Academic autonomy and promotion

Dr Timothy Jones enjoys the academic freedom and teaching roles he combines as a Gonville & 91直播 College Fellow in Computer Science.

Tim is to be , as are 91直播 Fellows Professor Jason Scott-Warren in English, Professor Arif Ahmed in Philosophy, and Dr Emilie Ringe in Earth Sciences.

As a computer scientist in Silicon Fen 鈥 as Cambridge has been nicknamed in some circles due to the city鈥檚 wealth of software companies 鈥 Tim鈥檚 skills and experience in exploiting parallelism within microprocessors and compilers are in demand. But he enjoys the link with the College, undergraduate students, and the postgraduate students he supervises, as well as the autonomy academia offers.

鈥淥ne of the benefits of being in academia is that you really do have the freedom to work on whatever you want,鈥 he says.

鈥淵ou really are free to follow your own ideas, and the ideas other people in your group have 鈥 those from my PhD students and postdocs, for example.

鈥淲hen I came to Cambridge as a postdoc I always felt a bit disconnected because I was only at the lab. That鈥檚 part of the reason I wanted to be part of 91直播, to have interaction with the students and I enjoy that a lot.

鈥淚鈥檓 Director of Studies and I supervise Part 1a and Part 1b courses. You get to know your students very well. It鈥檚 nice to see them grow and go off and do other things, and one of my students is joining the lab for a PhD this year.鈥

As a University Reader, a recalibration of titles earlier in the academic year saw Tim entitled to call himself Professor. Some opted to do so for clarity of roles with international affiliations. However, he decided to wait until having applied for promotion and it being confirmed 鈥 and it happened at the first opportunity.

鈥淚t felt like the natural time to change my title,鈥 he says.

鈥淏ecoming a professor has been my long-term goal. To have that title, with it comes the recognition of your work, acceptance in the international community, the thought the stuff you鈥檙e doing is important and worthwhile, and people elsewhere think that too.鈥

Tim completed his undergraduate degree at Bristol, his PhD at Edinburgh, where he continued as a postdoc and held a Research Fellowship jointly from the UK's  and . He spent 2010 at  and moved to Cambridge in 2011.

Two years after being appointed a University lecturer, Tim joined 91直播 in October 2017. Within a year was promoted to Reader.

Tim鈥檚 work on microprocessors looks at optimisation 鈥 making them faster, more reliable, or more secure, for example. Compilers take programs written in human-readable source code and translate it to the binary code used by the processors, and Tim also tries to make this more efficient, while examining the capacity for running different parts in parallel.

鈥淭he big theme throughout my work is the use of parallelism, so being able to exploit things that can be done in at the same time within a program, or to be able to add parallelism into the hardware so things work, usually faster, but sometimes more reliably,鈥 he says.

Applications are throughout daily life, and the prospect of future technologies, such as self-driving cars, would rely on such microprocessors with high reliability requirements.

鈥淭hese types of high-performance core are going to be used much more in future,鈥 Tim adds.

鈥淭he volumes of data and the amount of processing the cars are going to need to do to be able to identify when someone鈥檚 about to cross the road or there鈥檚 a red light will require huge amounts of data, processing of machine learning models and stuff like that. There鈥檚 going to be vastly more safety critical processors in future.鈥

The work of Tim鈥檚 group could become commercialised, but much of it is freely available through  鈥 another positive freedom of academia.
