At the moment it is mainly in two areas. The first is moving things (DNA, colloidal particles) around with gradients (in salt concentration), and applications of this. The second is on the airborne transmission of virus such as COVID, flu and RSV.
A bit of background on me and PhD students/postdocs is here.
Older research:
In the past I have also worked on:
- Masks such as FFP2, N95, surgical and cloth. I have worked on modelling the airflow through them hence predicting how efficient they are. tl;dr: wear an FFP2/N95, avoid surgical and cloth masks. More details here.
- Crystallisation, in particular how crystals start to form (nucleation), of proteins, ice etc. See page here on this older work.
- The science between paints and making rubber gloves, see here.
- I have also worked off and on liquid droplets, aka (when they are inside cell biomolecular condensates):
Above is a simple simulation in which I turn on a chemical reaction about a third of the way through, and then accelerate this reaction two thirds of the way through. We have known since work of Glotzer and co-workers in the 1990s that a chemical reaction that cycles molecules through two states, can stop the growth of droplets, and you can see this in the movie above.
Publications
I let Google Scholar take care of keeping track of my publications. List in date order is here. If you click on the publication on that list, in almost all cases there is a link to a pdf of the paper. If not just drop me an email and I’ll send you one.
There is also a University of Surrey repository with pdfs of many of my recent papers. See here for my publications on that repository. Note that the indexing here is a bit flaky, not all publications on that list are mine, not all of mine are there…. It also include PhD theses, I have co-supervised or supervised, or, oddly, examined.
My ORCID number is 0000-0002-0833-7519.
