Speaker Bio

Until the United States and Israel launched their attacks on Iran on February 28, most of us hadn’t given the Strait of Hormuz much thought. That has changed dramatically. The effective closure of the Strait has resulted in the largest disruption in global energy supply since the 1970s and is having major impacts on the global economy.

Greg Walker enjoyed a career in energy that spanned the globe. He worked in Australia, Angola, Bolivia, Brazil, Colombia, Egypt, Indonesia, Iraq, Malaysia, Norway, Papua New Guinea, Russia, Spain, Trinidad, the UK, and Vietnam. His PhD research at Cambridge University focused on fluid dynamics in fractures, as applied to the movement of magma. He also worked briefly in nuclear power, exploring long-term storage with UK Nirex and fusion research with the UKAEA at Culham. Most recently, he worked in Spain for Repsol, managing a team across five countries and continuing research on machine learning for data integration, which he began in 2003. Greg is now retired.

Greg will speak about the disruptions and impacts on global trade caused by the war with Iran.
