4-year postdoc position: Pinniped ecological and evolutionary genomics
With Dr Joe Hoffman (Bielefeld University, Germany) and Dr Jaume Forcada 
(British Antarctic Survey, UK)

An outstanding opportunity is available for a postdoctoral researcher to work 
on the ecological and evolutionary genomics of fur seals.  The position is 
available in Joe Hoffman's research group (www.thehoffmanlab.com) in the 
Department of Animal Behaviour at Bielefeld University.  It runs from early 
2018 to the end of 2021 and is funded by the German Research Foundation (DFG) 
within the recently approved collaborative research centre (SFB/TRR 212) 
entitled: A Novel Synthesis of Individualisation across Behaviour, Ecology and 
Evolution: Niche Choice, Niche Conformance, Niche Construction (NC3).

The project:  The postdoc will exploit and continue to build upon an 
exceptionally detailed long-term study of Antarctic fur seals (Arctocephalus 
gazella) at Bird Island, South Georgia.  High quality genome and transcriptome 
assemblies have already been generated and microsatellite and high density SNP 
data will be available for ≤7000 marked individuals spanning a time series from 
the mid 1980's to the current day.  The aim of this project (sub-project A01 of 
the collaborative research centre) is to determine how fitness variation is 
shaped by interactions between individual genetic quality (inbreeding) and the 
social environment within breeding colonies.  Highly detailed observational and 
biometric time-series data will be collected from mother-offspring pairs in two 
neighbouring colonies of high and low social density.  The mechanistic 
underpinnings of fitness variation will then be dissected apart using a novel 
combination of endocrinological and immunological profiling, high-density SNP 
genotyping, transcriptomics and genome-wide methylation profiling.  This will 
generate unprecedentedly detailed insights into fitness variation in a wild 
vertebrate, with major implications for understanding ecological and 
evolutionary dynamics as well as adaptation to climate change.

The applicant: We seek a bright and highly motivated postdoc with a strong PhD 
in a relevant topic (e.g. population genetics, behavioural, evolutionary or 
conservation genomics, bioinformatics, animal behaviour, behavioural ecology).  
A deep understanding as well as extensive practical experience of working with 
high-throughput sequencing data (including RADseq, transcriptomic and 
whole-genome resequencing data) is highly desirable, as is proficiency in 
writing custom scripts and working in Unix and R.  Experience of working with 
large-scale, long-term datasets from wild animal populations would also be a 
bonus.  As the postdoc involves two field seasons at South Georgia in the South 
Atlantic, experience of fieldwork with vertebrates and ideally large mammals 
would also be highly beneficial.  The ideal candidate will also be able to work 
both independently and as part of a team.  A very high standard of spoken and 
written English is required and a proven track record of publishing in high 
quality international peer-reviewed journals would be advantageous.

The working environment:  The postdoc will join the Hoffman lab, a young and 
dynamic group comprising five PhD students and two postdocs.  They will be 
based at the Department of Animal Behaviour at Bielefeld University 
(www.uni-bielefeld.de/biologie/vhf/index.html).  The department is the oldest 
of its kind in Germany and currently hosts around six principal investigators, 
ten postdocs and twenty PhD students.  It offers a stimulating international 
environment and an excellent research infrastructure including brand new 
molecular laboratories.  The working language of the Department is English.  
The postdoc will also have the opportunity to interact closely with the 
cooperation partner (Dr Jaume Forcada) during two Antarctic field seasons and 
via placements at the British Antarctic Survey in Cambridge.

Bielefeld University is particularly committed to the career development of its 
employees.  It offers attractive internal and external training and further 
training programmes.  Employees have the opportunity to use a variety of 
health, counselling and prevention programmes.  Bielefeld University places 
great importance on a work�Cfamily balance for all its employees.  Bielefeld is 
a city of 325,000 inhabitants with an attractive historical centre and easy 
access to the Teutoberger Wald for hiking and other outdoor pursuits.  It 
offers a very high standard of living and is well connected to most major 
European cities.

The collaborative research centre: The postdoc will be embedded within a larger 
collaborative research centre (SFB) comprising 18 principle investigators, 8 
postdocs and 16 PhD students based at Bielefeld University, the University of 
Münster and the University of Jena.  The aim of the SFB is to produce a 
conceptual and empirical synthesis of individualisation across behaviour, 
ecology and evolution.  The SFB will provide exceptional opportunities for 
interdisciplinary collaboration and academic networking, together with 
structured training, scientific exchange and early career support programmes.  
Full details of the SFB can be found at www.uni-bielefeld.de/biologie/crc212.

Renumeration: Salary will be paid according to Remuneration level 13 of the 
Wage Agreement for Public Service in the Federal States (TV-L) and includes 
health insurance.

Application procedure: To apply, please provide: (i) a letter of motivation 
including a statement of your research interests and skills and experience 
relevant to the position; (ii) a CV including publication list; (iii) names and 
contact details of two referees willing to write confidential letters of 
recommendation; (iv) Please also state where you saw the position advertised.  
All materials should be e-mailed as a single PDF file to: 
[email protected] with 'Postdoc application' in the subject line. 
 The application deadline is January 7th 2018 and interviews will take place 
shortly thereafter.  After the decision, the position should start as soon as 
possible, although there is some scope for flexibility depending on the 
timeframe of the most qualified applicant.  For further information, please see 
www.thehoffmanlab.com and / or contact Joe Hoffman 
([email protected]) with any informal inquiries.
