Postdoc- Evolutionary Comparative Genomics
A 3-year PDRA is available in my lab to study the evolutionary genomic effects of changes in reproductive mode. Please see Research Openings page.
Postdoc- molecular analysis of parasitoid networks
Applications for this post are now closed. (A 2-year postdoc is available .. this project will be to use modern DNA techniques to investigate agricultural food webs, focussing especially on the interaction of parasitoid wasps with aphids and leaf miners). I will advertise another postdoc (bioinformatics and molecular evolution) shortly. Please see Research Openings page.
The Lunt Lab
I am an evolutionary geneticist at the University of Hull, UK. My lab uses phylogenetic and bioinformatic approaches to better understand genomes, evolutionary processes, and biodiversity.
Comparative Genomics
A main interest of my lab is in the processes that determine genome content, structure and change. To what extent do the primary forces of evolution (recombination, effective population size, mutation and natural selection) cause differences in genome content between different taxa and lineages of life. I explore these topics by comparative phylogenetic analysis of [...]
DNA sequence analysis
Most of my research projects involve evolutionary analysis of DNA sequence data, from phylogenetics to comparative genomics. Although phylogenetic approaches are widespread in many areas of biology they are largely underused for very large-scale sequence datasets and the analysis of genome-scale data.
Phylogenetics and Phylogenomics
Much of my research takes a phylogenetic approach to biological questions. I am especially interested in very large scale analyses and tools to automate the path from sequences to annotated trees. The image is Darwin’s first evolutionary tree from his 1837 notebook.
Parasitoids, DNA barcoding, and food webs
We are applying sensitive DNA barcoding approaches to understand host parasitoid interactions in agricultural systems. We are now able to screen the host species of parasitoid wasps (e.g. aphids) for the presence of parasitoid DNA using rapid PCR techniques. These studies allow a different way to understand both food webs and natural control of agricultural [...]
Evolutionary comparative genomics
The enormous quantities of genomic data now available permit us to powerfully test hypothese of molecular evolution. Perhaps because of the amount of data available comparative analysis of whole genomes is also challenging.We have developed a range of bioinformatic pipelines to facilitate our studies and are taking comparative phylogenetic approach to understanding genome content [...]
Genomics and asexual reproduction in nematodes
UPDATE Feb 2012: I will shortly be advertising for a 3 year postdoc to study reproductive mode and genome evolution. Please see Research Openings page. Root Knot Nematodes of the genus Meloidogyne are some of the world’s most important crop pathogens. The genus contains a wide range of reproductive modes, with repeated transitions between some [...]
Gene copy number variation in adaptive radiations
We are studying gene copy number variation (CNV) in adaptive radiations of cichlids. A fundamental question in biology is what type of genomic changes underlie local adaptation and species radiations. Cichlid fish radiations in the African Great Lakes show extraordinary levels of speciation and ecological diversification compared to their close riverine relatives. Despite a [...]
