Overview The GSK Oncology team is seeking a highly motivated computational biologist to play a pivotal role in shifting our understanding of cancer. While many models in oncology focus solely on predicting outcomes, we are dedicated to developing new approaches that understand disease not as static labels or endpoints, but as dynamic, evolving biological states. By integrating (bulk, single cell and spatial) multi-omics and clinical data, you will characterize disease heterogeneity, model how disease changes over time and under treatment, and investigate how biological context influences treatment response and resistance. This work focuses on understanding, and ultimately shaping, disease trajectories in a biologically meaningful way, directly supporting GSK's ambitious goal to deliver transformative oncology therapeutics to patients. You will work at the interface of data, biology, and experimentation, tackling real questions in close collaboration with experimental and clinical teams, with the goal of making data-driven approaches more interpretable, robust, and actionable. In this role you will Analyze and integrate complex multi-omics and clinical data to characterize disease heterogeneity and drive decision-making insights. Develop and apply advanced models that capture disease states and their evolution, to predict and influence disease trajectories. Investigate how biological context and underlying mechanisms influence treatment response and resistance. Collaborate closely with experimental scientists to generate and test mechanistic hypotheses, translating complex data into actionable insights for drug discovery. Contribute to the development of frameworks and computational tools that support better therapeutic decision-making and advance our oncology portfolio. Communicate complex scientific findings clearly to both technical and non-technical audiences, acting as a subject matter expert within interdisciplinary teams.
