Nowadays computation is considered to be one of the pillars of modern science. This is reflected in the fact that much scientific research and industry work relies heavily on technology and computation. As university educators we need to equip graduates with the tools to help them succeed in their discipline. The study reported here is part of a larger project which aims to identify computational practices used by faculty from across the College of Science in an R1 Irish university in their disciplines and research, in order to inform the design of a computational science course intended for first-year undergraduate students. This paper reports on findings from one-to-one interviews with fourteen faculty from across six schools in the college. Their understanding of the nature of computational thinking and their views on the role that computation does/can play in the undergraduate science curriculum, and specifically in teaching and learning within their disciplinary program are presented. Concerns and challenges related to the embedding of computation in undergraduate science programs voiced by participants are presented here. Finally, implications of the findings for the design of the first year computational science course are discussed
