The Department of Ecology and Evolutionary Biology and the new Institute for Quantitative and Computational Biosciences (QCBio) at the University of California, Los Angeles are searching for a joint faculty appointment at the level of Assistant Professor. Candidates must have a PhD within the field of Biology, Microbiology and/or Computational Sciences. Quantitative and computational biologists working on the ecology or evolution of terrestrial or aquatic (including marine) microbiomes, microbial symbionts, and/or pathogens, at the level of populations or communities, are invited to apply. The competitive applicant will conduct conceptually oriented research that uses quantitative or computational approaches such as mathematical modeling, genomics/metagenomics, or network science. Research on naturally-occurring or laboratory systems will be considered, and experimental approaches and use of emerging technologies are encouraged. Review of applications will begin on January 15, 2017.
