Milka Kostic, Ph.D.
Scientific Editor

Milka obtained her Ph.D. in Chemistry from Brandeis University in Waltham, MA, USA. Her Ph.D. research was focused on biomolecular nuclear magnetic resonance (NMR) spectroscopy and developing new NMR methods to study metalloproteins, especially those involved in electron transfer chains such as ferredoxins. Her postdoctoral work in the Department of Molecular Biology at The Scripps Research Institute, La Jolla, CA, USA applied NMR spectroscopy and other biochemical and biophysical methods of protein characterization to address different aspects of tumor suppressor p53 biology by working on Mdm2, an E3 ligase that regulate p53 levels, and Hsp90, a molecular chaperone that stabilizes p53. After completing her postdoctoral work, she joined Cell Press and served as the Editor of Structure and Cell Chemical Biology (previously published as Chemistry & Biology) for a decade. Currently, she is the Program Director, Chemical Biology at the Dana-Farber Cancer Institute where she spends her time bringing strategy, cohesion, and mentoring to support approximately 120 researchers. She joined Life Science Editors as an Editor in 2019.
