Graduate Students

Mohamed Yakub
Mo has been investigating the how urban environments affect evolution of plant populations.  He will be defending soon and has accepted a job coordinating and developing outreach activities for the UMN Borlaugh-Stakeman Center.  Mo also was one of the founding members of Market Science (I serve as faculty advisor), which for the past couple of years has been bringing hands-on science activities to a local farmers market.

Derek Nedveck
Derek is working on local adaptation in legume-rhizobia symbisosis in Minnesota populations of Lotus

Amanda Gorton (co-advised with David Moeller)
Amanda is investigating the factors that shape the scale of local adaptation, using urban and rural populations of ragweed as an empirical system

Joseph Guihlin 
Joseph joined the lab with extensive computational experience and expertise.  He has been providing informatics support fot the Medicago HapMap project while working on a dissertation that integrates development of computational tools, the role of copy number variation in phenotypic variation in Medicago, and the population genomics of Sinorhizobia.

Post-docs

Liana Burghardt
Liana is working on a couple of things related to linking genomes to phenotypes and selection: how the genetic identify of symbiotic partners affect gene expression in Medicago, the role of structural variation in gene expression, and GWAS and population genomics in Sinorhizobia.  She earned her PhD working with Kathleen Donohue.  Her web site is far more informative than this blurb.


Former Members

Former Post-docs

Jeremy Yoder - currently a post-doc with Sally Aitken at UBC
Jeremy mostly focused on using genomic data to understand local adaptation and the evolution and population genetics of symbiotic interactions.  While in the lab he also was involved in using association genetics to identify targets of local adaptation and investigated the phylogenomics of the genus.  He also was active in communicating science (and related issues) through The Molecular Ecologist and Nothing in Biology Makes Sense

John Stanton-Geddes - currently a data analyst in the private sector.
John worked on sequence-based GWAS analyses as well as the potential for using hihg-density markers to estimate heritability in natural populations.  

Timothy Paape - currently a post-doc at University of Zurich
Tim worked on population genomics (recombination, selection) and association genetics in Medicago.

Antoine Branca - Maître de conférences (Assistant Professor), Université Paris 11, Orsay
Antoine worked on population genomics of Medicago and Sinorhizobia.

Stephen Keller - Assistant Professor, University of Vermont
Steve used population genetic approaches to investigate the demographic history and local adaptation in balsam poplar.

Maurine Neiman - Associate Professor, Department of Biology, Univirsity of Iowa
Maurine  spent a year in my lab investigating the molecular evolution and population genetics of protease inhibitor genes in Poplar.

Jennifer Lau - Associate Professor of Plant Biology, Michigan State University, Kellogg Biological Station
Jen collaborated on research investigating potential evolutionary impacts of increasing concentrations of atmospheric CO2 concentrations.

David Moeller - Associate Professor, Department of Plant Biology, University of Minnesota
Dave collaborated on research investigating the molecular evolution of plant immunity genes and characterizing the population structure of teosinte (Zea mays ssp. parviglumis) and was the lead on work investigating the ecological and evolutionary limits of species range expansion.

Former Graduate Students

Brendan Epstein (co-advised with Mike Sadowsky) -- now a post-doc with Andrew Storfer at Washington State
Brendan is investigating the population genomics of rhizobia.  In addition to standard SNP-based surveys of diversity he is currently exploring the evolutionary history of duplications and horizontally-transferred genes.  

John Stanton-Geddes (coadvised by Ruth Shaw) -- data analyst in the private sector
John's dissertation investigated the ecological genetics of habitat specialization and range limitations.

Katy Heath - Assistant Professor, Department of Plant Biology University of Illinois
Katy's dissertation research investigated evolutionary forces that may maintain genetic variation in the Medicago-Sinorhizobia symbiosis.

Laurie Stone - MS (coadvised by Ruth Shaw)
