Sergei Mirkin

Sergei Mirkin (born September 29, 1956) is a Russian-American biologist who studies genome instability mediated by repetitive DNA during DNA replication and transcription.[1] He is a professor of Genetics and Molecular Biology and holds the White Family Chair in Biology at Tufts University.[2]

Early life and education

Mirkin was born in Moscow, Russia. He attended Moscow State University, where he earned both a Bachelor of Science and a Master of Science degree in Genetics in 1978.[2] Mirkin went on to pursue a PhD in Molecular Biology at the Russian Academy of Sciences’ Institute of Molecular Genetics.[3] His PhD was under the supervision of Roman B. Khesin, a molecular biologist and Mirkin later described his formative years in the Khesin lab in his essay, “Thinking of R.B. Khesin”.[4] By studying conditionally lethal mutants of  DNA gyrase, he established a fundamental interplay between DNA supercoiling and transcription in E. coli.[5]

Career and research

Mirkin conducted his postdoctoral studies at the Institute of Molecular Genetics with Maxim Frank-Kamenetskii, a biophysicist. This work culminated with the discovery of the three-stranded H-DNA structure.[6] Mirkin moved to the US as a Fogarty International Fellow in 1989 and joined the faculty of the Department of Genetics at University of Illinois Chicago (UIC) in 1990.[7] He worked at UIC until 2006 rising to the rank of Professor of Biochemistry and Molecular Genetics. In 2007, he joined Tufts University as a professor and the White Family Chair in Biology.[2]

Mirkin’s major contributions to science include discovering of the first multi-stranded DNA structure (H-DNA);[6] detection of dynamic non-B DNA structures, including DNA cruciforms and triplexes in vivo;[8] establishing that structure-prone DNA repeats stall DNA replication driving their expansions that are responsible for numerous hereditary diseases in humans;[9] and unraveling the mechanisms and consequences of transcription-replication collisions in vivo.[10]

The Mirkin lab continues studying genome structure and function from two perspectives: the mechanisms responsible for the instability of DNA repeats implicated in human disease, the role of transcription-replication collisions in genome instability and the mechanisms of genome instability mediated at interstitial telomeric sequences.[1]
