Dr. James Chambua is a Lecturer and Postgraduate Studies Coordinator at the Computer Science and Engineering Department at the University of Dar-es-Salaam. He is also a mentor and supervisor for the Artificial Intelligence for Development in Africa (AI4D Africa) Scholarship Programme, an initiative funded by the International Development Research Centre (IDRC) and managed by the African Centre for Technology Studies (ACTS). Dr. Chambua holds a Bachelor of Science with Computer Science, and a Master of Science in Computer Science focusing on localization of Open-Source Software to Swahili, from the University of Dar-es-Salaam. He also holds a doctorate degree in Computer Science and Technology specializing in Artificial Intelligence and Machine Learning Algorithms from the Beijing Institute of Technology - China. 

His research focuses on understanding, designing and extending AI/ML algorithms for recommendation, retrieval and classification systems, evaluating the impact of users’ review texts and auxiliary information. Dr. Chambua research has explored and leveraged artificial neural networks, specifically Recurrent Neural Network (RNN), Long-Short Term Memory (LSTM) and Convolution Neural Networks (CNN), to capture semantic similarities, linguistic patterns and user sentiments. His research works have been published in international journals including Artificial Intelligence Review, Expert Systems with Applications, Neurocomputing, Weather, Knowledge-Based Systems, IEEE Transactions on Knowledge and Data Engineering and UDSM library.
