ESA/AURA Astronomer
Nimisha Kumari headshot

As an ESA/AURA astronomer, Dr Nimisha Kumari devotes half of her time to supporting JWST and other half to conducting my independent research. She serves JWST currently as the Lead of the JWST Science Operations Calibration Planning Team and as the Calibration lead of JWST/NIRSpec Instrument. She joined STScI in 2019, as a STScI Prize Fellow in the HST/COS team.

Dr. Kumari’s research is mainly driven by questions related to galaxy formation and evolution, focusing on its three fundamental properties - chemical abundances, star-formation and gas-dynamics. She addresses these questions via observational studies of emission line galaxies, primarily using integral field and multi-object spectrographs.  She is also experienced with ultraviolet spectroscopy and multi-wavelength (FUV, optical, IR, radio) data analysis from various ground-based and space-borne instruments.

Before joining STScI in 2019, she was an independent research fellow funded by a Schlumberger fellowship, working mainly with Profs. Roberto Maiolino and Mike Irwin at the University of Cambridge. She also completed her PhD in Astronomy there in October 2018 supervised by Prof. Mike Irwin and Dr. Bethan James. STScI provided her a great opportunity to pursue an astronomy project as a summer student in 2013, when she worked as summer student with Dr. Andrew Fox. She cares about making education and astronomy available to children and students (especially from disadvantaged backgrounds), and has been a part of several outreach efforts.
