Data Science Intern @ Artie · MS Data Science @ ColumbiaDS Intern @ Artie · MS @ Columbia

Hi, I'm Ishmeen — I turn messy, real-world problems into intelligent, data-driven systems.

Data Science graduate student at Columbia University working across machine learning, causal inference, forecasting, and AI — building things that are technical enough for research and practical enough to ship.

About me

Researcher, builder & curious explorer.

I'm a Master's in Data Science student at Columbia University with a background in Computer Engineering (CGPA 9.66/10) and 5 peer-reviewed publications in IEEE and Springer. I work at the intersection of machine learning, causal inference, forecasting, and data-driven product decisions — taking complex problems and turning them into practical, scalable solutions.

I'm currently a Data Science Intern at Artie, and have previously interned at Deloitte and IIT Roorkee — alongside my role as a Graduate Student Assistant at the Northeast Big Data Innovation Hub at Columbia. Beyond the data, you'll find me wandering through Central Park or Riverside Park, hunting for new coffee shops and bookstores, and buying the most random things from Five Below. 🌸
