# Paul Laursen > Paul Laursen, PhD, is an exercise physiologist, endurance coach and IRONMAN athlete. He is co-founder and Chief Scientist of Athletica, an AI coaching platform for endurance athletes; co-founder and CEO of HIIT Science; and Adjunct Professor of Exercise Physiology at Auckland University of Technology (AUT). He has published more than 150 peer-reviewed papers, with over 25,700 Google Scholar citations, on high-intensity interval training (HIIT), heart rate variability (HRV), pacing, fatigue, heat and AI in coaching. Paul co-edited Science and Application of High-Intensity Interval Training with Martin Buchheit (Human Kinetics) and wrote Athlete Intelligence: How to Turn Data Into Decisions (80/20 Publishing, early 2027). With Martin Buchheit he proposed Sports Science 3.0: AI and technology built on foundational sport science knowledge, which is the design basis of Athletica. He speaks to coaches, sport scientists, performance staff and athletes on Sports Science 3.0, HIIT, HRV, heat and endurance nutrition. ## Key pages - [About](https://www.paullaursen.com/about): Biography, roles and affiliations. - [Research](https://www.paullaursen.com/research): Research themes and selected peer-reviewed papers on HIIT, HRV, pacing, fatigue, heat and AI coaching. - [Books](https://www.paullaursen.com/books): Science and Application of High-Intensity Interval Training, and Athlete Intelligence. - [Keynote speaking](https://www.paullaursen.com/keynotespeaker): Keynote topics, upcoming and recent talks, booking enquiries. - [Coaching](https://www.paullaursen.com/coaching): Coaching for endurance athletes. - [Contact](https://www.paullaursen.com/contact): Speaking, media, research and coaching enquiries. ## Sports Science 3.0 and Athletica - [Sports Science 3.0: integrating technology and AI with foundational knowledge](https://sportperfsci.com/sports-science-3-0-integrating-technology-and-ai-with-foundational-knowledge/): Buchheit and Laursen, Sport Performance & Science Reports (SPSR 231). - [Athletica Methodology Hub](https://athletica.ai/methodology): The training science behind Athletica. - [Athletica](https://athletica.ai): AI coaching for runners, cyclists, triathletes, rowers and Hyrox athletes. - [HIIT Science](https://hiitscience.com): HIIT education and the Training Science Podcast. ## Profiles - [Google Scholar](https://scholar.google.com/citations?user=dbv3cxgAAAAJ) - [ORCID](https://orcid.org/0000-0003-1532-2697) - [Athletica author page](https://athletica.ai/author/paul-laursen) - [Substack](https://coachingprofessor.substack.com) - [LinkedIn](https://www.linkedin.com/in/paul-laursen-3ba25213)
