammond, Indiana since 1985, currently holding the position of Professor.  He has been awarded the Outstanding Sponsored Research Scholar Award in 2009 and the Outstanding Faculty Scholar Award in 2002 and 2010, all at Purdue University Calumet.  He received his Bachelor’s degree in Electrical Engineering from P.S.G. College of Technology (University of Madras), Coimbatore, India, Master’s degree in Electrical Engineering from the Indian Institute of Technology, Kanpur (IITK), India, and Ph.D. degree in Engineering from the University of Akron, Akron, Ohio.  From 1974 to 1979, he was employed as a research engineer at IITK developing research instrumentation systems.

From 1987 to 1995 he conducted research in the areas of signal and image processing for nondestructive evaluation of advanced materials at Argonne National Laboratory, Argonne, Illinois, first as a summer faculty research participant and later as a consultant.  In addition, he has been a summer faculty research associate at Wright-Patterson Air Force Base, Ohio, and the Air Force Research Laboratory (AFRL), Rome, New York.  His research in speech analysis, speaker recognition, audio steganography, and keyword recognition has been funded by AFRL, Rome, NY.  He has received three U.S. patents, all on audio steganography and data embedding.

Gopalan gave keynote addresses on Keyword Spotting in Speech Communication – An Overview at (a) the 8th International Conference on Computing, Communications and Control Technologies, Orlando, FL, in April 2010, and (b) the International Workshop on Multimedia Streaming, Kochi, India, in July 2011.  He presented a tutorial on audio watermarking and steganography at the 55th International Midwest Symposium on Circuits and systems (IEEE MWSCAS 2012), Boise, Idaho, in August 2012, and a one-hour talk on Information Hiding in Audio Signals at the IEEE Chicago Section meeting in November 2012. Also, in July 2013, he presented a tutorial on Information Hiding in Audio Signals for Watermarking, Steganography and Covert Communication Applications at the IASTED Signal and Image Processing Conference held in Banff, Canada.  In addition, he has given several invited presentations at universities and colleges in Australia, India, Malaysia and Singapore.

Gopalan is a Life Senior Member of the IEEE and is the author of two textbooks, Introduction to Digital Microelectronic Circuits (Irwin/McGraw-Hill, 1996), and Introduction to Signal and System Analysis (Cengage, 2009).
