My Profile Photo

James Clark Ross

I am a PhD candidate in philosophy at the University of Southampton, researching the role of ‘grounding’ in explanation.
I am also the founder of The Human Front, a philosophy website covering topics in art, existentialism, film, metaphysics, science, and society.
And I am a
nuclear medicine physicist for the National Health Service (NHS).

Thanks for stopping by!



I am studying for a PhD at the University of Southampton. Currently this is a part-time endeavour which I perform in complete parallel to my professional work as a nuclear medicine physicist, for which I’m based in London.

In philosophy I am interested in ontology—specifically, in the hierarchy of reality through ‘grounding’.

Under the supervision of Naomi Thompson, I am investigating what makes it the case that causal relations, relevant to scientific explanations, obtain in virtue of grounding. In particular, I am interested in connections between causation, non-causal dependence relations like grounding, and metaphysical explanation. I hope to contextualise the conclusions I draw in my PhD project to scientific methodology by developing a single schema of explanation which subsumes grounding and causation using one set of principles, treating science and metaphysics as continuous.

Prior to studying for my PhD I obtained a master’s degree in philosophy (MA) at Birkbeck, University of London, graduating in 2020 with a distinction. My dissertation was titled ‘Top-Down Causation in the Animal Kingdom’ and completed under the supervision of Ben Springett.

Nuclear Medicine

I am an experienced nuclear medicine physicist who has worked in number of the UK’s leading hospitals. As a clinically registered professional, I am proficient with a multitude of equipment and software common in nuclear medicine and radiology departments. I have also published numerous clinical-research papers, many of which as leading author, and I am skilled in both clinical and research environments. I have spoken and been chair at national conferences.

My chief aim is to make a positive difference to people’s lives, while I relish the opportunity to train the next generation of clinical physicists.

I have degrees in physics, MPhys (Hons), from the University of Manchester, and medical physics, MSc (Dist.), from the University of Liverpool.

The Human Front

The Human Front is an evolving project which embodies my overflowing interests in philosophy. The project is made possible by a team and our wonderful contributors. Common themes include truth, meaning, existence, freedom, justice, the Absurd, and identity. How questions are interpreted is left with the reader. In an attempt to make sense of them in my own writings, I reach out to illustrious fiction and film, and, of course, my own beliefs.


This website showcases the biggest projects of my professional life: philosophy and science. I am a scientist-turned-philosopher with teaching experience in physics and mathematics. But my passions do not stop there.

I have a deep love of film, I listen to a lot of music, and I watch and play football quite seriously (perhaps too seriously).

Anyway, I hope you are able to find what you are looking for on my website! If not, you can always contact me via email, Twitter, or LinkedIn.
