Data Scientist, Machine Learning Expert and Consulting Actuary with 8+ years experience in healthcare

Summary

I’m the co-founder of Mast Analytics, a healthcare focused data science and analytics startup. The mission of our company is to use data science, machine learning and analytics to improve public health. We define public health broadly to include social determinants of health such as education and environmental health. I have a degree in mathematical statistics and am currently completing my M.Sc. in Computer Science with a dissertation focused on multi-label clinical text classification for long documents in a high-dimensional, imbalanced label space. I’m also a qualified healthcare actuary which has equipped me with the skills to do complex and long-term financial modelling. I have completed graduate-level courses from edX Columbia University, also known as ColumbiaX, in artificial intelligence, machine learning and robotics. I have over 8 years’ experience working on machine learning and advanced analytics projects. My most recent projects include training an unsupervised machine learning algorithm to do population segmentation based on clinical datapoints collected through an ecosystem of connected wearable devices and point-of-care pathology machines. We are also building up a suite of medicine machine learning models, including models to detect signs of disease from x-ray images and classifying electrocardiogram data. My friend, colleague and co-founder of Mast Analytics has a different academic and professional background to me and brings clinical and public health expertise as well as academic rigor to all our work. She is a qualified pharmacist and holds a Master of Public Health degree from Johns Hopkins. During her career, she’s fulfilled numerous roles in both clinical and data analytics teams. Prior to forming Mast Analytics, we worked together for several years at a large third-party administrator and managed care organization in South Africa. We collaborated on a range of projects, including developing predictive models, profiling providers, designing alternative reimbursement systems, measuring quality of care and doing financial and clinical outcomes analyses. Along with a former colleague of ours, we were awarded the 2014 Starfield Award by the Johns Hopkins Bloomberg School of Public Health’s ACG System® team for our work in identifying emerging risk individuals through machine learning using administrative health data, designing an intervention plan for the identified individuals and measuring clinical and financial outcomes of the program.
