I am a postdoctoral research fellow in the Machine Learning and
holding the AstraZeneca Data Science Fellowship
. My project focuses on subgroup analysis in clinical trials by developing an artificial intelligence and machine learning framework, to enable robust rankings of putative predictive biomarkers of treatment efficacy.
Prior to that, I did my PhD in the School of Computer Science
under the supervision of Dr Gavin Brown
During my PhD and my postdoctoral career, I have worked in various areas of machine learning, while my main research interests are in the area of information theoretic feature selection in different learning environments and particularly focusing on medical and health informatics applications.
Areas of interest:
, Feature Selection
, Multi-label learning
, Positive-unlabelled learning
, Semi-supervised learning
