Gabriela Ochoa is a Venezuelan British computer scientist and Professor at the University of Stirling. Her research considers evolutionary algorithms and heuristic search methods.

Early life and education

Ochoa was born in Venezuela. Her grandfather was a doctor, and she became interested in science at an early age. She earned her bachelor's degree at the Simón Bolívar University, where she remained for her master's degree and worked as a teacher's assistant. She moved to the United Kingdom for her graduate studies, where she joined the University of Sussex as a doctoral student. At Sussex Ochoa worked on genetic algorithms with Hilary Buxton and Inman Harvey. After graduating she returned to Venezuela, where she was made Associate Professor at the Simón Bolívar University.

Research and career

In 2006 Ochoa once again left Venezuela, and moved to Paris to join the French Institute for Research in Computer Science and Automation. She worked there for three months with Dr. Evelyne Lutton before joining the University of Nottingham. By 2012, Ochoa had relocated to the University of Stirling, where she was promoted to Full Professor.

Her research considers evolutionary algorithms and heuristic search methods. She has worked on the computational design of medical treatments in an effort to minimise antibiotic resistance in Scotland.

Supported by the Leverhulme Trust, Ochoa created the website Lon Maps, a space which looks to establish visualisation techniques for computational search spaces. In 2020 Ochoa was awarded the EvoStar Award for Outstanding Contribution to Evolutionary Computation in Europe.

Academic service

Ochoa has been associate editor and served on many editorial boards, including the IEEE Transactions on Evolutionary Computation, Evolutionary Computation journal and the journal of Genetic Programming and Evolvable Machines. She is on the Executive Board of Association for Computing Machinery (ACM) Special Interest Group on Genetic and Evolutionary Computation (SIGEVO).
