Exploring the tau statistic

Visceral leishmaniasis spatiotemporal modelling
I joined the MathSys CDT MSc/PhD programme in September 2015 and in September 2016 began a PhD in infectious disease modelling with supervisors Mike Tildesley, Déirdre Hollingsworth & Lloyd Chapman. My PhD will model the epidemic cycles of VL in the Indian subcontinent (also presented as a poster at the NGCM summer academy in June 2016). In January 2017 I was awarded a Newton Bhabha PhD placement grant to fund a four-month visit to an Indian research institution from August - November 2017 under the guidance of Dr N Siddiqui; this has led to the collaborative Impact of intensified control strategies on incidence of visceral leishmaniasis in a highly endemic district of Bihar, India (Epidemics, May 2022)Link opens in a new window. I am particularly keen to work with researchers from the Indian subcontinent, so please do get in touch. I assisted with the data cleaning towards Inferring transmission trees to guide targeting of interventions against visceral leishmaniasis and post-kala-azar dermalLink opens in a new window leishmaniasisLink opens in a new window (PNAS, September 2020).
October 2014: Screening & data extraction phases of a systematic review of S.pneumoniae serotype carriage globally, in parallel with my colleague, Riya Moodley. This study, managed by Olivier Le Polain at LSHTM and with involvement from other CMMID members, will record serotype prevalence by geographic region. Combined with invasive pneumococcal disease estimates, it will estimate the impact of polysaccharide conjugate vaccines.
I digitised situation reports during the Ebola epidemic 2014/5 that contributed to real-time forecasts and Temporal Changes in Ebola Transmission in Sierra Leone and Implications for Control Requirements: a Real-time Modelling Study.
My laboratory research project in summer 2014 assessed the effectiveness of combining indoor residual spraying with bednets in Sudan, through the measurement of specific malarial antibody titres.
Research study group on Convex Optimisation in communications (Apr-Jun 2016). cvxpy Python code of communication examples by Gowers, Al-Izzi, Pollington, Hall & Briggs, based on problems from Boyd & Vandenberghe's Convex Optimisation book:
- Maximising the channel capacity (Jupyter notebook) (source code)
- Power assignment in a wireless communication system ie maximising the minimum SINR (Jupyter notebook) (source code)
- Optimal power and bandwidth allocation in a Gaussian broadcast channel channel (Jupyter notebook) (source code)
- Water filling (Jupyter notebook) (source code)
Read more about our project experience from a magazine article featured in the Warwick Centre for Complexity Science Newsletter, Summer 2016 (p4). A detailed article on our Convex Optimisation project can be read online on the Mathematics Today website or a standalone PDF of the article published in Mathematics Today magazine August 2018 issue.
