Research
Sarah's PhD research focused on the role of novel plant-based foods (plant-based foods that try to mimic and replace animal products) to transitioning towards more nutritious, affordable, and sustainable diets in the UK. I'm passionate about exploring the connections between climate change and food systems, especially understanding how we can drive behavior change toward more plant-forward diets.
