About me

My research life is about improving how we choose to use antibiotics across the globe. Antibiotics are remarkable drugs, and have added an average of over 20 years to our lives. Our modern world is founded on access to effective antibiotics, which is essential both for human and animal health.

Yet the world is full of paradox today: we knowingly overuse antibiotics in many settings, whereas in others we struggle to provide access to these most basic of medicines. All the while, we are collectively failing to invest in the development of new antibiotics and alternative therapies, as well as efforts that aim to preserve the value of our existing antibiotics.

My research has two main focuses:

1) Using a One Health approach and systems science methods to understand and improve antibiotic use and resistance in rural China

2) Understanding and improving undergraduate education of healthcare professionals on responsible antibiotic use across Europe
