He has more than 20 publications to his credit that include research papers, monograph and book chapters. He is actively involved in teaching undergraduate and postgraduate students as well as PhD students. He is a member of many professional societies such as American Mathematical Society (AMS), International Society for Augmentative and Alternative Communication (ISAAC), International Association of Engineers (IAENG) and Indian Mathematical Society (IMS).H.M. SRIVASTAVA is professor emeritus at the Department of Mathematics and Statistics, University of Victoria, Canada. He joined the University of Victoria in 1969, firstas associate professor (1969–1974), and then as full professor (1974–2006). Professor Srivastava has held numerous visiting positions including (for example) those at West Virginia University in the U. S. A (1967–1969), Universite Laval in Canada (1975), and the University of Glasgow in the U. K. (1975–1976), and indeed also at many other universities and research institutes in different parts of the world. Professor Srivastava has published 21 books (monographs and edited volumes), 30 book chapters, 45 papers in international conference proceedings, and over 1,000 scientific research journal articles on various topics of mathematical analysis and applicable mathematics. In addition, he has written forewords to several books by other authors and to several special issues of scientific journals. He has also edited (and contributed to) many volumes, which are dedicated to the memories of famous mathematical scientists. Citations of his research contributions can be found in many books and monographs, PhD and D.Sc. theses, and scientific journal articles, much too numerous to be recorded here. Currently, he is actively associated editorially (that is, as editor, honorary editor, senior editor, associate editor or editorial board member) with over 200 international scientific research journals. His biographical sketches (many of which are illustrated with his photograph) have appeared in various issues of more than 50 international biographies, directories and Who’s Who’s.
