Welcome to my site! 

My name is Ashu Kushwaha, and I am currently a postdoctoral fellow at the Department of Physics, Indian Institute of Science Bangalore. I did my PhD under the supervision of Prof. S. Shankaranarayanan at Astronomy, Cosmology and Gravity Group,  Department of Physics, IIT Bombay. I did my postgraduate degree in physics from the School of Physical Sciences (SPS) at Jawaharlal Nehru University (JNU), New Delhi. Before that, I was an undergraduate at Ramjas College, Delhi University.


Apart from my academic pursuits, I have a keen interest in the arts and music. I am an avid painter and love expressing my creativity through vibrant, abstract, semi-abstract pieces. I often experiment with different techniques and styles to create unique and original works of art. In the recenlty completed 10-paintings series, I tried to explore a new version of cubism. Visiting art galleries and exhibitions is another one of my favourite hobbies. I find inspiration in the work of other artists and enjoy exploring their perspectives and interpretations of the world around us.

As a travel enthusiast, I enjoy exploring new destinations and experiencing different cultures. I believe that traveling is a great way to broaden our horizons and gain new perspectives on life. My travels have taken me to many beautiful and exotic places, and I have enjoyed immersing myself in the local customs, traditions, and way of life.

Lastly, I am an avid photographer and love capturing the beauty of the world around me. I find that photography is a great way to preserve memories and share my experiences with others. This also gives me a great idea for painting subjects.

 Please check the artwork section if you wish to see some of my selected artworks. I hope you will enjoy that, if you want to make any comments, criticism, or suggestions, please send me an email given at the bottom of this page. I would really appreciate that.

Unlike science, art has no mathematical notion of beauty. Consequently, individuals are free to interpret the art in their own manner. However, it is always good to understand the artist's intention.

At some point and time, I would like to share my intention about the artwork. Stay tuned!

The origin of the cosmological magnetic field is an unresolved issue in modern cosmology. There is no compelling theoretical model to explain the presence of micro-Gauss strength magnetic fields in the galaxies and galaxy clusters. However, they could be of primordial origin and might have been generated due to cosmological processes during the early universe, specifically during inflation. In my PhD thesis, I  studied constructing consistent field theoretical models to generate the primordial magnetic field with a primary focus on physics during the inflationary epoch. I have also studied the interesting consequences of small-scale magnetic fields (of compact objects).


Thank you for taking the time to learn more about me, and I hope you enjoy exploring my website further.  This webpage is under construction, and will always be.
