Senior馃帗
Top SchoolBen Postance is Head of Data Science with over a decade of experience applying machine learning and advanced analytics to commercial insurance and financial risk. He has repeatedly translated research-grade natural hazard modelling into pragmatic insurance solutions, improving loss ratios by up to 2.5% through better risk selection and underwriting models. Ben builds and scales high-performing data teams, drives AI governance and ethical deployment, and designs ML systems that deliver measurable ROI across underwriting, portfolio optimisation and automation. He doubled the data points used for risk selection by integrating open source, third-party sources and LLMs to materially boost predictive accuracy. A former PhD researcher published on the economic impacts of climate-driven hazards, he brings deep geoscience expertise to catastrophe modelling and resilience-focused product innovation. Based in London, he combines academic rigour with commercial execution to de-risk portfolios and influence policy-relevant peril modelling.
