Cough is the most common reason for which medical advice is sought both at primary and secondary health care levels. Despite the prevalence of cough, understanding of the mechanisms that lead to coughing in different diseases is poorly understood; this has made drug development for treatment of cough even more difficult. Cough challenge test using inhalation agents such as capsaicin has been used to induce and quantify cough with the aim of understanding the mechanisms that underline cough and assess efficacy of antitussive therapies. Capsaicin cough challenge test has been designed and tested by a multi-disciplinary research team (lead by Prof Jacky Smith) at the Manchester University NHS Foundation Trust, Wythenshawe.

The objective of this project is to develop mechanistic models for describing the data obtained from capsaicin cough challenge test. This model will allow better interpretation of the test, provide insight into the mechanisms of cough and boosts developments of antitussive therapies. It will also help to refine statistical design of the test.

During capsaicin cough challenge, to evoke cough individuals are administered four inhalations of doubling doses of capsaicin within a specified range of doses. The data from this study (number of coughs after each dose of capsaicin inhalation) is a discrete type of data and requires special technique for its analysis. Recently a mixed-effect model approach (Satia et al) was applied to this data taking into account its discrete nature, dose-response type and the drop-out by individuals at different doses of capsaicin. This model characterised capsaicin dose-response in patients with chronic cough, asthmatic patients, and healthy volunteers and was superior to traditional method of analysing this data. This research will explore other models that have been proposed for count data; also correlation between counts will be explored by using Markov models.

Entry Requirements

Applicants are expected to hold or about to obtain, a minimum upper second class undergraduate degree (or equivalent) in pharmacy, pharmacology, mathematics, statistics, biological sciences, engineering or a related biological/physical science area. A strong mathematical background and/or a Masters degree in relevant subject area are desirable. Previous experience of data analysis and mathematical/computational modelling would be an advantage. 

Funding Notes

This project is funded by The Faculty of Biology, Medicine and Health at the University of Manchester. Studentship funding is for a duration of four years to commence in September 2019 and covers UK/EU tuition fees and a UKRI stipend (£15,009 per annum 2019/20). Due to funding restrictions the studentship is open to UK and EU nationals.
