I work to make software development easier and more accessible so that every programmer can easily write, maintain and optimise software. I maintain a list of must-read research papers for machine learning in compilers. My research interests include:

• Program optimisation and analysis: I am interested in how we can design new algorithms and optimisation techniques at compilers and operating systems to improve application performance and energy efficiency.
• Software testing and software reliability: I use machine learning and code analysis techniques to detect software bugs and to improve software reliability; Our recent work has identified 200+ bugs from real-life projects.
• Accelerate large-scale deep learning models: I work to make the training and use of large-scale deep learning models accessible to every data scientist by collaborating with major industrial players including Meta.
• Applied machine learning: Some of my works apply machine learning to emerging applications areas like natural language processing, data mining and wireless sensing.

PhD students: Scholarships are available for outstanding candidates. Being an advisor to students is the best part of my job. Have a look at my research interests and recent publications. If any of those grab you, send me an email with a CV and a short text describing your background. I am also open-minded - if you have a great idea you would like to pursue - get in touch! Please read here before applying.

I am a (full) professor and a member of the Distributed Systems and Services Group at Leeds, the EPSRC Peer Review College, the UKRI Talent Peer Review College (PRC), and the HiPEAC Network of Excellence. I was a Turing Fellow at The Alan Turing Institute. I was named among the Elsevier and Stanford World’s Top 2% Scientists in 2020, 2021, 2022 and 2023. I am a recipient of the Test-of-time Award in CGO 2024, Best Paper Award in ACM PACT 2010 and 2017, ACM CGO 2017 and 2019, Best Presentation Award at PACT 2010 and CGO 2013, 4 HiPEAC paper awards, and Best Paper Nomination/Finalist in ACM SC 2024, ACM SenSys 2019, and ACM CCS 2018. I am in the unofficial CGO hall of fame. I have an Erdős Number and a Dijkstra number of four.

• [March, 2024] Received CGO 2024 Test-of-time Award for my CGO’13 paper; selected as a paper that was published 10 – 12 years prior and has had a lasting impact on the field.
• [September, 2023] New 24-month Innovative UK project awarded (PI) - An RA post will open soon.
