Shayan Shekarforoush

I am a CS PhD Student at University of Toronto, and a graduate researcher at Vector Institute. I am fortunate to be supervised by David Fleet and Marcus Brubaker, and closely collaborate with David Lindell.
I interned at Samsung AI Center during summer 2022, working with Alex Levinshtein on dual-camera image enhancement.
I also did two summer internships at Technical University of Munich (2018, 2019) with Nassir Navab, working on Geometric Deep Learning and GNNs. I received my B.Sc. in Computer Engineering from Sharif University of Technology, Iran.

Research

My research interests broadly span CV and ML. In particular, I am interested in the cryo-EM 3D reconstruction. I design neural implicit representations as well as pose estimation methods to be used in 3D structure determination in cryo-EM.

	CryoSPIN: Improving Ab-Initio Cryo-EM Reconstruction with Semi-Amortized Pose Inference Shayan Shekarforoush, David Lindell, Marcus Brubaker, David Fleet NeurIPS 2024 (+ Oral in ML for Structural Biology workshop) arXiv / project page / code We introduce cryoSPIN, a new approach to ab-initio cryo-EM 3D reconstruction using semi-amortization to accelerate convergence and multi-head encoder to handle pose uncertainty.
	Dual-Camera Joint Deblurring-Denoising Shayan Shekarforoush, Aman Walia, Marcus Brubaker, Kosta Derpanis, Alex Levinshtein arXiv / project page A new method for joint image deblurring-denoising using a burst of short exposure images synchronized with a long exposure image, captured using a dual-camera rig. Deblurring is guided with flow/motion information estimated from the burst.
	Residual Multiplicative Filter Networks for Multiscale Reconstruction Shayan Shekarforoush, David Lindell, David Fleet, Marcus Brubaker NeurIPS 2022 arXiv / project page / code A new coordinate network and training scheme for optimizing multi-scale representation in a coarse-to-fine fashion.
