Tom Collins - Head of Mathematics Faculty

Tom Collins worked in Management Consultancy and Corporate Finance before becoming a Mathematics Teacher. He studied Mathematics, Physics and Music at A-Level and went on to read Mathematics at Cambridge. His favourite theorem at A-Level is de Moivre's, which elegantly links many branches of Mathematics: complex numbers, trigonometry and the exponential function. In his spare time he enjoys classical music, fitness and sport- escaping as often as possible to the great outdoors. His most recent excursion was travelling to Helsinki and back around the Baltic Sea using only his bicycle (and the odd ferry).

Stephanie Birch - Teacher of Mathematics
Head of Turing House

Growing up in Western Australia, Stephanie Birch completed five A-level equivalent subjects and, like many students, struggled to narrow her interests to a single choice at university. While pursuing English and Drama would have indulged her love of reading, writing, and performance, and the sciences offered interest and intrigue, it was the beauty of Further Mathematics which lead her to complete a Bachelor Degree in Mathematical Sciences at Curtin University. Having always enjoyed the satisfaction of solving a difficult proof, and finding great enjoyment in the challenge of explaining complex concepts and solutions to her peers, pairing her Mathematics Degree with a Bachelor of Education was the natural progression of her interests (and squeezing in enough Literature units to earn an English minor provided tangents to explore beyond the mathematical). Mrs Birch has taught in a number of schools throughout Australia and England, and feels she has found a home away from home at Harris Westminster Sixth Form; soaking up all the wonderful history and culture that London has to offer. When not sight-seeing, Mrs Birch enjoys cooking, playing board games, and dispensing delightful fiction to her friends in doses just large enough to spawn an addiction to whichever realm of Fantasy she is currently adventuring through

Cyril Cannamela - Teacher of Mathematics

Cyril Cannamela worked for 20 years in finance, mostly trading equity derivatives products on shares dealt across the five continents. Throughout his career, he discovered Asia, living 5 years in Japan and 6 years in Hong Kong and travelling to many other countries in the region. He eventually decided to quit that world to teach Mathematics. Indeed, having graduated in the top "Grande École" in France, his interest for sciences never faltered over the years.
He is an experienced sailor and his main hobbies are listening to Jazz music, kite surfing and hiking, where his most exciting achievement was to climb Mont Blanc.

Eleonora Crestani – Teacher of Mathematics

Eleonora Crestani studied Mathematics at the University of Padova (the same one where Galileo taught) and completed her PhD there on Pure Maths in 2009. Between her PhD and starting teaching at Secondary school,  she has been an Assistant Professor in Italy and Visiting Researcher both in the UK and USA. During this period, she taught Calculus and Algebra  to Undergraduate Maths and Computer Science students but she mostly studied, did research and wrote papers on generation problems in groups and  probabilistic group theory. As well as maths, she loves reading, watching movies  and hiking especially on the Alps close to her hometown.

Treacy Hanley - Teacher of Mathematics

Treacy Hanley joined Harris Westminster in 2018. She grew up in Ireland and she studied at the National University of Ireland Galway. When she began university she studied Physics. However, after realising her love of pure mathematics and her dislike of experimental physics she changed to study Mathematics and Applied Mathematics. She enjoys algebra and her final year project was on the topic of Butson Hadamard Matrices. During her summers at university she taught English in Italy and took part in a research internship near Washington D.C. at the University of Maryland. She moved to London in 2017. In her spare time she enjoys performing in musical theatre, singing and drawing. She also enjoys swimming and cycling.

András Hraskó – Teacher of Mathematics

András Hraskó studied mathematics in Budapest and at the University of Warwick and obtained MSc and PhD degrees in Pure Mathematics. He is proud of having answered a question posed by the engineering faculty at MIT by understanding the elliptic curve underlying the physical problem. András has been teaching in secondary schools for 25 years and has written several books with students, with teachers and also with professors. He has given lectures and developed teaching materials, for example: about the mathematics of the CD disk; the application of the theories of modern physics in mathematics; and, on the mathematics of Renaissance Art. One of his students, Khalid Hassan, recently won a First Prize in the Bolyai Institute of the University of Szeged competition.  András used to teach problem solving for “future teachers” at the ELTE University Budapest for several years and regularly led sessions on the joint British Hungarian International Olympiad Training Camps. In his free time he reads history and literature, rides his bike and climbs mountains in Scotland, Wales, the Tatras, in the Alps and in the Caucasus. For several years he has also led groups of students on “hiking-biking” expeditions to different mountains through beautiful valleys.

Laura Inal - Teacher of Mathematics

Laura Inal joined Harris Westminster in 2017. She read mathematics at university and particularly enjoyed studying fluid dynamics. Following her degree she moved to Hampshire to work in sixth form colleges and specialise as an A level maths teacher. Having grown up in Norfolk, Laura enjoys spending time walking in the country side and partaking in clay pigeon shooting. She also loves to travel, with her favourite destinations so far being Ecuador and Hong Kong. 

Ewa Jinman - Teacher of Mathematics

Ewa Jinman read Mathematics at Warsaw University in Poland. During her degree programme she studied topics including Number Theory and Topology but her favourite was Differential Equations. Upon graduating she taught Mathematics in secondary schools and sixth forms. In addition she also taught English, with an emphasis on grammar, to secondary school students in Poland. She moved to England in 1997 and since then her teaching, and heart, has remained with Mathematics. Outside of school she enjoys travelling, reading about Psychology (especially the works of Malcolm Gladwell) and DIY. She also reminisces about her school days where she played netball and represented the school in handball.

Ben Leadbetter – Teacher of Mathematics

Ben Leadbetter joined Harris Westminster Sixth Form in 2015. He read pure mathematics at Bristol University, specialising in number theory, logic and complex algebra. Born and bred in North-East London, son to an artist and a musician and descended from the composer Lionel Bart, Mr Leadbetter deems maths to be a creative subject. He has numerous other interests besides mathematics including swimming, 80s disco, post-apocalyptic sci-fi, juggling, gastronomy, socialism and modern art.

Tanya Pearson – Teacher of Mathematics

Tanya Pearson studied Mathematics at the University of Warwick, during which time she spent a summer volunteering as a teacher in Tanzania. Whilst her main focus was pure mathematics, Tanya particularly enjoyed studying probability and statistics and completed her Second Year Essay on Markov processes and their applications in queuing theory. She also utilised the flexibility in her degree course to study modules from a range of departments including Philosophy, French and Education. Tanya taught mathematics in secondary schools in South London and has since worked as an actuarial consultant before joining Harris Westminster in 2016. In her spare time she enjoys playing five-a-side football and spending time by the sea in her hometown of Brighton.

Alex Ryzak - Teacher Mathematics and Economics

Alex Ryzak teaches Core Maths and Economics.  She studied Maths, Economics, Politics, English Literature and Chemistry at AS and A level and went on to read Philosophy, Politics and Economics at Magdalen College, Oxford.  Prior to becoming a teacher, she worked in business consulting.  Alex's love of academia was revitalised by undertaking a part-time masters, which convinced her to move into education full-time, as a teacher.  In her spare time Alex enjoys walking, baking and listening to Radio 4.
