I am an Assistant Professor of Conservation Science in the Department of Fisheries, Wildlife, and Conservation Biology at the University of Minnesota, and an Associate Fellow at the Institute on the Environment.

Sustaining both biodiversity and the benefits nature provides to people (i.e., ecosystem services) is a major challenge for scientists and managers. Achieving both goals is complicated by accelerating global environmental change. In response, my lab’s aims to (1) quantify the impacts of global changes, like disturbances, climate variability, and biodiversity change, on ecosystems, their functions, and their contributions to society; (2) understand how ecosystems provide benefits to people, how global change will alter these relationships, and how to best adapt conservation in response.

I combine global change ecology, community ecology, ecosystem ecology, and conservation science and uses quantitative tools from multiple disciplines, including both theoretical and empirical modeling approaches . My interests span multiple spatial scales and  ecosystem types (e.g., forests, marine and coastal ecosystems, grasslands), I analyze large-datasets from different scales (local, regional, and global), and I leverage quantitative tools from several disciplines (e.g., ecological theory, network theory, causal inference approaches from econometrics, decision science, and functional trait ecology). For example,  a major research interest is causal inference in observational ecological and social-ecological data. To learn more about my lab’s research, please visit the research page.

To tackle complex conservation and sustainability challenges, my lab leads and contributes regularly to collaborative and interdisciplinary teams that focus on synthesis science (e.g., working with other ecologists, biologists, sociologists, economists, geographers, applied mathematicians, computer scientists, and conservation practitioners). This work aims to inform conservation  strategies that will be robust to climate change and uncertainty.

My Ph.D. research in Ecology, at UC Santa Barbara, focused on the impacts of temperature variability and biodiversity on global fisheries yields and the extent to which managing for ecosystem services provides an economic incentive for conservation. I completed a concurrent MA in Economics at UCSB, advised by Drs. Christopher Costello and Dick Startz. As a post-doctoral associate at the University of Minnesota, I examined how climate change and extreme disturbances affects boreal forests and the ecosystem services they provide (co-advised by Peter Reich and Steve Polasky).

FW5121: Conservation Planning & Structured-Decision Making

Course descriptions and objectives:

Conservation planning and structured decision making (FW5121)

We are impacting our planet and the species and ecosystems on it at an unprecedented rate. This creates key policy challenges to conserve species, ecosystems, and the benefits they provide to people. But, how do we decide what is the best way to tackle these challenges? How do we do this in a world with limited resources (time, money) for conservation, and multiple stakeholders with different objectives? How can we make systematic decisions to get the biggest bang for our conservation buck? To address these questions, this course will cover key topics and concepts in conservation planning and provide exposure and hands-on experience with techniques for conservation plans and decisions. We will cover topics ranging from protected areas, restoration, ecosystem services, and climate change to structured decision-making, adaptive management, and return on investment. The course has a lecture and in class computer lab component. This course will present structured approaches to problem-solving and decision-making from conservation perspective, and students will leave with tools for structuring and solving complex environmental problems. Therefore, this is a foundational course in conservation planning but will also provide students will a tool-box to formulate and solve complex problems in environmental management more broadly and in life.

Prerequisites: Senior or graduate standing, or permission of instructor. Recommended: One course in ecology, environmental science or permission of instructor.

Objectives

  • Analyze and understand challenges for conservation in our current times
  • Apply and understand key concepts and principles in conservation planning, and their applications in real-world settings
  • Apply current approaches and techniques to solve complex conservation challenges and decisions
  • Evaluate key scientific literature in conservation planning through reading and analyzing scientific papers, and applying this knowledge to lab assignments designed as hypothetical conservation plans and decisions.

Sustainable People, Sustainable Planet (SUST 3003)

Sustainability recognizes that social equity, environmental integrity, and economic prosperity are all worthy goals, but that these goals compete, so that it is impossible to maximize all three of them concurrently. Some objectives of sustainability are therefore realized at the cost of other equally valid objectives. Sustainability is inherently ethical and requires decisions to be rooted in moral principles and value judgments. In Sustainable People, Sustainable Planet, we will approach sustainability from multiple viewpoints and explore various models for understanding and integrating these value judgments. We will demonstrate, by utilizing a variety of real-world case studies, the conflicts and trade-offs that occur from trying to put sustainability into practice.

Prerequisites: Sustainable People, Sustainable Planet is intended for sophomores and above. There are no formal prerequisites, but you should have previous exposure to critical reading, writing, and thinking (e.g., freshman writing). The course currently satisfies the CLE elective theme for Environment, and is also the introduction course for the Sustainability Studies Minor.

Objectives:  

  • Describe, explain, interpret, and summarize basic facts and concepts involved in the study and practice of sustainability
  • Connect the diversity of perspectives involved in sustainability, including history, philosophy, psychology, economics, politics, religion, culture, science, and technology
  • Examine, and discuss competing economic, social, and environmental goals
  • Collaborate with others to find common ground in the search for sustainability
  • Appraise, assess, and evaluate real-world case studies involving sustainability trade-offs
  • Incorporate concepts of sustainability into your own life
