Dr. Sivakandan Mani is a Postdoc at the Radar Remote Sensing Department of the Leibniz Institute of Atmospheric Physics (IAP), Kühlungsborn, Germany. He received his M.Sc. in Physics (2011) from Presidency College, Chennai, India, and his Ph.D. in Physics (2018) from Andhra University, India, with research conducted at the National Atmospheric Research Laboratory, Gadanki.

His research focuses on atmosphere–ionosphere coupling, mesospheric and lower thermospheric (MLT) dynamics, and long-term variability of the upper atmosphere using radar, airglow, GNSS-TEC, and satellite observations. He has contributed to understanding gravity-wave-driven ionospheric irregularities, sporadic-E and E–F region coupling, and the penetration of midlatitude disturbances into low latitudes. He has also led long-term studies revealing interannual oscillations and trends in the mesosphere and ionosphere from multi-decadal datasets.

He has held research positions in India, Japan, and Germany, including at PRL, Nagoya University, the University of Rostock, and IAP, and was awarded the Alexander von Humboldt Postdoctoral Fellowship (2020–2022). He is currently the coordinator of LoLa, which focuses on investigating day-to-day variability in MLT–ionosphere coupling by resolving spatial and temporal ambiguities using coordinated multi-site radar observations.
