1. Tell us something about yourself.
I'm a radio astronomer currently employed as a research assistant at the Netherlands Institute for Radio Astronomy (ASTRON). I studied physics at the University of Manchester, then completed a PhD at Jodrell Bank Observatory before moving to Perth, Western Australia, to take up a postdoc fellowship at Curtin University.
As is the case with many astronomers, my fascination with the stars started at a young age and I joined my local astronomical society at the age of ten. Probably because of this, my research interests are somewhat broad and I will happily study anything that looks interesting - the universe is just so big and full of cool stuff! Mainly I study galaxies, usually those with high rates of star formation, but I am interested in supernovae, masers, active galactic nuclei, ultra-luminous X-ray sources and gravitational lensing, as well as exploiting new techniques such as wide-field VLBI. While I spend most of my time using radio interferometers, I often dabble in other wavelengths.
Over the years I have done a lot of public outreach, and since 2006 I have been part of the Jodcast, a podcast produced by students and postdocs based (mainly) at Jodrell Bank Observatory. I am also an occasional contributor to Astronomy.FM
2. Which telescopes/instruments do you use?
Most of my professional life involves using radio interferometers such as the newly-commissioned e-MERLIN, the European VLBI Network, the Very Long Baseline Array in the US, the Long Baseline Array in Australia, and the Westerbork array here in the Netherlands. This technique of linking together telescopes can provide some of the sharpest possible pictures of our universe.
I am also currently involved in an exciting project which will combine data from the VLBA with simultaneous observations with the Chandra satellite and the soon-to-be-launched NuSTAR mission.
At home, I still have my first telescope: a 2.5-inch Russian Tal that I've had since I was seven. The optics are shocking, and it looks more like a miniature rocket launcher than a telescope, but it can still give a pretty good view of a few things. My other telescope is a small brass nautical telescope made in the 19th century which my Dad gave to me. It's not much use scientifically, but it is a beautifully made instrument.
3. What are the computers and other hardware you use for personal and professional work?
On my desk I have a small Lenovo Thinkpad which I mainly use for writing papers and connecting to servers around the building to do my data analysis since, a lot of the time, I deal with large datasets which would never fit on my laptop's hard drive.
I still use the Texas Instruments calculator I've had since high school.
For podcasting and radio work I use an Edirol R09 recorder together with a CS-15 microphone and a mic stand from Ashton.
Much to the amusement of my colleagues, I also have an eclectic collection of inflatable planets, a model solar system on a string, a toy alien, a 5-foot rocket, and various other strange things for doing talks to kids of all ages.
I'm usually found listening to music; at work I use an ipod, at home I have a hifi.
When I'm not working I enjoy playing music too. I played drums in a Samba band when I lived in Australia, and at the moment I play guitar (a gorgeous cherry red SG) with some friends here in the Netherlands.
4. What are the software tools that you use on a day-to-day basis?
I use Linux for almost everything. My first computer ran Linux and I quickly discovered that I enjoy tinkering too much to ever make the switch to Windows or Mac. This turned out to be quite useful when I got to university since most of the software written for astronomy runs on *nix systems.
For data analysis I mainly use AIPS and, occasionally, CASA. I also regularly make use of TopCat and Aladin, often together, especially when working on wide-field projects with hundreds of sources in one field.
I often keep in touch with collaborators around the world (and in the building) via Skype.
For writing papers and notes (and *shudder* editing postscript files) I use nano, vim or emacs, although I still find post-it notes invaluable for keeping my projects organised - my office wall is something of a visual to-do list of pictures, plots and post-it notes. My papers and observing proposals are all formatted with LaTeX.
All of my audio projects are edited and post-processed in Audacity.
5. What programming languages do you use?
As an undergraduate I learned to program in C, but later discovered Perl and it became my default language during my PhD because I found it much faster for quick hacks.
Last summer, while helping with the commissioning of e-MERLIN, I discovered Python and learned to use ParselTongue in order to script much of the process of data analysis from the new correlator. Scripting AIPS can be painful at times, but ParselTongue/Python makes it almost pleasant.
6. What would be your dream hardware and software setup? What would be your dream telescope/instrument?
Well, aside from a relativity-defying spaceship so I could actually go and see what's going on inside messy, dusty starburst galaxies with my own eyes and still be back in time for tea.... there are so many exciting new facilities in development right now.
Being mainly a radio astronomer, I am of course really looking forward to the SKA and its precursors: ASKAP and MeerKAT. The various science questions which these telescopes are being designed to answer are really important ones, but what is the most exciting prospect to me (as with any new telescope) is the discovery of the unknown - those objects that we have no idea are even there right now because our current telescopes are just not sensitive enough to detect them.
