My group and I focus on the development of behavior and the impact that stressors have during sensitive phases. We quantify the impacts stressors have on perception, learning and memory, affective states and changes in neural plasticity. In a related project we address the capacity for awareness in animals and how this influences pain and suffering.
Sonia Cavigelli
We work on the influence of temperament and social status on stress and health; individual differences in stress and health in the natural environment; development of temperament/personality.
John Collins
(814) 863-0783
The overall goal of my work is to understand how large-scale neural systems perform information processing: What algorithms are/can be used, and what are the semantics of neural representations? This concerns both biological systems and engineered applications. Particular interests include: (a) the role of neurogenesis and synaptogenesis in memory formation; (b) the role of massive feedback connections (as in the visual cortex) in learning, in perception, and in the self-organization of neural systems.

I work on human cognitive neuroscience of aging, learning and memory, implicit learning, episodic memory, relational memory, false memory, cognitive control and fMRI
Nancy Dreschel
My research has focused primarily on fear and stress in companion animals and their human handlers. I am particularly interested in biobehavioral measures of canine, feline, and human interactions. My interests include human and animal public health, animal welfare, and canine cognition.
Paula Droege
My research in the philosophy of mind focuses on the difficult question of how consciousness and other mental processes might be produced by a physical thing like a brain. Drawing on work in phenomenology and biological functionalism, I argue that consciousness has evolved as a way for the mind to represent time. Conscious states represent the way the world is at the present moment in order for the creature to assess where it has been and how best to proceed.
Chuck Geier
Research aims to characterize developmental changes in basic affective and cognitive brain mechanisms that underlie these components of decision-making in adolescence. In particular, I am interested in understanding brain systems that mediate anticipatory and consummatory (outcome) responses to incentives (rewards, losses) and how these relate to the development of cognitive control, including inhibitory control and working memory. I am also keenly interested in how risky behaviors, such as cigarette smoking, might be more rewarding to adolescents than adults and how this, in combination with limitations in cognitive control, might lead to initial experimentation with the drug and dependence. The conceptual model that guides much of my research is that it is the interaction between incentive (reward, punishment) processing and basic cognitive control abilities, both of which are still maturing in adolescence, that sets the stage for suboptimal decision making and risk taking, including substance use.

I study the development of neural mechanisms engaged in dynamic perception and action planning. My research involves behavioral, neuroimaging (EEG and fMRI), and computational methods. Current projects focus on studying the development of self- and object motion processing and human and computer-based mechanisms associated with the detection of visual symmetry. I am also involved in a large-scale effort to create an open repository for video-based behavioral science data.
Christina Grozinger
My group’s research focuses on the genomic analysis of social behavior in honey bees and other social insect species. We are primarily interesting in understanding the molecular basis and evolution of chemical communication and host-parasite interactions. We are characterizing the molecular, physiological, behavioral, and social factors that regulate these processes. These studies not only shed light on the molecular pathways underlying behavior, olfaction, immunity, and chemical ecology, but can also serve as the basis for applied research into novel methods for improving honey bee breeding, colony health and management.

My research examines the effects of brain injury and disease on functional brain organization. One primary goal of our work is to understand how distributed neural networks are altered following significant neurological disruption (e.g., traumatic brain injury).  Using functional MRI and high density EEG our work examines short-term plasticity during task acquisition (i.e., new learning) as well as whole-brain changes occurring during the first year after injury.  Two important facets to this work are the:  1) integration of network modeling (e.g., euSEM, graph theory) to document network changes and 2) focus on individual differences in recovery to address the heterogeneous effects of injury on neural systems.
David Hughes
My group and I are interested in parasites that control the behavior of their hosts. Working with model systems in tropical and temperate habitats we explore disease dynamics, defense and the evolution of manipulative strategies. A major focus is moving into a proximate level view in an effort to understand how a single celled organism in one Kingdom (Fungi) alters the CNS of a multicellular organism in another Kingdom (Animalia).

The research in our group focuses on computational models of generation and perception of complex birdsong, and robust recognition of auditory objects such as speech in the auditory system. The work is done with close collaborations with experimental groups.
Byron Jones
Individual differences in response to drugs affecting the central nervous system
Kathleen Keller
My laboratory studies eating behaviors in young children, in particular, how do they develop and how are they related to risk for obesity later in life. We are using techniques such as brain imaging and genetic screening of taste polymorphisms to provide insight into the biological underpinnings of eating behaviors and food preferences in children. Also, we are researching the impact of food marketing and branding on these eating behaviors.
Judith Kroll
The research that Dr. Kroll and her students conduct concerns the acquisition, comprehension, and production of two languages during second language learning and in proficient bilingual performance.
Alex Kozhevnikov

Our research group studies the neural mechanisms of the birdsong, in particular the neural substrates that underlie the syntax of the birdsong. Also, we are involved in development of novel techniques/devices for neural recordings and manipulations of neural circuits.
Tracy Langkilde
I am interested in the physiological and behavioral consequences of novel stressors. My research examines the impact of invasion by predatory and venomous red imported fire ants on native lizards. We are finding that lizards from populations exposed to these invasive ants have elevated levels of corticosterone (CORT, a stress hormone), altered antipredator behavior, and increased behavioral sensitivity to CORT. I plan on investigating neural mechanisms, including changes in CORT receptors, that could be driving these patterns.

I am working on computational methods for large scale spiking neural networks, for both biological understanding and robotic applications. I also work on cognitive robotics, which involves using cognitive architectures (e.g. Soar) and decision trees on mobile robots (land-, air-, and sea-based). A key element of both these topics is machine learning.

David Andrew Puts
My lab studies the evolution and development of human sex differences. We are especially interested in how sex hormones contribute to sex differences in behavior, psychology, the brain, and other aspects of our phenotypes such as our voices, faces and bodies--and in why we evolved these sex differences and responses to sex hormones.
William Ray
Dr. Ray is currently the Director of the SCAN (Specialization in Cognitive and Affective Neuroscience) program and was previously the Director of the Clinical Psychology Program. His research has focused on approaching clinical questions from a neuroscience perspective. He has used psychophysiological and brain imaging techniques such as EEG, MEG, and fMRI to study emotionality, psychopathology and individual differences. These studies can be found in over 100 articles, book chapters and books. This work has been funded by both national and international agencies including NIH, NIMH, NASA, NATO, and the DAAD.
David Rosenbaum

David Rosenbaum is interested in the cognitive substrates of skilled performance, especially those underlying human motor control and perceptual-motor integration. He focuses on the planning and control of manual performance (mainly reaching and grasping objects), using computer modeling and recording of behavior. He also works on rhythm and timing, temporal coordination of cognitive and perceptual-motor activities, and how people organize their external environments.
Suzy Scherf

My core interests lie in understanding how children form representations of the visual world and how emerging functional specificity of the developing brain supports this process. Specifically, I am interested in the developmental trajectory of face representations because the discrimination and recognition of faces is one of the most taxing perceptual challenges confronted by people in their day-to-day life. I employ converging methodologies, including functional and structural magnetic resonance, and diffusion tensor imaging along with detailed behavioral paradigms in both typically developing populations and those with developmental disorders, with particular emphasis on autism, to examine development across multiple time points from early childhood to adulthood.
Janet Van Hell

Her research focuses on second language learning and bilingualism as well as later language development in children with typical or atypical language development. She combines behavioral, neuropsychological, and linguistic techniques to study language development and language processing.
David Vandenbergh
Control of neuronal gene expression by drugs of abuse
Daniel Weiss
My primary interest is in the domain of language acquisition and statistical learning (i.e., how learners track the distributional properties of speech). Recently, this work has begun to explore how language learners are able to track multiple inputs and non-uniform distributions. I adopt a comparative approach, studying these mechanisms in infants, adults and nonhuman primates. I also maintains an active research program studying motor planning and cognition/communication in nonhuman primates.
Brad Wyble
My lab studies the temporal resolution of visual perception at the intersection of attention and memory. We use psychophysics, computational modeling and ERP studies to explore how behaviorally-relevant information is detected by the visual system and then encoded into memory as consciously reportable representations.
