Research

  • Examination of the relation between husbandry procedures to animal welfare and experimental outcomes with particular emphasis on refinement. More info
  • RepFail: Understanding Replication Failure in Animal Research – Lack of Scientific Rigor, Low Statistical Power, or Standardization? RepFail
  • European Quality in Preclinical Data (EQIPD)
Dr. Janja Novak's first degree was in Biology at the University of Ljubljana (Slovenia) followed by the MSc in “Applied Animal Behaviour and Animal Welfare” at the University of Edinburgh (UK), where her dissertation was on social structure of a larger group of dogs housed in a rescue shelter (in association with Bristol University). After completing the MSc course she worked for several animal protection charities in different fields, ranging from animals in captivity to farm animals, before starting PhD studies in 2011.
Her PhD project involved looking at affective states in laboratory mice, developmental aspects of stereotypic behaviour, and mechanisms underlying these abnormal behaviours and she graduated in 2016 from the University of Bern.
