bio · Ryan Farrell is an Assistant Professor in the Computer Science department at Brigham Young University (BYU). He previously worked as a research scientist at the International Computer Science Institute (ICSI), a non-profit research institute affiliated with UC Berkeley, having completed his master's and doctorate degrees at the University of Maryland, College Park.
research · My research focuses on the emerging field of fine-grained visual categorization (FGVC), where, instead of recognizing objects at a coarse level (e.g. bird or car), we tackle the difficult task of training a computer to find the highly-localized and often subtle characteristics (differences in shape, coloration, etc.) that allow precise identification at the level of fine-grained or "subordinate-level" categories (e.g. genus/species, make/model/year). Overcoming this key challenge bridges the divide between objects in the visual world around us and the vast wealth of digital information about them.

personal · The most important things in my life are my family and my faith. I consider myself fortunate to be married to my best friend and sweetheart and to be a devoted father to three wonderful children. I spend most of my free time with them and with friends. When occasion permits (and it rarely does these days), I pursue my favorite hobby, birding.
