Lester I. McCann

Lester I. McCann is a Professor of Practice in the Department of Computer Science at the University of Arizona, with his office located in GS 819. He earned his Ph.D. from North Dakota State University in 1994 and maintains active contributions to computer science research and education.

Educational Background:

• Ph.D., North Dakota State University, 1994

Professor McCann's research centers on Computer Science education and database management systems. He developed innovative educational tools including "Graph Magic" for visualizing graph algorithms and "Guided slides" for tablet-based flexible lectures. His database work addresses relational algebra comprehension and concurrency control in high-performance computing environments, bridging theoretical concepts with practical pedagogy.

His publication timeline from 1990-2008 reveals a strategic shift from foundational database research (multidatabase systems, concurrency control) toward educational technology development. This evolution highlights sustained commitment to enhancing computer science instruction through software tools, assignment design, and visualization techniques across algorithms, data structures, and database courses.
