Gambling with Statistics – Monte Carlo Methods

July 20, 2013

Hey all! In my recent work I’ve been using numerical simulations involving radiative transfer, which basically  means transferring energy via radiation such as light; in the form of photon packets. The way these simulations are run is via a method known quite widely in the physics world called ‘Monte Carlo Methods’. It took me a...

Research Talks

December 16, 2019

Included here are a selection of my upcoming and recent research talks. 12th October 2018 – Gaia DR2 Specialist Discussion Meeting at the RAS I had the privilege of being included in the talks for the specialist discussion meeting sharing the scientific insights gleaned from Gaia DR2. At this meeting I presented a talk about...

Outreach Talks

Upcoming Talks No upcoming outreach talks planned at the moment. Past Talks 18th July 2019 – Kernow Astronomers I joined Kernow Astronomers on Thursday 19th July for a talk about interstellar dust. We explored the origins of dust, how it evolves and forms into planets and how it effects us in our everyday lives. 27th...

Chirp – An App for Monitoring Gravitational Wave Alerts

November 1, 2019

I’m absolutely delighted to announce that a spare-time project I have been involved with for the best part of a year has finally been released. Enter Chirp – an app to help you monitor gravitational wave alerts. The app is being officially released to coincide with the start of O3b, the second part of the...

Talking ‘Big Data in Astronomy’ with Digital Taunton

July 13, 2019

On 27th June I got the pleasure of going to Taunton to do a talk about the crossover between technology and astronomy at the 5th Digital Taunton meetup. The natural topic is of course the way modern astronomy has embraced the use of ‘big data’ datasets and techniques. When I first put the fledgling version...

We Discovered an FUor

December 20, 2018

We discovered a very rare kind of star – in fact there are only 25 stars of its type known to exist. The fact that we found it is amazing, but the way we found it was even more interesting. We caught it red handed during an FUor outburst – a period of intense flaring...

About Me

August 12, 2018

I am an astrophysicist, currently working in the astrophysics group at the University of Exeter. Under the supervision of Professor Tim Naylor, my PhD project involves understanding the evolution and characteristics of M-dwarfs. By harnessing the power of the second data release of the Gaia mission, we have been able to develop methodology for measuring...

Web Development for Physicists

February 17, 2018

I’m fortunate enough to be sitting at the intersection of two disparate fields which are rapidly hurtling towards each other. More than ever, it’s becoming important to publicise you and your research, whether you’re in academia or in the private sector. Sooner or later, this is likely going to mean you’re going to requiring some...

XRT-C Dish Mounting Video is Finally Here!

February 8, 2018

This one has been a long time coming. The XRT-C project has likely seemed a little bit quiet of late, but never fear, as there’s always stuff going on in the background, even if it is only me. Ever since the build day in April 2016, I’ve been working on a video of the day...

YouTube
