    Introdution

    Our lab focuses on developing novel data processing algorithms for neuroimaging. We are particularly interested in image registration, segmentation, and feature extraction for various medical imaging modalities. Neuroimaging data contain millions of voxels and thus robust algorithmic considerations are required to properly explore such high-dimensional data. We are witnessing exponential growth in accumulated data with advances in neuroimaging technology. Thus, the role of data post-processing will be an integral part of advanced neuroimaging research. We also have following research interests; 1) data mining for neuroimaging, 2) medical image analysis for age modeling and neurological disease, 3) medical image analysis for cancer management.

    Introduction


    The goal of our research is to understand how the human brain gives rise to perception and cognition, and specifically how top-down or feedback processing contributes to this process. Research focuses on how top-down processing serves to gate the entry of information into attention and memory, alter fundamental information about object location and identity, create new representations at early stages of processing where no feedforward information exists, and integrate information from multiple sensory modalities. In order to gain a comprehensive understanding of the cognitive and neural mechanisms that underlie human mental processes, including perception, attention, and memory we combine techniques from neuroimaging (encoding and decoding), vision sciences, and cognitive psychology. This allows us to explore how the brain represents and processes a range of perceptual and cognitive information.

    Introduction


    The mission of our lab is to understand pain and emotions in the perspective of Computational, Cognitive, and Affective Neuroscience. We also aim to develop clinically useful neuroimaging models and tools that can be used and shared across different research groups and clinical settings.


    Our main research tools include functional Magnetic Resonance Imaging (fMRI), psychophysiology measures (skin conductance, pupilometry, electrocardiogram, respiration), electroencephalogram (EEG), and other behavioral measures such as face recording camera, eye-tracker, etc. Most importantly, we use computational tools to model and understand our affective, cognitive, and behavioral responses.

    High-resolution fMRI Lab


    Introduction


    My lab is developing acquisition and analysis methods for high-resolution fMRI in humans. In particular, we are trying to image mesoscopic human brain function using MRI at 7 Tesla. To that end, novel fMRI sequences are developed and tested, analysis pipeline developed, and physiological model of ascending vein effects are applied to the data to remove spatial bias in the fMRI signal. In addition, we are interested in quantitative MRI approaches at 7 Tesla to study subcortical brain organization and cortical brain parcellation in both healthy subjects and patients. Finally, the lab pursues modeling brain connectivity using physiological principles and advanced computational approaches.
