Welcome to the Lab

Evolution is the fundamental organizing principle of biology and phylogeny is the fundamental framework for understanding evolutionary history. Reconstructing the Tree of Life has been a goal of biologists since Darwin first included his conception of a phylogenetic tree as the sole figure in On the Origin of Species. However, the recognized importance of accurately reconstructing evolutionary history now extends far beyond the confines of evolutionary biology. Historical evolutionary inference has become an integral component of research in molecular biology, genomics, medicine, conservation, agriculture, epidemiology, and even forensics.

Our lab evaluates, creates, and applies phylogenetic methods to some of today's most pressing questions.

The Brown Phyleaux Lab has experienced quite a bit of turnover in the past few months. Several excellent and talented lab members have moved on to explore new frontiers. Chelsea Kliebert, an undergraduate researcher, graduated from LSU in May 2014 and is now pursuing a Ph.D. in the Chemical and Systems Biology graduate program at Stanford. Jeremy Ash, a research associate, started working in the lab in February 2014 and then began work on a Ph.D. in Bioinformatics at North Carolina State in August.

Congratulations to Brad Nelson, who recently became the first Master's graduate from the Brown Phyleaux lab. Brad's thesis includes two very nice chapters on improving Bayesian branch-length inference by using informed priors and applying posterior predictive approaches to assess the reliability of an inferred squamate phylogeny.

Postdoc Position Available

May
08

A postdoctoral researcher position is available in the computational evolutionary biology lab of Jeremy M. Brown. This position is part of a project funded by the National Science Foundation to develop and apply a suite of related statistical approaches for assessing the fit of stochastic models to sequence and trait data. The goal of this work is to identify when phylogenetic and comparative inferences might be compromised by poor model fit.

Welcome to Jeremy Ash

Feb
08

Jeremy Ash, a recent graduate of the University of Texas at Austin, has joined the lab as a Research Associate. Jeremy will be working on a project funded by the NSF Advances in Biological Informatics program to explore network-based approaches for characterizing and quantifying phylogenetic signal in large sets of trees. This project is collaborative with Jim Wilgenbusch, Kyle Gallivan, Wen Huang, Guifang Zhou, and Melissa Marchand at Florida State University.

LSU Computational Biology Seminar for Undergrads - 1/22

Jan
21

The spring 2014 LSU computational biology seminars for undergraduates will kick off tomorrow, Jan. 22nd. The first seminar will be given by Dr. Dorel Moldovan from LSU's Dept. of Mechanical and Industrial Engineering. Dr. Moldovan will be speaking about "Molecular Dynamics Simulation Studies of Surface and Interfacial Phenomena in Biomolecular Systems".  The talk will be preceded by food in the Life Science Annex Atrium at 5 and will then run from 5:30-6:30 in the Life Science Annex Auditorium.

Computational Biology Seminar Series for Undergraduates

Sep
17

A new monthly seminar series on computational biology has just begun at LSU.  These seminars are targeted towards undergraduates and intended to stimulate student interest in the intersection of biology and computation.  This semester, students will learn about exciting research being done by new faculty here in LSU's Dept. of Biological Sciences.  Dr. Brown kicked off the series on Sept. 9th with his talk, titled "Models, Genomes, and Trees: Computational Inferences of Evolutionary History".  The next talk will be given by Dr.
