Rohitash Chandra, PhD

Rohitash Chandra is a Research Fellow in Computer Science. He holds a PhD in Computer Science from Victoria University of Wellington, MSc in Computer Science from the University of Fiji and BSc from the University of the South Pacific. His research interests in general encircle the methodologies and applications of Artificial Intelligence. More specifically, he is interested in Neural and Evolutionary Computation methods such as Feedforward and Recurrent Networks, Genetic Algorithms, Cooperative Coevolution and Neuro-evolution with applications in Pattern Classification, Time Series Prediction, Control , Robot Kinematics and Environmental Informatics. He is currently working on problems in Computational Biology focusing in Metabolic Flux Analysis.

Apart from his interest in science, he is actively involved in literature and has been the editor of the Blue Fog Journal. He is also a poet and his third poetry collection is named ‘‘Being at Home’’ which is due to be launched in 2012. He is also the founder and coordinator of the Software Foundation of Fiji.
