Hahn, Joel
Associate Professor (Research) of Biological Sciences
The overall goal / objective of my research is to increase scientific understanding of the fundamental structure/function relations of the nervous system. Using a variety of research methods, I have investigated neural circuits relating to specific functions (for example, neuroendocrine control of reproduction, eating, and agonistic behaviors), as well as high-level global network organization of the brain. My current research is geared mostly to developing and investigating nervous system network models, and to building tools and resources for systems neuroscience, and more recently for comparing neuroanatomical ontologies within and between species, to simplify and enable more accurate interpretation and communication of neuroscience data.
Han, S.Duke
Professor of Psychology and Family Medicine
The Han Research Laboratory is dedicated to improving the health, wellbeing, and independence of adults living into old age. We are interested in investigating the diverse factors and neurobiological mechanisms that impact cognition and decision making across the lifespan using multidisciplinary approaches informed by the fields of neuropsychology, cognitive and systems neuroscience, epidemiology, genetics, and behavioral economics.
Hires, Samuel Andrew
Associate Professor of Biological Sciences
The Hires lab is investigating the basis of biological intelligence. Over the past decade we developed numerous imaging tools to record large-scale patterns of neural activity that are used by thousands of neuroscience labs. These have resulted in hundreds of publicly available datasets embedded with rich representations of neural activity. We are now developing analytical tools, using recent AI developments, to ultimately distill undiscovered principles of biological intelligence from these datasets.

Our laboratory studies the thalamus, the interface between neocortex and the sensory periphery. Thalamus was once regarded as a simple gatekeeper, passively relaying information during waking and shielding neocortex from disturbance during sleep, but this is an impoverished view. We explore how thalamus, itself, contributes to sensory integration. In particular, we study the structure of neural circuits in the visual part of thalamus, how these operate during vision and how they extract and recode information from the eye. Our work shows how thalamus might contribute to visual processing by, for example, sharpening the visual image and increasing the efficiency of the neural code. Because circuits in different parts of thalamus are similar, our work pertains to thalamic function in general.
Jakowec, Michael
Professor of Clinical Pharmacy (Teaching)
The primary focus of research in Dr. Jakowec’s laboratory is to better understand the underlying molecular mechanisms involved in neuroplasticity in the injured brain with the emphasis on the basal ganglia and prefrontal cortex, regions of the brain responsible for motor and cognitive behaviors.The overarching goal is to find improved therapeutic approaches for brain disorders especially Parkinson’s disease and drug addiction. For the past 20 years the laboratory has examined the effects of exercise on promoting neuroplasticity, particularly synaptogenesis in animal models of Parkinson’s disease. In addition to non-pharmacological approaches to promote brain repair, ongoing studies are using an experimental therapeutics approach to explore pharmacological interventions to determine if novel drugs can serve as a means to enhance brain repair, especially in the context of exercise. Recent studies have focused on the mechanisms by which astrocytes support neuronal function as well as mechanisms by which boosting mitochondrial integrity can promote improved functional connectivity and restoration of motor and cognitive behaviors.
Kanoski, Scott
Professor of Biological Sciences
The prevalence of obesity has exploded over the past 40 years. The biological systems that underlie the excessive eating behavior contributing to obesity onset remain poorly understood. Our research goal is to discover the neural systems and psychological processes that control energy balance, with a particular focus on understanding the neurobiological substrates that regulate obesity-promoting behaviors such as food impulsivity and environmental cue-induced feeding. Another primary focus of our lab is to study how the brain is negatively impacted by dietary and metabolic factors. Consumption of Western diets (high in saturated fatty acids and sugars) not only contributes to obesity development, but also produces deficits in learning and memory capabilities and can even increase the risk for developing dementia. We are currently examining the specific causal dietary factors, critical developmental periods, and neurobiological mechanisms underlying diet-induced cognitive decline. Ongoing research identifies the gut microbiome as a critical link between unhealthy junk food diets and neurocognition.
