  SHORT BIOGRAPHY  

Youjin majored Genetic Engineering in Kyunghee University 2018 and joined Translational Genome Informatics Laboratory, Yonsei University on January 2018. She is studying happily more in depth of Bioinformatics with the attitude of scientist and working to develop useful algorithms that can be standardized and used universally in the community. She is especially interested in mosaicism and development of computational algorithms for its accurate detection.
