I am writing, testing and using simulation programs for precise particle and spin tracking in storage rings. The main applications for these programs are the proposed proton electric dipole moment (pEDM) experiment and the muon g-2 experiment. Both experiments are precision experiments and the use similar experimental techniques. The simulations are needed to test new concepts and to design the pEDM-ring.

I am studying about growth methods and electronic structures of high tc superconducting films using low temperature scanning tunneling microscopy (STM) with high magnetic field. I plan to grow high tc superconducting films under ultra high vacuum (UHV) and confirm the superconductivity of them using STM in situ. Based on the research results, I will try to develop superconducting cavities.

I have been interested in searching for anything beyond the standard model to understand what the Universe is. Now I am after the dark matter of the Universe by searching for axion. Then, the next after the dark matter will be the rest of the Universe.

Research interests:
- Trigger system design and construction for COMET experiment
- Trigger algorithm development for COMET experiment
- Signal processing electronics and DAQ system construction for CAPP Axion experiment
- Simulational efforts for Fermilab g-2 and BNL pEDM project
- Information
Broadly speaking, I am strongly interested in both aspects of the CAPP program, namely axion searches and the measurement of the proton electric dipole moment, together linked to the fundamental time reversal symmetry, ouside the traditional framework of the Standard Model of particle physics (what experts in the field call the Kobayashi-Maskawa framework). Axion searches, on the other hand, can have major cosmological consequences, whether or not an axion is discovered. Axions are in fact thought to provide most of the astronomical dark matter, which constitutes another great mistery in modern physics. My focus is currently on dark matter axion searches.

My research interests are:
Beam position monitoring
Beam profile monitoring
Spin and beam tracking
- Information
I am doing work on RF signal processing of the axion cavity experiment, focussing mainly on the room temperature signal processing. I am also interested in mythological aspects of modern physical cosmology.
- Information
My research interests lie in modern particle physics, focussing especially on the strong CP problem and one of its great candidate solutions, the axion.
Recently, I have started simulating the results of the spin-dependent interaction experiment motivated by Moody and Wilczek by the finite element method (FEM) software, OPERA.
- Information
I am working on a ground based telescope project called GroundBird to detectB-mode of the CMB polarization, which can be a smoking gun level discovery of the inflation model of our universe. The telescope is under construction in KEK/Japan. Our group is working on the focal plane optics, a small R&D on the superconducting film based resonator (MKID: Microwave Kinetic Inductance Detector) for the photon detection, and the readout electronics in the frequency domain. Till summer of 2015 is my sabbatical period at CAPP.

Functional Brain Mapping Lab
Introduction
Magnetic resonance imaging (MRI) is a very powerful non-invasive tool to visualize brain morphology, physiology, function and connectivity. However, MRI originates from water protons, thus its biological source is not straightforward. Especially, widely-used blood oxygenation-level dependent (BOLD) fMRI relies on the presumably close relationship between neural activity and hemodynamic responses. Therefore, it is crucial to understand underlying basis of fMRI for proper quantification and determining ultimate limits. Also MRI can image entire brain repeatedly from anesthetized to awake animals, and its readout can be combined with diverse manipulations such as sensory, electrical, chemical and optogenetic stimulation, and pharmacological interventions for answering system-level neural circuits. To obtain multimodal functional neuroimaging data, animal MRI facility (9.4 T and 15.2 T Bruker) is accompanied with a neurophysiology laboratory with electrophysiology, intrinsic optical imager, laser Doppler flowmeter, etc. Our research lab consisting of MR scientists and system neuroscientists focuses on three inter-related research themes; a) the development of physiological and functional MRI techniques, b) the investigation of biophysical and physiological sources of MRI signals (functional MRI, perfusion, diffusion, chemical exchange MRI), and c) the application of neuroimaging techniques to systems neuroscience research.

Lab Name: Neurovascular Coupling Laboratory
Introduction
Our laboratory aims to understand the basic mechanism of physiological interaction among neurons, glias and vascular system and provide better insights for perfusion related neuroimaging techniques. Our particular research interests include: 1) Study the effect of chronic stress on neurovascular coupling at functional and structural level, 2) Study the effect of pathologically heightened neuronal excitation and synchronization on neurovascular coupling at functional and structural level and develop cell-therapy for epilepsy, 3) Study neurovascular coupling mechanism through neurovascular coupling modulators, such as nitric oxide, carbon monoxide, & glucose, and 4) Develop novel techniques to restore neurovascular coupling dysfunction
