I am an astronomy PhD candidate at Leiden Observatory. My research is on galaxy evolution in dense environments like galaxy groups and clusters. I use data from observations and cosmological simulations to understand the growth of mass and light in these systems over cosmic time. Before this, I got my Erasmus Mundus joint MSc degree in Astrophysics where I studied in Austria, Italy, and Germany. I am from Bangladesh where I got my BSc degree in Electrical and Electronic Engineering in 2015. Apart from research, I enjoy science outreach, painting, travelling, and writing in my blog (mainly in Bengali).
