Research Scientist

Palo Alto Research Center

Leading Automated Planning efforts contributing to a variety of research projects (commercial and government-funded). Developing AI Planning algorithms and techniques, modelling complex systems.

October 2019 - present

Research Associate

Engineering Design Centre, University of Cambridge

Working on the TOICA & APROCONE projects aiming to develop an innovative aircraft design environment (with Airbus, GKN, Rolls-Royce, and Cranfield University). Researching and developing innovative Visual Analytics approaches for interactive visualisation and control of complex multidimensional engineering design data. Developing Machine Learning and optimisation methods to automate parts of the aircraft design process, improve accuracy and efficiency of the designs, and support the analysis of the data, as well as handle uncertainties in the models. The developments are being implemented into the Cambridge Advanced Modeller (CAM) using Java and Python programming languages.
