# Sartaj Sahni

Professor Sartaj Kumar Sahni (born July 22, 1949, in Pune, India) is a computer scientist based in the United States, and is one of the pioneers in the field of data structures. He is a distinguished professor in the Department of Computer and Information Science and Engineering at the University of Florida.

## Education

Sahni received his BTech degree in electrical engineering from the Indian Institute of Technology Kanpur. Following this, he undertook his graduate studies at Cornell University in the USA, earning a PhD degree in 1973, under the supervision of Ellis Horowitz.

## Research and publications

Sahni has published over 280 research papers and written 15 textbooks. His research publications are on the design and analysis of efficient algorithms, data structures, parallel computing, interconnection networks, design automation, and medical algorithms.
With his advisor Ellis Horowitz, Sahni wrote two widely used textbooks, Fundamentals of Computer Algorithms and Fundamentals of Data Structures. He has also written highly cited research papers on the NP-completeness of approximately solving certain optimization problems, on open shop scheduling, on parallel algorithms for matrix multiplication and their application in graph theory, and on improved exponential time exact algorithms for the subset sum problem, among his many other research results.
