Vijay Kumar Vaishnavi is a noted researcher and scholar in the computer information systems field with contributions mainly in the areas of design science, software engineering, and data structures & algorithms, authoring over 150 publications including seven books in these and related areas,[1][2][3][4][5] and co-owning a patent.

[12][13] Over these years the GSU CIS department has gained considerable reputation; its research and academic programs are very highly ranked.

[14] Vaishnavi was elected as an IEEE Fellow, 2002, with the citation:[15] "For contributions to the theory and practice of software development."

Between 1992 and 1998, he worked as a founding research director (along with the executive director, Timothy Korson, at COMSOFT, the Consortium for the Management of Emerging Software Technologies; COMSOFT (sponsored by companies such as IBM, AT&T, Bell South, and Nortel) facilitated object technology transfer to companies.

[37] In this regard, Mehlhorn and Näher write (on p. 215 of their 1990 article) that several researchers including Vaishnavi and Wood "observed that the naïve strategy of locating the key separately in each list by binary search is far from optimal and that more efficient techniques frequently exist."

They further write that Chazelle and Guibas[38] "distilled from these special case solutions a general data structuring technique and called it fractional cascading."
