About

With over 13 years of experience at the intersection of research, analytics, marketing strategy, and business intelligence, I specialize in converting complex data into actionable insights that fuel growth and innovation. My expertise spans advanced statistical modeling, causal inference, media optimization, and cross-functional leadership across global and regional teams. Currently, I lead marketing analytics for Dell’s India business, acting as the single point of contact for evaluating media performance, forecasting outcomes, and optimizing investments through Media Mix Modelling (MMM). I also shape global analytics strategy by integrating deep research, predictive modeling (R), and business forecasting into scalable, high-impact solutions. I’ve spearheaded the transformation of Dell’s Global Test & Learn program—executing 110+ experiments in a year with a $2M+ budget per quarter and delivering insights that influence over $50M in quarterly revenue. My work bridges experimentation, MMM, and media planning through a unified triangulation framework adopted by SVP-level leadership. Driven by innovation, I’ve embedded scientific rigor into experimentation, automated reporting systems, and led award-winning initiatives in data validation, taxonomy alignment, and strategic planning. Whether building statistical models, designing dashboards, or guiding global investment strategy—I thrive on solving complex problems with clarity, precision, and purpose.
