My research sits at the intersection of artificial intelligence, climate science and sustainable urban development. Through the Centre for Urban Informatics, Technology and Policy (CITY), we co-develop decision support systems with city governments, multilateral organisations and academic institutions, with a focus on urban mobility, air quality and climate resilience.
Current research areas:
- AI and machine learning for spatiotemporal data: interpretable and scalable models for traffic forecasting, ride-hailing demand prediction and super-resolution of climate and weather data
- Climate modelling and high-performance computing: exascale climate emulators using spherical harmonic transforms and mixed-precision GPU computing (2024 ACM Gordon Bell Prize), and spatial statistics on the sphere
- Air quality and urban environment: GIS-based emission hotspot mapping, Low Emission Zone design for Lahore, smog and aerosol dynamics, land surface temperature and urban green space analysis
- Remote sensing and computer vision: tree cover estimation, flood mapping from multispectral satellite imagery, building footprint extraction and population disaggregation
- Urban mobility and intelligent transportation: travel demand management, active traffic management and road safety
- Energy, environment and health: renewable energy systems, IoT-enabled monitoring, and clean household energy for cooking and heating and its impact on air pollution and health
- Industrial AI and Industry 4.0: machine vision for quality inspection and defect detection, predictive maintenance and digital transformation of industries
- Edge AI and applied large language models: AI on low-resource devices for health, education and agriculture
- Signal processing on the sphere: spatio-spectral analysis, Slepian functions and computationally efficient algorithms, with applications in geophysics, cosmology, acoustics and medical imaging
- AI, education and policy: climate-related educational disruptions, online education, and AI literacy and strategy programmes for leadership teams
Ongoing projects, for your reference:
- Impact of Green Energy for Cooking and Heating on Household Air Pollution and Health in Rural Communities of Pakistan, Wellcome Trust, with Aga Khan University (2026 to 2028)
- Low Emission Zones and Congestion Zone Design through GIS Emission Hotspot Mapping
- Understanding Climate-Related Educational Disruptions in Pakistan Through the Lens of Data, Inequality, and Policy, DARE-RC (FCDO)
- Edge AI Lab, with the National AI Hub at LUMS, supported by the Gates Foundation
- Erasmus+ CBHE RAPID project on online education in Pakistani universities (concluding October 2026)
- Industry collaborations in machine vision and digital transformation with Tetra Pak and Bulleh Shah Packaging
