Arnold, Don
Professor of Biological Sciences
The Arnold lab develops molecular tools for studying and manipulating neural circuits. We have developed novel recombinant probes known as FingRs, which label synaptic proteins such as PSD95, Gephyrin, and CamKii with high fidelity without causing off-target effects. We have used FingRs to visualize the formation of memories in larval zebrafish. These probes can also be used to ablate synapses, leading to functional disruption of neural circuits in a fast, efficient, and reversible manner. More recently, we developed ATLAS, a protein that mediates anterograde tracing of neural circuits from genetically determined neurons. We believe that ATLAS and its variants for tracing neuromodulatory circuits will be powerful tools for observing and manipulating neural circuits in the context of living organisms.
Bienkowski, Michael
Assistant Professor of Physiology and Neuroscience and Biomedical Engineering
Our lab investigates brain cell types, their susceptibility to disease, and how biomedical treatments can slow or prevent neurodegeneration. We have a wide variety of collaborative research projects using animal models of retinal diseases and Alzheimer’s disease (mice, rats, rabbits) as well as studies in post-mortem human samples. We use cutting-edge multidisciplinary approaches to characterize brain cell types and their neurodegeneration including viral tract tracing connectomics, spatial transcriptomics, 3D neuronal reconstruction, and digital pathology/machine learning.
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.
Bottjer, Sarah
Professor of Biological Sciences and Psychology
Our lab studies how neural circuits that traverse the cortex and basal ganglia mediate motor skill learning during development. Skill learning entails the acquisition of a new behavior as trial and error of variable actions are refined into a stereotyped pattern. Acquisition of new motor skills depends on neural circuits that compare feedback of self-generated movements to a desired goal and reinforce “correct" movements that match that goal. We use multidisciplinary behavioral and systems neuroscience approaches to study the function of cortico-basal ganglia circuits during developmental skill learning. Understanding the normal function of these circuits is a necessary prerequisite to understanding the multiple diseases associated with disorders of the basal ganglia.
Ching, Christopher
Assistant Professor Of Research Neurology
Dr. Ching’s research focuses on neuroimaging and genomic markers of psychiatric and neurodegenerative disorders. As a core organizing member of the Enhancing Neuro Imaging Genetics through Meta-Analysis (ENIGMA) Consortium, he designs and implements standardized processing and analysis techniques for large-scale neuroimaging studies. He leads the ENIGMA Bipolar Disorder Working Group, an effort pooling data and resources from around the world to improve our understanding of the biological processes driving bipolar disorder, and studies rare copy number variants like 22q11.2 Deletion Syndrome to understand how genetic mutations can lead to increased risk for developing psychiatric illness. He leads several large-scale transdiagnostic neuroimaging and genomic initiatives using machine learning to map common and distinct brain and clinical factors across mental illnesses.
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).
