Opis

This innovative book provides a completely fresh exploration of bioinformatics, investigating its complex interrelationship with biology and computer science. It approaches bioinformatics from a unique perspective, highlighting interdisciplinary gaps that often trap the unwary. The book considers how the need for biological databases drove the evolution of bioinformatics; it reviews bioinformatics basics (including database formats, data-types and current analysis methods), and examines key topics in computer science (including data-structures, identifiers and algorithms), reflecting on their use and abuse in bioinformatics. Bringing these disciplines together, this book is an essential read for those who wish to better understand the challenges for bioinformatics at the interface of biology and computer science, and how to bridge the gaps. It will be an invaluable resource for advanced undergraduate and postgraduate students, and for lecturers, researchers and professionals with an interest in this fascinating, fast-moving discipline and the knotty problems that surround it.

O autorze

David Thoren wurde 1972 in Australien geboren. Offiziell arbeitet er als Grafikdesigner. Am liebsten treibt er jedoch seine Kollegen und Nachbarn mit absurden E-Mails zur Weißglut. 2008 ging sein Versuch, die ausstehende Rechnung seines Chiropraktikers mit einer selbst gezeichneten Spinne zu bezahlen, um die Welt. Seitdem gilt er als der berühmteste notorische Unruhestifter des Internets. Er lebt und provoziert in Adelaide.
