Research Interests
How do landscapes that we design, especially urban landscapes, impact the health and wellbeing of people? My students and I examine this question by measuring exposure to varying landscapes -- the level of green infrastructure in neighborhoods, or the amount of nature on campuses, or the density of vegetation in urban spaces. We measure the impact of these places on people’s hormones, heart rates, brain waves, psychological states, and ability to pay attention.
