Rachel Halpin completed her PhD in 2009, in University College Dublin. Her postgraduate studies were a collaborative effort between the Department of Industrial Microbiology and the Department of Food Science in UCD, under the supervision of Professor Dolores O’Riordan, Michael O’Sullivan and Dr Damien Brady. She then worked briefly as a research fellow in Safefood, Co. Cork. Following this, Rachel returned to UCD to undertake a post-doctoral role in the SMARTMILK project; a two year R&D project funded by the Seventh Framework Programme of the EC under the “Research for SMEs” sub-programme. This work conducted under principal investigators Dr Francesco Noci, Dr Paul Whyte and Professor James Lyng.  Following this, for a two-year period, Rachel was employed as a project co-ordinator for an Enterprise Ireland (EI) funded industrial lead research project (ILRP). This project focused on the development of technologies to improve bioavailability of animal feed, where Rachel was responsible for co-ordinating the day-to-day activities of the UCD research team (which consisted of seven principal investigators, five researchers and an intellectual property advisor), and for liaising with the industrial stakeholders and EI. Subsequently, Rachel spent over two years working in the R&D department of Kerry Ingredients and Flavours. During this time, she worked in the Proteins team, part of Kerry’s Functional Ingredients and Actives (FI&A) division. She was based both in the Listowel production facility in Co. Kerry, and also in Kerry’s Global Technology and Innovation Centre in Naas, Co. Kildare. A faculty member in Dublin Institute of Technology since March 2017, she is currently appointed as assistant lecturer in the School of Food Science & Environmental Health in DIT.
