Andrew Lumsden is a neurobiologist whose research focuses on how cellular and molecular identities are established during development of the vertebrate brain. In particular, his influential experiments demonstrated that the hindbrain has a segmented organisation. More recently, Andrew has concentrated his work on the developing forebrain.

His research interests include characterising the development of complex structures in the early forebrain and midbrain, and the role of the Hox genes in hindbrain and branchial arch development. He also studies the emergence of respiratory rhythm generators in another part of the brain known as the medulla. To assist his research, Andrew developed the Lumsden BioScissors, an instrument used for fine tissue dissection that is now commercially available.

Andrew has received a number of honours and awards for his work, including the W. Maxwell Cowan Prize in 2007 for his outstanding contributions to developmental neuroscience. He has published numerous scientific papers, and is co-author of the book The Developing Brain (2001).
