Dr Sarah Diermeier
Chief Scientific Officer & Founder

Dr Sarah Diermeier is Chief Scientific Officer and Founder of Amaroq Therapeutics, responsible for leading the research that Amaroq’s technology is based on. She is also a Principal Investigator   in the Department of Biochemistry at the University of Otago, with an interest in identifying novel therapeutic targets for cancer, and a Rutherford Discovery Fellow of the Royal Society Te Apārangi.

Dr Diermeier has extensive experience in the study of lncRNAs in cancer, having undertaken post-doctoral studies under Prof David Spector of Cold Spring Harbor Laboratory (NY, USA), an expert in lncRNA research. As part of this, she established computational and experimental pipelines to identify and characterise lncRNA drivers in breast cancer. She has collaborated with Ionis Pharmaceuticals to develop lncRNA-targeting ASOs and studied these new drugs in vitro in primary cells and organoids and in vivo in mouse models. Her previous work lead to the identification of >30 clinically actionable lncRNAs in breast cancer and several high impact publications (including in Cell Reports, Genes and Development, and Nature Communications).


Dr Diermeier received her PhD in chromatin dynamics and genomics in 2013 from the University of Regensburg, Germany. From 2013-2018 she conducted research at Cold Spring Harbor Laboratory, NY, USA. In 2016, she was awarded a Susan G. Komen postdoctoral fellowship, and in 2017, a K99/R00 Pathway to Independence Award by the United States National Cancer Institute (NCI/NIH). Dr Diermeier rescinded this prestigious award in 2018 to move to New Zealand, where she started her own independent research group at the University of Otago. The overarching questions of her research are to identify novel therapeutic targets in cancer and to elucidate the genetic and epigenetic mechanisms of cancer gene regulation. Due to her outstanding success in research, Dr Diermeier recently received an Early Career Award for Distinction in Research from the University of Otago.
