Luis Avila

Luis is a staff computational biologist working on inversion polymorphisms and recombination rate variation in maize landraces and teosinte.




Dan Gates

Dan is a postdoctoral scholar who studies adaptive introgression and local adaptation in maize landraces as part of the HiLo project.




Asher Hudson

Asher is a graduate student in Population Biology working on herbivory and local adaptation in teosinte.




Caryn Johansen

Caryn is a graduate student in the Plant Biology Graduate Group, coadvised by Dan Runcie. Caryn is interested in local adaptation in maize and modeling the genetic architecture underlying quantitative traits.




Emily Josephs

Emily is an NSF plant genome postdoc working on polygenic adaptation in plants, in collaboration with Graham Coop and Julin Maloof.




Anne Lorant

Anne has worked as the lab manager since 2012. In addition to running the show, she works the magic to get us from seed to .bam. Anne is concurrently doing a PhD in teosinte evolutionary genetics with Maud Tenaillon.




Scotty Mahan

Scotty is a genetics major, working with Jeff and Anne to develop genotyping and assignment methods.




Niki Mahmoudzadeh Niki is a 3rd year student working with Dan Gates on highland adaptation.





Wenbin Mei

Wenbin is a postdoctoral scholar who works on the population genetics of copy number variants and inversions in maize and teosinte. Wenbin is also part of the maize diversity project.




Anna O’Brien

Anna is a graduate student in Population Biology, coadvised by Sharon Strauss. Anna works on the coevolution of teosinte and rhizosphere biota along elevational gradients in Mexico.




Ellen Osborn

Ellen is an undergraduate researcher majoring in Global Disease Biology. She is working with Michelle Stitzer on the population genetics of transposable elements in maize and teosinte.




Jeffrey Ross-Ibarra

Jeff is a Professor in the Department of Plant Sciences and a faculty member of the Center for Population Biology and the Genome Center. He started at UC Davis in 2009.




Michelle Stitzer

Michelle is a graduate student in Population Biology, working on the population genetics of transposable elements in maize and Arabidopsis as part of the maize diversity project.




Markus Stetter

Markus is postdoctoral scholar working on domestication and adaptation in polygenic traits in maize and teosinte.




Dianne Velasco

Dianne is a graduate student in Integrated Genetics and Genomics. She studies domestication and evolution of peaches, almonds, and their relatives in the genus Prunus.
