Wishart is a successful serial entrepreneur. Since 1995 he has launched 8 successful start-up biotech companies, including Chenomx,[5] OMx Personal Health Analytics[6] and Molecular You Corp.[7] With more than 500 publications and >100,000 citations over his career,[8] he has been consistently ranked among the world's top 100 scientists in any discipline[9][10] and among the world's top 200 life scientists.[11]
Early life and education
Wishart was born and raised in Edmonton, Alberta, Canada and has one brother, Ian (a physician) and one sister, Sandy. His mother, Patricia worked as a naturalist and author; his father William was a wildlife biologist with the government of Alberta. Wishart identifies as Metis. He has both Cree and Assiniboine ancestry from his father's side and Scottish ancestry from his mother's side. As a youth, Wishart learned to hunt, fish and trap from his father, who also used to operate his own trapline. These early experiences with the natural world inspired Wishart's intense interest in natural science.[citation needed]
Wishart received his B.Sc. (Honours, First Class) in physics from the University of Alberta in 1983 and his M.Phil. (1986) and Ph.D. degrees (1991) in molecular biophysics from Yale University. Wishart completed his Ph.D. under the supervision of Frederic M. Richards and his post-doctoral studies (1991–1995) under the supervision of Brian D. Sykes.[12]
Academic career
Wishart started his academic career as an assistant professor in 1995 with the Faculty of Pharmacy and Pharmaceutical Sciences at the University of Alberta where he held the Bristol Myers Squibb Chair in Biotechnology for 10 years. He was promoted to associate professor in 2002 and full professor in 2003, joining the Departments of Computing Science and Biological Sciences in the Faculty of Science at the University of Alberta. Because of his growing involvement in clinical chemistry, Wishart was appointed as an adjunct professor in the Department of Laboratory Medicine and Pathology in 2012. In recognition of his outstanding contributions and scholarship in teaching, research and service to the University of Alberta, Wishart was appointed as a Distinguished University Professor in 2018.[13] From 2004-2016, Wishart also served as a senior research officer and the director of nanobiology at the National Research Council of Canada with the National Institute of Nanotechnology, located on the University of Alberta campus.
Research
Wishart's research interests span a number of diverse areas including structural biology, computational biology, bioinformatics, nanobiology, metabolomics, nuclear magnetic resonance (NMR) spectroscopy and mass spectrometry. A common theme to his research career has been the development of techniques, technology cores, protocols, data resources or computer programs that make science simpler, faster, cheaper or easier. This work has led to a number of important discoveries that have fundamentally transformed the fields of biomolecular NMR, metabolomics and computational biology.[1][2][3]
Biomolecular NMR
Wishart began his research career in the field of protein NMR in the early 1990s, focusing on using NMR spectroscopy to characterize protein structure and protein denaturation. At the time, protein structural analysis by NMR required hundreds of hours of manual data analysis and data tabulation. In an effort to accelerate the process, Wishart discovered an interesting trend with regard to how the NMR chemical shifts of amino acid residues changed systematically with regard to their secondary structure. He proceeded to develop a technique, called the chemical shift index, also known as CSI, that used a set of simple rules and simple chemical shift tables that allowed scientists to directly use protein chemical shift assignments to rapidly determine the type and location of protein secondary structures in proteins in just seconds.[14][15] Subsequently, Wishart showed how NMR chemical shifts could be used to easily and rapidly measure protein flexibility via the random coil index or RCI.[16][17] Later, he showed how it was possible to use chemical shifts to determine protein backbone torsion angles with a program called PREDITOR.[18] Wishart also determined how chemical shifts could be used to measure residue accessible surface area,[19] and to identify super secondary structure elements.[19][20] To further extend this work, Wishart developed innovative methods to determine the 3D structure of proteins using a technique called chemical shift threading with programs such as GeNMR, CS23D and E-Thrifty.[21][22][23] To help compare and assess existing protein NMR structures, Wishart also developed methods to accurately predict protein chemical shifts from 3D coordinates using programs such as ShiftX and ShiftX2.[24][25] At the same time he also developed methods to re-reference incorrectly assigned protein chemical shifts using programs such as SHIFTCOR and PANAV.[26] These programs were used to help create protein NMR databases such as RefDB that contain 1000s of re-referenced chemical shifts.[27] Wishart's papers describing these NMR methods have been cited more than 15,000 times and are now considered[by whom?] to be foundational techniques for much of modern protein NMR.
Metabolomics
In the early 2000s, Wishart turned his attention from looking at big molecules such as proteins to looking at small molecules (metabolites). In 2001 he developed and then patented NMR-based techniques (leading to the spin-off company Chenomx[5]) that permitted the rapid identification and quantification of metabolites by NMR in biofluids.[28] In 2005, he conceived of the Human Metabolome Project (HMP) [29] – the metabolomic equivalent of the Human Genome Project. Wishart succeeded in raising >$10 million in funding from Genome Canada and launched a multi-institutional, pan-Canadian program to systematically identify all metabolites, drugs and xenobiotics in clinically important human biofluids. The goal of HMP is to provide the scientific community with easily accessible reference data about human metabolites, thereby making metabolomic data analysis more comprehensive and much simpler. As of 2022[update], the HMP is still ongoing and has led to the identification of >240,000 human metabolites, >6000 drugs and drug metabolites, >70,000 food constituents and >3000 toxins and contaminants.[30][31][32] This information, along with many tools to facilitate metabolite identification and interpretation, have been archived in several publicly available databases created by the Wishart lab. These include the Human Metabolome Database (HMDB), which contains data on human metabolites and their structures, along with descriptions, NMR spectra and MS spectra.[33] Another resource developed from the project is DrugBank,[31] a database of all known, approved drugs and their target molecules. Other databases developed by the Wishart lab include FooDB,[32] a database of food constituents and food additives; and T3DB,[34] a database of toxic compounds and contaminants as well as their toxicological effects. The metabolomic database resources from the HMP are widely used, with >60 million page view/year and the papers associated with the HMP have been cited >30,000 times over the past 10 years.[citation needed]
In 2011, Wishart founded The Metabolomics Innovation Centre (TMIC) and served as its first director (2011-2019). TMIC is widely known as Canada's national metabolomics laboratory. Wishart's laboratory within TMIC houses >$8 million in modern LC-MS, GC-MS and NMR equipment. His lab routinely processes >20,000 samples each year. Using this wide array of equipment, Wishart helped develop a number of quantitative metabolomics techniques for NMR [35][36] and liquid chromatography mass spectrometry.[37][38] Using these methods, Wishart and his team have conducted comprehensive, quantitative metabolome analyses of human serum,[39] urine,[40] saliva,[41] cerebrospinal fluid [42] and feces.[43]
Computational biology and open science
Wishart is noted[by whom?] for having made all his lab's data resources, computer programs, algorithms and techniques publicly accessible. This open science/open access initiative has been aimed at providing tools and techniques to make biomolecular NMR, metabolomics, structural biology and a number of related techniques more accessible for all scientists. So far, this initiative has led Wishart's lab to develop and release more than 100 publicly accessible web servers and web-based databases,[44] including NP-MRD[45] and CFM-ID.[46] To further his open-science efforts, Wishart co-founded several educational bioinformatics programs such as the Canadian Bioinformatics Workshops and has been actively involved in other international standardization and open-source initiatives to make computational biology resources more widely available and accessible.
Personal life
Wishart is married to Debby Waldman, a freelance writer and editor from Utica, New York. He has two children: Elizabeth, an epidemiologist; and Noah, a civil engineer. They all live and work in Edmonton, Alberta.[citation needed]
