Barbara Ruth Holland is a New Zealand born Australian scientist. She is a Professor of mathematics and member of the Theoretical Phylogenetics Group at the School of Mathematics & Physics at the University of Tasmania. She has made substantial contributions to the methods for reconstructing phylogenetic trees from DNA and protein sequence data. Holland has published over 50 journal articles, presented over 30 invited or keynote lectures, refereed five conference proceedings, 2 book chapters and 1 book review. She is a senior editor of the scientific journal Molecular Biology and Evolution. Research Holland has research interests in phylogenetics, mathematical biology, population genetics, and epidemiology. Her primary area of interest is in the estimation of evolutionary trees, and she works to develop tools that can assess how well a given model describes a sequence of data. Holland uses her knowledge to help biologists translate the unsolved problems of their field into mathematical language. Career Holland is currently a professor of mathematics at the University of Tasmania in Australia, where she teaches statistics, operations research, and phylogenetics and is a member of the university's Theoretical Phylogenetics Group. Holland spent about a year beginning in 2001 as a Post Doctoral Researcher at Ruhr University Bochum in Germany. From 2002 to 2010 Holland was working in a number of different capacities at Massey University in New Zealand. For the duration of her stay she was a part of the Allan Wilson Centre as a Post Doctoral Fellow (2002-2005) and then as a Research Fellow (2005-2010). Holland spent a year as a lecturer in mathematics for the university beginning in 2007 and was a senior lecturer from 2008 to 2010, also in mathematics. In 2010 Holland began lecturing in mathematics at the University of Tasmania in Australia. From 2011 to 2014 she was Future Fellow at the university, a fellowship awarded to her by the Australian Research Council. Scientific meeting organizer From 2010 to 2014, Holland served as a co-organizer of Phylomania, a conference which sought to bring together phylogenetic researchers interested in theory to address some of the primary challenges in the field and further develop the branch of mathematics focused on computational phylogenetic methods. In 2010, she was also chief organizer of the New Zealand Phylogenetics Meeting in Whakapapa Village, February 9–14. Professional recognition Holland's expertise has allowed her serve as associate, principal, and co-investigator on a variety of research projects and has
