About

I am currently working at BlackRock, contributing to the Data and AI team with a focus on developing and deploying machine learning solutions that drive strategic decision-making. Previously, I was part of Fidelity Investments at their AI Centre of Excellence, where I specialized in Generative AI and Large Language Models (LLMs), working on projects that advanced the capabilities of natural language processing and understanding. I have also worked as Machine Learning Researcher at Stanford University, the University of Cambridge, HEC Paris, and Penn State University, where I engaged in cutting-edge machine learning research. These experiences have honed my skills in developing innovative AI solutions and deepened my understanding of complex data-driven systems. I am passionate about leveraging AI to solve real-world problems and am continually seeking opportunities to apply my expertise in machine learning and data science to create impactful solutions.
