Abstract
Aim This study analyzes 35 publications by Maryam Mirzakhani from 1995 to 2016, focusing on her research output and collaboration with 20 co-authors. Background Maryam Mirzakhani was an outstanding Iranian mathematician and the first woman to win the “Fields Medal’’. This award is one of the highest honors in mathematics and is often compared to the “Nobel Prize”. Results She has authored a total of 35 publications, including 15 single-authored and 20 co-authored works. Her research career began early, with her first paper published in 1995 at the age of 18. Her most productive period was between 2010 and 2014, during which she published approximately three papers per year while aged 33 to 37. Notably, her productivity coefficient peaked at 1.0 in the years 1999, 2009, 2011–2012, and 2014–2015. Among her collaborators, A Eskin was the most active or core collaborators. She used 26 communication channels to disseminate the results of her research of which arXiv preprintar Xiv (a preprint server) (6 papers) top of the list followed by Annals of Mathematics (2), International Mathematics Research Notices (2), Inventiones Mathematicae (2), and Journal of Modern Dynamics (2). Her publication concentration is measured at 53.85, with a publication density of 1.35. The most commonly used keywords in her research are “Moduli space” (appearing nine times) and “Hyperbolic surfaces” (six times), reflecting her primary areas of scholarly focus. Conclusion Her achievement made history and inspired many people around the world, especially women, to study mathematics. Her untimely demise is a universal loss in mathematical research.

INTRODUCTION
Female scientists have played a major role in the development of mathematics, even though historically they faced barriers such as limited access to education, social restrictions, and lack of recognition. Their contributions have helped shape many areas of modern mathematics. Here are some key roles and impacts (O’Connor & Robertson, 2008; Murray, 2016; AMS, n.d.). Many women have made groundbreaking mathematic discoveries and theories such as Hypatia (4th–5th century) was one of the earliest known female mathematicians and contributed to astronomy and geometry. Emmy Noether made fundamental contributions to abstract algebra and theoretical physics. Her work led to Noether’s Theorem, connecting symmetry and conservation laws. Sofia Kovalevskaya contributed to analysis, differential equations, and mechanics.
Women have helped develop and expand several modern mathematical disciplines. This includes Maryam Mirzakhani, made major contributions to geometry and dynamical systems and became the first woman to win the Fields Medal in 2014. It also may include a name that is Neena Gupta, a Kolkata-based female mathematician who won Infosys Prize in 2014 for Cracking the Zariski Code, one of Math’s long-lasting problems. Apart, Julia Robinson, American mathematician, played a key role in solving Hilbert's Tenth Problem, a famous question in number theory and logic. Female mathematicians have worked as professors, mentors, and researchers, inspiring future generations and contributing to mathematical education and academic institutions. For example, an American mathematician, Katherine Johnson, used advanced calculations to help guide space missions for NASA, demonstrating how mathematics can be applied to real-world scientific challenges. Women mathematicians have also helped break stereotypes and encourage more girls to pursue mathematics and science. Their success has led to initiatives promoting gender equality in STEM fields. Female scientists in mathematics have contributed to theoretical discoveries, applied mathematics, education, and social progress. Despite historical obstacles, their achievements continue to inspire new generations and strengthen the development of mathematics worldwide.
This episode starts along with the Maryam Mirzakhani, an Iranian mathematician and a professor of mathematics at Stanford University who was considered to be one of the history’s great mathematicians. Her research topics include Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry. Mirzakhani won the Fields Medal in 2014, the highest and prestigious award in mathematics, equivalent to the Nobel Prize, for her outstanding work on the dynamics and geometry of Riemann surfaces and their moduli spaces (McMullen, 2014; Peer, n.d.; White, 2017; AMS, 2017). Till today, Mirzakhani was the only woman as well as the first Iranian who received the Fields Medal since its inception in 1936. She was known to her colleagues as a genius in the dynamics and geometry of complex surfaces (“science-fiction- mathematics”), and as an artist to her young daughter, Anahita. In her own home, when Mirzakhani would spend many hours on the floor with large paper and draw casually on the paper, and write mathematical formulas around the drawings, seeing this her daughter exclaimed her mother was "painting” (Math.standford.edu, n.d.; Wikipedia, 2017). According to Mirzakhani’s speeches (Lamb, 2017), she did not grow up to be a mathematician. When she was child, she loved to read and make up stories and thought she might be a writer. During the period of middle school, she eventually discovered a passion for mathematics and proved to be brilliant at it. Finally, she became a pioneer in mathematics. It is to be noted that Artur Avila, Manjul Bhargava, and Martin Hairer (all males) were also awarded the 2014 Fields Medal, along with Maryam Mirzakhani (IMU, 2015).
LITERATURE REVIEW
Over the years, many bibliometric and scientometric studies have been carried out by librarians and information scientists to analyze the research contributions of well-known scholars from different fields. These studies show a continued interest in measuring the academic impact and intellectual output of eminent personalities. Harold W. Kroto was studied by Kademani et al. (2002), who analyzed his research output. Sen and Karanjai (2003) prepared a bibliometric profile of Biman Bagchi. Srimurugan and Nattar (2008) examined the research productivity of K. Veluthambi. Sangam and Savanur (2010) conducted a study on Eugene Garfield, a key figure in bibliometrics and scientometrics. Mukherjee (2013) analyzed the work of Lalit Singh. Manjunath and Ramesha (2015) studied C. V. Raman, focusing on his life and scientific contributions. Koley and Sen (2016) analyzed the work of V. L. Kalyane, who is well known for conducting many bibliometric studies. Mondal, Raychoudhury, and Sarkhel (2018) presented a profile of P. C. Mahalanobis. Dutta (2019) documented the academic contributions of B. K. Sen. In recent years, the scope of such studies has expanded further. Teli and Maity (2021) analyzed Stephen Hawking. Huded et al., (2023) studied Madhav Gadgil. Koley (2024) extended this work to include personalities from law and mathematics, such as Fali Sam Nariman and Raj Chandra Bose. Behera and Meher (2024) examined the scholarly impact of Raghuram Rajan. Most recently, Koley (2025) studied Suprabhat Mukherjee. In the same year, Koley and Goswami (2025) analyzed the contributions of Somenath Dutta, who is recognized for his work on micro-RNA therapy to prevent harmful Zika virus effects related to liver cancer. In 2024, Victor Ambros and Gary Ruvkun received the Nobel Prize for their discovery of microRNA and its function in gene regulation (Nobelprize.org, 2024), work that aligns closely with Dutta’s research.
These studies show that bibliometric research is expanding across many disciplines. However, to the best of my knowledge, no biobibliometric study has yet been conducted on Maryam Mirzakhani, the first woman Fields Medal winner. This gap creates an important opportunity to evaluate her research output and impact, making such a study both timely and valuable for the field of mathematical sciences.
Early Life and Education
Mirzakhani, a Persian woman, was born on 3 May 1977 in Tehran, Iran. Actually, she was anIranian, later she took nationality of America. Her father was Ahmad Mirzakhani, an electrical engineer and mother Zahra Haghighi (ResearchGate, 2017; Mirzakhani M., 2017; CV, n.d.).She was married in 2005 to Jan Vondrak, a Czech computer scientist at IBM, and an associate professor of applied mathematics at Stanford University, and their daughter is Anahita (now six, born 2011). As Vondrak was not a Muslim, the Iranian government did not recognize their marriage. She lived in Palo Alto, California, United States(Roberts, 2017; Wikipedia, 2017). From her childhood, Mirzakhani was very much interested to write fictions. Yet, her talent as a mathematician looked automatic from very young age. She went to high school in Tehran at Farzanegan, National Organization for Development of Exceptional Talents (NODET). While as a teenager, Mirzakhani won gold medals in the 1994 and 1995 International Mathematical Olympiads for high school students, attaining a perfect score in 1995. She became the first Iranian student to achieve perfect score and to win gold medal. In 1999 she received BSc degree in mathematics from the Sharif University of Technology in Tehran. She then went to the United States for her PhD from Harvard University, where she worked under the supervision of the Fields Medalist Curtis T. McMullen. Five years later she earned a PhD in 2004 from the University for her thesis “Simple Geodesics on Hyperbolic Surfaces and Volume of the Moduli Space of Curves” (Wikipedia, 2017; CV, n.d.; AMS, 2017; Myers & Carey, 2017; Phippen, 2017).
Professional Career
Mirzakhani served the Clay Mathematics Institute as a research fellow (2004-08) and an assistant professor at Princeton University. She also joined the faculty of Stanford University in 2008, where she served as a professor of mathematics until her death in 2017 (Wikipedia, n.d.; Math.standford.edu, n.d.; Wikipedia, 2017). This apart, she used to deliver invited lectures at Yale and Rice University and has given several invited talks during 2005-2006. She worked as a referee for Duke Mathematical Journal, Journal of Differential Geometry, Mathematical Research Letters, United States Israel binational scientific foundation; organizer for: Teichmuller Theory and Kleinian Groups August 20, 2007 to December 14, 2007, Mathematical Sciences Research Institute, Berkeley, CA (Wikipedia, n.d.; AMS, 2017).
Research Contributions
Mirzakhani was a highly original mathematician and made significant contributions to geometry and dynamical systems. Her work encompasses several mathematical disciplines such as hyperbolic geometry, complex analysis, topology, and dynamics. She gained recognition for her early discoveries in hyperbolic geometry i.e. the "prime number theorem for simple closed geodesics." The viewpoint developed in that work led to a proof of a conjecture that had been made by string theorist Edward Witten (1990 Fields Medalist). The conjecture was first proved in 1992 by Maxim Kontsevich (1998 Fields Medalist); 15 years later, Mirzakhani provided a new proof that came from a very different and totally unexpected viewpoint. These works led her to the study of dynamical systems associated with spaces of Riemann surfaces, where she and her collaborators made fundamental breakthroughs. Her more recent work (with A. Eskin and A. Mohammadi) constitutes one of the most sought-after advances in the area known as Teichmüller dynamics. She proved a rigidity theorem that is an analogue, in this non-homogeneous context, of the celebrated Ratner rigidity theorem in homogeneous dynamics (Wikipedia, 2017; McMullen, 2014; AMS, 2017).

METHODOLOGY
This study covers 35 publications of Mirzakhani published in national and international communication channels during 1995-2016. The publication year of two works is unknown. Mirzakhani has published numerous papers across journals and conference proceedings. By consulting sources such as Google Scholar, her research guide’s records, her curriculum vitae, preprint servers (e.g., arXiv.org), the Scopus database, ResearchGate, and other formal channels, a list of 35 publications was compiled.
Statistical Analysis
The data collected from Mirzakhani’s publications were organized and analyzed using Microsoft Excel and Word. Descriptive statistics such as total publications, authorship patterns, journal distribution, and citation counts were calculated. Bibliometric indicators including authorship count, collaboration index, and publication trends were derived to quantify her research output and impact. For authorship, each contributor was given full credit regardless of their position as primary author or co-author.

Validation of Lotka’s Law
An analysis of the co-authorship data reveals that out of 21 individual collaborators, 14 co-authors (66.66%) have contributed to only one publication, while 5 co-authors (23.81%) have authored two papers, and 1co-author (4.76%) have contributed to eight papers. The frequency of authorship exhibits an inverse square relationship typically described by Lotka’s Law, which states that the number of authors publishing n papers is about 1/n² of those publishing a single paper.

Publication Density (PD) and Publication Concentration (PBC)
PD is the frequency of papers per channels is found to be 1.35, whereas 50% of the contributions 18 appeared in first 14 communication channels, and thereby PBC is 53.85 [i.e. (14÷26) x 100].
Bradford’s Law
According to Bradford’s Law, if journals (or channels) are arranged in descending order of productivity, they should form zones containing approximately equal numbers of articles, and the number of journals in each zone should follow a geometric progression of the form 1 :n : n².
In this case, although the total of 35 papers is divided into three zones, the distribution is uneven: the first zone contains 12 papers (32.28%) across 8 channels, the second zone contains 17 papers (48.57%) across 11 channels, and the third zone contains 7 papers (20%) across 7 channels. These percentages do not approximate the expected one-third (≈33.33%) distribution per zone, particularly with the second zone being disproportionately large and the third zone significantly smaller. Furthermore, the ratio of communication channels across the three zones (8 :11 : 7) simplifies to approximately 1 :1.4 : 0.87, which does not follow the required geometric progression (1 :n : n²). Instead of increasing multiplicatively, the number of channels fluctuates irregularly, with the third zone even showing a decrease rather than the expected expansion.
Therefore, due to both the unequal distribution of articles among zones and the failure of channel ratios to follow a geometric progression, the dataset does not satisfy the fundamental conditions of Bradford’s Law.

DISCUSSION
During 1995-2016, she has produced 35 papers in total, out of which two papers do not have date of publications. However, out of them, Mirzakhani is the first author in 8 papers, second author in 10 papers, third and fourth author in one paper each. Overall, she has published 12 papers as co-author. Mirzakhani’s first paper was published when she was 18 and her scientific productive life spanned 22 years. The 50-percentile productivity life was 17 while chronological age was 34. During 1997, 2000 to 2002 and 2004-2006, there was no publication. It is also observed that she has produced the largest number of papers as single author (n=15). Mirzakhani’s maximum single-authored papers are 8, produced during 2007-2016. Most of the collaboration took place during 2008-2016. Of the collaborated papers, maximum are first- and second-authored papers. During 1999, 2009, 2011-2012 and 2014-2015, all her papers were collaborative and hence collaboration coefficient was one. Overall, it is 0.57.
This distribution of co-author’s publications aligns with Lotka’s Law, which suggests an inverse-square relationship between the number of authors and their productivity. Hence, the data set in Table 4 supports Lotka’s Law.
The dataset does not conform to Bradford’s Law because results show that the distribution of articles across communication channels deviates significantly from the expected pattern.
In the first quinquennium of her active carrier, her productivity was 1 per year which gradually increased up to 2.4 in fourth quinquennium 2010-2014 (age 33-37) and peaked. After that it declined and she did not complete the last quinquennium (Table ) due to her untimely death in 2017. Year of publication of last two papers could not be ascertained.
The author contributed 15 papers without any collaboration during her productive career. The rest 20 papers are produced with collaboration. Of the collaborative papers, 12 were two-authored, 5 three-authored, 2 four-authored and only one was five-authored. Among the collaborative papers, two-author collaboration has generated the largest number of papers i.e. 12 with the time span of 22 years. Three-author collaboration has generated five papers in a time span of six years, four-author collaboration two papers and five author-collaboration one paper in a time span of one year. As year of publication could not be ascertained for one each of one- and four-authored papers, figure of span in one-authored paper has been shown excluding one year and of span in four authored papers could not be ascertained.
In case of by line status, Mirzakhani appeared as the second in the highest number of papers i.e. 10. She occupied the first position in eight, third and fourth position in one paper each. She had no paper as fifth author.
Mirzakhani collaborated with 20 researchers till 2016 and produced as many as 9 papers in collaboration with A Eskin. A Eskin had seven papers as main and two papers as co-author during 2011-2015. A group of five collaborators of Mirzakhani includes J Athereya, A. Bufetov, A Mohammdi, J Vondrak, and A Wright and they produced two papers each. Another group of 14 collaborators had one paper each.
Mirzakhani used 26 communication channels to disseminate the results of her research of which arXiv preprint arXiv (a Preprint server) tops of the list (6 papers) followed by Annals of Mathematics (2), International Mathematics Research Notices (2), Inventiones Mathematicae (2), and Journal of Modern Dynamics (2). Here, publication concentration, and publication density are to be as 53.85 and 1.35 per year respectively.
Majority of her papers appeared in American journals. Her publications also emanated from UK, Germany, Switzerland, Canada, Iran, and India.
The keyword Moduli space ranks first indicating her concentration on the topic. This is followed by Hyperbolic surfaces (n=6). Weil-Peterssonvolumes (n=5), Closed geodesics (n=4), and Curves (n=3). These apart, another 41 keywords have been used only once in the titles of her publications.
CONCLUSION
Maryam Mirzakhani demonstrated a remarkable and focused research trajectory, reflected in her total of 35 publications, comprising 15 single-authored and 20 collaborative works. She began her scholarly journey at an exceptionally young age, publishing her first paper in 1995 at just 18. Her most productive phase occurred between 2010 and 2014, when she consistently produced around three papers per year during the age range of 33 to 37, highlighting a period of sustained intellectual maturity and output.
Her productivity coefficient reached its peak value of 1.0 in multiple years—1999, 2009, 2011–2012, and 2014–2015—indicating periods of optimal scholarly contribution. Among her collaborators, Alex Eskin emerged as her most significant and frequent research partner, playing a central role in her collaborative work.
Mirzakhani disseminated her research across 26 communication channels, with arXiv leading as the most utilized platform (6 papers). Other prominent journals include Annals of Mathematics, International Mathematics Research Notices, Inventiones Mathematicae, and Journal of Modern Dynamics, each contributing two publications.
Her publication concentration was calculated at 53.85, with a publication density of 1.35, indicating a relatively focused yet impactful dissemination pattern. The most frequently occurring keywords in her work “Moduli space” (nine occurrences) and “Hyperbolic surfaces” (six occurrences) underscore her deep engagement with complex geometric structures, firmly establishing her as a leading figure in modern mathematical research.
Her achievements, crowned by the prestigious Fields Medal in 2014, stand not only as a personal triumph but also as a beacon of possibility for future mathematicians. Even in the face of adversity, she remained committed to knowledge and discovery, embodying the true spirit of scientific inquiry.
Mirzakhani was very modest, and hesitant to take credit. After achieving the Fields Medal in 2014 she acknowledged saying, “I will be happy if it encourages young female scientists and mathematicians” (Phippen, 2017). She was diagnosed with breast cancer in 2013. In 2016 the cancer spread to her bone marrow and liver. It is extremely sad to note that the most prolific and the brightest young star in mathematics died on 14 July 2017 at the age of 40 at a hospital in California (Wikipedia, 2017). Her untimely demise is a universal loss in mathematical research. This study is offered as a humble tribute to her extraordinary life and contributions. It also carries a message of deep respect and sympathy to her loved ones, especially her daughter Anahita, whose mother’s legacy will forever illuminate the path of mathematical research. In remembering Mirzakhani, the global academic community honors not just a remarkable mathematician, but a timeless inspiration whose light continues to guide and uplift the world of science.
