I'm a quantitative scientist pursuing a PhD in System Modeling & Analysis at Virginia Commonwealth University (VCU). I turn mathematics into production-ready models for risk, pricing, forecasting, and decision support in finance and insurance.
I hold a BSc in Actuarial Science (KNUST, Ghana), an MS in Applied Mathematics (Ohio University), and an Advanced Diploma in Insurance (Chartered Insurance Institute, UK). My toolkit includes Python, R, and SQL, with methods spanning GLMs/gradient boosting, survival analysis, ARIMA/GARCH, Bayesian inference, Monte Carlo simulation, and optimization. I emphasize clear assumptions, reproducible pipelines, and documentation teams can ship.
Previously, I served as a Reinsurance Analyst at Phoenix Insurance, supporting treaty and facultative placements, building loss/exposure summaries and pricing indications, and coordinating with brokers and cedents on wording and claims development. As a Branch Manager at Quality Life Assurance, I led underwriting and customer operations, managed P&L targets and sales pipelines, and partnered with actuarial and claims teams on product and pricing decisions.
I enjoy taking models from notebook to production—stress-testing with backtests and scenario analysis, monitoring stability, and communicating results in plain language to underwriters, product teams, and leadership.
