I’m interested in studying the neural mechanisms underlying the formation and retrieval of episodic memory. During my PhD at Seoul National University in Korea, I investigated the neural dynamics of hippocampal subregions (CA1, CA3, and subiculum) in response to changes in visual stimuli. After my PhD, I moved to the US and joined the Heys lab as a postdoc. Now, I am studying how neural activity in the medial entorhinal cortex mediates the learning of timing behavior using in vivo physiology techniques in mice. Outside of the lab, I enjoy paddleboarding and gardening.

I am a behavioral neuroscientist interested in how emotional experiences shape memory and social behavior. During my PhD in South Korea, I studied how different types of fear memories are processed and modulated within amygdala-related circuits. This work sparked my interest in how stress and emotional states influence brain function and behavior more broadly. Currently, as a postdoctoral researcher in the Zelikowsky lab, I investigate how social factors modulate behavior in female rodents, with a focus on identifying circuit and behavioral signatures of partner stress. Outside of the lab, I enjoy spending time with friends, playing video games, and walking in nature.

Research in the Heys Lab is aimed towards uncovering the synaptic, cellular and circuit level mechanisms that underlie the formation and recall of episodic memory. Furthermore, we aim to understand how these mechanisms become disrupted in disease. We leverage cutting-edge optical imaging and electrophysiological techniques designed for application in awake-behaving rodents that enable recording and manipulation of neural physiology - from the level​ of individual synaptic spines up to thousands of simultaneously monitored neurons. These techniques are used in combination with virtual reality paradigms in order to carefully monitor and control animal behavior. Our experimental questions and approach are developed in concert with theoretical and computational models of behavior and neural circuit dynamics.
