Gabriela Ochoa

Gabriela Ochoa
is a Senior Lecturer in Computing Science at the University of Stirling, Scotland.  She received BSc and MSc degrees in Computer Science from University Simon Bolivar, Venezuela and a PhD from University of Sussex, UK.  She worked in industry for 5 years before joining academia, and has held faculty and research positions at the University Simon Bolivar, Venezuela and the University of Nottingham, UK.  Her research interests lie in the foundations and application of evolutionary algorithms and heuristic search methods, with emphasis on autonomous (self-*) search, hyper-heuristics, fitness landscape analysis, and applications to combinatorial optimisation, healthcare, and software engineering. She has published over 90 scholarly papers and serves various program committees. She is associate editor of Evolutionary Computation (MIT Press), was involved in founding the Self-* Search track at GECCO, proposed the first Cross-domain Heuristic Search Challenge (CHeSC 2011). She has served as organiser and/or program chair for EvoCOP 2014, EvoCOP 2015FOGA 2015, PPSN 2016, and  will be the Editor in Chief for GECCO 2017.  She is a member of the CHORDS research Group, and a co-investigator of the DAASE project.
