Dawn Song is a computer security specialist who applies rigorous theoretical methods to understand the deep interactions of software, hardware, and networks that make computer systems vulnerable to attack or interference. Computer security failures can lead to dissemination of spam email, systemic disruption of communications traffic on the internet, and unauthorized access to confidential information. Rather than identifying errors in programming logic that lead to specific security breaches, Song investigates the underlying patterns of computer system behavior that often apply across whole classes of security vulnerability. Using a sophisticated method for semantic analysis of binary code (i.e., the machine-readable translation of human-readable programmers』 instructions) from disruptive software, Song can identify the common path of logic flow that similarly disruptive software must also follow, thus offering a means to protect against an entire set of potential security threats. As a surprising consequence, she has shown that software patches intended to fix existing security flaws can be used as a template for algorithms that autonomously generate similar but distinct computer programs that also exploit the flaw, and sometimes even circumvent the repair. Identifying such weaknesses represents an important step in developing generalized defenses against computer attack, instead of the more common approach of iterative, ad hoc corrections of inevitable human errors in software design. Song also helped to develop an efficient algorithm that can protect the most sensitive information using cryptography, even if a computer system』s first-line defenses have been compromised. By synthesizing advanced approaches from theoretical computer science and empirical software engineering, Song is making significant strides in increasing the security and stability of computer systems and networks, which have become essential elements of our social and economic infrastructure.
Dawn Song received a B.S. (1996) from Tsinghua University, an M.S. (1999) from Carnegie Mellon University, and a Ph.D. (2002) from the University of California, Berkeley. She was an assistant professor at Carnegie Mellon University (2002–2007) prior to her appointment to the Department of Electrical Engineering and Computer Science at the University of California, Berkeley, where she is currently an associate professor.

Yiyun Li is a fiction writer whose spare and quietly understated style of storytelling draws readers into powerful and emotionally compelling explorations of her characters』 struggles, set both in China and the United States. After moving from China to the United States in 1996 to pursue a graduate degree in immunology at the University of Iowa, Li shifted her studies to the Iowa Writers』 Workshop and focused on fiction writing in her adopted language of English. Her prose in this second language bears the inflections of her mother tongue and culture, lending a vivid and arresting quality to the voices and experiences she presents to English-speaking readers. In her story collection A Thousand Years of Good Prayers (2005), Li inhabits the lives of ordinary individuals, rendering their separate predicaments with empathy and a keen eye for illuminating details that give each character depth and nuance. Through these intimate and elegantly constructed portraits of people largely ignored by history—Chinese nationals as well as expatriates in the United States—Li magnifies and dramatizes the myriad effects of late-twentieth-century China』s political upheaval and sweeping social changes. She expands upon related themes on the larger canvas of her novel The Vagrants (2009), which depicts life in a provincial Chinese town during the turbulent years following Mao』s death in the late 1970s. The novel opens on the day a young woman is to be executed as a counter-revolutionary and proceeds to trace the intersecting fates of a wide-ranging cast of townspeople. In these and other works, Li crafts deeply moving fiction that offers Western readers a window into unfamiliar worlds as well as insights into human nature that transcend ethnicity and place.
Yiyun Li received a B.S. (1996) from Peking University, an M.S. (2000) from the University of Iowa, and an M.F.A. (2005) from the Writers』 Workshop at the University of Iowa. Since 2008, she has been an assistant professor in the Department of English at the University of California, Davis. Her additional works include Gold Boy, Emerald Girl: Stories (2010) and short stories and essays that have appeared in such publications as Granta, The New Yorker, and the Paris Review
