Start year: 2013
Interests:
Ecology, population dynamics, phenology, disturbance. I focus on how species traits mediate timing and abundance patterns. I'm broadly interested in animal responses to environmental change at the population level and how those responses vary in relation to individual and population traits. I've worked primarily with birds and butterflies. I work mostly with community science platforms reporting surveys (Pollardbase, Discover Life) and opportunistic observations (iNaturalist, eButterfly).
