Shaw Lab Community Mission Statement

​Ecological theory aims to clarify the links between mechanism and pattern in the natural world by using conceptual and mathematical models. We leverage theoretical approaches to develop an understanding that transcends particular empirical systems, which is especially valuable when answers rely on phenomena that cannot be directly observed in nature. Tackling scientific questions in light of the global challenges we face requires diverse perspectives; science needs all of us! We believe that anyone can do theory regardless of mathematical background or skills. In our lab, we develop our own theory and we foster a broader community that helps people do theory in their research. We also aim to improve theory literacy through developing frameworks, facilitating communication between empiricists and theorists, outreach, and teaching.

My research uses math to understand the similarities – and reconcile the differences – across species. In particular, I am fascinated by movement: a behavior found in all organisms that is often adaptable on short time scales, and influences the ecology and evolution of populations. I am interested in the factors that drive organisms to move, the consequences of movement, and feedback between these two. Generally, I construct either analytic or simulation models, which are fantastic tools for studying the interface between ecological and evolutionary processes.

During my PhD, I hope to explore the role of facilitative interactions for driving novel advancements in biological organization. By combining mathematical modeling approaches in the Shaw Lab with experimental evolution of microbes in the Travisano Lab, I hope to contribute to greater clarity on how simple things gained incredible complexity over billions of years on earth.

I am interested in using math to study how species interactions shape ecological communities. My particular focus is on interactions in which organisms modify environmental conditions and thereby indirectly influence other species. Using theoretical models, my work explores how this species-environment feedback shapes biodiversity as well as the spatial and temporal patterns of ecological communities.

I am interested in using theoretical tools to understand how populations spread through changing environments. Previously, I have used simulations of dispersing species to investigate how their interactions can impact whether they are able to coexist across space. I hope to continue learning how to apply these approaches to questions related to population dynamics and biodiversity.

Friendly hijabi girl (Yumna) smiling at the viewer ​ During my stay in the Shaw lab I want to gain a new way of thinking through understanding theoretical modeling and its applications. I will be expanding on an existing species interactions model by adding an environmental factor. This model will be investigated through the relationship between jellyfish, small fish, and ocean acidification.

Honarary / Visiting Lab Members

We are lucky to currently have a number of ‘friends of the lab’ who often attend lab meetings and otherwise enrich our lab culture:

Recent collaborators

Theory Group

In the past (from 2014-2022) our lab facilitated an informal theory and modeling lab group meeting, open to anyone in EEB, PMB and beyond. The aim was to create a forum for providing feedback on ongoing modeling work…and to sometimes make theory-related desserts.

Biological Theory Alliance (BioTA)

We co-founded (in 2015) and were a member (until 2024) of the University of Minnesota’s Biological Theory Alliance (BioTA), which aimed to bring together researchers who use conceptual and mathematical modeling to understand biology.
