Personal profile


Dr Alfred Chin Yen Tay completed his PhD degree from UNSW (2010) and since then have been working as a research associate and a laboratory manager in the Helicobacter Research Laboratory in UWA, Marshall Centre for Infectious Diseases Research and training. Dr Tay has great interest in antibiotic resistance and the genetic makeup of H. pylori. While working closely together with Prof Barry Marshall, Nobel Laureate of 2005, he has been monitoring antibiotic resistance patterns among the Western Australian population. Dr Tay was also given the opportunity to sequence and analyse the genome of these antibiotic resistance strains to understand their genomic structure and their pathogenicity.  In addition, with the Next Generation Sequencing analytical skill, Dr Tay is leading his team to identify alternative genomic markers to redefine Helicobacter as a species and understand how Helicobacter evolved into human pathogen. In community contribution, Dr Tay is the current webmaster of www.helicobacter.com and www.helico.com. Other than maintaining and upgrading the websites, Dr Tay answered questions in the forum in a daily basis and provide all kinds of information about H. pylori to anyone in the world.
