Frenk is particularly notable for his work around galaxy formation, including his use of complex computer simulations to test theories on the origins and evolution of the universe, thus helping to resolve disputes among theoretical models. Among the most prolific and frequently cited authors in astronomy and space science, Frenk has written more than 500 scientific articles; he is a co-author on 5 of the 100 most cited papers ever published within his field.[2]
As a pioneer in computational astrophysics, Frenk, alongside Marc Davis, George Efstathiou, and Simon White, published a series of influential papers that established the validity of the cold dark matter hypothesis through computer modelling.
Elected a Fellow of the Royal Society in 2004, Frenk has received numerous awards and is regularly tipped as a contender for the Nobel Prize in Physics.
Early life and education
editCarlos Frenk was born in Mexico City, Mexico and is the eldest son of six siblings.[3] His father was a German Jewish doctor who emigrated from Germany at the age of 7, fleeing persecution in the lead up to World War II, while his mother was a Mexican–Spanish pianist.[4] As a youth, Frenk showed some talent for basketball and played semi-professionally. The other half of his life was devoted to mathematics.[5]
Frenk studied engineering at the National Autonomous University of Mexico but later changed to Theoretical Physics, earning his undergraduate degree in 1976.[1][4] He gained the highest marks in his year, and so was awarded the Gabino Barreda Medal.[5] He visited Italy, where he attended a guest lecture by Martin Rees, then a Professor at the University of Cambridge. Encouraged by Rees, Frenk abandoned his plan to study at Caltech and tried for Cambridge instead.[5]
That year he secured a British Council Fellowship and enrolled at the University of Cambridge to read Part III of the Mathematical Tripos, which he completed in 1977. He remained at Cambridge for doctoral studies under the supervision of Bernard J. T. Jones.[6] His doctoral research explored the properties of the Milky Way.[5] The idea of dark matter was still "extremely speculative" at this point, but Frenk concluded that the galaxy was surrounded with "embedded" dark matter.[5][a] He was awarded his PhD in astronomy in 1981.[8]
At Cambridge, Frenk decided to shift his research focus to cosmology because he felt there was still plenty of "exciting problems" within this field left to be solved; he thought particle physics was "moving rather slowly" and, despite help from professors, could not identify a suitable fundamental physics project for doctoral research that engaged his interest.[9] He met future collaborator Simon White for the first time at Cambridge. White, already a post-doc, acted as what Frenk later called his "unofficial supervisor".[5]
Career and research
editEarly career
editFollowing Cambridge, Frenk worked as a postdoctoral researcher at the University of California. He was based in Berkeley from 1981 to 1983, having been invited here by Marc Davis, an astronomer who had recently left Harvard.[5] He was then based in Santa Barbara from 1983 to 1984. He subsequently returned to the United Kingdom, where he was a postdoc at Sussex University from 1984 to 1985.[3]
The Gang of Four
editAt Berkeley, Davis needed Frenk, with his background in theoretical physics, to assist in interpreting his research — he had mapped 2,200 galaxies while at Harvard. Meanwhile, White had also moved to Berkeley.[5] This allowed the trio of Davis, White and Frenk to work together on what would prove to be a significant advance in astrophysics.[5]
The trio intended to use computer modelling to investigate the early state of the universe.[5] At this time, computational astronomy was a very new discipline.[5] In need of assistance, they recruited George Efstathiou, a recent PhD from Durham University, to help them.[5] Having become a foursome, the group worked on a series of papers — they were particularly interested in the supersymmetric theory that dark matter particles were "cold".[5] One of their first conclusions was that dark matter could not be made of neutrinos.[5] In 1985, they published their most significant paper in The Astrophysical Journal, entitled The evolution of large-scale structure in a universe dominated by cold dark matter, which revealed the results of the first simulations of cold dark matter.[10]
Once their research started to draw important results – despite the limited computing power available to them – Davis, White, Efstathiou, and Frenk came to be known as the 'Gang of Four' for the attention their arguments attracted.[5] The research produced by the Gang of Four confirmed the validity of the "cold dark matter theory" for the formation of galaxies and other cosmic structures.[3] While their arguments were not without their detractors, this would eventually become the accepted interpretation in cosmology.[3]
Move to Durham
editIn 1986, Frenk was appointed Lecturer at Durham University, having been recruited by Richard Ellis.[3][5] He found the physics department in Durham to be "tiny" upon his arrival, with "no theory" and astronomy "non-existent".[5] With Ellis' support he worked on strengthening the profile of the department in astronomical research; this was not easy, as Frenk struggled to access the computing power demanded by his computational approach.[5] He eventually secured a model from the MicroVAX series at a cost of £40,000, after trying and failing to borrow computers from commercial laboratories.[5] Frenk was promoted to Reader in 1991 and then made full Professor in 1993.[5] During this period of his career he turned down job offers from both the United States and Mexico.[11]
In spite of the impact created by their papers, Frenk and White's theories did not represent the scientific consensus at this time. They had been "under siege" during the late 80s and early 90s by academics who suggested alternative explanations to the concept of dark matter.[5] The most notable alternative theory was the Modified Newtonian dynamics proposed by Israeli physicist Mordehai Milgrom in 1981.[7] However, in 1993 evidence from the Cosmic Background Explorer offered further support for Frenk and White.[5][b]
Research efforts at Durham were boosted by the 1994 announcement of the High Performance Computing Initiative, which promised more resources from the government in future.[5] By now, White was based at the Max Planck Institute for Astrophysics, and he and Frenk joined their institutions with other computational astronomers to form the Virgo Consortium.[5][c] Crucially, this gave Frenk and his team access to the supercomputing centre of the Max Planck Society in Garching, regarded as among the best facilities in the world.[5]
Navarro-Frenk-White profile
editThe "paradigm of cold dark matter" had become firmly established by the mid-1990s; predictions of cosmological simulations therefore shifted away from the distribution of cold dark matter halos to the shapes of those halos.[10]
In 1996 and 1997, Frenk, White, and lead author Julio Navarro of the University of Arizona, published some remarkable results based on their analysis of halos from cold dark matter simulations.[10] These presented the Navarro-Frenk-White profile, a model profile for dark matter halos. Essentially, it is a spatial mass distribution of dark matter, fitted to the simulated dark matter halos. The formula and the related results are still widely used today, because NFW demonstrated that the size and density of dark matter halos are closely related to their mass in a way which depends on, and so can be used to measure the properties of our universe as a whole, for example, its material content and its mean matter density, as well as the properties of the initial conditions from which all cosmic structure has grown.[10]

Following an endowment from Computacenter founder Peter Ogden in 2001, Frenk was named the inaugural Ogden Professor of Fundamental Physics at Durham University and continues to hold this position today.[5][d] Frenk became the Director of the Institute for Computational Cosmology (ICC) upon its establishment in 2001. He held this post until 2020, at which point he was succeeded by Durham colleague Shaun Cole.[13][14]
In 2005, as a member of the Virgo Consortium, Frenk was part of a team that produced the Millennium Run, which was, at the time, the largest and most realistic cosmological N-body simulation ever.[15][5] It took 28 days to run.[5] In a later interview, Frenk summarised his cosmological simulation work as "cosmic cookery" because it depended on selecting just the right "ingredients", putting it into a computer, and letting it "cook".[16] He joked that he and his colleagues at the ICC had "filing cabinets" full of failed universes.[16]
By 2008 Frenk was one of the top 10 most cited astronomers in the world.[5] In 2020, Frenk was named a Clarivate Citation Laureate for his highly-cited research, which was judged to be of "Nobel Class".[17] Frenk, along with Julio Navarro and Simon White, was tipped as a potential winner of the 2020 Nobel Prize in Physics; though victory at a later date was considered a greater possibility given the award the previous year (to a team led by Princeton astrophysicist Jim Peebles) had been for work that was also within the realm of space science.[18] In 2021 the trio of Frenk, Navarro and White was again named as a strong contender for that years Nobel.[19][e]
Personal life
editFrenk is married to Dr. Susan Frenk, a lecturer in Spanish and Latin American literature and current Principal of St Aidan's College. They have two sons.[11]
Frenk has an interest in architecture, which was inspired by his experience studying at the main campus of the National Autonomous University of Mexico, a UNESCO World Heritage site.[21] He was unimpressed with the state of academic buildings when he first moved to Britain, describing them as "dark, claustrophobic and in a state of disrepair" and has taken an active role in the design process of new buildings at Durham University.[21]
Fellowships, awards and distinctions
editFrenk was elected a Fellow of the Royal Society (FRS) in 2004.[22] He was appointed Commander of the Order of the British Empire (CBE) in the 2017 Birthday Honours for services to cosmology and the public dissemination of basic science.[23]
He received the Gold Medal of the Royal Astronomical Society in 2014.[24]

edit- ^ In layman terms, dark matter is a hypothetical material said to make up 85% of space matter. Dark matter theory emerged as an explanation for why, contrary to Newtonian physics, almost all stars in a spiral galaxy race around the centre at the same speed, rather than moving more slowly the closer to the edge. This observation was first made by Vera Rubin.[7]
