I am an assistant professor of surgery and population health at NYU Grossman School of Medicine.
I mainly work on 3 research areas:
I analyze clinical data to improve decision-making in chronic kidney disease and kidney transplantation.
I develop methods to find the best-fitting drug based on the individual patient's characteristics (heterogeneous treatment effect) and to distill the "truth" from the data in hand (causal inference).
I use artificial intelligence to better solve these problems.
I received my PhD, MHS, and MPH at Johns Hopkins Bloomberg School of Public Health. Before Hopkins, I received a KMD at Kyung Hee University and saw patients, mostly at Mokpo National Hospital [Korean].

I used to take landscape photos. This hobby turned into portraits when my kid was born.

[Am J Transplant, 2018] Who Can Tolerate a Marginal Kidney? Predicting Survival After Deceased-Donor Kidney Transplantation by Donor-Recipient Combination.
In kidney transplantation (KT), both donor quality and recipient health condition are key determinants of survival after KT. Understanding the interaction between the two factors can improve donor-recipient matching. We estimated post-KT survival using random forests, a machine learning algorithm that can reflect complex interactions between predictors with minimal assumptions. Also check out our online tool!
[Am J Transplant, 2016] Changes in discard rate after the introduction of the Kidney Donor Profile Index (KDPI).
We assessed how providing a numeric risk score of donor health conditions influenced clinical practice in kidney transplantation using a national dataset (n=57657). Our findings suggest an adverse “labeling effect” of the score: in other words, the improved risk index might have prompted clinicians to be more risk-averse.
