My research interests lie in both empirical research and statistical model building of social and economic big data. On the empirical research side, my research has mainly focused on analyzing datasets primarily in finance and macroeconomics domain (financial markets, blockchain, news text, financial statements, firm networks, sales of products), but this does not mean that I am solely interested in economics. For the statistical modeling side, my focus is on developing models that take into account various characteristics and empirical regularities found in the economy and utilizing information from multiple sources in the form of a heterogeneous information network. For the latter model building research, I mainly develop network mining (simple, temporal, heterogeneous information network) and text mining methods. By combining the two research topics, my goal is to model complex issues in society (e.g., propagation and mitigation of shocks, hidden industrial block structure, aggregate fluctuation, matching among firms, network formation, bubbles, crashes, financial statements, systemic risks, the velocity of money, news events and reliability of information) to not only contribute to academic research but better understand risks and accelerate evidencebased policymaking.

I am studying fundamental aspects of complex and dynamical systems described by nonequilibrium statistical mechanics and nonlinear dynamics through mathematical modeling of specific systems in physics, engineering, and biology. The research subjects I have being working on include theory of thermodynamic efficiency of nonequilibrium heat engines, dynamical modeling of a lowtemperaturedifferential Stirling engine and elucidation of its rotational mechanism, and construction of energetics of synchronization in coupled oscillators.

Computations in biological neural networks, in particular linear and nonlinear analyses of largescale neuronal recordings.
My research aims at linking neural architectures to the underlying computations. To do so, I integrate experimental methods for alloptical dissection of neuronal circuits with largescale dynamical network models based on artificial neural networks (aNNs). The connectivity architecture of aNNs closely mirrors that of biological neural networks, thus representing an effective theoretical framework to unify computational, algorithmic, and implementation levels of analysis.

Computational Neuroscience, Theory of Neural Adaptation using Statistical Physics and Information Theory Tools
Our research is in the field of Computational Neuroscience. Computer models are used to study how information is processed in the brain and how the brain circuits adapt to and learn from the environment. We employ analytical techniques from statistical physics and information theory to investigate key functional properties for neuronal circuits. We use these techniques to reduce diverse experimental findings into a few core concepts that robustly explain the phenomena of interest. We are particularly interested in activitydependent forms of plasticity in the brain, which are known to have large impacts on learning, memory, and development. With the aid of mathematical models, we seek a theory that unites the cellular level plasticity rules and the circuit level adaptation in different brain areas and animal species. Efficacy of neurons to represent and retain information is estimated from the structure and behavior of resulting circuits.
