Bio and Research Interests
I grew up in the beautiful Pacific Northwest, and due to my passion for the outdoors and outdoor photography, I love it here. Feel free to see a gallery of some of my outdoor photos. I am of the opinion that one's life should be constructed in a conscious, deliberate, compassionate way based on the best scientific evidence, and with consideration for the interests of all life-forms: I view this as a universal perspective, because it minimizes observer-specific bias. To that end, I am passionate about topics such as environmental protection, animal rights, rights of nature, whole plant foods, following lifestyle medicine guidelines, higher education and the scientific process such as encountered in doctoral programs, long-term investing such as through index funds especially in companies with low emissions, 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. 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.
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.
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).
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.
