Ke most recently brings quantitative analytics experience from JPMorganChase, where Ke designed a multi-agent AI system for LLM model validation to reduce manual review work and developed a volatility-based 99% VaR lending-value framework for equity collateral involving recently IPO’d equities. Ke’s core strength is building and evaluating quantitative models end to end, then translating their outputs into practical financial decisions and clear risk-reward trade-offs for leadership. Ke has particular depth in volatility modeling—including realized volatility, implied volatility, and hybrid approaches—along with stress-testing frameworks for risk models and classical quantitative risk work in VaR and equity-collateral risk. Ke also applies software-engineering practices such as unit testing and quality-control pipelines. Earlier work includes return prediction and trading-strategy design at Stratify Solutions, quantitative research at Caida Securities, cross-border banking at East West Bank, corporate banking at China Construction Bank New York Branch, and contributions to scikit-learn. Ke holds an MS in Financial Mathematics from the University of Chicago and a bachelor’s degree in Mathematics and Computer Science from New York University. ## Highlights - Designed a multi-agent AI system for LLM model validation at JPMorganChase, reducing manual review work. - Built a volatility-based 99% VaR lending-value framework for equity collateral at JPMorganChase, including recently IPO’d equities. - Worked on return prediction and trading-strategy design at Stratify Solutions. - Brings expertise in realized volatility, implied volatility, and hybrid volatility-modeling approaches. - Has experience building stress-testing frameworks for risk models. - Applies quantitative risk expertise across volatility modeling, VaR frameworks, and equity-collateral risk. - Builds and evaluates quantitative models end to end and translates them into financial decisions. - Implements unit testing and quality-control pipelines as part of software-engineering practice. - Communicates complex technical and risk trade-offs effectively to leadership. - Served as a Quantitative Analytics Summer Associate at JPMorganChase. - Served as a Quantitative Research Intern at Caida Securities Co., Ltd. - Served as a Cross Border Banking Summer Analyst at East West Bank. - Served as a Corporate Banking Analyst at China Construction Bank New York Branch. - Contributed to scikit-learn as an Open Source Developer. - Served as a Quantitative Researcher with the University of Chicago Project Lab at Exponential Technology Inc. - Earned an MS in Financial Mathematics from the University of Chicago. - Earned a bachelor’s degree in Mathematics and Computer Science from New York University. ## Experience - **Quantitative Analytics Summer Associate at JPMorganChase** (2026-06-01–2026-08-01) - **Quantitative Researcher - University of Chicago Project Lab at Exponential Technology Inc.** (2025-10-01–2025-12-01) - **Quantitative Research Intern at Caida Securities Co., Ltd.** (2024-09-01–2024-12-01) - **Cross Border Banking Summer Analyst at East West Bank** (2024-06-01–2024-08-01) - **Open Source Developer at scikit-learn** (2023-04-01–2023-04-01) — Contributor to scikit-learn - **Corporate Banking Analyst at China Construction Bank New York Branch** (2022-07-01–2022-08-01) ## Education - Master of Science - MS, Financial Mathematics — University of Chicago (2025-01-01–2026-01-01) - Bachelor's degree, Mathematics and Computer Science — New York University (2021-01-01–2025-01-01) ## FAQ ### What does Ke do?
