Our lab was featured in a story about getting science done during a pandemic. On the written story you can see a picture of Fernando Diaz (postdoc) in the field in Organ Pipe National Monument, a picture of some of our fly cages taken by Carson Allan (lab manager), and the reference to being in the lab around the clock was to the experiments that Kyle Benowitz (postdoc) did.
On June 15, 2020 we officially started our work on uncovering the genetics of Bt resistance in the agricultural pest Helicoverpa zea (Corn earworm, CEW). This work is in collaboration with friends and great colleagues from the Department of Entomology at the University of Arizona, Bruce Tabashnik and Yves Carriere, and from the USDA ALARC, Jeff Fabrick.
Today Tierney Shaible did a wonderful job in presenting her impressive amount of work on D. mojavensis and how they adjust at the behavioral, life history, physiological and transcription level to the summer conditions of the Sonoran Desert.
Stay tuned for the two manuscripts that will come out of her Thesis work.
Working on ecologically interesting species is a powerful way to link patterns of variation from genes/genomes to organism level traits to the selective forces shaping it. To facilitate this, having a chromosome-level genome assembly is very helpful. In this paper we outline how this is an attainable goal. We provide a step-by-step guide for investigators that work on ecologically exciting species, but do not have a vast computational background.
Happy to see our BMC Genomics paper out. This is the first ever paper that examines the pattern of genomic evolution across the four cactus host populations of Drosophila mojavensis. So glad to see all of Carson’s hard work finally in print.

Our paper looking at the underlying genetic architecture of locomotor behavior in Drosophila mojavensis using bulk segregant analysis is out in G3 Early Online. http://www.g3journal.org/content/early/2019/03/29/g3.119.400036. Kyle Benowitz and Josh Coleman put a tremendous amount of effort in this study. Awesome work.
Very excited to say that we have several other exciting studies on the genetic architecture of behavior, life history and morphological traits in D. mojavensis coming!!!
Very happy to be notified that our NIH proposal on the genetic basis of infertility in collaboration with Jeremy Bono (University of Colorado, Colorado Springs) will get funded.
Graduate student opportunities in evolutionary genomics of adaptation and speciation at the University of Arizona
The Matzkin Lab (www.matzkinlab.org) at the University of Arizona, Department of Entomology is currently recruiting graduate students (PhD and MS) to join our diverse lab. Our lab has several themes focusing mostly on the exciting cactophilic Drosophila system. Among the ongoing projects are:
– Genomic evolution across cactophilic Drosophila.
– Quantitative genetics of behavioral strategies, life history characteristics, morphology associated with local ecological adaptation
– Ecological genomics of adaptation in cactophilic Drosophila (cactus host chemistry, nutrition, desiccation, thermal stress, aestivation, etc.)
– Evolutionary genomics of plasticity and transgenerational effects
– Genomics of speciation and the evolution of reproductive incompatibilities
The fact that we are located in the Sonoran Desert also facilitates field focused projects. If you are interested in these or other related topics please contact Luciano Matzkin (firstname.lastname@example.org). Graduate students can apply via the Entomology and Insect Science (EIS) Graduate Program (https://insects.arizona.edu/) or the Ecology and Evolutionary Biology Graduate Program (https://eeb.arizona.edu/grads). The application deadline for both programs is December 1st.
The Matzkin Lab at the University of Arizona, Department of Entomology (www.matzkinlab.org) is currently recruiting a postdoc to work on a variety evolutionary genomics projects focusing on the genomic diversification of cactophilic Drosophila. I am seeking a highly motivated and creative individual with strong computational and evolutionary genetics skills to join our evolutionary and ecological genomics lab. Postdoc will be based at The University of Arizona, Department of Entomology and will have the opportunity to interact with investigators at the BIO5 Institute and Department of Ecology and Evolutionary Biology.
The postdoc will be involved in all research aspects of the assigned projects and will have the opportunity to develop projects in consultation with Dr. Matzkin. Critical and independent thinking is very important for this position, as well as having the ability to analyze data, develop pipelines and genomic tools, write manuscripts and proposal writing. Postdoc will interact with the graduate and undergraduate students in the Matzkin lab at the University of Arizona as well as having the opportunity to be involved in outreach activities.
The postdoctoral researcher will be required to maintain up-to-date records of all experiments, analysis and data collected. The postdoc will report to Dr. Matzkin on a weekly basis on the progress of projects and experiments. The postdoc will be required to have an active participation in writing publication manuscripts based on the research produced in the lab. The postdoctoral research will also be responsible in creating and maintaining a database of the genomic data as well as assisting in creating a web platform to disseminate the information to the broader community.
The candidate is expected to have a PhD in evolutionary biology, genomics, computational biology or related field. Postdoc must have excellent writing, communication and critical thinking skills with at least 1-3 publications (in print or submitted). Prior experience working with Drosophila a plus but not necessary. The position is available to start immediately. Funding for the position is for one year, with the possibility of extension pending additional funding.
Apply at https://uacareers.com/postings/29309. (Posting number P20575). You will need to submit a 1) cover letter briefly outlining the candidate’s fit to the position and future goals 2) curriculum vitae 3) contact information (email and phone) for three references, preferably including doctoral advisor and/or postdoctoral advisor (if relevant) and 4) no more than three relevant publication PDFs. Please contact Luciano Matzkin (email@example.com) if you have additional questions about the position.

After several months, the lab renovations of our molecular lab are finally complete. I love my new blue floors with red trim (which match our new red lab chairs!!!). See the progress of the transition below.
