Dr. John TrueswellDr. Trueswell is the current director of the Institute for Research in Cognitive Science and the director of the IGERT Language and Communication Program. He received his Ph.D. from the University of Rochester in 1993 and is a professor in the Department of Psychology at Penn.

Dr. Lila GleitmanDr. Gleitman received the Ph.D in Linguistics from Penn in 1967 and after some years in the Linguistics Dept. at Swarthmore has been a professor of Psychology at Penn (now emerita); she is also a Visiting Professor in Cognitive Science at Rutgers University. With A. Joshi, she was founding Director of IRCS (1980-2000). Her research concerns the mental lexicon and the syntax-semantics interface, language acquisition, and the relation between language and thought. |

Dr. Ann BungerAnn is a postdoctoral fellow both at our lab and at the University of Delaware, where she works with Anna Papafragou (see below). She received her Ph.D. in Linguistics from Northwestern University. Her research focuses on the way that preschoolers describe events happening in the world around them and what this reveals about the way they understand the world. When not in the lab or driving up and down I-95, Ann is likely to be trying out new recipes or spending quality time in the mountains of Pennsylvania. |

Dr. Tamara Nicol MedinaTamara is a postdoctoral fellow in the lab. She found her way here via Johns Hopkins University (Ph.D. in Cognitive Science, 2007). Her research interests include word learning, conceptual development, verb meaning and argument realization, and syntactic theory. In 2008 she got her very own infant to study in her free time at home - they are currently working on learning new words and the occasional multi-word utterance. In her spare moments, Tamara thinks about how she used to have time for photography and travel. |

Hila Katz, Ph.D. studentHila, a second-year grad student in our lab, received her B.A. in psychology from Columbia University. Her research interests, for the indefinite future, will definitely include the definite and indefinite reference, along with a healthy dose of metaphor, humor, and irony. Outside of the lab she enjoys writing, reading, coaxing soft melodies from the piano, and taking long contemplative walks. |

Aviad Eilam, Ph.D. studentAviad is a fifth-year graduate student in the Department of Linguistics here at Penn. He received his B.A. in linguistics and psychology from Tel Aviv University in 2004. His lab-related interests include the acquisition of expletive negation and other context-sensitive items, first-generation Modern Hebrew as a case study of variable input acquisition, and the way in which children deal with parametric variation in syntax and morphology. When not in the lab, Aviad can be found in Williams Hall.

Alon HafriAlon started as the lab research assistant in January 2009, and has been enjoying his time here tracking eye movements, among other tasks. He received his B.A. in music from Wesleyan University in 2007, and volunteered as an R.A. at the Temple Infant Lab from 2007-2008 until settling here at Penn. He is an avid soup-maker (ask him about French Onion) and plays music around Philly in the Josh and Pete Band. |

Dr. Anna PapafragouAnna is an associate professor in the departments of Psychology and of Linguistics and Cognitive Science at the University of Delaware. She received her Ph.D. in Linguistics from University College London in 1998. Her main interests lie with language acquisition (especially of semantics and pragmatics) and the interface between linguistic and non-linguistic representations in adults and children. |

Carolyn Quam, Ph.D. studentCarolyn is a fourth-year Ph.D. student in the Department of Psychology at the University of Pennsylvania. She received her B.A. from Stanford University in 2004 with departmental honors in Psychology and a minor in Music. Her research addresses language-acquisition issues including acquisition of phonology, the application of phonological knowledge to word learning, and how regularities in the input constrain children's word-learning hypotheses. |

Sarah Johnstone Drucker, Ph.D. studentSarah is a graduate student in the Dahan lab. She's currently studying timing and order effects in spoken language comprehension. |

Ranjani Prabhakaran, Ph.D. studentRanjani received her Sc.B. in Neuroscience from Brown University in 2004. Her research focuses on the neural correlates of working memory, language processing, and the role of prefrontal cortex in executive functions. In particular, she is interested in the extent to which prefrontal cortex functions in a domain-general fashion across verbal and nonverbal domains. She is also interested in genetic influences on individual differences in cognitive control abilities. She is currently investigating the extent to which there is correlated variation in individual performance across cognitive control tasks in verbal and nonverbal domains. |

Elika Bergelson, Ph.D. studentElika Bergelson is a 2nd year graduate student in psychology, working under the supervision of Dan Swingley. She is interested in how and when infants learn the meanings and semantic classes of words, and is currently investigating this through research using eyetracking. She is also involved in research at UMD with Jeff Lidz and Bill Idsardi on phonological rule learning in infants and adults. |
