Assistant Unit Leader of the NY Cooperative Fish and Wildlife Research Unit and Associate Professor Courtesy, Natural Resources and the Environment
I am a quantitative fisheries ecologist. I aim to address information needs to support marine and aquatic natural resource management. Work in my program focuses on applied statistics and modelling, complemented with field work on aquatic and marine ecosystems ranging from tropical to subarctic environments. Requisite with the joint social-ecological dynamics of natural resource systems, our work spans both ecological and socioeconomic facets of ecosystem management.

My research program integrates quantitative science + ecology + socioeconomic research to advance solutions to marine and aquatic ecosystem management problems ranging from local case studies to oceanscape scales. Our work encompasses four core themes that advance ecosystem management: 1) Population ecology to support species management, 2) Disturbance ecology to assess the response of ecosystems to anthropogenic x natural perturbations, 3) Social-ecological systems management, and 4) Quantitative ecological tool development. We predominately work in fishery systems, with additional research on marine mammals and aquatic invasive species including round goby (a fish), Elodea (a plant), and hippos (in Colombia).
Natural resource systems are driven by people and nature. We collaborate across disciplines to advance solutions to ecosystem management problems. Recent examples of multidisciplinary work in our group include:
- Fisheries science + marine ecology + computer science to identify strategies for Alaskan fishing communities to adapt to climate change
- Aquatic ecology + computer science to identify optimal strategies to conserve or restore riverscape connectivity
- Statistics + genetics to advance novel population assessment tools for fish and wildlife
- Conservation + finance to advance flows of resources for global biodiversity conservation through double bottom line investments that achieve both ecological and financial returns.

Seafaring drones soon will allow Cornell scientists to examine the abundance and distribution of forage fish – like zooplankton and shrimp – that nourish species higher on the food chain.
