Chris Baker, Ph.D. | Investigator and Chief | Section on Learning and Plasticity
Dr. Baker received his B.A. in Neuroscience from Cambridge University in 1995 and his Ph.D. in Psychology from the University of St Andrews in 1999. He is Chief of the Section on Learning and Plasticity, focused on understanding the functional neuroanatomy of high-level vision (e.g. recognition of faces, scenes, objects) and the impact of learning and plasticity.

Joseph Arizpe, B.S. | Special Volunteer
Joseph is a doctoral student of Neuroscience in the graduate partnership program (GPP) with University College London (UCL).  He is jointly in the labs of Vincent Walsh (UCL) and Chris Baker (NIMH) researching face perception and plasticity in visual cortex using eye-tracking, neuroimaging, and transcranial stimulation techniques.

Annie Chan, Ph.D. | Special Volunteer
Dr. Chan received her B.S. and Ph.D. from the University of Wales, Bangor, UK. She joined the Laboratory of Brain and Cognition as a Visiting Post-Doctoral Fellow. Dr. Chan is now an Assistant Professor in the Department of Neurology, University of Tennessee Health Science Center. Her current research interests include multi-domain representations of the body, phantom limb pain, and cortical reorganization.

Iris Groen, Ph.D. | Visiting Fellow
Dr. Groen joined the LBC in 2014 after obtaining her Ph.D. from the University of Amsterdam, The Netherlands. Dr. Groen is interested in understanding the neural circuitry underlying our ability to rapidly perceive the content of real-world scenes, combining computational and cognitive neuroscience methods. In particular, she aims to characterize the brain networks involved in real-world scene understanding using computational image analysis, fMRI and brain stimulation. In 2015 she was awarded a Rubicon grant from the Dutch government to support her research at NIMH.

Assaf Harel, Ph.D. | Special Volunteer
Dr. Harel received his B.A. from Tel Aviv University, and his Ph.D. degree in cognitive neuropsychology from the Hebrew University of Jerusalem, where he investigated expertise in object recognition. Dr. Harel conducted postdoctoral research at the Laboratory of Brain and Cognition at the NIMH, studying the neural correlates of object and scene recognition. He is currently an Assistant Professor in the Department of Psychology at Wright State University, heading the Laboratory of Human Neuroscience and Visual Cognition.

Marcie King, B.A. | Post Bac Fellow
Marcie is a graduate of Georgetown University with a Bachelor of Arts in psychology. Ms. King works in the Section on Learning and Plasticity and assists with both behavioral and fMRI data collection and analysis. She is also responsible for recruiting and scheduling volunteers to participate in studies.

Dwight J. Kravitz, Ph.D. | Special Volunteer
Dr. Kravitz is an Assistant Professor in the Department of Psychology at the George Washington University. He received his Ph.D. in 2006 from Carnegie Mellon University in Pittsburgh, Pennsylvania, with M. Behrmann. He then performed research at the NIMH as a post doctoral fellow in the Unit on Learning and Plasticity with Chris Baker. Dr. Kravitz’ research focuses on understanding the neural circuits and mechanisms supporting visual attention, the representation of complex visual stimuli (such as faces, objects and scenes), and the modification of those representations by experience.

Sue-Hyun Lee, Ph.D. | Research Fellow
Dr. Lee joined the LBC in 2009 after receiving her Ph.D. from Seoul National University, Korea. Dr. Lee's research interests focus on the representation of visual information from memory in prefrontal, posterior, and medial temporal regions of the brain.

Brandon Levy, B.S. | Post Bac Fellow
is a graduate of Duke University with a Bachelor of Science in Neuroscience. Brandon assists with participant recruitment and scheduling as well as stimuli creation, paradigm development, and data collection and analysis in the Section on Learning and Plasticity.

Edward Silson, Ph.D. | Visiting Fellow
received his Ph.D. in visual neuroscience form the University of York, United Kingdom. Current research interests include the functional organization of human visual cortex and in health and disease and object and scene recognition.

Adam Steel, B.A. | Post Bac Fellow
Adam is a doctoral candidate in the NIH/Oxford-Cambridge Graduate Partnership Program. He is working with Chris Baker in the Section on Learning and Plasticity at the NIH and Charlotte Stagg in the FMRIB Department at Oxford University. His research is primarily concerned with the functional architecture of the cortex changes from experiences, such as learning a new skill, and how reward and punishment influences this remodeling.

Cibu P. Thomas, Ph.D | Staff Scientist
Dr. Thomas received his Ph.D. in Psychology from the Psychology Department and Center for the Neural basis of Cognition at Carnegie Mellon University in 2007. After Postdoctoral training at the Martinos Center for Biomedical Imaging at Harvard Medical School and additional training in the Unit on Learning and Plasticity (NIMH) and the Section on Quantitative Imaging and Tissues sciences (NIBIB), he is currently working as a Staff Scientist in the Section on Learning and Plasticity at the National Institute of Mental Health. He uses advanced structural and functional MRI techniques to understand the biological mechanisms underlying changes in the brain that can be associated with an adaptive or a maladaptive change in behavior.

Aaron Trefler, B.S. | Post Bac Fellow
Aaron graduated from UCLA with a B.S. in Cognitive Science with a Specialization in Computing. His current research involves using MRI imaging to identify the structural basis of brain plasticity.
