Dr Stephen R. Taylor

I grew up in a small village called Glenavy in Northern Ireland, before reading Physics at Oxford University. After achieving my MPhys there, I was awarded a UK Science & Technology Facilities Council studentship to study for my PhD at the Institute of Astronomy, University of Cambridge. During my graduate studies, I focused on new inference techniques for near-future gravitational-wave (GW) observations. In particular, I developed a technique to constrain cosmological parameters using only GWs, which will be a leap forward from other techniques requiring a combination of GW and electromagnetic data. More recently I have become interested in the GW astrophysics possibilities with pulsar-timing arrays. Dedicated high-precision timing of an ensemble of millisecond pulsars will allow measurement of transiting GWs, which cause a perturbation to the pulse arrival times. My work involves developing new techniques to map the properties of the nanoHertz GW sky, which may have a superposition of supermassive black-hole binary systems as its source, or something more exotic, like a decaying cosmic-string network.

In my free time I can be found reading spy or historical novels, lounging in a movie theatre, or hanging out with friends and family.
