Research Outline

MRes Astrophysical Chemistry

My intention is to research the cool circumstellar environments of stars and probe their chemical makeup. The research will primarily involve pre-main sequence (Herbig Ae/Be) stars and an exploration of the morphology, evolution and composition of their accretion disks/haloes. Of particular interest are young stars such as Elias 1, which bear signatures of unusual carbon compounds including polycyclic aromatic hydrocarbons and nanodiamond dust grains. Their formation mechanisms are not yet fully understood.

With the ongoing recent discoveries of ever increasing numbers of extrasolar planets, it is becoming clear that our understanding of the principles of planetary formation and evolution of stellar systems is incomplete at best. Therefore, using a combination of spectroscopic and astronomical imaging techniques, I intend to work towards the characterisation of these environments, draw inferences and postulate any implications on the unresolved phenomenon of planetary formation.



Personal Statement

My interest in astronomical sciences is an ongoing one, with my earliest interests lying in stellar and planetary astronomy. This interest has been further compounded during my undergraduate studies into exotic chemistry (such as that of the interstellar medium) and the organic chemistry of aromatic compounds such as those detected commonly in many circumstellar and interstellar environments. Further to this, my most recent interests through my own personal studies are in cosmology and astrobiology.

During my time working in the graphic design industry I have become proficient in visualisation and image enhancement techniques, which I believe will be of great help in astronomical imaging applications. Aside to this, it has also made me an excellent communicator, able to visualise ideas and present information in a way which both emphasises key points and is conductive to the comprehension of the target audience.

I am applying to study at postgraduate level primarily to learn more about the subjects that interest me. I believe that through a combination of my acquired skills and knowledge and that which I am capable of learning, I can make a significant contribution to the field of astrochemistry. Finally, I enjoy research and I would like to pursue a scientific career.
