Research projects

Dr Ojha worked as a Marie-Curie Fellow in a European Union-funded project on interdisciplinary research concerning computational intelligence modelling of pharmaceutical processes.

Background

Dr Ojha worked as a postdoctoral researcher at ETH Zurich, Switzerland in a Swiss National Science Foundation project concerning machine learning and signal processing for pattern analysis of human's perception of the urban environment. He was awarded a PhD in Computer Science and Applied Mathematics by the Technical University of Ostrava, Czech Republic. His PhD work was on feature selection and function approximation using adaptive algorithms.

Before this, Dr Ojha worked as a research fellow in a Government of India funded-project on interdisciplinary research aims at machine learning and signal processing based pattern recognition of mixed gases. He earned a Master of Technology and Bachelor of Technology in Computer Science & Engineering.

Professional bodies/affiliations

Dr Ojha is an Institute of Electrical and Electronics Engineers (IEEE) senior member and member of the Association of Computing Professionals (ACM).
