Translating Domain Knowledge to Testable Models
I am interested by the challenge of translating domain expertise into testable statistical frameworks. Especially in biology where the difficult-to-code observational / experimental findings often are left out of the modelling process.
History and Future of Evolutionary Biology
The convergence of past and present contributors in the field, their cultural context, and the resulting assumptions, biases, and inferences that shape evolutionary thinking has always interested me. I believe that fully acknowledging and reconciling this historical legacy with the present is crucial for advancing evolutionary research beyond the field's active justification of systemic racism, eugenics, and discrimination. I hope to eventually expand my interest in this convergence into a more formal research effort.

Dissertation Overview
My dissertation explores the intersection of complex traits, methodological approaches in macroevolution, and the evolution of bird migration. It is structured around three key questions:
- How effectively do our current methods identify and analyze 'complex' biological traits when simplified into discrete states?
- To what extent can migration in birds, as a complex trait known to have many axes of continuous variation, be adequately represented by discrete states?
- What can we gain by pushing the limits of discrete state analysis in the context of complex traits?
Quantifying Migratory Behavior with eBird
The study of avian migration presents a distinctive challenge due to the many ways a bird can be considered a 'migrant', most of which are difficult to measure directly. This is a common problem in comparative biology, as many times the traits that researchers are interested in are difficult to wrangle into a simple dataset.
Developing effective methods to measure and model these difficult-to-measure axes is essential for understanding the evolution of migration as a trait over long time scales, as well as understanding the relationship between migration and other traits.
Using Hidden States Markov Models
The first part of my dissertation focuses on the efficacy of Structured Hidden Markov Models (SHMMs) in identifying threshold traits - discretized traits with underlying one-dimensional continuous variation. This approach allows us to test whether a discrete trait is best described as a one-dimensional threshold trait, even when only discrete data are available.
