My background

From engineering student to astronomy researcher and educator.

My path into astronomy has combined self-directed learning, international Olympiads, observational training, research, scientific computing, and years of teaching students.

I completed a B.Sc. in Electrical and Electronic Engineering in 2023, while building my astronomy experience through research projects, international programs, and the Bangladesh Olympiad on Astronomy and Astrophysics.

Graduate-study goal: I am actively hoping to pursue an M.Sc. or Ph.D. in Astronomy/Astrophysics. I am particularly interested in hearing from prospective supervisors and research groups working in areas connected to my research experience.

Profile

A compact summary of the experiences that connect the rest of this portfolio.

Education

B.Sc. in Electrical and Electronic Engineering, BAUET, 2023.

Research

Exoplanet atmospheres, strong gravitational lensing, dark matter, and astronomy education.

Olympiads

International participant, trainer, academic coordinator, and Bangladesh Team Leader since 2018.

Education & writing

Astronomy books, Olympiad notes, observational resources, and open learning tools.

Background

How astronomy became central to my work

Starting as a student

I began learning astronomy largely through freely available books, lectures, problem sets, and online resources. Science competitions gave that self-study a structure. I represented Bangladesh at IOAA 2016 and later at IESO 2017, where I received a Bronze medal as a participant.

From participant to trainer

In 2018 I became involved in building the Bangladesh Olympiad on Astronomy and Astrophysics (BDOAA), serving as an academic coordinator, coach, and Bangladesh Team Leader. Teaching Olympiad students became an important part of how I learned to explain technical astronomy clearly and systematically.

Research and scientific work

My research experience developed alongside that educational work. LEAPS 2020 introduced me to high-resolution exoplanet spectroscopy. I later worked on strong gravitational lensing and the internal structure of massive elliptical galaxies, and that project culminated in an Astronomy & Astrophysics publication in 2025. In 2024 I joined CASSUM as a Research Fellow, working on exoplanet atmospheric modeling and synthetic observations. My current work also includes astronomy-education research and Olympiad knowledge graphs.

These areas may look different, but they are connected by the same interests: observation, quantitative reasoning, scientific modeling, and making astronomy easier to learn without removing the mathematics and physics.
