Causal assumptions of the two-wave longitudinal mediation model
Published in Multivariate Behavioral Research, 2025
In this study, we aim to clearly define the specific causal effects estimated by each method within the two-wave longitudinal mediation model.

Statistical Evidence for Inequality: Applying Causal Restriction of Instrumental Variable
Published:
In this study, I suggested a new method to specify the existence of gender discrimination, using instrumental inequality. Causal graphical model was used to conceptualize the definition of gender discrimination.
Table 2 Fallacy in Latent Class Analysis
Published:
This talk is about the possibility of table 2 fallacy in latent class analysis when putting multiple predictors for latent class.
Credible Evidence of Gender Discrimination Using Instrumental Inequality

In this study, I suggested a new method to specify the existence of gender discrimination, using instrumental inequality. Causal graphical model was used to conceptualize the definition of gender discrimination.
Causal assumptions of the two-wave longitudinal mediation model
Published:
In this study, I analyzed causal assumptions required for both ANCOVA and change score method under two-wave longitudinal model.
Development and Validation of the Pre-service Teacher Competency Scale in an Online Learning Environment using the Scenario Method
Published:
This study uses the scenario method to develop and validate a scale measuring pre-service teacher competency in an online learning environment. After conducting a comprehensive literature review, this study constructed seven competencies of pre-service teacher in online learning environments: design/planning competency, social competency, instructive competency, technological competency, management competency, positive teacher attitude competency, and learning competency. We developed the Pre-service Teacher Competency in Online Learning Environment scale with 11 scenarios and 34 items after revising and improving it based on a focus group interview with six pre-service teachers and five in-service teachers to review face and content validity. We conducted confirmatory factor analyses and reliability analyses with 579 pre-service teachers. As a result, the scale showed good construct validity and reliability.
Graphical Criteria of Recoverability under Not Missing at Random Case
Published:
In this study, I suggested a causal graphical approach using m-DAG to check the possible bias in either in intercept and slope under the list-wise deletion situation. By doing so, this paper proposes general criteria for identifying which parameters are recoverable without bias under NMAR. Also, using m-DAGs with distinct notations for conditioning and controlling, this paper clarifies mechanisms behind bias in NMAR models. This approach allows researchers to assess recoverability of means and slopes (e.g., treatment effects), even under listwise deletion.

Afterschool math teacher
Middle school studet course, Samsung dream class, 2017
I taught impoverished middle school students math math for three years. Also, for their future career, I planned an individualized career development program. Link
Harvard Summer Student Research Program
Mentoring, Harvard University, 2024
I mentored an underprivileged hish school student to conduct a study using instrumental variable estimation. To do that, I provided lectures for causal inference, focusing on causal graphical model, and papers related to instrumental variable. Also, I guided the mentee to find and conduct her own research.

Causal Mediation
Mentoring, GESIS, 2024
I worked as a TA for the causal mediation workshop held by GESIS. As a TA, I helped students dealing with exercise in class using R, led the discussion and provided them relevent reading materials.
Quantitative Methods2
Teaching, Cornell, 2025
I gave a lecture on causal mediation analysis in a quantitative methods class, covering topics such as natural and controlled direct effects, as well as effect decomposition.
