My Top Tips for Preparing for a Physics Degree

August 10, 2015

You’ve just finished your A-levels, you say? Well done, I think you’ve earned a break so go on and enjoy it. However, I wouldn’t mind guessing that at some point in the next couple of months you’re going to get a little bit bored and might even start looking for something to do. If you’re kicking...

About Me OLD

May 26, 2015

I'm a postgraduate astrophysicist working in the astrophysics group at the University of Exeter. My PhD project, under the supervision of Professor Tim Naylor, involves studies of planet forming stars. In this project we hope to be able to observationally study the mechanisms of planet formation around young stars in an attempt to validate current theory. I also...

My Research

My research interests span a wide variety of topics. My masters research focussed on studies of extinction and interstellar dust. Throughout my PhD, my work focussed on observational studies of the evolution of stellar clusters, low-mass stars and characterisation of exoplanet host stars. These studies have made extensive use of cutting edge observational data from...

#InternationalWomensDay

March 8, 2015

You may have noticed that today, Sunday 8th March 2015, is International Womens Day. This sounded like an ideal time to write about some exceptional scientists whom I greatly admire; who just also so happen to be women. Rosalind Franklin The Woman Who Discovered the Structure of DNA The discovery of Deoxyribonucleic Acid (DNA) is the...

Modeling Atmospheres with the Unified Model

February 24, 2015

In my last couple of posts I’ve been going through some of the basic principles of fluid mechanics. From some of the basic approximations that make the equation possible to analytically solve in this post, to some more specialised theory in the context of planetary systems in this post. In these posts we’ve been slowly...

Some Fluid Mechanics Basics

January 23, 2015

At the moment I’m intently studying fluid mechanics for an exam on planetary science. As you may have guessed, the fluid mechanics in question is for modelling planetary atmospheres, but the mathematics is universally applicable. I’ve wanted to learn fluid mechanics for many years so I thought I’d just go through some of the basics...

Radiative Transfer in Planetary Atmospheres: An Overview

January 1, 2015

A little while ago I got carried away on a little post which discussed a really cool little bit of physics called radiative transfer. As I said then, radiative transfer is a technique that you can use to study how energy, in the form of electromagnetic radiation, moves through material. In that post, which you can...

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...
