 Merlin is a senior research scientist at NVIDIA. His research focuses on differentiable physically based rendering, including how to efficiently and accurately computing gradients through rendering algorithms. These gradients can then be leveraged in a variety of inverse tasks, such as recovering the materials and lighting from photographs. He contributed to the development of the [Mitsuba](https://mitsuba-renderer.org/) differentiable renderer.
