I think it is a great idea of Professor Barry Logan to bring in external speakers to enrich his classes and give the students a wider perspective of Plant sciences. I first met Barry 21 years ago when he was a grad student and I was doing a post doc at RSBS at the ANU in Canberra. His PhD supervisors were on sabatical and brought two grad students with them. It is a small world because Todd Rosenstiel (Portland State) who we worked with in Antarctica last year also worked in the same lab as Barry. I hope the students enjoyed the class and maybe some of them will be inspired to work with plants or in Antarctica in future.
