Dr Ruzana Sanusi

Ruzana’s research sought to improve our understanding of the relationships between urban trees and human health and well-being.

Her studies investigated the connection of microclimatic conditions and human thermal comfort with dense, sparse and no canopy cover for different tree species.

In addition, it explored the physiological and morphological responses of different tree species to drought and heat stress alone or in combination, thereby investigating leaf senescence and the opportunity to manage this through supplementary and well-timed water provision.

This study provided insight into selection and management of urban trees to maintain and optimise their ecosystem service benefits under future harsh climatic conditions.

Her research explored the following questions:

  1. How does high tree canopy cover affect Human Thermal Comfort in a streetscale perspective?
  2. Do differences among tree species influence Human Thermal Comfort below?
  3. What is the physiological and morphological effect of drought and heat stress alone or in combination for young street trees?

Ruzana is now a Senior Lecturer in the Universiti Putra Malaysia’s Department of Forest Management in the Faculty of Forestry.
