Sibi Catley-Chandar
My name is Sibi Catley-Chandar and I’m currently a senior AI research scientist at Motorola Solutions. Before this, I was a computer vision researcher at Huawei Noah’s Ark Lab London.
My research interests are in building multimodal systems with diffusion and vision–language models for resource-constrained, privacy-preserving, safety-critical settings.
Outside of research I enjoy running, skiing and walking the dogs with my wife.
