Matt Burgess (PI)

I am an Assistant Professor in Environmental Studies, with a courtesy appointment in Economics. I am also a Fellow of the Cooperative Institute for Research in Environmental Sciences (CIRES), the Director of the Center for Social and Environmental Futures, and a Faculty Fellow of the Bruce D. Benson Center for the Study of Western Civilization. Starting in Fall 2024, I will be an Assistant Professor of Economics and a Presidential Fellow at the University of Wyoming.
My research interests are broad, but these days largely focus on exploring possible economic growth futures and their implications for the environment and society, strategies to reduce political polarization of environmental issues, and mathematical modeling of human-environment systems. I use a combination of mathematical and computer modeling, data synthesis, and collaboration with stakeholders, in order to make conceptual advances and link them to practice.
I spend most of my spare time with my wife and two sons--activities typically include anything involving planes, buses, trucks, and bouncy balls. My other hobbies include music, basketball, and golf.

Kath Landgren (CIRES Postdoctoral Visiting Fellow)

I am a CIRES Postdoctoral Visiting Fellow. I am interested in mathematical models as the interface of mathematics and the real world. I build and work with models of varying complexity. Prior to joining CU, I received my PhD in Applied Mathematics from Cornell University. I've used dynamical systems models to study a wide range of phenomena -- from voter turnout to planets beyond our solar system. My interest in both climate science and opinion dynamics brought me to CIRES. I am bringing these interests together by building a model of how public support for climate policy can be influenced by migration and strategic investment in clean energy.  I am interested in investigating strategies to overcome political polarization in the U.S. I am passionate about complex systems, open science, and interdisciplinary research.
In my free time, I am usually weightlifting, skiing, hiking, playing board games, and hanging out with my cat.

Ryan Langendorf (Postdoctoral Scholar, co-advised by Dan Doak)

My dream is to help people live empirically, making decisions with data rather than principle or intuition. We as a society need to debate desired outcomes rather than their causes. I want to help more than anything. This is why I study causality. What is causality? Don’t worry, you are not alone. There is no single operationalized definition of it, and I would argue causality is a metaphysical concept for our intuition of the apparently mechanical interactions we experience all around ourselves. Then, perhaps more to the point, I reconstruct networks using time series. 
How did I wind up building causal networks? Lots of chance and luck. You need only look to my identical twin brother to see how random our paths through life can be. I grew up with him in Chicago before studying in Maine. I then meandered through research gigs in Anchorage, Missouri, Arkansas, and Nevada before coming to Colorado and the Doak lab for a PhD studying ecosystems. But, I am actually drawn more to questions than any particular system, so since graduating I have expanded the kinds of data I work with. At Arpeggio Biosciences I use snapshots of nascent RNA transcription to understand the regulatory functioning of non-coding regions of our genomes in genetic diseases. And now, in the Burgess lab, I am studying the causal autonomy of social systems. We have tremendous troves of high fidelity spatiotemporal observational data on ourselves and our societies, but too many features are coupled such that variables can be combined into compelling stories on the causes of our roles in everything from extinction to poverty to extreme weather. These stories are particularly effective because people tend to side with the norms of their social group over scientific evidence. I try every day to create and disseminate tools able to explain the causes of these most daunting challenges we all face.

Christian Suarez (Ph.D. Student - Environmental Studies 2023-present)

I am a current PhD student at CU Boulder in the Environmental Studies Department. Originally from Miami, FL, I received my Bachelor’s in both Economics and Sport Management at the University of Florida, then went on to receive my Master’s in Economics from Vanderbilt University. Throughout my time at both universities I held various positions ranging from interning with the United Nations Economic Commission for Europe in Geneva, Switzerland, to working on the video staff for each school’s college football team. Following my Master’s I moved back to Miami and worked in the private equity space, most recently for a non-profit angel investment group. My research interests include, but are not limited to, political polarization of environmental policy, sustainable public land management and the intersectionality of environmental and economic impact of public land use.
I currently live in Denver with my wife Emily, a resident physician at CU Anschutz, as well as our two miniature schnauzers. In my free time I love to travel, hike, read, play sports, listen to podcasts, play with my dogs, and watch my favorite sports teams.
