Bradford Barham

I am a Professor in the Department of Agricultural and Applied Economics at the University of Wisconsin-Madison, where I have been on the faculty since 1987. I am an honorary professor at NUI Galway. I have had the pleasure of visiting Ireland on multiple occasions and spent a sabbatical there in 2019-20, which was truncated by the Covid pandemic. My research and teaching focus on two main themes: 1. Identifying and addressing the drivers of inequality and poverty in Latin America, especially in rural areas, and 2. Examining policies, technologies, and farmer management decisions shaping agricultural sustainability outcomes in the US, Ireland, and Latin America. To better understand individual economic decisions, I use field work, such as surveys, interviews, and well-framed experiments as empirical evidence to test economic models and ideas. For more details about my research, click here or email

Paula Byrne

Dr. Paula Byrne is a Postdoctoral Researcher with Evidence Synthesis Ireland & HRB-Trials Methodology Research Network at NUI Galway. Her work focuses on evidence synthesis, scientific uncertainty, and how health ‘facts’ and ‘misinformation’ are defined and dealt with. Previously, Paula worked with the Health Technology Assessment Directorate within HIQA. Here she developed a new method of justifying new practices in medical exposure to ionising radiation, which is currently being finalised. Also, she produced rapid reviews on a wide range of scientific topics to inform the National Public Health Emergency Team during the Covid-19 pandemic. Her PhD focused on the use of statins for primary prevention of cardiovascular disease and was supervised by Dr. John Cullinan. In particular, she considered the process of medicalisation and how ‘low-value’ medical care might be delineated or defined in the context of absolute risk reduction or number-needed-to-treat. For more details about Paula's research, email
