• Sunil Kim completed both his undergraduate and master's studies at the Department of Physics at Konkuk University in Seoul. During the time, he engaged in statistical mechanical investigations of electron dynamics in complex mediums.
• Currently, he is pursuing his doctoral studies under the guidance of Professor Jaeseung Jeong at the Department of Brain and Cognitive Sciences at KAIST. His research primarily involves the analysis of biosignals such as EEG and EMG through the application of non-linear dynamics techniques.
• More specifically, his work utilizes data-driven science algorithms, such as the Sparse Identification of Nonlinear Dynamics (SINDy), to discover a set of differential equations that can aptly describe given biosignals. His research aims to interpret these equations in a dimension that has physiological significance.
• Through this analytical approach, he aspires to offer physiological or physical interpretability to currently employed "black box" AI models.
• His grand vision, rooted in this newfound interpretability, is to elucidate a General Theory of Brain Dynamics, a breakthrough that could fundamentally transform our understanding of the brain's inner workings.

Biosketch

• I graduated from KAIST with a major in Bio and Brain Engineering and am now pursuing a Ph.D. under the supervision of Professor Jaeseung Jung. The primary area of focus for me is connectome, a comprehensive cartography of neural connections within an organism's brain or nervous system. This map provides a detailed blueprint of the neural architecture, facilitating the study of brain function and information processing. In my studies, I am particularly interested in the structural asymmetry of the Caenorhabditis elegans connectome and how it connects to functional asymmetry. My objective is to identify network properties that can enhance our understanding of asymmetry, with potential implications for the connectome of complex organisms, including humans.

Biosketch

• I completed my bachelor, and master's degrees at the KAIST Department of Bio and Brain Engineering, where I was introduced to the world of Neuroscience. During this period I focused on cognitive neuroscience, and related opportunities for machine learning applications, such as in the field of computational neuropsychiatry. As a member of Professor Jaeseung Jeong's decision-brain dynamics lab, my attention is centered on the neural mechanisms underlying social curiosity, and its influences on learning, interaction, perception, and decision-making in the social domain. I believe that this knowledge can potentially be leveraged to address the social impairments prevalent in numerous mental disorders, ultimately enhancing the lives of those affected. I also remain deeply interested in the application of machine learning techniques toward a better understanding and early diagnosis of mental disorders and impaired cognitive functioning. Through my research, I aim to contribute to improving the quality of life for individuals navigating the complexities of cognitive and social impairments.

• By acquiring her Bachelor’s degree in Biology and Genetics, Yulia has shaped her academic interests in the peculiarities of human cognitive function and the neural mechanisms underlying the most perplexing processes such as economic decision-making including the most relevant cognitive biases expressed in human choice behaviours. At the prof. Jaeseung Jeong’s Brain Dynamics lab, she aims to focus her research on the neural substrates of the intertemporal choice intererwined with risk preference and ambiguity aversion - the idea of correlation proposed in various behavioural economic models. Studying economic decision making is crucial in terms of human behavior because it helps us understand how individuals make choices, allocate resources, respond to incentives, and pursue their goals, providing valuable insights into decision-making processes that can be applied to various domains beyond economics, such as psychology, sociology, and public policy.
