Karol received his MS degree in Biotechnology from the University of Maria Curie-Sklodowska in Poland. His studies investigated interactions in the glioma microenvironment, conducted at the Nencki Institute of Experimental Biology in Warsaw. Later he spent one and a half years learning X-ray crystallography and cryo-EM techniques in the labs of Matthias Wilmanns (EMBL-Hamburg) and Venki Ramakrishnan (MRC-LMB). After that he pursued his PhD at MRC-MBU and IST Austria under the supervision of Leonid Sazanov. He defended his PhD thesis, "Cryo-EM studies of mammalian mitochondrial complex I," at the University of Cambridge, UK, in the summer of 2017, and joined the Chen Lab in November 2017.

Michael received his Bachelors degrees in Biochemistry (BS) and Biology (BA) at Indiana University. He pursued his Ph.D. from Vanderbilt University under the guidance of Dr. Marcia Newcomer, where he studied the structure and function of eicosanoid biosynthesis in soft coral. As a postdoc in the Chen Lab at Purdue, he determined the structure of the E. coli maltose transporter in several conformational states. At Rockefeller University, Michael plans to focus his study on eukaryotic ABC transporters.

Donna is a writer and freelance editor. Her previous professional experience includes managing the accreditation of continuing education for physicians and nurses at a non-profit healthcare organization.

Anna Tanasescu

Ana-Maria Tanasescu
Lab Coordinator
E-mail:atanasescu(at)rockefeller(dot)edu
212-327-7809

Ana-Maria received her B.S. in Medical Lab Science and Masters in Biology with Specialization in Biotechnology from Hunter College. She has previously done research in the Laboratory of Bacterial Pathogenesis and Immunology (Fischetti Lab) at Rockefeller University while she was an undergraduate student at Hunter College. There, under the close mentorship of Dr. Assaf Raz, she studied the bacteria which causes strep throat called Streptococcus pyogenes and performed a series of experiments in which inhibition of sortase by small-molecule inhibitors lead to rapid elimination of the bacterium. These inhibitors are possible anti-bacterial agents since they work by preventing the anchoring of virulence factors to the cell wall of the bacterium and reduce the pathogenicity of S. pyogenes. She joined the Chen Lab as a Research Assistant in 2016. Ana-Maria is currently the Lab Coordinator and Cell Culture guru.
