- Evaluate emerging simulation tools, certification frameworks, and regulations
- Lead office-wide sustainability initiatives with Research Group colleagues
- Engage in interdisciplinary brainstorming sessions across a wide range of topics, including building performance, environmental justice, human health, post-occupancy evaluation, and many others
