Sebastian HöhnaI’m a computational biologist with focus on Bayesian phylogenetic inference. Natural selection by means of adaptation and genetic inheritance are key principles in evolutionary biology. Evolutionary relationships are commonly depicted by phylogenetic trees. Using phylogenetic methods we can learn about the evolutionary history of species and the processes that have contributed to present diversity. I’m developing statistical and computational methods to infer phylogenies from molecular sequence data. These methods additionally identify periods of adaptive genetic evolution at lineage or genes. Furthermore, I develop mathematical models to study macroevolutionary patterns, such as, diversification rate variation over time and among lineages and episodes of global mass extinctions.
Allison HsiangMy research uses statistical modeling, Bayesian inference, Big Data, and machine learning to understand morphological evolution and macroevolutionary patterns and processes. I am particularly interested in bringing a ‘next-generation’ approach (e.g., high-throughput automated data generation) to studying fossils and morphology in a phylogenetic context. I am also interested in the interplay between morphology and genetics, including methodological considerations during phylogenetic inference.
Luiza FabretiI'm interested in computational and evolutionary biology. Specially, improving the way we model evolution. My research involves Bayesian phylogenetic inference and underlying topics such as, model selection, testing the adequacy of the most commonly used substitution models and assessing convergence of the Markov Chain Monte Carlo.
Ronja BillensteinI’m a biologist working on statistical methods for inferring the evolutionary history of closely related populations. These methods are based on coalescent theory and a mutation process. I am using simulated as well as empirical data to test and to validate these methods, hoping to provide an accurate, powerful and computationally feasible approach.
Killian SmithI am a computer scientist working with Bayesian phylogenetics and substitution models, and am interested in applying concepts and theory from CS in this domain. In my research I will be exploring covarion models, mixture models, and Markov modulated continuous Markov chains (MMCMC), and their effects on phylogenetic tree construction. Some of my other research interests include type theory, functional programming, de novo sequencing, multiple sequence alignment, genome assembly, and machine learning.
Bjørn T. KopperudI am an evolutionary biologist who is interested in estimating speciation- and extinction rates from phylogenetic trees. Previously, it has been common to test the support of competing hypotheses by testing one or a few factors at a time. In my research I will develop a more general framework for estimating diversification dynamics, such that setting up joint or combined models becomes more feasible. My other interests include data mining using natural language processing, brain size evolution and phylogenetic comparative models of adaptation. My favorite organisms are bryozoans and ruminants!
