One of the great things about being a Research Software Engineer is the diversity of work you can get involved with. I specialise in smaller interventions which means that I can be working with physicists on Monday, engineers on Tuesday, geneticists on Wednesday….you get the idea.

Last month, I got to work with some Ecologists along with Anna Krystalli. We undertook the arduous journey from Sheffield down to Exeter to deliver talks and workshops at a post-conference symposium on reproducibility in science, organised by Malika Ihle and Isabel Winney, at the International Symposium on Behavioural Ecology.

I gave my talk, Is your research software correct?, and also delivered a workshop on using projects and version control using R and RStudio in the Code Cafe style. For the full write up of the day, see the excellent blog post by Anna over at the Mozilla Science Lab blog.

Back in December 2014, I learned that I’d be moving from The University of Manchester to The University of Sheffield to do the type of thing I’ve always done which is a combination of research software engineering and research software support.

I’ve been in Sheffield for two months now and am having a blast! There’s so much cool stuff going on here that it makes my head spin a little and the community at Sheffield have welcomed me with open arms. It truly is a wonderful place in which to work.

One of the departments I’ve started working with is The Sheffield Institute for Translation Neuroscience (SITraN). My contributions have been relatively minor so far – A bit of Python coding for a machine learning project called GPy and some code speed-up work in R for Winston Hide and his collaborators. When I hang out in SITraN, I usually sit with the machine learning people and listen in on their conversions about Python, MATLAB, GPUs, C++ and R — it’s essentially Nerdvana for someone like me.

On to the point of this blog post. SITraN now have their own blog called SITraNsmissions where they’ll be discussing various aspects of their work and how it applies the principles of neuroscience to help treat diseases such as Motor Neurone Disease (MND). In the video below, taken from SITraNsmissions first blog post, Professor Pamela Shaw gives an overview of the work that SITraN does.

Research Software Engineers (RSEs) are the people who develop software in academia: the ones who write code, but not papers. The Software Sustainability Institute (a group of which I am a Fellow) believes that Research Software Engineers lack the recognition and reward they deserve for their contribution to research. A campaign website – with more information – launched last week:

http://www.rse.ac.uk

The campaign has had some early successes and has been generating publicity for the cause, but nothing will change unless the Institute can show that a significant number of Research Software Engineers exist.

Hence this post. If you agree with the issues and objectives on the website, please sign up to the mailing list. If you know of any other Research Software Engineers, please pass this post onto them.

One of my favourite parts of my job at The University of Manchester is the code optimisation service that my team provides to researchers there.  We take code written in languages such as  MATLAB, Python, Mathematica and R and attempt (usually successfully) to make them go faster.  It’s sort of a cross between training and consultancy, is a lot of fun and we can help a relatively large number of people in a short time.  It also turns out to be very useful to the researchers as some of my recent testimonials demonstrate.

Other researchers,however, need something more.  They already have a nice piece of code with several users and a selection of papers.  They also have a bucket-load of ideas about how to  turn this nice code into something amazing.  They have all this good stuff and yet they find that they are struggling to get their code to the next level.  What these people need is some quality time with a team of research software engineers.

Enter the Software Sustainability Institute (SSI), an organisation that I have been fortunate enough to have a fellowship with throughout 2013.  These guys are software-development ninjas, have extensive experience with working with academic researchers and, right now, they have an open call for projects.  It’s free to apply and, if your application is successful, all of their services will be provided for free.  If you’d like an idea of the sort of projects they work on, take a look at the extensive list of past projects.

So, if you are a UK-based researcher who has a software problem, and no one else can help, maybe you can hire* the SSI team.

I am extremely short sighted and have a contact lens prescription of the order of -10 dioptres or so.  Recently, I was trying to explain to my wife exactly how I see the world when I am not wearing my contact lenses or glasses and the best I could do was ‘VERY blurry!’

This got me thinking.  Would it be possible to code something up that took an input picture and a distance from my eyes and return an image that would show how it looks to my unaided eyes?

Would anyone like to give this a go?  How hard could it be?

One of my academic colleagues, Fumie Costen, recently asked members of The University of Manchester GPU Club the following question

‘I am looking for a journal with high impact factor where I can publish our work on GPU for FDTD computations.  Can anyone help?’

So far, we haven’t had any replies so I’m throwing the question open to the world.  Any suggestions?

Earlier this year I was awarded a fellowship from the software sustainability institute, an organization that works to improve all aspects of research software.  During their recent collaborations workshop in Oxford, it occurred to me that I was aware of only a relatively tiny number of software projects at my own institution, The University of Manchester. I decided to change that and started contacting our researchers to see what software they had released freely to the world as part of their research activities.

Research software comes in many forms; from small but useful MATLAB, Python or R scripts with just a handful of users and one developer right through to fully-fledged applications used by large communities of researchers and supported by teams of specialist developers.  I’m interested in knowing about all of it.  After all, we live in a time when even a mistake in an Excel spreadsheet can change the world.

The list below is what’s been sent to me so far and is a mirror of an internal list that’s been doing the rounds at Manchester.  I’ll update it as more information becomes available.  If you are at Manchester and know of a project that I’ve missed, feel free to contact me.

One of the benefits of working at a university is that you are surrounded by a lot of smart people doing very interesting things and it usually doesn’t take much effort to get them to talk about their research.  I work in the faculty of Engineering and Physical Sciences which means that I’m pretty well covered in subjects such as mathematics, physics, chemistry, engineering, computer science, materials and earth sciences but I have to go all the way to the other side of campus if I want to learn a little about the life sciences.

Last week, I attended a free event called The Rogue Cell which was arranged by The Wellcome Trust Centre for Cell-Matrix Research and hosted by  The Manchester Museum as part of World Cancer Day.  I had no idea what to expect out of the evening but if you were to press me I would have guessed that there was going to be a lot of power point slides and row upon row of gently dozing delegates.  I could not have been more wrong.

The event was arranged in a workshop format where all of the attendees were split into five groups of six or so.  Each group was then assigned a Wellcome Trust Researcher who’s job it was to explain to us one of five defining characteristics of a cancer cell which were

  • Evading the immune system
  • Angiogenesis (formation of blood vessels)
  • Migration/invasion
  • Proliferation
  • Lack of apoptosis (programmed cell death).

Each group kept their researcher for 20 minutes or so before they got assigned a new one who discussed a different topic from the five.  So, by the end of the evening we had covered the lot.  The presentations were intimate, informal and highly interactive and it felt to me like I was having a good chat down my local pub with a group of people who just happened to be world-class cancer researchers.  If only all learning experiences were like this one!

There was a great cross section of attendees from PhD biology students through to clinicians, undergraduates, random people off the street and, of course, the occasional math software geek.  One of the great things about this event was the fact that everyone seemed to get a lot out of it, no matter what their background.  I asked a lot of questions, many of which would have been blindingly obvious to a student of the life sciences but not once was I made to feel stupid or out of place.  It must have been exhausting for the presenters but I can honestly say that it was one of the most enjoyable learning experiences I’ve had for quite some time.

I sincerely hope that The Wellcome Trust Centre for Cell-Matrix Research and The Manchester Museum will be arranging more events like this in the future.

Back in the good old days when I was a freshly minted postgraduate student I had big plans– In short, I was going to change the world.  Along with a couple of my friends I was going to revolutionize the field I was working in, win the Nobel prize and transform the way science and mathematics is taught at University.  Fast forward four years and it pains me to say that my actual achievements fell rather short of these lofty ideals.  I considered myself lucky to simply pass my PhD and land a job that didn’t involve querying members of the public on their preferences regarding potato based products.  The four subjects of Laura Snyder’s latest book, The Philosophical Breakfast Club had broadly similar aims to my younger self but they actually delivered the goods and they did so in spades.

In this sweeping history of nineteenth century science, Snyder gives us not one biography but four — those of Charles Babbage, John Herschel, William Whewell and Richard Jones.  You may not have heard of all of them but I’d be surprised if you didn’t know of some of their work.  Between them they invented computing, modern economics, produced the most detailed astronomical maps of their age, co-invented photography, made important advances in tidology, invented the term scientist (among many other neologisms) and they are just the headliners!  Under-achievers they were not.

These four men met while studying at Cambridge University way back in 1812 where they held weekly meetings which they called The Philosophical Breakfast Club.  They took a look at how science was practiced in their day, found it wanting and decided to do something it.  Remarkably, they succeeded!

I found Snyder’s combination of biography, history and science to be utterly compelling…so much so that during my time reading it, my beloved iPad stayed at home, lonely and forgotten, while I undertook my daily commute.  This is no dry treatise on nineteenth century science; instead it is a living, breathing page-turner about a group of very colourful individuals who lived in a time where science was done rather differently from how it is practiced today.  This was a time where ‘computer’ meant ‘a person who was good at arithmetic’ and professors would share afternoon champagne with their students after giving them advice.  Who would have thought that a group of nineteenth century geeks could form the basis of one of the best books I’ve read all year?
