Jishnu Thekkeppattu recently joined CSIRO Space and Astronomy at Marsfield as a CERC Fellow. Jishnu earned his PhD in experimental low frequency cosmology from Curtin University. His thesis work was global 21-cm signal detection using single element radiometers and short-spacing interferometers. Prior to this, he worked as a Research Associate/Research Scientist at the Raman Research Institute in Bengaluru, India. After his PhD, he completed his first postdoctoral fellowship at Curtin University, working with SKA-Low prototype stations EDA2 and AAVS2. His work during this period includes unification of different holographic calibration techniques for phased arrays, as well as developing techniques for joint m-mode map making with the EDA2 and Onsala LOFAR station. As a CERC Fellow, Jishnu is excited to develop ultrafast imaging techniques using the EPIC framework, enabled by the latest generation Alveo FPGA accelerator cards. His research interests span a range of topics including experimental cosmology, radio astronomy techniques, interferometry, signal processing, and the ionosphere. He is also an active radio amateur, holding call-signs VU3VWB and VK6JN.
