PhD reflections: Sorcha

Between a Rock and a Hard Place began as an Earth Science PhD blog in February 2013, as a place to ramble on about PhD life and general science topics. Almost two years later, some of the contributors have finished, others have submitted, and the rest are nearing the end.  Over the next few weeks, the BaR contributors will be sharing some reflections on their PhD experiences. Taken from an original post on the Bristol Doctoral College blog.

 

First up, the newly crowned Dr Sorcha McMahon!

 

PhD highlight:

Working in the lab was both the most exciting, and most frustrating, aspect of my PhD. Rather than jetting off to exotic field locations, I spent most of my days heading downstairs to the basement to carry out experiments on a piston cylinder apparatus to provide insights into deep mantle melting.

Despite shedding blood, sweat and tears down there, the satisfaction of deliberately ending a successful experiment is hard to beat! Lab work was made all the more fun when shared with fellow experimentalists – discussing similar experiences, particularly failures (unfortunately rather common!) proved to be incredibly useful in planning future experiments and trying different approaches to improve methods.

She is manually topping up the pressure (to 30 kbar, equivalent to ~100 km depth!) whilst checking the run temperature recorded by the thermocouple – lots of multitasking!

Top tip:

My top tip is to talk to lots of people in the lab, and attend lots of seminars/discussion groups, about different techniques that you could possibly try out on your samples. Most lab-based PhDs tend to be a case of trial-and-error for the appropriate method so the more options that you are aware of, the better!

I am investigating how carbonatites may form, using both natural rock and experimental approaches.
