About me Who what how
I'm Matt. Or Trent. Or Matt Trent. I'm many places, but often found in San Francisco. I'm interested in nearly everything, most notably cooking, learning and creating new technology.
I'm a cross between a research scientist and a software developer. Practically, that means I do some combination of: observe and model phenomena, design algorithms based on said models, and craft usable implementations of those algorithms. My background is a mix of image processing, human visual perception and developing for new hardware and mobile platforms. I'm interested in machine learning, data analysis, sensors and how those will impact health and wellness.
Currently, I freelance and develop my own projects. Previously, I've worked with companies large and small, including Dolby, Pocket Pixels, BrightSide Techonologies and Mobify. If you're interested in what I can do, check out my curriculum vitae.
My Ph.D. thesis examined how our perception of images changes with their size and produced several methods to control how the image appears. I think it's pretty cool that machines can use knowledge of how we see to create better images for us.
I'm an avid biohacker and self-experimenter. I've benefited from taking the scientific approach out of the lab and applying it to everyday life. I feel it's not only important to collect data, but to distill it into actionable information. I was the Vancouver Quantified Self organizer, when I still lived there.
I really do like cooking.
I'm also an occasional world-traveller, photographer, martial artist, cyclist, miscreant, vagabond and wanna-be jalopy-racer. These and other activies have thus far occupied my time on this planet for the last 32.01 years.
Projects New or notable
Top-selling selective desaturation photography for iPhone and iPad. Working with Pocket Pixels, I redesigned the app's graphics framework. Based on GPU acceleration, the latest version includes interactive image adjustments and faster performance. After release, the app rose to #6 in the US store.
My doctoral research examined ways in which perception of images changes when they are viewed at different sizes. Due to the organization of the visual system, the appearance of blurred and sharpened edges depends on the width of the edge. Besides the study, we propose several methods to address the change.
I've been fascinated with focus and attention, both how they work and how they affect our day-to-day lives. I've conducted a few experiments to see how I spend my time on, and what changes in my daily routine affect my ability to focus. Herein contains some notes from a session I moderated.

Get in touch via email (my initials), Twitter or Facebook. Better yet, find me in person (that way we can have a drink). Whatever the reason: hiring me, collaboration, creating amazing things, tossing ideas around, or just plain old shooting the shit, I'm available.
