Dr Peter Georgeson
I am a postdoctoral cancer researcher based at The University of Melbourne in Associate Professor Dan Buchanan's Colorectal Oncogenomics Group.
I have an ongoing interest in cancer genomics, statistical methods, and machine learning. My current research focuses on the application of tumour mutational signatures to understanding and detecting the underlying aetiology driving different sub-types of colorectal cancer.
Research Interests: mutational signatures, colorectal cancer, statistical learning, genomics, bioinformatics.
