David A. Fell is a British biochemist and professor of systems biology at
Oxford Brookes University Oxford Brookes University (formerly known as Oxford Polytechnic (United Kingdom), Polytechnic) is a public university, public university in Oxford, England. It is a new university, having received university status through the Further and High ...
. He has published over 200 publications, including a textbook on ''Understanding the control of metabolism'' in 1996.


Early work

Fell did research on the physical biochemistry of yeast
pyruvate kinase Pyruvate kinase is the enzyme involved in the last step of glycolysis. It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to adenosine diphosphate (ADP), yielding one molecule of pyruvate and one molecule of ATP. Pyru ...
. He obtained a position at Oxford Polytechnic as a lecturer. His early work at Oxford Polytechnic focussed on haemoglobin where he developed more precise techniques for monitoring oxygen saturation and the breakdown of
2,3-bisphosphoglycerate 2,3-Bisphosphoglyceric acid (conjugate base 2,3-bisphosphoglycerate) (2,3-BPG), also known as 2,3-diphosphoglyceric acid (conjugate base 2,3-diphosphoglycerate) (2,3-DPG), is a three-carbon isomer of the glycolytic intermediate 1,3-bisphosphoglyc ...
by Fe(III)-haemoglobin. At this time he also worked on the first modelling studies related to the functioning of high- and low-''K''m cyclic nucleotide phosphodiesterases on the regulation of adenosine 3',5'-cyclic monophosphate (cAMP)


Later career

From the early 1980s David Fell switched his research to

. Given that his early work had a significant mathematical and computational component, he was ideally positioned to consider a more quantitative approach to studying the properties of cellular networks. It was against this background that he turned to the relatively new field called
metabolic control analysis Metabolic control analysis (MCA) is a mathematical framework for describing metabolic, signaling, and genetic pathways. MCA quantifies how variables,elastsuch as fluxes and species concentrations, depend on network parameters. In particular, it is a ...
as a means to understand the principles of metabolic regulation. Before the development of metabolic control analysis, understanding metabolism was based on qualitative arguments which resulted in some incorrect conclusions (rate-limiting steps). Much of Fell's research for the next 20 years focussed on extending and applying metabolic control analysis to metabolism. This work culminated in the publication of his textbook, ''Understanding the control of metabolism''. In 1986 he published with his graduate student Rankin Small, one of the earliest flux-balance models where they used linear programming to examine the efficiency in the conversion of glucose into fat. He was also one of the first researchers to use the Gillespie method for stochastic simulation in cellular biology, a method that is now routinely used in systems biology. In the late 1990s his research started shifting more towards stoichiometric analysis with particular emphasis on elementary modes and the analysis of larger networks such as those involved in photosynthesis and whole genome scale models in a variety of organisms including one of the first genome scale models of ''Arabidopsis''.


Publications

Other than his textbook, which has been cited 1464 times (Sept, 2018), his top ten publications include: two publications related to the evolutionary age of metabolism using small-world analysis, the definition of a pathway in terms of elementary modes, three reviews on metabolic control analysis including a republication of the seminal work, ''Control of Flux'' by Kacser and Burns, two research papers on
