We are pleased to announce the 5th MSA ECR Symposium to be held at Macquarie University, Sydney, 5 - 6 February 2018. Following the success of the 4th MSA ECR Symposium in Geelong 2014, we hope to bring you another exciting event in Sydney 2018. The MSA ECR Symposium provides a wonderful forum for young membrane scientists and engineers, not only from Oceania, but also around the world, to share their latest innovative work on membrane science and technology. The symposium will bring you excellent experience through 4-min presentation, career development, proposal writing workshops, and outstanding mentoring from seniors. On behalf of the organising committee, we look forward to welcoming you to the 5th MSA ECR Symposium, and seeing you in beautiful Sydney!
