Dr. Marcus D. Hanwell is a Technical Leader at Kitware, where he leads the Open Chemistry project and play a critical role in developing new workflows in Git, performing Gerrit code review, and contributing to next generation build systems in the VTK, ITK, and Titan projects. Dr. Hanwell is the Principal Investigator on the Open Chemistry project, which focuses on developing open-source tools to for chemistry, bioinformatics, and materials science research. He was inspired to pursue the development of computational chemistry tools while working on his experimental/computational Physics PhD and postdoctoral studies, when he realized how outdated and cumbersome current tools are for handing the scale of data required by chemists. In his spare time, Dr. Hanwell is an active member of the KDE open-source communities, and of the KDE e.V. He is one of the core developers of Avogadro, an open-source, 3D, cross-platform molecular visualization and editing application/library; this work was featured by Trolltech as an instance of “Qt in Use.” Dr. Hanwell has also won a Blue Obelisk award for his work in Open Chemistry, and continues to develop and promote open approaches in chemistry and related scientific fields.
