Bio and Research Interests
I grew up in the beautiful Pacific Northwest, and due to my passion for the outdoors, I love it here. Feel free to see a gallery of some of my photos. I am passionate about outdoors activites such as running, kayaking, snowskiing, hiking, and mountain biking. I also like environmental protection, animal rights, whole plant foods, following lifestyle medicine guidelines, higher education and the scientific process such as encountered in doctoral programs, and living a sustainable, low-carbon lifestyle working for green companies. Happily, Adobe does a pretty good job in terms of sustainability.
My career has focused on computer science research with numerous Adobe and academic collaborators, and particularly on algorithms used by photographers. Currently, I work mainly on computer graphics and vision topics, such as image and video processing, texture, deep learning for image tasks, and domain specific languages especially for shaders. I organize an Adobe initiative called ICE: Image Inpainting, Clean-up, and Extrapolation, where we focus on research and development related to those image editing topics. For the years 2013-2017, I was an assistant professor of computer science at the University of Virginia.
Please see my C.V. or my publications below for more information.

Internships
I will be recruiting computer science Ph.D. students for Adobe research internships, which typically result in peer-reviewed publications. If you are interested, please apply. I suggest you send myself and any other researchers with overlapping research interest an email. It helps if you can identify shared research interests. For summer internships, it also helps if you do this in November.
Service
I have served on these technical papers committees: CGDIP (2017), Eurographics short papers (2013), Eurographics Symposium on Rendering (2013, 2014, 2017), ICCP (2013), Pacific Graphics (2017), SIGGRAPH (2015, 2016, 2019, 2020), SIGGRAPH Asia (2018, 2021).
Classes
If you are interested, you can see a list of classes that I taught when I was a professor.
Impact and Press Coverage
The PatchMatch technology that I researched for my Ph.D. was incorporated into Adobe Photoshop CS5 as content-aware fill. This received 8 million views on YouTube [1] [2], and was featured in press such as Popular Science and PC Magazine. In later Photoshop versions, Content-aware Patch, Move, and Color Adaptation were built on this technology [3]. With collaborators, I continue to work in that space.
I collaborated on the Halide project, which has been used at Adobe and Google. My collaboration on camouflage has been featured on Wired and Gizmodo, with 170,000 views on YouTube.
