Biographical Information

Alla Kostyukova received her M.Sc. in Biophysics from St. Petersburg State University, Russia, and Ph.D. in Molecular Biology from the Institute of Protein Research, Russian Academy of Sciences & Moscow State University. She worked as a Research Associate in the Institute of Protein Research, Russia, and as a Senior Research Associate in RIKEN Harima Institute at SPring8, Japan, before moving to the USA. Before joining the Washington State University Voiland School faculty she worked for 4 years as an Assistant Professor and Director of the Circular Dichroism Facility in Robert Wood Johnson Medical School, Piscataway, NJ.

Research Interests

1. Regulation of actin dynamics in cytoskeleton of muscle and non-muscle cells. Playing a critical role in muscle contraction, cell movement, and cell morphology, actin filaments form vastly different structures in different cell types and different locations within the cell. Regulation of the dynamics at actin’s ends is of central importance in the assembly of these various structures. The major goal of our research is to determine the mechanisms of this fine-tuned regulation necessary to understand processes existent in living cells, such as myocytes and neurons.
2. Protein structure, protein-protein interactions and protein engineering. Important part of our research is studying structure of proteins and formation of protein complexes as well as engineering proteins with desired properties. These studies are parts in our ongoing projects as well as incollaborative projects.
