  Nora Isacoff, nisacoff@ruccs.rutgers.eduis a 4th year student in Cognitive Psychology, working with Karin Stromswold in the Language Acquisition and Processing Lab. Nora is interested in the relationship between lexical meaning and concepts, the development of lexical access abilities, and especially the hierarchical structure of the lexicon, and she enjoys approaching her work from an interdisciplinary perspective. Nora presented her work at several conferences including The American Psychological Association, The Eastern Psychological Association, and the American Psychological Society. Nora has a B. A. in linguistics from University College London. In addition to taking classes in psychology, linguistics, philosophy and computer science, Nora enjoys singing in the Voorhees Choir at the Mason Gross School of the Arts.

Gwendolyn Rehrig,, is a 3rd year student in the Cognitive Psychology program working with Karin Stromswold.  She graduated from Lehigh University in 2011 having completed a B.S. in Cognitive Psychology and a minor in Biological Sciences.  She is interested in the lexical semantics of verbs, the organization of verbs in the lexicon, the syntactic properties of verbs, and how events as perceived or experienced by observers correspond to verbal events. 

  Gaurav Kharkwal,, is a 2nd year student in Cognitive Psychology, and is also working towards a degree in Computer Science. He graduated from International Institute of Information Technology - Hyderabad in 2009 with a Bachelor's in Computer Science and Engineering (Hons). He is currently working with Karin Stromswold and investigating the relationship between linguistic and visual processing. His other interests are in cross-linguistic information dynamics and, very broadly, corpus linguistics.

Aaron Kheifets,, is a 3rd year student in Cognitive Psychology. He is working with Randy Gallistel and Jacob Feldman. Aaron received his Bachelor's from Reed College in math and philosophy. Aaron's interests lie in probabilistic inference, concept learning and referring to himself in the third person. Before beginning his PhD program at Rutgers, he worked in the labs of Randy Gallistel and Rochel Gelman on numerical learning, and is extremely grateful to them for helping him find a home here at RUCCS. In his spare time, Aaron enjoys playing accordion and ukulele poorly. You have been warned.

  Sung-Ho Kim,, is a 4th year student in the Psychology Department. He is currently studying how figure/ground organization constructs and reconstructs surface structure of the visual world. He is interested in issues such as how factors like motion or object shape influence surface representation, how the perceptual system interacts and coordinates with the action system, and how the perceptual system is self-organized. He is working with Jacob Feldman and Manish Singh. Sung-Ho received his BA and MA in Psychology from Seoul National University in Korea. His past work in Korea was on the object-based encoding effect in visual working memory.



Chris Mansley is a 6th year student in Computer Science. He completed his B.S. in Computer Engineering from Lehigh University in 2003. He left academia to pursue a real job developing aerospace software for general aviation. Eventually, he returned to the ivory tower to earn his M.S. in Computer Science at Lehigh in 2006, where he had the opportunity to work in robotics, performing optimization problems on cute robotic dogs. In a slight detour, he abandoned robotics to work in machine learning. He now hopes to bridge the gap between the computational worlds of computers and neurophysiology, psychology, and philosophy to extend robotics and machine learning in new and interesting directions.
  Peter Pantelis,, is a 4th year student in Cognitive Psychology, working with Jacob Feldman. Peter received his B.A. from the University of Pennsylvania with majors in psychology and political science, and performed his undergraduate research on face-name association with Dr. Michael Kahana. He is currently exploring how people infer the mental states of animate objects in the world, using their motion as a cue. Peter is quite proud to have been born and raised in beautiful New Jersey.
  Nick Ross,, is a 4th year student in the Cognitive Psychology program. He received a B.A. in Psychology from Stockton College in New Jersey ('08). He is working with Dr. Eileen Kowler on how different streams of information, presented in either the same or different modalities, are integrated during a divided attention task.
 Kevin Sanik,, is a 5th year student in the Computer Science department. Kevin received his B.S. in Computer Science and Mathematics from Purdue University. During his studies he started his (soon to be) career in research through the Psychology Department, spurring his choices in his field of study. He is interested in computer vision and modeling human vision, and is working with Doug DeCarlo.

 rachelRachel Sparks,, is a 3rd year student in biomedical engineering.  She completed her B.S. in bioengineering from the University of Washington in Seattle. She is tied into the Perceptual Science program because she is interested in using techniques of computer vision to aid classification of medical images leading to more robust diagnostic tools. Her current project is in Dr. Metaxas' lab, focusing on classifying heart motion using tagged MRI images.
