Meet Dr. Nikku Madhusudhan, the Indian-origin scientist who found potential life beyond Earth

Dr. Nikku Madhusudhan is an Indian-British Professor of Astrophysics and Exoplanetary Science at the University of Cambridge. He leads the team that found strong evidence of life on an exoplanet called K2-18b, which is 120 light-years away, using the James Webb Space Telescope.

One of the leading figures in the field of exoplanetary science, Dr Madhusudhan has significantly contributed to the understanding of exoplanetary atmospheres, planetary formation, and the potential for extraterrestrial life

Hailing from India, Dr Madhusudhan, born in 1980, started his academic journey with a B.Tech. degree from the Indian Institute of Technology (IIT) BHU. He then moved to the US to study at the Massachusetts Institute of Technology (MIT), earning an M.S. and later a PhD, both in Astrophysics.


Madhusudhan then embarked on postdoctoral research at prestigious institutions such as MIT, Princeton University, and Yale University. In 2013, he joined the University of Cambridge, where he currently serves as a Professor of Astrophysics.

Madhusudhan's most prominent contributions lie in the development of novel atmospheric retrieval techniques, which use the spectra of distant exoplanets to decipher their atmospheric composition. These techniques have allowed him and his collaborators to make several landmark discoveries.

Among these is the first-ever inference of a carbon-rich exoplanetary atmosphere, which he published in Nature in 2011, and the first detection of titanium oxide in the atmosphere of an exoplanet, which changed the way scientists approach planetary compositions.

His introduction and work on Hycean worlds, planets rich in hydrogen and may harbor liquid oceans beneath their atmospheres, has opened up new possibilities for the search for life beyond Earth.

In 2023, Madhusudhan's team made significant strides by detecting carbon-bearing molecules in the atmosphere of K2-18 b, a potential Hycean world, using the James Webb Space Telescope.

In April 2025, another landmark observation provided additional evidence for the presence of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), gases associated with living organisms on Earth.

This discovery suggests that these types of planets could have the right conditions to support life, broadening the scope of habitable worlds in the universe.

He has received numerous awards and recognition for his contributions to science, including the IUPAP Young Scientist Medal (2016), the MERAC Prize for Theoretical Astrophysics (2019), and the ASI Vainu Bappu Gold Medal (2014).

His work has been featured in prestigious journals such as Nature, The Astrophysical Journal, and MNRAS, and he has been widely cited by scientists working on exoplanetary research. He is also a regular contributor to the popular media, explaining complex astrophysical concepts to a broader audience and inspiring future generations of scientists.

His recent observation of “possible life” marks another milestone in his search for extraterrestrial life.
