Alexander Serganov

Principal Investigator

Alexander Serganov joined the Department of Biochemistry and Molecular Pharmacology of NYU School of Medicine in May 2011. He graduated from the Moscow State University with a B.Sc. degree in Molecular Biology. During his Ph.D. studies he split his time between the Maria Garber laboratory at the Institute of Protein Research of the Russian Academy of Sciences (Pushchino, Russia), the Bernard Ehresmann laboratory at the Institute of Molecular and Cellular Biology (Strasbourg, France), and the Claude Portier laboratory at the Institute of Physico-Chemical Biology (Paris, France). His Ph.D. work focused on the regulation of gene expression during ribosome biogenesis. He continued his studies as a postdoc in the Ehresmann laboratory. He then joined Dinshaw J. Patel’s laboratory at Memorial Sloan Kettering Cancer Center (New York, USA) to study molecular mechanisms of RNA-mediated catalysis and gene expression control. He championed several seminal projects including the first three-dimensional structures of the non-coding regulatory RNA elements termed riboswitches and the first structure of a ribozyme catalyzing a synthetic reaction.

Nikita Vasilyev

Postdoctoral Fellow

Nikita Vasilyev received a M.Sc. degree in Biology from the Moscow State University. He performed his Ph.D. work on the structure and function of viral RNA polymerase in the Alexander Chetverin laboratory at the Institute of Protein Research of the Russian Academy of Sciences (Pushchino, Russia). His current research focuses on RNA-protein complexes associated with RNA degradation and neurological diseases. He also pursues studies of bacterial RNA polymerase.

Ang Gao

Postdoctoral Fellow

Ang Gao received a M.Sc. in Microbiology from Shandong University. She carried out her Ph.D. research on the structure and catalysis of enzymes associated with bacterial quorum sensing in the laboratory of Dongcai Liang at the Institute of Biophysics of the Chinese Academy of Sciences (Beijing, China). She currently conducts studies on non-coding RNAs as well as degradation and post-transcriptional modification of mRNA in bacteria and eukaryotes.

Alla Peselis

Graduate Student

Alla Peselis received a M.Sc. in Cell and Molecular Biology from the University of Rhode Island. She joined the Serganov laboratory as a technician to work on the structure and function of riboswitches. Shortly thereafter she decided to pursue a Ph.D. on the study of the long non-coding RNA Rmrp involved in the activation of the inflammatory response in lymphocytes.
