Project Description

Design and implementation of synthetic circuits for research and therapeutic applications.


We aim to decipher the logic of post-transcriptional gene regulation, harness this knowledge to create synthetic systems capable of rewiring or enhancing naturally evolved cellular behaviours, and use the emerging principles to advance the scope of somatic and stem cell engineering for basic research and therapeutic applications. Using an integrated approach, we currently endeavour to develop programmable signalling pathways and gene networks responsive to exogenous cues and/or endogenous metabolites. This research paves the way for the design of more sophisticated regulatory circuits enabling de novo implementation of custom cellular functions. Our scientific program is inspired by advances in miRNA biology, synthetic biology and genome engineering.

The recent breakthrough in genome engineering technologies (CRISPR/Cas9) marked the beginning of a new era of scientific discovery and molecular medicine applications. The relatively straightforward design and streamlined construction protocols developed for these technologies, together with continuous improvements to increase on-target efficiency and reduce off-target effects, now offer a realistic opportunity for genome engineering-based therapeutic applications. Most notably, the astonishing wave of innovations in this field has radically expanded the scope of ex vivo somatic and stem cell engineering from simple viral transgene expression to site-specific knock-ins, controlled gene disruption, and direct correction of disease-causing mutations. These groundbreaking studies have not only redefined the promise of cell-based interventions for multiple disease indications, but have also set the stage for the implementation of more sophisticated regulatory programs aiming to modulate cellular behavior and function.

The goal of this research project is to develop CRISPR-based synthetic devices suitable for gene and cell therapy applications in acquired and inherited human diseases. Achieving spatial‐temporal control over endogenous gene expression will be instrumental for understanding gene pathway architectures, as well as changes and choices in transcriptional programs operating during differentiation, development, and disease. Ultimately, our aim is to establish new experimental frameworks for programmed regulation and correction of protein levels, and apply these systems to develop cell-based therapies for blood disorders and cancer. Adding to a growing toolkit of standardised components, this conceptual framework will play a pivotal role in synthetic biology, empowering scientists to create complex systems able to challenge or reprogram cells upon sensing a disease state

The proposed project will be undertaken at University of Oxford’s MRC Weatherall Institute of Molecular Medicine, in a highly dynamic and competitive environment. The project will involve a broad range of cutting-edge technologies including CRISPR-Cas9/Cas13 genome engineering, digital PCR, next generation sequencing, advanced molecular biology, RNA biochemistry, FACS, lentiviral-mediated delivery, and computational biology. In addition, the student will be trained to develop writing and presentation skills, will have opportunities to present their work at conferences and attend at least one advanced training course.

As well as the specific training detailed above, students will have access to high-quality training in scientific and generic skills, as well as access to a wide-range of seminars and training opportunities through the many research institutes and centres based in Oxford.

The Department has a successful mentoring scheme, open to graduate students, which provides an additional possible channel for personal and professional development outside the regular supervisory framework. We hold an Athena SWAN Silver Award in recognition of our efforts to build a happy and rewarding environment where all staff and students are supported to achieve their full potential.

Funding Notes

Our main deadline for applications for funded places has now passed. Supervisors may still be able to consider applications from students who have alternative means of funding (for example, charitable funding, clinical fellows or applicants with funding from a foreign government or equivalent). Prospective applicants are strongly advised to contact their prospective supervisor in advance of making an application.

Please note that any applications received after the main funding deadline will not be assessed until all applications that were received by the deadline have been processed. This may affect supervisor availability.
