她和吴恩达2012年一同创办了线上教育平台Coursera。 她专精于人工智能研究 并积极发展在生医领域的应用。 她的研究工作专注在表现、干预、学习和决策，最近则关注电脑视觉和计算生物学。 科勒和史丹佛大学的安娜潘博士，一同开发了PhysiScore，采用各种数据要素来预测早产儿是否有健康问题。 2004年一篇来自麻省理工科技评论的文章"将改变世界的10个新兴技术" 中，科勒教授提及贝式网络的技术。

Daphne Koller (Hebrew: דפנה קולר; born August 27, 1968) is an Israeli-American computer scientist. She was a professor in the department of computer science at Stanford University and a MacArthur Foundation fellowship recipient. She is one of the founders of Coursera, an online education platform. Her general research area is artificial intelligence and its applications in the biomedical sciences. Koller was featured in a 2004 article by MIT Technology Review titled "10 Emerging Technologies That Will Change Your World" concerning the topic of Bayesian machine learning.

Early life

Koller was born on August 27, 1968, in Jerusalem, Israel. She received a bachelor's degree from the Hebrew University of Jerusalem in 1985, at the age of 17, and a master's degree from the same institution in 1986, at the age of 18. She completed her PhD at Stanford in 1993 under the supervision of Joseph Halpern.

Career and research

After her PhD, Koller did postdoctoral research at University of California, Berkeley from 1993 to 1995 under Stuart J. Russell, and joined the faculty of the Stanford University computer science department in 1995. She was named a MacArthur Fellow in 2004. She was elected a member of the National Academy of Engineering in 2011 for contributions to representation, inference, and learning in probabilistic models with applications to robotics, vision, and biology. She was also elected a fellow of the American Academy of Arts and Sciences in 2014 and as a member of the National Academy of Sciences in 2023.

In April 2008, Koller was awarded the first ever $150,000 ACM-Infosys Foundation Award in Computing Sciences.

She and Andrew Ng, a fellow Stanford computer science professor in the AI lab, founded Coursera in 2012. She served as the co-CEO with Ng, and then as president of Coursera. She was recognized for her contributions to online education by being named one of Newsweek's 10 Most Important People in 2010, Time magazine's 100 Most Influential People in 2012, and Fast Company's Most Creative People in 2014.

She left Coursera in 2016 to become chief computing officer at Calico. In 2018, she left Calico to start and lead Insitro, a drug discovery startup. The company operates an automated lab equipment running on algorithms that use its own in vitro disease models. The process allows the combination of machine learning and genomics to predict as well as test treatments for diseases.

Koller is primarily interested in representation, inference, learning, and decision making, with a focus on applications to computer vision and computational biology. Along with Suchi Saria and Anna Penn of Stanford University, Koller developed PhysiScore, which uses various data elements to predict whether premature babies are likely to have health issues.

Koller's work on artificial intelligence builds on Bayes' theorem, an 18th-century result about probability named after the mathematician Thomas Bayes. The approach underpins the process of transforming a current assumption about an event into a more accurate assumption based on more evidence. Koller is a leading figure in research that expanded the existing Bayesian-related software so that it is capable of discerning patterns in vast collections of data. In 2009, she published a textbook on probabilistic graphical models together with Nir Friedman. She offers a course on the subject.

In 2020, Koller co-founded the startup Engageli, which developed an alternative to the Zoom app. Its online learning platform addressed problems such as low student engagement, featuring what the company called as “superior” learning experience that includes real-time evaluations to determine whether students are keeping up.

Her former doctoral students include Lise Getoor, Mehran Sahami, Suchi Saria, Eran Segal, and Ben Taskar.

Koller was interviewed by BBC Radio 4 on The Life Scientific broadcast on 27 September 2022.
