I study the accretion flow properties of blackhole X-ray binaries during their outburst evolution through spectro-temporal analysis of their broadband X-ray observation. I am also interested in the interplay between the broadband electromagnetic radiation emitted from the different regions in the immediate vicinity of active galactic nuclei and how they can be used to constrain the physical properties of these systems.
Dr. Peter Boorman (he/him)
Postdoctoral Research Associate
I study the structure and evolution of the environment surrounding growing supermassive black holes with broadband X-ray spectral analysis and multi-wavelength observations. This includes finding and classifying black holes that grow behind thick layers of obscuring material, as well as analysing the growth of black holes across a broad range of mass, luminosity and accretion rate. I'm also interested in new ways to analyse astrophysical data including parameter exploration and data visualisation.

I study neutron stars using multi-wavelength observations to understand their evolution and interactions with other stars in compact binaries.
Dr. Margaret Lazzarini (she/her)
Postdoctoral Research Associate
I am a National Science Foundation Astronomy & Astrophysics Postdoctoral Fellow in the NuSTAR group at Caltech. I use multiwavelength observations of high mass X-ray binaries in nearby galaxies to constrain theoretical models of massive binary stellar evolution.
Dr. Labani Mallick (she/her)
Postdoctoral Research Associate
My research focuses on intermediate-mass and supermassive black holes that accrete matter from their host galaxies. I primarily study the X-rays emitted from the innermost region of the accretion flow. I develop and apply novel spectral-timing models and methods to black hole observations to extend our census of known parameters into the domains key to the black hole-galaxy co-evolution.

My research is on black hole accretion, with a particular focus on reflection modelling and spectral-timing analysis. Here at Caltech I am working on the development of new XILLVER reflection models, including adding polarisation information.
Dr. Joanna Piotrowska
Postdoctoral Research Associate
Coming from a PhD background in galaxy evolution in optical observations and cosmological simulations, I joined Caltech to study the central engines in massive galaxies - their Active Galactic Nuclei in X-ray, optical and UV wavelengths. In my research I combine conventional statistical methods with machine learning to extract information otherwise not captured from the data with standard analysis techniques.
Apart from galaxies and supermassive black holes I am also interested in the development of numerical methods, in particular (pseudo-) spectral schemes applied to discontinuous problems, e.g. shock discontinuities in fluids..
