Neena J Mani obtained her PhD in Atmospheric Science in 2012 from the Indian Institute of Tropical Meteorology, Pune. She was a postdoctoral fellow jointly at Jet Propulsion Laboratory, California Institute of Technology and University of California Los Angeles  before joining IISER Pune in 2015.



Neena’s main research interest lies in understanding the large scale drivers and teleconnection mechanisms which control the short and long timescale variability of the Indian summer monsoon (ISM). Her group investigates instrumental and paleoclimate records and tries to understand the teleconnection mechanisms using hierarchy of climate models in the context of present and past climate scenarios. This will provide crucial information on how the future monsoon may get modulated in response to the changes in the global climate modes. Her other research interest lies in understanding the theoretical and practical predictability of different scales of atmospheric variability. Some of her significant research contributions include : (a) Identification of a lowering of monsoon weather predictability in a warming world (b) quantification of the predictability of Tropical Intraseasonal Oscillations (ISO) in contemporary climate models (c) developing model performance metrics for the ISO d) developing a mechanistic understanding of the El Nino - monsoon teleconnection.
