It is the start of Autumn and that means the start of another new term. I’m now in my 3rd year of my PhD so right about now I should start getting good at this. The new term has brought a shift in my responsibilities, with the start of a number of new students in my lab following me being alone most of the last year. Apparently I am a senior member in my research group now. This means I am getting asked questions by experienced students, with me playing the role of someone who knows what they are doing.

I will say the introduction of students back to campus has been incredibly refreshing. Seeing undergrads going about their days has given me a lot more energy and drive to stay on campus and do work. I don’t think I truly appreciated how having a busy environment to work amongst results in a large increase in my productivity.

I haven’t written a blog post in a while due to various commitments and the constant wrestle with self-implosion over the summer. I took a side hustle doing freelance writing and wanted to focus on not completely failing at that. I had loads of ideas to write blog posts about not being able to re-do simple experiments, and the experience of finding out someone published the exact work you have already done. Hopefully I’ll find some inspiration to write about those in the future.


When I get asked the inevitable question of ‘what do you do?’, I always struggle to give a good answer. My work is slightly confusing, I am a Chemistry student, who is funded by Geosciences, and spends the majority of my time in Biology buildings. In addition, I am situated in the Organic Chemistry section of the Chemistry department, but do work closer to Inorganic Materials Chemistry. If I don’t understand what world I fit in to, how can I ever explain what I do to anyone in a way that’s understandable?

I would love to say I like being asked ‘What do you do?’, but that would be a lie. I’m sure this isn’t unique to doing a PhD though. What I normally tell people is that I study algae. Then I say I study the mechanism of biologically controlled crystallization in a species of algae that live in the ocean. When people say ‘what does that mean’, my response is something along the lines of ‘well, living things produce materials and they are very well suited to carry out a specific task. So if we can study and understand what they do, then we can use these techniques in other areas’. People normally give up after that, I think that means I should probably work on my communication skills.

Obviously, this is an overview of my work, it’s not actually what I do on a day-to-day basis. A better way to describe my PhD, a more authentic explanation, is that I grow small algae cells, experiment on the cells, and then look at them under a microscope. That makes it seem much simpler. In all fairness, it completely removes all context of why I’m doing what I’m doing, which is what is interesting. Maybe that’s why I don’t give it as an explanation when I get asked the question.

Microscopy is interesting. You can see super small objects in detail. What’s not to like about that? For reference, when I say small, I mean micrometres. The cells I study are between 1 and 10 micrometres. The average diameter of a human hair is 50 micrometres. Microscopy is not only limited to what’s happening on the outside of cells. You can also observe what is going on inside a cell, by splitting it open or adding a chemical that will colour the objects inside the cell. So to go slightly further with the simplified definition of my PhD, I can use these principles of microscopy to understand what these algae cells are doing, and how they produce the complex materials which I am interested in.

Spending all my time doing microscopy does mean making a sacrifice though. I need to do everything in darkness. This means I spend the majority of my time either sat in dark rooms or rooms lit by artificial lighting. To further compound me to never seeing sunlight, my office is situated in a small room with small windows, which seem to be afraid of the sun. This may sound bleak, but actually, sitting in a dark room for hours on end, looking at weird environments unimaginable to the human eye, allows for complete seclusion from the outside world. The time just flies by. So I am more than happy to sit in a windowless room most of the day, the name for this blog wasn’t chosen at random after all.

I decided to study Chemistry at university for two reasons. One, I wanted to have a successful career where I got payed well, and two, because I wanted to save the world. When you are a 17 year old kid who doesn’t know anything and is easily influenced, this means you have to do Science. And because of my interest in the natural world (and to a lesser extent my hero complex), it did not take long to realise the best option would be to become an environmental scientist.

When it reached the inevitable stage of my life where I had to start thinking about a career, I did not hesitate in choosing Chemistry. So I picked the best universities that were not Oxford or Cambridge (not because I didn’t think they were good universities, I just didn’t think I was clever enough to get in!), and chose the place I liked best on the open day. That is how I found myself doing a Masters degree at Bristol University.

What followed in my four years at Bristol was a deep relief that I had chosen the right course and university. After muddling through the first 2 years, when most people went off to do a year in industry or a year abroad in the 3rd year, I stayed in Bristol. Although I didn’t get to go and party in America for a year, this eventually turned out for the best, as I spent the year doing lots of lab work and research. It was during this time I had the realisation I enjoyed research more than anything else.

When it came time to pick a graduate career (the most stressful time of my life for sure), I knew I had to do a PhD. I didn’t care what I would eventually do, I just knew that the next logical step for me was a PhD. I wasn’t particularly interested in any Chemistry research that I had come across during my undergrad, so due to my dream of working in environmental studies, I started looking for projects in the area where I could use my Chemistry experience. Fortunately, Edinburgh decided this was good enough and offered me a PhD position.

I study the mechanism of biologically controlled crystallization in a species of marine phytoplankton (phyto=plant, so they photosynthesise basically) called coccolithophores. You have definitely heard of them, materials they produce accumulate together under pressure to produce the Great Cliffs of Dover. You can also see great blooms of them on nature documentaries, with David Attenborough saying “these are the unsung heroes of our planet” or something like that. They are pretty important in studying how biology produces different materials, and they play a role in key environmental processes as well.

Although I haven’t become an environmental scientist (I did get quite close though), I think it’s for the best as I wasn’t ready to give up Chemistry. I get to spend a lot of time in the lab and use expensive equipment to look inside cells and analyse what I see. Plus, the ability to control if millions of cells live or die make me feel like an omnipresent ruler.
