Meet the Team
After working together for over a decade, we founded QML Solutions in 2024 to bring our quantitative expertise directly to clients. Together, we combine decades of experience in quantitative credit and equity research: building models, explaining them to investors, and producing strategy research notes. QML Solutions is our way of sharing our quantitative, data-driven insights into credit and equity markets. We provide research, interactive analytics tools, and custom quantitative solutions that help clients monitor risk, analyze market trends, and make data-driven decisions. We believe quant research can be both rigorous and accessible, and our goal is to provide insights and tools that are actionable and immediately relevant.
