I graduated from the University of British Columbia (Vancouver, Canada) with a BSc in Computer Science, Microbiology and Immunology. I then moved to the University of Cambridge for an MPhil in Computational Biology working on signalling pathways with Prof Jasmin Fisher (Microsoft Research), and a PhD in Biostatistics working on statistical genetics with Prof Lorenz Wernisch (MRC Biostatistics Unit).
Following the completion of my PhD in 2012, I undertook postdoctoral training to investigate genetic prognostic markers at the Princess Margaret Cancer Centre in Toronto with Prof Ming-Sound Tsao and Prof Frances Shepherd.
I was promoted to a staff scientist in 2013 to coordinate the genomic sequencing and bioinformatics analysis of patient tumours. With a greater interest in drug development, I went back to Cambridge in 2014 to join the early drug discovery division of AstraZeneca where I developed computational methods to identify pharmacological biomarkers that predict drug response.
I joined the Sheffield Institute for Translational Neuroscience, University of Sheffield in 2016 as a Lecturer (now Senior Lecturer) of Genomic Medicine and was jointly appointed to the Dept. of Computer Science in 2018.
I am also the Scientific Director of the Sheffield Bioinformatics Core and Genomics Theme Lead within the NIHR Sheffield Biomedical Research Centre.

- Research interests
My group focuses on translating the complex patterns of genomic data generated in the lab to enable the development of personalised medicines that can benefit patients suffering from complex diseases. Of computational interest, this involves integrating genomics information of various data types in order to build machine learning algorithms that predict clinical outcome and identifying biomarkers through feature selection.
Of biomedical interest, we survey the genomic landscape of disease subtypes using sequencing techniques to better understand how we can stratify patients for different treatments. Both of these aims enable us to work towards the ultimate goal of developing data driven approaches for personalising medicine
Genomic characterisation and stratification to enhance patient stratification.
In order to translate evidence from preclinical studies to the clinic, we must use multi-omic profiling to characterise in vitro, in vivo and patient samples used in drug development. In collaboration with Microsoft Research, we combined proteomics data to predict cell fate when perturbed by a combination of inhibitors.
We are also characterising the genomes of syngeneic mouse models (in collaboration with MedImmune) and patient-derived xenografts (in collaboration with Univ. of Toronto) to identify genetic markers of response to immunotherapies and targeted therapeutics.
We are testing our stratification approaches on the 100,000 Genomes Project cohort and collaborating with industry partners to improve genetic diagnostics (Genomics England, Personalis Inc.).
Probabilistic modelling to identify genetic features associated with clinical outcomes.
Reliable estimation of drug response in patients and their outcomes is an open problem for precision medicine. We collaborate with statisticians at Lancaster University, the AstraZeneca and the Sheffield Institute for Translational Neuroscience to use Gaussian Processes to estimate the uncertainty in treatment response metrics (eg. IC50s) in large screening experiments.
Also in collaboration with the Donald Heath Sheffield, Imperial College London and Cambridge University, we are using unsupervised and regression based methods to identify gene signatures that describe different subtypes of pulmonary arterial hypertension, a rare disorder.
Machine learning prediction of drug responses and drug combinations.
Large-scale in vitro screening of drug combinations are extremely costly and can only test a small proportion of all possible combinations. To help alleviate this problem, we have developed software tools to quantify drug synergy and helped launch the AstraZeneca-Sanger DREAM challenge for predicting drug combinations.
By stimulating computational scientists from around the world with a large experimental data set of drug combinations, we have sourced new machine learning methods that are highly predictive of synergistic drug combinations in different cancer types. Currently, we are assessing the translatability of these methods for predicting synergy in completely new drugs and combinations.
