Career Highlights

  • Evaluating the impacts of catastrophic fresh-water flood events on genetic differentiation, diversity and population structures of Californian and Seattle tunicate populations throughout a period of 12 years and seven sampling sessions.
  • Employing DNA barcoding as a biodiversity and conservation applied tool for identifying fish fauna from the south-eastern Mediterranean also with an eye to establish the foundation for follow-up studies that will use environmental DNA (eDNA) tracks of native and invasive species, and for the application of eDNA concepts and methodologies in nature conservation.
  • Distinguish two anchovy species (Engraulis spp.) from the Mersin Bay using geometric morphometrics, fourier analysis of otolith shape, and nuclear-DNA markers.
