Dr. Muireann Egan

Communications Officer, Teagasc Food Research Programme

Research Interests

My role is to promote the activities of the Teagasc Food Research Programme to various target audiences, including scientists, the food industry, other public agencies, research organisations, journalists, suppliers and the community. I coordinate food programme related conferences, webinars, open days and industry focused events (including training programmes and related initiatives). I also manage the social media accounts for the Teagasc Food Research Programme.
