Research Summary
The research interests of the Lim lab lie in the broad field of bioinorganic chemistry as it interfaces with chemical biology, biochemistry, medicinal chemistry, and neuroscience. Our research objectives are to (a) identify the etiologies of human neurodegenerative disorders [particularly, elucidation of the roles of metals, proteins, and reactive oxygen species (ROS) individually or mutually in human neurodegenerative diseases]; (b) discover new, effective therapeutics for these diseases. These goals can be accomplished through designing small molecule-based or protein-based reagents (i) as chemical tools through understanding of the complicated networks between metals, various proteins and/or other molecules (i.e., neurotransmitters); (ii) as multi-tasking therapeutics. Students in our group have engaged in synthetic chemistry (organic and inorganic syntheses), physical methods (NMR, EPR, IR, CD, and UV-vis spectroscopy, mass spectrometry, and X-ray crystallography), as well as biological techniques (biological assays and mammalian cell culture/analysis).

임미희 교수의 실험실은 화학생물학, 생화학, 의약 화학, 신경 과학에 걸쳐 있는 넓은 분야에서의 생무기화학에 연구 관심사를 두고 있습니다. 이 실험실의 연구 목적은 (a) 인간 신경병성 질병의 원인(질병 내에서의 금속 이온, 단백질, 활성 산소의 개개인 또는 상호적인 역할)을 찾고, (b) 이러한 질병들에 대한 효과적인 치료법을 새롭게 개발하는 것입니다. 이 목표들은 저분자 또는 단백질에 기반을 둔 디자인한 화학도구를 도입하여 성공시키고자 합니다. 이들은 (i) 메탈과 여러 단백질, 혹은 신경 전달 물질과 같은 분자들 사이의 네트워크를 이해하는 데에 쓰일 수 있으며, (ii) 그 자체로 다기능을 가진 치료법에 적용될 수 있습니다. 임미희 교수 연구실의 학생들은 합성 화학(유기/무기 합성), 물리적 방법(NMR, EPR, IR, CD, UV-Vis 분광학, 질량 분석법, X-ray 결정학) 뿐만
아니라 생물학적 기법(생물 검정, 세포 배양/분석)에도 참여하고 있습니다.
