Hey there!


I am Sagnik, a mathematics grad and a visual creative.

I completed my integrated MS with a major in Mathematics and a minor in Biology from IISER Thiruvananthapuram. I wrote my major thesis under the supervision of Dr. Srilakshmi Krishnamoorthy, on problems in quadratic class field theory and my minor thesis under the supervision of Prof. Srinivasula Murty, on algorithmic analysis of tumor tissue imaging.

I am still in the process of building this little space on the web and planning to collate my writings and jot down quick notes / resources as and when I get time. Stay tuned.

While at IISER, I co-founded the institute mathematics club, CMIT in 2018, and have been engaged with it since then. To know more about the latest at the club and get involved, check out our website or contact via email.

Apart from mathematics, I spend my time obsessively listening to music, watching films, and creating visual art through photography, videography, and design. I also enjoy traveling, cycling, and playing Dungeon & Dragons. I am always up for interesting conversations, so if you would like to get in touch, feel free to drop me an email or find me around the internet.

→ Currently, I am also working on creative projects as a science communicator, freelance filmmaker and photographer. If you have a project in mind, do get in touch.
