'''Denis Noble''' [[Fellow of the Royal Society|FRS]] (born [[November 16]][[1936]]) is an eminent [[United Kingdom|British]] [[biologist]] who held the Burdon Sanderson Chair of Cardiovascular Physiology at [[University of Oxford|Oxford University]] from 1984-2004 and is now Professor Emeritus and co-Director of Computational Physiology. He is one of the pioneers of [[Systems biology|Systems Biology]] and developed the first viable mathematical model of the working [[heart]] in 1960<ref name="homepage">[http://noble.physiol.ox.ac.uk/People/DNoble/ Biography], Denis Noble homepage.</ref>. His research focuses on using [[Computer simulation|computer models]] of [[Organ (anatomy)|biological organs]] and organ systems to interpret function from the molecular level to the whole organism. Together with international collaborators, his team has used supercomputers to create the first virtual organ, the virtual heart.
Noble was educated at [[Emanuel School]] and [[University College London]] (UCL)<ref name="homepage"/>. In 1958 he began his investigations into the mechanisms of heartbeat. This led to two seminal papers in ''[[Nature (journal)|Nature]]'' in 1960 giving the first proper simulation of the heart. From this work it became clear that there was not a single oscillator which controlled heartbeat, but rather this was an [[Emergence#Emergent properties|emergent property]] of the feedback loops in the various channels. In 1961 he obtained his PhD working under Otto Hutter at UCL<ref>Dennis Noble (2006). ''The Music of Life'', ISBN 0-19-929573-5</ref>.
As Secretary-General of the International Union of Physiological Sciences 1993-2001, he played a major role in launching the [[Physiome]] Project, an international project to use computer simulations to create the quantitative physiological models necessary to interpret the [[genome]].
==Awards and recognition==
His major invited lectures include the Darwin Lecture for the [[British Association]] in 1966, the Nahum Lecture at [[Yale]] in 1977 and the Ueda lecture at [[Tokyo University]] in 1985 and 1990 along with his victory in 1991. He was President of the Medical Section of the [[British Association]] 1991-92. He was elected an Honorary Member of the [[Royal College of Physicians]] in 1988 and an Honorary Fellow in 1994, an Honorary Member of the [[American Physiological Society]] in 1996 and of the [[Japanese Physiological Society]] in 1998. In 1979 he was awarded a [[Order of the British Empire|CBE]], and elected a Fellow of the [[Royal Society]]. In 2008 he received an Honorary doctorate of science from the [[University of Warwick]]
==Views on reductionism==
His 2006 book ''The Music of Life'' examines some of the basic aspects of systems biology, and is critical of the ideas of [[genetic determinism]] and genetic [[scientific reductionism|reductionism]]. He points out that there are many examples of [[feedback loop]]s and "downward [[Causality|causation]]" in biology, and that it is not reasonable to privilege one level of understanding over all others. He also explains that [[gene]]s in fact work in groups and systems, so that the genome is more like a set of organ pipes than a "blueprint for life".
He contrasts Dawkins's famous statement in ''The Selfish Gene'' ("Now they [genes] swarm ... safe inside gigantic lumbering robots ... they created us, body and mind; and their preservation is the ultimate rationale for our existence") with his own view: "Now they [genes] are trapped in huge colonies, locked inside highly intelligent beings, moulded by the outside world, communicating with it by complex processes, through which, blindly, as if by magic, function emerges. They are in you and me; we are the system that allows their code to be read; and their preservation is totally dependent on the joy we experience in reproducing ourselves. We are the ultimate rationale for their existence". He further suggests that there is no empirical difference between these statements, and claims that they differ in "metaphor" and "sociological or polemical viewpoint"<ref>''The Music of Life'', pp. 12-14</ref>.
==Principles of Systems Biology==
Noble offers 10 Principles of Systems Biology<ref>Noble,D. Claude Bernard, the first systems biologist,and the future of physiology ''Experimental Physiology'' (2008)Published online 19th October 2007 expphysiol.2007.038695v1</ref>:
# Biological functionality is multi-level
# Transmission of information is not one way.
# DNA is not the sole transmitter of inheritance.
# The theory of biological relativity: there is no privileged level of causality
# Gene ontology will fail without higher-level insight
# There is no genetic program
# There are no programs at any other level
# There are no programs in the brain
# The self is not an object
# There are many more to be discovered; a genuine ‘theory of biology’ does not yet exist
