Academic staff

    • Dr Philippe Blondel
      Deputy Director of the Centre for Space, Atmosphere and Ocean Science.
      I am developing new approaches to remote sensing, in particular acoustics, radar and satellite imaging. I also work on processing very large data-sets using machine learning and image processing. This ties in with my work studying asteroids and has intersections with the space mining communities, and radar imaging of space debris.

    • Dr Steven Davies
      I am involved in the design and construction of front-end instrumentation for millimetre-wave molecular line astronomy. I am also interested in the use of microfabrication and micromachining methods to make high frequency devices and the circuits in which they are mounted.

    • Dr Victoria Scowcroft
      I use multi-wavelength observations of variable stars to make high precision distance measurements. My current research focuses on mid-infrared observations of Cepheids and RR Lyrae variables, incorporating data from the Gaia mission, to calibrate their Period-Luminosity relations with the aim of improving the extragalactic distance scale. My research group studies the structure of the Milky Way and the Magellanic System to measure the Hubble constant with mid-infrared standard candles to a precision better than 2%.

    • Dr Patricia Schady
      I study multi-wavelength observations of long gamma ray bursts and use them to study the interstellar medium and star-formation in distant galaxies. I am also interested in other kinds of stellar transient phenomena, such as super luminous supernovae and kilonovae, and on the evolution of galaxies and their chemical enrichment.

    • Dr David Tsang
      I study the relativistic astrophysics of neutron stars and black holes. I am interested in neutron binary systems as sources of possible electromagnetic counterparts to gravitational wave signals, and as a probe of physics within the neutron star crust. I also study the formation and evolution of planetary systems, in particular looking how dynamical processes and interactions could explain emerging features of the exoplanet population.​

    • Dr Hendrik Van Eerten
      I carry out computational and theoretical research in high-energy astrophysics. My primary focus is on the relativistic outflows and afterglows from gamma-ray bursts, and blazars.

    • Dr Carolin Villforth
      I study Active Galactic Nuclei (AGN) - accreting supermassive black holes at the centres of galaxies. I am interested in understanding the processes that fuel supermassive black holes, the physical properties of AGN as well as the impact AGN have on their host galaxies.

    • Professor Stijn Wuyts
      I study the formation and evolution of galaxies, from the peak of cosmic star formation ten billion years ago to the present day. To this end, I combine tracers of direct star light, dust-radiated emission, ionized and molecular gas. Together, they shed light on the growth of galactic disks, the emergence of bulges, and the connection to the dark matter halos in which galaxies reside.

Postdoctoral associates

    • Duncan Neill (Supervisor: Dr David Tsang)
      Multi-messenger probes of neutron stars
      I am working on calculating the frequencies of modes of oscillation in neutron stars. In particular I am interested in the interface modes between the star's solid crust and fluid core. The aim is to study how resonance between these modes and tidal forces can cause the crust of the neutron star to fracture, causing a gamma-ray burst.

PhD students

    • Mathilda Avirett-Mackenzie (Supervisor: Dr Carolin Villforth)
      The role of mergers and disc instabilities in fuelling AGN
      I study the mechanisms that trigger enhanced accretion onto galactic supermassive black holes. I use machine learning to look for galaxy mergers with the goal of understanding their role compared to internal processes in fuelling different types of active galactic nuclei.

    • Blanca Moncada Cuadri (Supervisor: Prof Carole Mundell)
      Tidal Dwarf Galaxies as Laboratories for Understanding the Origins of Star Formation.
      I am using cm and mm radio observations of Tidal Dwarf Galaxies to trace their history of star formation and determine the distribution and polarization of the radio emission, to map their magnetic field. The aim is to study the physics of star formation in extreme environments so we can understand how stars formed in the early Universe.

    • Bethan Easeman (Supervisor: Dr Patricia Schady)
      Investigating the build-up of metals in star forming galaxies
      I study the chemical composition of galaxies, in particular investigating how the distribution of heavy elements relates to the galaxy star formation and accretion history. The metallicity of a galaxy can be traced in a variety of ways, and the aim of my work is to understand how different tracers affect our understanding of the cosmic chemical evolution of galaxies.

    • Shaula Garibbo (Supervisor: Dr Philippe Blondel)
      Low-Frequency Ocean Acoustic Phenomena
      I study the variability and mechanisms of acoustic waves through the Earth’s oceans, particularly the low-frequency waves that can propagate at planetary scales across a wide range of environments. I am using Big Data and sophisticated processing approaches, with the aim to develop operational models to monitor large transient events (e.g. explosions, geophysical events) and long-term trends.

    • John Hope (Supervisor: Dr Hendrik van Eerten)
      I use a combination of hydrodynamical and kinetic simulations to model the afterglow of structured jets in Gamma-Ray Bursts. These models are then compared to observational data to better understand the processes that are taking place in these jets.

    • Raman Sharma (Supervisor: Dr Stijn Wuyts)
      Star formation distributions across cosmic time
      I am using a combination of simulations and multi-wavelength observations of galaxies at different lookback times to quantify their star formation distributions and stellar population content on a spatially resolved level. I intend to use these diagnostics as inference to assess the physical mechanisms that lead to morphological transformations within galaxies, tracing progenitors and descendants across cosmic time.

    • Junkai Zhang (Supervisor: Dr Stijn Wuyts)
      The relation between galaxy structure, kinematics and environment
      Using deep lookback surveys I study galactic structure and how it depends on the environment in which galaxies live. I am inferring intrinsic 3D shapes from the projected axis ratio distributions of ensembles of galaxies, and will tie in dynamical measurements to further understand their structural evolution.

    • Dr Tanmoy Laskar
      I study energetic transient events such as supernovae and gamma-ray bursts. I use observations across the electromagnetic spectrum and theoretical modelling to investigate the progenitors and host galaxy environment. I carry out research ranging from the fundamental physics of astrophysical shocks to cosmology through the search for transients from the first stars and galaxies.​
