About

A seasoned ML quantitative researcher with expertise in building systematic alpha strategies, ML modeling using alternative data, asset allocation, and thematic indexes.

With over 8 years of experience spanning buy-side asset managers, index providers, and fin-tech startups across India and Norway, I bring a global perspective to quantitative finance. Currently at DNB as a Senior Risk Quant, I lead validation projects of counterparty credit risk, valuation, liquidity, and credit risk models.

As a team lead and manager of research in previous roles, I have been instrumental in owning research projects end-to-end — conducting research, collaborating with internal and external stakeholders, and mentoring junior team members. I have contributed to global publications including SSGA's Global Market Outlook, whitepapers, and articles for a global buy-side audience.

I currently serve as Styreleder (Chairman) of Norsk Forening for Kvantitativ Finans — the Norwegian Association for Quantitative Finance.
