# Rigoberto Hernandez

Rigoberto Hernandez (born 1967) is an American chemist and academic. He is The Gompf Family Professor at the Johns Hopkins University and was formerly a board member of the American Chemical Society (ACS). Before his appointment at Johns Hopkins, Hernandez spent 20 years as a faculty member at the Georgia Institute of Technology, where he became a full professor. In addition to his work as a professor, Hernandez is the director of the Open Chemistry Collaborative in Diversity Equity, a program dedicated to creating more diversity in academia. Hernandez will serve as the President of the American Chemical Society in 2026.

## Biography

Born in Havana, Hernandez moved to Spain with his family when he was a child. The family later moved to Florida, where Hernandez attended school. When he was in high school, a research program at the University of Miami sparked an interest in science. He attended Princeton University, where he earned an undergraduate degree in chemical engineering and mathematics in 1989. Four years later, he received a Ph.D. in chemistry from the University of California, Berkeley.
After serving on the chemistry faculty at Georgia Tech for 20 years, Hernandez moved to Johns Hopkins University in 2016. He has special interests in the dynamics of chemical reactions, transition state theory and non-equilibrium stochastic dynamics. Hernandez describes his area of study as "the interplay between molecular motions — such as reactions or rearrangements — and changes in their environments".

## President and Service to the ACS

Hernandez represented District IV as a Director on the Board of Directors of the American Chemical Society (ACS) for two terms from 2014 to 2019. He was elected to serve in the ACS Presidential Succession from 2025 to 2027. He will serve as the President in 2026 when the ACS will celebrate its sesquicentennial.

## OXIDE

Hernandez directs a program known as the Open Chemistry Collaborative in Diversity Equity (OXIDE). The program supports research and awareness into issues of diversity within chemistry departments. The program, which Hernandez started when he was at Georgia Tech, was initially funded by the National Science Foundation, National Institutes of Health and U.S. Department of Energy, and later the Sloan Foundation. OXIDE is dedicated to creating changes in science departments by making changes from the top down. This includes creating policies that do not exclude diversity and foster more inclusive environments. In the fall of 2016, the OXIDE program moved to Johns Hopkins.
