About the Lab
Professor Euitae Kim's research lab specializes in molecular imaging and pharmacokinetic-pharmacodynamic (PK-PD) modeling to investigate the neurobiological mechanisms of psychiatric disorders, particularly schizophrenia. The lab focuses on using positron emission tomography (PET) to quantify neurotransmitter systems—especially dopamine D2/3 receptors—and to study the relationship between antipsychotic drug exposure, receptor occupancy, and clinical outcomes. Key research directions include optimizing PET image analysis techniques such as partial volume correction and developing translational biomarkers to assess treatment response and cognitive function. The lab also investigates early intervention strategies, particularly in ultra-high-risk populations, to improve long-term outcomes in psychosis.

15Positron emission tomography (PET) studies of dopamine receptor occupancy can be used to assess dosing of antipsychotics. Typically, studies of antipsychotics have applied pharmacodynamic (PD) modeling alone to characterize the relationship between antipsychotic dose and its effect on the brain. However, a limitation of this approach is that it does not account for the discrepancy between the time courses of plasma concentration and receptor occupancy by antipsychotics. Combined pharmacokinetic-
Abstract Aripiprazole’s effects on cognitive function in patients with schizophrenia are unclear because of the difficulty in disentangling specific effects on cognitive function from secondary effects due to the improvement in other schizophrenic symptoms. One approach to address this is to use an intermediate biomarker to investigate the relationship between the drug’s effect on the brain and change in cognitive function. This study aims to investigate aripiprazole’s effect on working memory b
Starting paliperidone LAI significantly improved clinical and functional outcomes in patients with schizophrenia, especially those with shorter duration of illness. These findings suggest that LAI antipsychotic administration may be considered in early-stage schizophrenia for improved outcomes.
We validated the use of a novel image-based method for partial volume correction (PVC), structural-functional synergistic resolution recovery (SFS-RR) for the accurate quantification of dopamine synthesis capacity measured using [(18)F]DOPA positron emission tomography. The bias and reliability of SFS-RR were compared with the geometric transfer matrix (GTM) method. Both methodologies were applied to the parametric maps of [(18)F]DOPA utilization rates (ki(cer)). Validation was first performed b
Molecular imaging techniques have a number of advantages for research into the pathophysiology and treatment of central nervous system (CNS) disorders. Firstly, they provide a noninvasive means of characterizing physiological processes in the living brain, enabling molecular alterations to be linked to clinical changes. Secondly, the pathophysiological target in a given CNS disorder can be measured in animal models and in experimental human models in the same way, which enables translational res
AIM: To explore the differences in pharmacotherapy and clinical characteristics of individuals at ultra-high-risk (UHR) for psychosis according to the conversion status, we analyzed the data for UHR patients seen at the Seoul Youth Clinic. METHODS: This was a naturalistic observational study. We obtained clinical data, including demographic data, presenting complaint, duration of psychiatric symptoms, diagnosis and scores on clinical rating scales from individual records in the Seoul Youth Clini
BACKGROUND: Given that only a subgroup of patients with schizophrenia responds to first-line antipsychotic drugs, a key clinical question is what underlies treatment response. Observations that prefrontal activity correlates with striatal dopaminergic function, have led to the hypothesis that disrupted frontostriatal functional connectivity (FC) could be associated with altered dopaminergic function. Thus, the aim of this study was to investigate the relationship between frontostriatal FC and st
노숙인은 자신의 삶을 변화시키기 위한 장기적이고 체계적인 교육기회를 얻기가 어렵다. 이런 점에서 평생교육의 장에서 진행되고 있는 노숙인 대상 인문교양교육은 응급 구호와 물질적 차원의 일시적 지원과 달리 자존감 회복과 자기성찰을 통해 자립할 수 있는 근원적인 힘을 확보하는 통로라 할 수 있다. 이 연구에서는 노숙인이 인간으로서의 존엄성과 가치를 회복하고 장기적으로 삶의 방향을 재설정하는 계기로서 인문교양교육이 어떻게 작동하는지를 살펴보기 위해 대한성공회 노숙인다시서기지원센터가 운영하고 있는 <성프란시스대학 인문학과정>을 사례로 삼았다. 이 사례를 통해 노숙인을 성인 학습자로 간주하는 프로그램의 구조와 특성을 제시하고, 실제 프로그램 참여 노숙인의 학습경험이 어떤 양상으로 전개되었는지를 제시했다. 노숙인은 참여과정에서 ‘경계'에 서있는 학습자로서 경제적 어려움과 현실과의 괴리감 등으로 내적 갈등을 겪기도 했지만, 대화와 토론, 글쓰기 경험을 통해 자신의 생애경험과 맞물려 인문학적 질문들
The aim of the present study was to evaluate the effects of polymorphisms in dopamine D2 receptor (DRD2) and cytochrome P450 (CYP) 2D6 genes on delta EEG power response to aripiprazole in healthy male volunteers. Seventeen volunteers were recruited according to the DRD2 Taq1A genotype, and separated into the following groups: homozygous wild-type (A2/A2, n = 7), heterozygous (A2/A1, n = 5) and homozygous variant-type (A1/A1, n = 5) groups. After enrollment in this study, they were genotyped for
