About Me


Sam MartinSam Martin is a Ph.D. researcher in Centre of Interdisciplinary Methodologies at the University of Warwick. She has an MSc in Digital Sociology from Goldsmiths University (2012) and a BA and MA in Law from Oxford University. Prior to pursuing her Ph.D., she worked extensively in the field of E-Learning and Web Development at University College London, Manchester University (where she is an Honorary fellow) and Kings College London. She specialises in Data Mining, Data Visualisation, Digital Cartography, and the impact of Health in the use of Social Media in the City. Sam has created several mobile health apps aimed at helping patients with Coeliac Disease find Gluten Free food in London and Paris. She has also researched the rise in abusive patterns of behaviour on Twitter.


Gluten Free Tweets in New York and LondonMy doctoral research explores how individuals’ online interactions inform their health-navigation of the city. The working title of my study is: Twitter: Re-Writing The City Landscape With Health Knowledge. With the case study of Coeliac Disease, my research aims to understand and visualise the way patients share information on Twitter about where to find gluten free food in the daily self-management of their chronic illness.

I use data mining techniques to mine the Twitter API for health-related hashtags that include key terms that Coeliac patients use when discussing their gluten free diet or seeking advice via Twitter. These include the hashtags: #coeliac #celiac #glutenfree and other related terms. Data will be harvested from a 15 km radius of the cities of London and New York, and my research will include a comparative analysis of the knowledge and food-seeking behaviour of Coeliac patients between the two cities.

My research uses co-word and sentiment analysis to quantify to what extent patients use Twitter as a knowledge finding, decision-making or risk aversion tool. I visualise this flow of patient interaction through Twitter by using GIS and digital cartography techniques to create virtual maps of health annotations that compare behaviour in the cities of London and New York. My research is co-funded by, a Warwick University and WCPRS Collaborative Studentship; a Postgraduate Research Fellowship from Coeliac UK; and is in partnership with New York University’s CUSP (Centre for Urban Science and Progress).
