Darius Siwek’s work is the place where art and science meet. Clients such as Caltech, research scientists at major universities, and start-up companies rely on him to translate technical concepts, inventions, and products into dynamic images. Researchers work with him as they apply for grant money; engineers hire him during the patent application process; think tanks and labs needing to spread the word about their latest innovations get him to produce cover artwork for major science journals. He does the work with the expected flair of an artist but works closely with the client to ensure a faithfulness to science.
