Ruohan is currently a Research Fellow working on the CoolNUS-BEAM initiative, supporting NUS's efforts to strengthen campus climate resilience and improve outdoor thermal comfort. Her work focuses on data analysis and developing predictive models integrated with the campus digital twin for heat hotspot identification and mitigation evaluation. She also conducts campus-scale microclimate simulations and field experiments (e.g., cool pavements) to assess and validate cooling strategies. As a CAAS-certified UAV pilot, she is responsible for drone-based (UAV) data collection to support microclimate monitoring and high-resolution site assessments.
She obtained her PhD from the Department of the Built Environment, National University of Singapore. Her doctoral research investigated vertical profiles of air temperature and wind speed in high-density tropical urban environments, combining urban morphology, CFD simulation, and machine learning to reveal height-dependent mechanisms and inform evidence-based cooling strategies.

Research Interests:

• Microclimates in built environments

• Thermal environments influenced by urban morphology

• Machine learning applications in urban cooling strategies

• Drone technology for environmental data collection

• Urban Heat Island (UHI) mitigation strategies
