The Power of Mathematical Modelling - Nira Chamberlain FORS

Nira Chamberlain FORS, Senior Data Scientist at Holland and Barrett

Abstract: In the book Burnham, K. P.; Anderson, D. R. (2002), Model Selection and Multimodel Inference: A Practical Information-Theoretic Approach (2nd ed.) it is stated that a model is a simplification or approximation of reality and hence will not reflect all of reality. George Box (one of the greatest 20th century statistical minds) noted, “All models are wrong, but some are useful.” While a model can never be “truth,” a model might be ranked from very useful, to useful, to somewhat useful to, finally, essentially useless. In a recent commercial conference an anonymous director expressed the opinion that “all predictions are either wrong or luck”.
In this talk, I will highlight the “Power of Mathematical Modelling”. It can be argued if the French mathematician could predict the existence of a Black Hole in the 18th century (something he could not see), then how much can we predict things we can see in the 21st century!
Much of mathematical modelling occupies that unique overlap between the great subjects applied mathematics and operational research. It has a long history of success across many different industrial sectors. What other subject can teach biology to biologist, economic to economics, sociology to sociologist etc. Through the rise of machine learning, the face of mathematical modelling may be changing; mathematical modelling has always been a subject that evolved through time. However, one thing remains a model has a better chance of being useful if it is transparent and challengeable. There will be a demonstration of a number of models including can we use mathematical modelling to stop an artificial intelligence takeover.

Bio: Dr Nira Chamberlain FORS is the senior data scientist at Holland and Barrett, a Visiting Fellow at Loughborough University and is listed by the Science Council as “one of the UK’s top 100 scientists”. He was cited for developing mathematical modelling applications for industry. In 2015 he joined the exclusive list of 30 UK mathematicians who are featured in the autobiographical reference book Who’s Who and in 2020 he will become the President of the Institute of Mathematics and its Applications (IMA). Nira’s PhD thesis “Extension of the Gambler’s Ruin Problem played over Networks” was obtained from Portsmouth University in 2013, which he studied part –time while working as a full time Mathematics consultant.
As well as this, Nira is one of the few British mathematicians to have been discussed in the US book The Encyclopaedia of Mathematics & Society, which highlights two of Nira’s mathematical models and their impact in the field of supportability engineering of complex assets including the Royal Navy Aircraft Carrier - HMS Queen Elizabeth.
He has more than 25 years of experience of writing mathematical models/simulation algorithms that solve complex industrial problems. He’s developed mathematical solutions within many industrial sectors, including spells in France, the Netherlands, Germany and Israel.
Cited by the Powerlist 2018 and 2019 as one of the Top 100 Most Influential Black people in the UK. Winner of title The Aperiodical "World Most Interesting Mathematician" - an internet international mathematics communication competition.

Very brainy Mathematician. We met at Loughborough University in 2001 opposite the Uni Library. He was then doing some work for British Gas. Nice guy to chat with.

Had to stop watching after he annoyingly ended every sentence with "yeah".
