Her research focuses on natural language processing, multimodal processing, and computational social science. CareerRada Mihalcea has a Ph.D. in Computer Science and Engineering from Southern Methodist University (2001) and a Ph.D. in Linguistics, Oxford University (2010). In 2017 she was named Director of the Artificial Intelligence Laboratory at University of Michigan, Computer Science and Engineering. In 2018 Rada Mihalcea was elected as new VP for the Association for Computational Linguistics (ACL). Currently she is a Professor of Computer Science and Engineering at the University of Michigan, where she also leads the Language and Information Technologies (LIT) Lab[1]. Mihalcea has published over 220 articles since 1998 on topics ranging from semantic analysis of text to lie detection.[2] President Barack Obama granted her the Presidential Early Career Award for Scientists and Engineers in 2008.[3] Mihalcea is an outspoken promoter of diversity in computer science. She also supports an expansion of the traditional analysis of educational success, which tends to focus on academic behavior, to include student life, personality and background outside of the classroom.[4] Mihalcea leads Girls Encoded, a program designed to develop the pipeline of women in computer science as well as to retain the women who have entered into the program.[5][6][7] AwardsSarah Goddard Power Award, 2019.[8] Carol Hollenshead Award, 2018.[9] Honorary Citizen of Cluj-Napoca, Romania, 2013. Presidential Early Career Award for Scientists and Engineers (PECASE), 2009. Awarded by President Barack Obama.[10]ResearchRada Mihalcea is known for her research in natural language processing, multimodal processing, computational social sciences. In a collaboration she leads at the University of Michigan, Mihalcea has created software that can detect human lying.[11] In a study of video clips of high profile court cases, a computer was more accurate at detecting deception than human judges.[12][13][14] Mihalcea's lie-detection software uses machine learning techniques to analyze video clips of actual trials.[15] In her 2015 study, the team used clips from The Innocence Project, a national organization that works to reexamine cases where individuals were tried without the benefit of DNA testing with the aim of exonerating wrongfully convicted individuals.[16] After identifying common human gestures, they transcribed the audio from the video clips of trials and analyzed how often subjects labeled deceptive used various words and phrases. The system was 75% accurate in identifying which subjects were deceptive among 120 videos.[16][17] That puts Mihalcea’s algorithm on par with the most commonly accepted form of lie detection, polygraph tests, which are roughly 85 percent accurate when testing guilty people and 56 percent accurate when testing the innocent.[18] Beyond the courtroom, Mihalcea says, the software could be adapted for job interviews. But she notes there are still improvements to be made — in particular to account for cultural and demographic differences.[16] A possibly unique advantage of Mihalcea's study was the real world, high stakes nature of the footage analyzed in the study. In laboratory experiments, it is difficult to create a setting that motivates people to truly lie.[19] In 2018 Rada Mihalcea and her collaborators also worked on an algorithm-based system that identifies linguistic cues in fake news stories. It successfully found fakes up to 76% of the time, compared to a human success rate of 70%.[20] Media[https://www.youtube.com/watch?v=ZH6fbQ9YJkw Spotting Fake News.
