Borner, Tito
Assistant Professor of Biological Sciences
The whole of his research career focuses on deepening our understanding of how nerve cells control food intake under both normal physiological conditions and when conditions go awry, such as when disease sets in. His overarching research goal is to investigate and identify the components and pathways within the central nervous system that mediate anorexia (loss of appetite), nausea, vomiting (emesis), and weight loss in pre-clinical models. This exploration focuses on understanding how these symptoms manifests after various diseases and, importantly, how they can be prevented, which special emphasis on chronic conditions such as cancer and diabetes.
Chang, Karen T.
Associate Professor of Physiology and Neuroscience
Our lab is interested in understanding how neurons communicate with high fidelity to support complex brain functions. We aim to uncover the molecular and cellular mechanisms that enable precise synaptic signaling and to explore how disruptions in these processes contribute to neurodevelopmental and neurodegenerative disorders. Using Drosophila melanogaster as a genetically tractable model system, we integrate electrophysiology, molecular biology, confocal imaging, proteomics, and behavioral analysis to investigate synaptic function and plasticity.
Dias, Brian George
Associate Professor of Developmental Neuroscience & Neurogenetics
Our research seeks to understand not only how mammalian neurobiology, physiology and reproductive biology is impacted by psychosocial and nutritional stress but also how parental legacies of such stressors influence offspring. To achieve this understanding, we employ a lifespan approach to study how stressors affect: sperm/egg/embryo (pre-conceptional stress), the gestating fetus (in utero stress), and the developing infant (post-natal stress). Our experimental approaches include assaying learning-memory-motivation, virus-mediated manipulation of neuronal activity and gene expression, (epi)genetic profiling of cells, in vivo fiber photometry and induced pluripotent stem cells (iPSCs).
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.
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.
Kay, Steve A.
Our laboratory studies the construction and dynamics of complex genetic networks that underlie circadian rhythms in humans, animals and plants. We also develop and use cutting-edge technologies for measuring transcription in live cells, tissues and intact organisms. We use large scale datasets of gene expression or protein content combined with genetics, bioinformatics and computational tools (mathematical modeling), chemical screens and more conventional biochemical approaches. Ultimately our aim is to scale our understanding of the dynamics of circadian clocks from the systems level down to atomic resolution mechanism. We have a strong commitment to translation of our research, in the case of humans for novel cancer drug discovery. We are currently focussing on targeting clock proteins in glioblastoma stem cells, in order to develop novel therapeutics.
