Lab Members


Emmorey Dr. Karen Emmorey
email address

Dr. Karen Emmorey is a Professor in the School of Speech, Language and Hearing Sciences at San Diego State University and Director of the Laboratory for Language and Cognitive Neuroscience. full bio

Batch Cindy O'Grady Farnady
email address

Cindy O'Grady Farnady is a native signer and has been involved in sign language research for over 15 years. She is currently a Research Assistant at LLCN. She also works at the Salk Institute conducting research on Deaf individuals who have had a stroke. In addition she consults with graduate students on linguistics, translating and interpreting tasks. Her interests include running, cycling, traveling, cooking and reading. She looks forward to meeting you when you visit the lab.

giezen Dr. Marcel Giezen
email address

Marcel Giezen received his M.A. and Ph.D. in Linguistics from the University of Amsterdam in the Netherlands. His dissertation research focused on speech and sign perception in deaf children with cochlear implants. He came to San Diego in 2011 to work as a postdoctoral research fellow at the LLCN with a grant from the Netherlands Organisation for Scientific Research that investigated cross-language interactions in hearing signers using behavioral and eye-tracking measures. His current research interests are bimodal bilingualism, working memory, and phonological and lexical processes in language production and comprehension.

McCullough Dr. Stephen McCullough
email address

Stephen McCullough is a Research Scientist in LLCN. He uses functional Magnetic Resonance Imaging (fMRI) to investigate the neural systems that underlie sign language and the cognitive systems that support sign language processing (e.g., face recognition, motion perception).

Petrich Dr. Jennifer Petrich
email address

Jennifer Petrich received her Ph.D. in Neuroscience from the University of Maryland, Baltimore in 2004. Dr. Petrich's previous research focused on visual motion processing and attentional processing differences between normal and dyslexia readers and between deaf signers and hearing non-signers. Currently, Dr. Petrich's interests lie in studying the neural mechanisms that underlie language and motion processing in deaf signers.

Sevcikova Dr. Zed Sevcikova-Sehyr
email address

Zed Sevcikova Sehyr received her Ph.D in Cognitive Perceptual and Brain Sciences from University College London, Deafness, Cognition and Language Research Centre (DCAL). Her project examined perception and categorization of handling constructions in British Sign Language and gesture. In DCAL, she also worked as a research assistant on a project investigating acquisition of predicate structures, gesture and embodiment (constructed action) by deaf children with various BSL backgrounds. Zedís research interests currently include the role of short-term memory in fingerspelling and print and the effects of modality on spatial processing.

Weisberg Dr. Jill Weisberg
email address

Jill Weisberg received her Ph.D. in Neuroscience from Georgetown University, where she used functional brain imaging to examine spatial processing and object recognition in deaf and hearing populations. Since 1993, she has also been a member of the Laboratory of Brain and Cognition at NIMH, focusing on various aspects of learning and memory. Those studies explored how concepts are represented in the brain (e.g. objects concepts, social interaction) using functional brain imaging. Prior to that, Jill completed a B.A in French and an M.A. in Experimental Neuropsychology at George Mason University.

Students and Volunteers

arnol Brittany Arnold

I am currently a senior in the Speech, Language, and Hearing Sciences program at San Diego State University. I was first introduced to Deaf culture three years ago and became fascinated by the language and community surrounding it. I took my first ASL class the following year and continued to be immersed in the language. I am currently a member of the SDSU ASL Club as well as an executive board member for International Deaf Education Advocacy and Leadership (IDEAL). I am eager to learn more about sign languages in the LLCN and gain knowledge and skills I can refer to in my future profession.

brozdowski Chris Brozdowski

Chris Brozdowski is a PhD student in the UCSD/SDSU Joint Doctoral Program in Language and Communicative disorders. He received his B.S. in Cognitive Science and Psychology & Linguistics from The University of Connecticut. There, he spend time working on phonological development in ASL with Diane Lillo-Martin, Path and Manner expressions in Nicaraguan Homesign with Marie Coppola and semantic network modeling of abstract and concrete terms with Jim Magnuson. He's interested in the cognitive effects of sign language use as well as measuring language activation in bimodal bilinguals.

cox Travis Cox

I am currently a senior at San Diego state in the speech, language, and hearing sciences major. I grew up in Los Angeles. I first started studying ASL at Santa Monica community college where I have studied up to ASL 2 and I hope to take ASL 3 sometime soon. I hope to continue my education in getting my masters degree in speech language pathology after I graduate from San Diego State

Denny Nicole Denny

I am currently a Junior in the Speech, Language and Hearing sciences program at San Diego State University. While enrolled in my first ASL course at Santa Barbara City College I became very interested in not only the Deaf culture but also ASL. I became an active member of the ASL club at SBCC and quickly immersed myself in the Deaf community. I am now a member of the SDSU ASL club and have continually enjoyed to learn about Deaf culture and sign languages. I am excited to begin working in the LLCN and hope to apply the knowledge and skills that I learn there to my future career.

kartheiser Geo Kartheiser

Geo Kartheiser is a Ph.D. student in Educational Neuroscience at Gallaudet University and a research assistant with the Petitto Brain and Language Laboratory (BL2) and the NSF Center on Visual Language and Visual Learning (VL2). He received his B.S. in advertising and public relations from Rochester Institute of Technology. He has assisted research on visual attention, brain plasticity, and signed language assessment tools. His work investigates how the timing and modality of language acquisition impacts the neural networks that support language, learning, and higher cognition. He is also interested in how scientists can improve their relationship with the public. When not wearing the lab coat, Geo enjoys cycling, running, and eating exotic food.

Secora Kristen Secora

Kristen Secora is a PhD student in the UCSD/SDSU Joint Doctoral Program in Language and Communicative Disorders. She received her B.S. in Neuroscience from Texas Christian University. She is studying motion processing in sign languages within the framework of embodied cognition.

sumathipaia Mahie Sumathipaia

Mahie is currently a senior, majoring in the Speech, Language and Hearing Sciences program at San Diego State University. After taking her first ASL class two years ago, she quickly became deeply involved with the Deaf community, locally and internationally. She is the Assistant Director of program development for the non-profit I.D.E.A.L (International Deaf Education, Advocacy and Leadership); working with Deaf communities in five East African countries and in the process of extending this to other regions. She is excited to be learning more about sign language in a research setting and gaining practical skills that will be of great value for her future goals.

udoff Jonathan Udoff

Jonathan Udoff is a PhD student in the UCSD/SDSU Joint Doctoral Program in Language and Communicative Disorders. He received his BA in Cognitive Science and Hispanic Studies from Brown University in 2007. At Brown, Jonathan became involved in ASL classes and the ASL club, leading him to spearhead Brown's "Save ASL" campaign in the spring of 2005. Jonathan's research focuses on the psycholinguistics of sign languages and of bilingualism. He is particularly interested in how bimodal bilingualism differs from mono-modal bilingualism. In addition to ASL, Jonathan speaks Spanish and Catalan.

weber Jordan Weber

Iím currently a second year masters student in the Speech, Language, and Hearing Sciences (SLHS) program at San Diego State University (SDSU). I received my B.A. also in SLHS at SDSU and minored in neuroscience. My current interests are providing speech therapy to children who are deaf & hard of hearing and older adults who have neurogenic language disorders.
