The unifying theme of the Lee lab is the elucidation of molecular mechanisms underlying genome/epigenome management using toolkits of biochemistry, chemical, and structural biology. In particular, we are interested in how DNA repair and epigenetic regulation maintain genomic and epigenomic integrity. Our current research interests include translesion DNA synthesis, DNA interstrand cross-links, and epigenetic regulation.
