In this month’s newsletter, we would like to introduce PhD graduate, Claire Mercer from College of Science and Engineering.
Claire’s recently submitted thesis, “DNA Transfer Between Exhibits, Evidence Bags and Workspaces” received outstanding results from the examiners.
We asked Claire to share what led her to a PhD, the hardest part of the journey and advice to new students.
What was your research about in 1-2 sentences?
My research examined how DNA can accumulate on and transfer via forensic exhibit packaging, exploring the movement of DNA between exhibits and within workspaces in operational forensic laboratories.
What led you to undertake a PhD?
I was inspired to undertake a PhD because I really enjoyed my Honours research and wanted to continue exploring the topic further. It’s an important and understudied area, and I was motivated by the opportunity to contribute new insights that could make a meaningful difference in the field of forensic science.
What have you been doing since you completed?
Since completing my PhD, I have been working at the New Zealand Institute for Public Health and Forensic Science (formerly ESR) in Auckland, where I assist forensic laboratories around the world with the validation of DNA software.
What advice would you give to those who are about to undertake a PhD?
My advice would be to choose a topic you’re genuinely passionate about, because motivation is key throughout a PhD. Be prepared for challenges, stay organised, and make the most of the support and expertise around you.
A PhD is as much about developing resilience and problem-solving skills as it is about the research itself, so stay curious and don’t be afraid to ask for help when you need it.
What was been one of the hardest parts of the journey?
One of the hardest parts of the journey was managing the uncertainty that comes with research. Experiments don’t always go as planned and progress can feel slow at times, so learning to stay patient and adapt was a big part of the process.
