About
As the first Chief AI Officer of Rockefeller Capital Management, Founder of the Applied AI Lab, and Co-Founder of the Rockefeller Academy for AI Innovation, I lead the firm’s AI transformation at the intersection of AI strategy, execution, and responsible speed to scale with a clear mandate: turn AI from experimentation into durable impact in wealth management and financial services. Leading AI agentic development from Zero to Enterprise platform scalability across the organization. I have initiated multiple strategic frontier relationships & collaboration, AI investment opportunities, and launched organization-wide AI training & enablement. Before Rockefeller, I led Global AI and advanced analytics initiatives at Amazon Web Services (AWS), where I worked with global enterprises, Fortune 500 companies, and governments to design, build, and deploy AI systems at scale, operating at the frontier of cloud-native data platforms, machine learning, and production-grade AI. That experience shaped how I approach AI today: pragmatic, outcomes-driven, and engineered for real-world complexity. AI is no longer a technology function. It’s a leadership function.
