Trinity University, Bachelor of Science
Oregon State University, Ph.D.


In 2011, Professor O. Maduka Ogba earned his B.S. in computer science and minor in chemistry at Trinity University in San Antonio, Texas. While at Trinity, Prof. Ogba conducted research with Prof. Steven Bachrach in his computational organic chemistry group.  

In 2016, he was awarded his Ph.D. in chemistry at Oregon State University for work with Prof. Paul Ha-Yeon Cheong developing computational routines for investigating complex organocatalysis and reaction processes. From 2016 to 2018, Maduka conducted his Robbins Postdoctoral Fellowship at Pomona College, California working with Prof. Daniel J. O’Leary using computational NMR chemical shifts and isotope effects predictions to probe molecular structure, non-covalent interactions, and chemical transformations.

In 2018, Prof. Ogba joined Chapman University as an assistant professor of chemistry in Schmid College of Science and Technology. In this role, Prof. Ogba enjoys working with students in his computational chemistry research lab (The OMO Lab) to (i) study the underlying chemical interactions governing molecular structure, reaction mechanisms, and selectivity in chemical transformations, and to (ii) develop software and informatics tools for chemists to use to rapidly mine, analyze, and visualize chemical data. Prof. Ogba also enjoys teaching students fundamental theories in organic and computational chemistry.


On February 18, 2019, Dr. Ogba was a guest speaker for Schmid College's Science on Tap Series.
