Paul A. Haynes is a Professor in the School of Natural Sciences at Macquarie University, who specialises in plant and environmental proteomics. His research laboratory has also branched out in recent years to include an active program in bioarchaeological proteomics in collaboration with colleagues in the Department of Ancient History. His research is mainly funded by the Australian Research Council, including a current Discovery Project, a current Training Centre in Bioactives, and a previous ARC Training Centre for Molecular Technologies in the Food Industry, where he was the Centre Director. He also is part of a current project with Sasha Tetu funded by National Parks and Wildlife, looking at proteome level changes in Alpine vegetation species due to anthropogenic impacts, and a current ARC funded project with Simon Griffith looking at changes in the proteome of sparrows due to environmental exposure to high lead levels. According to his Scopus profile, he has more than 184 publications which have been cited over 8400 times, for a H-index of 49.

Professor Haynes is the Director of Higher Degree Research for the School of Natural Sciences, with overall responsibility for the continued successful progression of around 300 Higher Degree Research students present in the school at any given time. He is a tireless advocate for higher degree research students, and his excellence in this area was recognised in 2017 when he received the Macquarie University award for Excellence in Higher Degree Research Student Supervision.

He is currently President of the Asia Oceania Agricultural Proteomics Organisation, and in that role is responsible for organising an annual meeting which typically has about 200 to 300 attendees from all over Asia. He was a member of the ARC College of Experts from 2019 to 2021, which required playing a major role in grant assessments and policy development. He is also a member of the Executive Editorial Board of Proteomics, and the editorial boards for Frontiers in Plant Proteomics and International Journal of Molecular Sciences.

Professor Haynes teaches a postgraduate coursework unit in MOLS8212 Proteomics Technologies and Applications in second semester, and co-teaches a third-year undergraduate unit in BMOL3402 Molecular Biology and Genomics in first semester. He also lectures in several other units and is the convener and chief organiser for MOLS8902 research experience.

Paul A. Haynes graduated from Macquarie University with a Ph.D. in chemistry in 1994. After postdoctoral Fellowship positions at the Rockefeller University in New York and the University of Washington in Seattle, he was a principal scientist at the Torrey Mesa Research Institute in San Diego, before taking up a position as an Associate Professor at the University of Arizona in Tucson. He returned to Australia in 2006 to take up a NSW government funded fellowship position at Macquarie, and was appointed in 2011 as a Professor in the Department of Molecular Sciences, which was incorporated into the School of Natural Sciences in 2022.
