Judy Hirst is a British scientist specialising in mitochondrial biology. She is Director[2] of the MRC Mitochondrial Biology Unit at the University of Cambridge.

Early life and education

[edit]

Hirst grew up in Lepton, a village near Huddersfield, West Yorkshire, and attended King James's School and Greenhead College, Huddersfield.[3] She studied for an M.A. in chemistry at St John's College, Oxford,[2] and then was awarded a Doctor of Philosophy degree at Lincoln College, Oxford, in 1997, for research supervised by Fraser Armstrong on electron transport in redox enzymes.[1]

Career and research

[edit]

Following her D.Phil., Hirst held a fellowship at the Scripps Research Institute in California, before moving to Cambridge.[4]

As of 2023 Hirst is a professorial fellow and Director of Studies in Natural Sciences Chemistry at Corpus Christi College, Cambridge,[4] and since 2020 has been director of the MRC Mitochondrial Biology Unit having previously been its assistant director (2011-2014) and deputy director (2014-2020). Her main research interest is mitochondrial complex I.[2]

Hirst has been published in 2018 on Open questions: respiratory chain supercomplexes – why are they there and what do they do?[5] and working with Justin Fedor, published research on mitochondrial supercomplexes in Cell Metabolism.[6] Recent research in her team includes a study, published in May 2020 by the American Chemical Society Synthetic Biology on 'Adenosine triphosphate (ATP), the cellular energy currency, is essential for life. The ability to provide a constant supply of ATP is therefore crucial for the construction of artificial cells in synthetic biology' which has developed a 'minimal system for cellular respiration and energy regeneration'.[7]

Awards and honours

[edit]

Early in her career, Hirst was awarded EMBO Young Investigator Award (2001) and Young Investigator Award from the Royal Society of Chemistry Inorganic Biochemistry Discussion Group (2006).[8]

Hirst was elected a Fellow of the Royal Society (FRS) in 2018.[9] She was awarded an Interdisciplinary Prize of the Royal Society of Chemistry in the same year.[10] In 2019, Hirst was elected Fellow of the Academy of Medical Sciences[11] with the citation:

Judy Hirst, Professor of Biological Chemistry at the MRC Mitochondrial Biology Unit, Cambridge, has had a definitive hand in every advance towards defining the highly complex mechanism of complex I catalysis, and has developed new physical and biochemical methods to address the elusive coupling mechanism between the redox reaction and proton translocation. She established the mechanism of complex I inhibition by the anti-diabetic drug metformin, and has used kinetic and thermodynamic strategies to define how superoxide production by complex I, responds to the intramitochondrial NADH/NAD+ ratio to directly link two pathological effects of complex I dysfunction. This seminal work has brought understanding that is fundamental to critical issues of health and disease on a global stage.[12]

Hirst was awarded Keilin Memorial Lecture and Medal in 2020 for research which:

has made pivotal contributions to understanding energy conversion in complex redox enzymes: how they capture the energy released by a redox reaction to power proton translocation across a membrane, or catalyse the interconversion of chemical bond energy and electrical potential. She is known particularly for her work on mammalian respiratory complex I (NADH: ubiquinone oxidoreductase), an energy-transducing, mitochondrial redox enzyme of fundamental and medical importance, and for solving its structure by electron cryomicroscopy.[13][14]
