Position description

A Postdoctoral Scholar position is available in the Rodriguez-Verdugo lab in Department of Ecology and Evolutionary Biology at the University of California, Irvine

We are seeking a highly motivated and independent postdoctoral scholar to work on an NSF-funded project investigating the role of cross-feeding interactions in the formation of new species in microbial communities. Using a two-species consortium composed of Acinetobacter johnsonii and Pseudomonas putida,

The successful candidate will (1) assess the conditions promoting phenotypic and genotypic divergence by evolving species under lab conditions; (2) characterize fitness tradeoffs and test frequency-dependence selection; and (3) assess coevolution and divergence by tracking the fate of adaptive mutations in populations. To achieve this, the candidate will employ a combination of experimental evolution, physiological assays, whole genomes and population sequencing, and reciprocal invasion experiments.

The postdoc will work directly with Dr. Alejandra Rodriguez-Verdugo in the Department of Ecology and Evolutionary Biology at UC Irvine. The successful candidate will work in a dynamic, inclusive, and collaborative research environment to advance the field of microbial ecology and evolution. There will be opportunities to mentor graduate and undergraduate students. The initial appointment will be for 2 years.

Application due date: Postdoctoral candidates are encouraged to apply by February 16, 2023, but the position will remain open until filled.
Start date: Flexible, ideally between April 2023 – June 2023.

The primary responsibilities of this position include:

  1. Conducting laboratory experiments (~40%), including evolution experiments, physiological assays (e.g. growth performance assays, biofilm assays…), and competition fitness assays.
  2. Analyzing data (~25%), including physiological and sequencing data, using R and Matlab, among others.
  3. Writing and presenting research results (~25%) Draft and submit manuscripts for publication in peer-reviewed scientific journals: present results at professional meetings, conferences, and seminars.
  4. Student mentoring (~10%) Mentor undergraduate and graduate students in related research.

Qualifications: The successful candidate is expected to have a PhD. in the following or related fields: microbial ecology, evolutionary biology, molecular microbiology, and ideally, will have experience in microbial experimental evolution, synthetic communities, and whole genome sequencing.
