Exploring astronomy through research, observation, and teaching.

I work across exoplanet atmospheres, strong gravitational lensing, dark matter, observational astronomy, and astronomy education.

My background combines Electrical and Electronic Engineering with astronomy research, scientific computing, Astronomy Olympiad training, and open educational resource development. Since 2018, I have also served as Bangladesh Team Leader for the International Olympiad on Astronomy and Astrophysics.

Seeking graduate opportunities: I am actively hoping to pursue an M.Sc. or Ph.D. in Astronomy/Astrophysics and welcome contact from prospective supervisors or research groups whose work aligns with my background and interests.
