Optimisation and Data Analytics | University of Essex

You are viewing our beta course page.

Course summary

Our MSc Optimisation and Data Analytics will appeal if your first degree included mathematics as its major subject. We expect you to have prior knowledge of statistics – for example, significance testing or basic statistical distributions – and operational research such as linear programming.

Businesses, organisations, and individuals all strive to work as effectively as possible. Operational research uses advanced statistical and analytical methods to help improve the complex decision-making processes to deliver a product or service. Working in this field, you might be identifying future needs for a business, evaluating the time-life value of a customer, or carrying out computer simulations for airlines.

You specialise in areas including:

continuous and discrete optimisation
time series econometrics
heuristic computation
experimental design
machine learning
linear models

Our interdisciplinary research recognises that mathematics, including what can be very abstract mathematics, is an essential part of research in many other disciplines.

Our School of Mathematics, Statistics and Actuarial Science has an international reputation in many areas including semi-group theory, optimisation, probability, applied statistics, bioinformatics and mathematical biology.

Psychology
Hello! I am Caitlyn, I am a 1st year undergraduate student at the University of Essex. I study psychology with cognitive neuroscience and following my degree I intend to pursue either speech and language therapy or educational psychology. I am most passionate about helping others and trying to bring more joy to the world overall. University was such an unreal idea in my head originally as my family aren't well-off and nobody in my family had ever attended university before me - but here I am, and I would encourage others to take the plunge as well!

Politics
Hi, I am Charlotte, a third year politics with human rights student. I am also a member of the Student Union trustee board and a student representative alongside my studies, so I am very immersed in the student life here and more than happy to answer any and all questions you may have. I love to go out and I’m always attending the nightlife events on campus (maybe a little too much)! I am currently treasurer for the sustainable students society so if there’s anything you would be interested to know about societies, I can always let you know. I’m very friendly and bubbly so don’t be afraid to ask anything, no questions are silly.

Art History
I am a 29 y.o. PhD student in Art History & Theory with a background in Museum Studies (St Petersburg State University of Culture) and Curatorial Research (St Petersburg State University). I'm here to help you start your academic journey with the UoE. Ask me anything about PGR studies at Essex (especially PHAIS), financial support for international students, accommodation, life on and off campus (especially cultural events, e.g. museums, theatres, etc.) and what it's like to live in the UK/Colchester (e.g. what's there for people from my (and probably yours!) part of the globe. Fun facts about me: travelled to 40+ countries; have a cute little chinchilla named Pyshka🍩; have learnt that all the stereotypes about British weather are true—but it still rains more in St Petersburg, so I’m fine. 🥲

Modern Languages
I am a final-year student at the University of Essex's Colchester campus, so I have had a very long time here to come to know a lot of things about this place. Over my three years, I have had a broad range of experiences that university has to offer, from getting involved in sports and societies, to using the careers services, to completing a paid internship in a subject related to my degree. Applying to university, I knew that I wanted to study modern languages, but didn't study a language at A-Level, which definitely threw a spanner into a lot of things. As a 16/17 year old, I just didn't think that far ahead in my life- which is normal. I am living proof that, to an extent, this does not need to be the end of your plans to go to uni. As for me as an individual, I am interested in art and music- which I also make, and I also enjoy hiking, cycling and swimming on occassion. I'm also on the autistic spectrum. After graduating this year, my plan is to go and do a year working in a Spanish school, and then hopefully come back home and do a course on TEFL, all of which the academic staff are supporting me to do.
