Biography
I am passionate in exploring new knowledge through teaching and working with my students. I have been teaching computer vision, machine learning and AI for many years, enjoying and experiencing the rapid evolution in these fields. As a researcher, I am interested in applying machine learning to image and natural language understanding, with a particular focus on the medical domain. I have been working with a number of NHS hospitals, as well as hospitals in Europe and Asia, on a wide range of projects including: the development of automated tracking of fine movements of surgical instruments in eye and other microsurgeries; digital retinal image analysis to understand various eye and systemic conditions; time-lapse bacterial cell image analysis for understanding mycobacterial persistence. Beyond my passion in healing and care through medicine, I am also fascinated by the wonders of nature and keen to be part of it. This may be slightly reflected through the work that I participated in with the Royal Botanic Gardens, Kew, on Herbarium Image Data Analysis as well as the National Plant Phenomics Centre on heritage plants.
