Rosemary Ann Sexton PhD (born 16 July 1977) is a mathematician, athlete, sports therapist, osteopath, writer and musician. She had a distinguished career in mixed martial arts (MMA), from which she retired in 2014. [1][2][3][4][5][6]


Rosi Sexton was born in Versailles, France but moved to Britain at a young age, and grew up and received her education in the United Kingdom. She attended Kendrick School, Reading. Her father commented "what consistently runs through Rosi’s life is winning: she has a need to win. Her physics teacher said ‘Rosi has a meticulous approach to her studies and nothing short of perfection satisfies her' ".[7]


Sexton was an accomplished musician. She played with the Reading Youth Orchestra while at school (from 1991 to 1995). She reached grade 7 in cello and grade 8 in piano, then became an Associate of the London College of Music (piano).[8] In November 1994, aged 17, she played in the Royal Albert Hall, with the Reading Youth Orchestra.[9] She also played the organ ("though I never got very good").


In 1995, Sexton was admitted to Trinity College, Cambridge, where she took a first class degree in mathematics (1998). Her tutor in mathematics was Tim Gowers. She preferred pure maths: her particular interests were logic, combinatorics and number theory. She then moved to the University of Manchester, where she achieved an MSc in mathematical logic in 2000, The use of the Frame Theoretic Assembly as a unifying construct.[10] She went on to complete a PhD in Theoretical computer science, A point-free and point-sensitive analysis of the patch assembly.[11] Her supervisor was Harold Simmons in the School of Mathematics, with whom she wrote a paper, "Point-sensitive and point-free patch constructions", in the Journal of Pure and Applied Algebra.[12]

Martial Arts

Sexton had been involved in martial arts since she was at school. She already held dan grades in jujutsu and Tae Kwon Do. In 2000, after 10 years' experience in martial arts, she decided to train in Mixed Martial Arts and Brazilian Jiu-Jitsu, as a way of proving to herself that what she had learned was applicable to real life. A clue to the reason for this career change may be found in her comment "The other things I did, the music, the maths, just weren't quite hard enough"[7]

At the same time, she trained in osteopathy, receiving a degree in that subject from Oxford Brookes University in 2010. She currently practices as an Osteopath in the Manchester area, with a particular interest in sports injuries and evidence-based practice. She has written about the problem of performance-enhancing drugs (doping) in combat sports, and is a supporter of the Voluntary Anti-Doping Association, VADA.[13] She is a spokesperson for SafeMMA,[14] an organisation dedicated to ensuring safety of competitors, and she runs a combat sports injury clinic.[15]

Mixed martial arts career

Early career

Sexton made her mixed martial arts debut on 11 May 2002. She won her first five fights before moving up in weight to face Gina Carano on 15 September 2006. Sexton was defeated by knockout late in the second round.


Sexton debuted for BodogFight on 16 December 2006 and upset Brazilian submission specialist Carina Damm with an armbar late in the first round.

On 17 February 2007, Sexton faced Japanese striker "Windy" Tomomi Sunaba at a BodogFight event in Costa Rica. Sexton won the fight by Technical Decision in the second round after Sunaba suffered a serious ankle injury.[16]

Sexton fought once more for BodogFight and submitted Julia Berezikova on 24 August 2007.


Sexton signed an exclusive three-fight contract with Elite XC in June 2008.[17] She faced Debi Purcell at the 15 August 2008 ShoXC event in Friant, California and defeated Purcell by split decision.[18]

Following the demise of Elite XC, Sexton debuted for Bellator Fighting Championships at Bellator 12 on 19 June 2009. She submitted Valerie Coolbaugh with an armbar in the first round.[19]

Sexton was scheduled to face Angela Magana at CWFC 37: Right To Fight on 22 May 2010,[20][21] but Magana suffered an injury and Sexton was matched against Emi Fujino.[22] However, due to Sexton's re-signing with Bellator,[23] her CWFC fight was cancelled.[24]

Sexton faced Zoila Gurgel at Bellator 23 on 24 June.[25] She was defeated by knockout exactly two minutes into the first round.[26]

As a result of the knockout loss, Sexton was given a 60-day medical suspension and did not compete in the Bellator women's 115-pound tournament.[27]

Sexton was scheduled to face Sheila Gaff at Cage Warriors Fighting Championship 43 on 9 July 2011 for the Cage Warriors Women's Super Flyweight Championship at 125 pounds.[32] However, she suffered a concussion during training and was forced to withdraw from the fight.[33]

On 2 June 2012, Sexton faced Aisling Daly at Cage Warriors Fighting Championship 47. The bout was part of a tournament to crown a Cage Warriors 125-pound women's champion.[34][35] Sexton defeated Daly by unanimous decision to advance to the tournament final.[36]

Sexton was scheduled to face Sheila Gaff in the finals at Cage Warriors Fighting Championship 49 on 27 October 2012 in Cardiff, Wales. Voluntary Anti-Doping Association (VADA) drug testing was used in the weeks prior to the planned fight.[37] However, the bout was cancelled on 19 October when Gaff withdrew due to illness.[38]

Ultimate Fighting Championship

Sexton moved up in weight to make her UFC debut in Winnipeg, Manitoba, Canada on the UFC 161 card against Alexis Davis on 15 June 2013.[39] Sexton lost the fight by unanimous decision.[40]

On 26 October 2013, Sexton returned to the Octagon and faced Jessica Andrade at UFC Fight Night 30.[41] She lost the fight via unanimous decision.[42][43] Sexton was released from the promotion shortly after the fight.[44]

On 21 June 2014, Sexton announced her retirement from MMA competition.[45]
