VISION: To make MRI more equitable and inclusive

MISSION: To develop and deploy MRI tools and methods to enable accessible imaging of underserved populations

Our mission is to reveal the molecular logic of our intelligence in health and disease. We use advanced molecular biological tools and state-of-the-art neuroscience to test the role of synaptic and neuronal molecules in the dynamics of the living brain.

Artificial neural networks have been heavily inspired by the brain’s architecture, guiding our journey to discovering the keys to intelligence. We now find ourselves at a pivotal moment: today's AI systems surpass biological circuits in certain tasks, yet we still lack a fundamental understanding of the mechanisms behind the brain’s superior cognitive flexibility and efficiency. At Ingie Hong’s Quantitative Intelligence Lab, we are dedicated to unraveling the principles that enable the mammalian cortex to achieve remarkable feats of intelligence, including rapid learning, generalization, and inference across vast stores of memory.

A single neuron’s response depends on its synaptic connections and intrinsic properties, which are dictated by the expression of neuronal genes. However, the role of these molecules in brain computations remains largely uncharted territory. Focusing on the mouse visual cortex as a starting point for broader generalization, and using large-scale electrophysiology, advanced microscopy, and machine learning, we have begun to uncover the impact of key synaptic genes on cortical processing and their role in the brain’s “working algorithm” (Hong et al., Nature, 2024). Our molecular tools, including gene therapy vectors and antisense oligonucleotides, show promise as effective therapeutic candidates.

Our research will advance the nascent field of 'neurocomputational therapeutics'—innovative genetic and pharmacological tools that address biases in neural activity. These tools will not only facilitate the development of novel mechanism-based treatments for brain disorders but also inspire the next generation of intelligent artificial neural networks.

Research in the Adam D. Sylvester Lab primarily focuses on the way in which humans and primates move through the environment, with the aim of reconstructing the locomotor repertoire of extinct hominins and other primates. We use a quantitative approach that involves the statistical analysis of three-dimensional biological shapes, specifically musculoskeletal structures, and then link the anatomy to function and function to locomotor behavior.

Researchers in the Adam Sapirstein Lab focus on the roles played by phospholipases A2 and their lipid metabolites in brain injury. Using in vivo and in vitro models of stroke and excitotoxicity, the team is examining the roles of the cytosolic, Group V, and Group X PLA2s as well as the function of PLA2s in cerebrovascular regulation. Investigators have discovered that cPLA2 is necessary for the early electrophysiologic changes that happen in hippocampal CA1 neurons after exposure to N-methyl-d-aspartate (NMDA). This finding has critical ramifications in terms of the possible uses of selective cPLA2 inhibitors after acute neurologic injuries.

Over the last few decades, a growing body of evidence has shown that the immune system is intimately connected with cardiac development, function and adaptation to injury. However, there is still much to learn and currently there are no immunomodulatory treatments to prevent or treat heart dysfunction. The Adamo Lab aims to study applied immunology in the context of cardiac function and dysfunction, to both elucidate fundamental properties of the immune systems and to develop novel therapeutic options for the rapidly growing number of patients living with heart disease.

Researchers in the Adrian Dobs Lab study topics that include gonadal dysfunction, hyperlipidemia, diabetes mellitus, and the relationship between sex hormones and heart disease. We currently are investigating male gonadal function—with particular interest in new forms of male hormone replacement therapy—and hormonal changes related to aging.

Our group is interested in the evaluation of basic pathophysiology in patients undergoing cardiac procedures, development and evaluation of new therapeutic strategies, and improving patient selection and outcomes following interventional procedures.

The Advanced Optics Lab uses innovative optical tools, including laser-based nanotechnologies, to understand cell motility and the regulation of cell shape. We pioneered laser-based nanotechnologies, including optical tweezers, nanotracking, and laser-tracking microrheology. Applications range from physics, pharmaceutical delivery by phagocytosis (cell and tissue engineering), bacterial pathogens important in human disease and cell division. Other projects in the lab are related to microscopy, specifically combining fluorescence and electron microscopy to view images of the subcellular structure around proteins.

The Agrawal Lab is focused on the medical and surgical treatment of otologic and neurotologic conditions. Research is focused on the vestibular system (the inner ear balance system), and how the function of the vestibular system changes with aging. Particular focus is given to study how age-related changes in vestibular function influence mobility disability and fall risk in older individuals.
