Earth systems · Data · Decisions

From environmental change to resilient action.

HAO Lab combines environmental science, engineering, artificial intelligence, and optimization to understand risk and design better decisions for coupled human–natural systems.

Research pillars

Two connected questions guide our work.

01

Climate & Ecosystem Risk

How do flash droughts, heatwaves, wildfire, and water stress reshape ecosystem productivity, carbon exchange, and recovery?

  • Flash drought and heatwave impacts
  • Ecosystem water-use efficiency
  • Carbon and greenhouse-gas dynamics

02

Decision Optimization & Resilience

How can uncertain forecasts become transparent, robust, and actionable decisions for communities and engineered systems?

  • Stochastic and robust optimization
  • Risk assessment and early warning
  • Decision-support system design

How we work

Methods designed for complex systems.

We pair physical understanding with modern data and decision science. The goal is not only better prediction, but better choices under uncertainty.

Earth observation

Remote sensing, field observations, and multi-source data integration.

AI & uncertainty

Machine learning, model ensembles, and uncertainty quantification.

Process modeling

Hydrologic, ecosystem, and coupled human–natural system models.

Decision science

Operations research, stochastic optimization, and decision support.
