Dara Varam

PhD in EDEE @ École Polytechnique Fédérale de Lausanne, specifically at the Embedded Systems Laboratory (ESL). Previously I did my MS in Machine Learning and my undergrad in Computer Engineering and Mathematics @ AUS with a minor in Data Science. I'm Iranian and I'm 24 years old.

From May 2025 to October 2026, I was a visiting researcher at the Senseable City Lab @ MIT.

My research focuses mainly on model compression, optimization and quantization for neural networks and LLMs. I have also done studies in training optimization, computer vision, and eXplainable AI.

The picture on the right isn't what I look like now. I just wanted to put it up there so you know I've always been cool 👺

Class Separation Dynamics in Vision Transformers: An Empirical Study

D. Varam, L. Khalil, M. Darwish, M. I. AlHajri

IEEE Access, 2025

We study the class separation dynamics of Vision Transformers (ViTs) as they train for classification tasks, empirically deriving two “laws” that are always followed as a function of training. These two laws have implications that can strongly guide the training strategy and model optimization for transformer-based learning.
