Proposes a new way to characterise association-rule interestingness measures by how they respond to a unit change in the underlying contingency-table counts — a "rate of change" analysis that captures behaviours existing property-based classifications miss, helping practitioners pick the right measure.

Combines satellite and ground-level air-quality data to map NO₂ and PM₁₀ pollution across India's districts and cities (2005–19). Urbanization has an inverse relationship with NO₂ growth, yet the most urbanized districts carry the highest burden and those at intermediate urbanization (30–40%) see the largest increases — with the Indo-Gangetic Plain of particular concern.

A systematic, internationally-comparable analysis of how India's economic and human development and its personal income distribution evolve as a function of urbanization — finding that India outperforms most nations on several development indicators as its cities grow, even as distributional challenges persist.

Studies the distribution of income across Indian states (2014–19), finding wide heterogeneity in inequality. In high-inequality states the income shares and real growth of the bottom decile have declined, and a stochastic income-growth model reveals a net redistribution of resources from poor to rich.

Examines the evolution of income in India (2014–19): while aggregate inequality is broadly stable, the bottom of the distribution suffers large losses — the bottom ventile's income share falls ~38% with negative real growth — and the rural and urban bottoms diverge sharply.

How India's commercial health insurance segment could be redesigned to deliver real financial protection on the path to universal health coverage — examining the behaviourally-realistic consumer on the demand side and the barriers a new insurer faces on the supply side, including the role of vertical integration between insurers and providers.

Proposes a risk-based supervision model for a data-protection authority — a methodology to classify entities by the risk they pose when the personal data they hold is compromised, paired with a responsive-regulation enforcement toolkit for use before and after a breach.

Explores the relationship between SU(2) representations used to express rotation and angular-momentum operators in quantum mechanics, and builds the background needed to understand the construction of the Atiyah conjecture.
