A brief career sketch

2017 -          Director, Application Laboratory
2009 -          Adjunct Professor, OTPE, University of Tokyo
2019 -          Visiting Professor, NEKKEN, Nagasaki University
2019 -           Visiting Professor, CORAL, IIT Kharagpur
2009 - 2019 Visiting Professor, Sophia University
2014 - 2016: Group Leader, Climate Variability Prediction and Application Research Group, Application Laboratory, JAMSTEC
2013 - 2014: Program Director, Society-Oriented Prediction Engineering Science Program, Application Laboratory, JAMSTEC
2009 - 2012: Team leader, CVPARP, RIGC, JAMSTEC
This team has been developing the SINTEX-F coupled GCM under the EU-Japan collaborative framework. The prediction results are regularly updated and uploaded on the seasonal climate prediction website of JAMSTEC and used in outreach programs such as SATREPS projects southern African region.
2003 - 2008: Sub-leader, CVRP/FRCGC/JAMSTEC, Yokohama, Japan
Actively managed a project to develop the SINTEX-Frontier coupled GCM for climate studies. The SINTEX-F model has been used for climate prediction experiments on seasonal-to-decadal time-scales.
Actively participated in the outreach program called Kyosei initiated by the Ministry of Science and Technology, Culture and Sports of Japan for Sustainable Coexistence of Human, Nature and the Earth. Under this Kyosei project (K-5), a consortium comprised of University of Tokyo, FRCGC, Mitsubishi Heavy Industries, and several other universities undertake a pilot project to develop an oasis in the southwestern part of the Saudi Arabia. 
1998 - 2002: Researcher, FRSGC, Tokyo, Japan
Developed numerical ocean models to simulate interannual variability of the Indian Ocean. The numerical simulations are used to understand the ocean processes related to Indian Ocean Dipole and other modes of variabilities in the Indian Ocean. 
Carried out data analyses and climate diagnostics to discover the subtropical Indian Ocean dipole.
Studied the dynamical and thermodynamical processes of the upper Indian Ocean using simple ocean models.
1988 - 1997: Scientist, Indian Institute of Tropical Meteorology, Pune, India
Developed moderately complex reduced gravity numerical ocean models to understand upper layer circulation and SST variabilities in the tropical Indian Ocean.
Undertook ocean model experiments to understand the relative importance of remote and local forcing on the coastal circulation around India. Conducted numerical experiments to understand the upper ocean response to Bay of Bengal cyclones.
