Dr Robert Treloar

Robert Treloar is a senior research scientist within the Digital Research and Development Group at Unilever PLC a large consumer packaged goods company.

After joining Unilever in 1992, initially with a background in theoretical physics, he has spent the last 28 years applying computational methods to a wide range of business challenges. During that time he has benefited from and been challenged by multiple waves of technology innovation, from the emergence of data visualisation and VR and developments, through many incarnations of machine learning and AI with allied developments in sensor science and communications tech to the digitally connected world of today.

Over that time his interests have become very much focused on the intersection of these technologies with the consumer -  from using to understand behaviour and product use in life and building perceptually relevant models of human sensing through digital interaction to the opportunities for consumer facing product technologies.

Robert currently works with the business and external partners on a range of projects at the interface of AI, optimisation, personalisation and digital product technologies.  Some particular interests include learning from data /sensing in uncontrolled environments, hybrid products, exploiting prior knowledge in data poor environments and the explainable AI, trust and privacy agenda, and he leads Unilever’s interaction with the Horizon Digital Economy Institute and associated Doctoral Training Centre.
