Dr Lester Simmonds


Lester has a PhD in environmental physics, working for over 25 years in academic research measuring and modelling water and solute dynamics in environmental systems. This involved work with space agencies to develop ways of using satellite remote sensing to provide global maps of soil moisture. In 2004 Lester and two colleagues formed a company, Pool Sentry, to put some of this science into practice, helping pool operators run their pools better. Pool Sentry is now an industry leader in developing quantitative understanding of how pools function, which is the basis of the services they provide using very practical tools for customers to improve pool management.
