Isla applies her meteorological knowledge to real world challenges, including energy. Staying in academia to complete a postdoc provided a robust understanding of weather forecasting. Moving to ILEX energy consulting enabled an appreciation of how the supply/demand balance drives energy markets. Missing weather, she became the meteorologist for an energy trading team in the City in 2004, went on to trade weather-based energy strategies for a hedge fund, then founded Lake Street Consulting Ltd in 2014, whose aim is to help more organisations use weather data to improve their business. Isla is a Fellow of the Royal Meteorological Society.
