Greg Tyrelle
Bioinformatics Territory Specialist

Commercially oriented bioinformatician with a wide range of experience in genomics data analysis. Ranging from small bacterial de novo genome assembly, to full scale whole human genome analysis and interpretation. Working closely with sales, I have a deep understand of how NGS technologies are being employed in markets such as academia, pathology/oncology, pharma, clinical and agribio. I specialize in taking complex bioinformatics analysis workflows, methods and statistical approaches and distilling these to their core concepts to communicate with customers.
