  • Conducted genetic analysis of over 3000 samples with minimal to no supervision.
  • Extracted DNA from tissue samples (extraction kits, phenol-chloroform, high-salt protocols)
  • Amplified nuclear and mitochondrial DNA via PCR (optimization, troubleshooting)
  • Performed (Sanger) cycle sequencing reactions, edited and analyzed sequence data (Sequencher, PAUP, MacClade, GeneScan).
