The Department of Integrative Biology at UT Austin has two open positions for assistant professors, one in evolutionary biology and one in mechanistic processes. Please share. Apply here: apply.interfolio.com/193270
Two Assistant Professor Positions in Evolutionary Biology and Mechanistic Processes

Description
The Department of Integrative Biology at The University of Texas at Austin seeks to fill two faculty positions in the areas of Evolutionary Biology and Mechanistic Processes, broadly defined. We are looking for candidates who are advancing (1) evolutionary biology or (2) the mechanistic understanding of organismal processes. These positions will be filled at the level of Assistant Professor.


Qualifications
Candidates should be using innovative approaches in evolutionary biology and/or the mechanistic understanding of whole-organism processes. Mechanistic processes include, but are not limited to, behavior, biomechanics, cognition, physiology, and development. The phylogenetic scope of the Evolutionary Biology position may include eukaryotes, prokaryotes, viruses, and the scale may include individual molecules to entire ecosystems and beyond. Candidates for either position may employ experimental, theoretical, or computational frameworks, or a combination thereof. Special consideration will be given to applicants with demonstrated potential for integrating across our target disciplines. 

We seek applicants with a strong record of high-quality research, publications, potential for extramural funding, and a commitment to excellence in teaching and mentorship. A PhD or equivalent is required at the time of appointment, and postdoctoral research experience is strongly recommended.

Y'all - the Smithsonian is hiring three new curators - herpetology, ichthyology, and ornithology! Notably, this is a 2nd fish curator position - i.e., not the same as the one advertised last month. So if you applied for that one apply again. www.usajobs.gov/job/873849000
Curator of Vertebrates

Smithsonian’s National Museum of Natural History currently has openings for three early-career Research Curators in Vertebrate Zoology, one each from the disciplines of ornithology, herpetology and ichthyology. The Department of Vertebrate Zoology seeks candidates with demonstrated expertise in, and a commitment to, collections-based research centered on systematics and evolution of birds, reptiles, amphibians, and fishes. This includes the ability to pursue an original approach to systematics and comparative analyses using, for example, morphology, development, and/or molecular data, and showing evidence of broader impacts or applications in evolutionary biology and/or collections-based ecology, as demonstrated by a record of peer-reviewed publications.

Candidates must have demonstrated the ability to establish an externally funded research program and to contribute to the growth and curation of the collections. Research in the Department is supported by the Museum’s shared laboratories, including the Laboratory of Analytic Biology and the Scientific Imaging facility, among others. The Department’s scientific collections are the largest in the world for fishes, amphibians, and reptiles, and the third largest for birds.

These federal positions will be filled at the GS-12 level, with a starting salary of $102,415, and excellent benefits. The positions are permanent and require a one-year probationary period. 

The official announcement is posted on USAJOBS, where applications must be submitted.
https://www.usajobs.gov/job/873849000

Please be sure to read the announcement and instructions carefully, as the process of applying via USAJOBS is stringent and differs from applying for an academic position. This website offers helpful advice: https://serc.si.edu/careers/tips-applying-federal-jobs

Please contact the Search Committee Chair, Michael McGowen (mcgowenm@si.edu) or the Department Chair, Helen James (jamesh@si.edu) with any questions.
