Prof. Alexei Savchenko led the lab for 10+ years until recently moving to the University of Calgary, where he remotely directs the lab.  Visit this page for more information on Prof. Savchenko’s lab at University of Calgary.


05cf311 Peter Stogios, Ph.D., Senior Research Associate p.stogios AT

Dr. Peter Stogios manages the day-to-day scientific affairs of the lab.  His main research interests lie in understanding the molecular basis of antibiotic resistance and antimicrobial drug discovery. As part of the Center for Structural Genomics of Infectious Diseases (CSGID,, this project involves structure-function studies of a variety of bacterial enzymes that are involved in mediating resistance to the actions of antimicrobials, with the goal of gaining insights into therapeutic intervention.
Peter’s roles are to coordinate target selection, 3D structure determination from x-ray diffraction data, analysis of protein 3D structures, design and implementation of biochemical follow-up, coordinating activities with collaborators and the greater biological community. Peter also performs maintenance of the lab’s x-ray diffraction facility, and training of staff and students in crystallography.

BZ_DiLeo Rosa Di Leo, M.Sc., Research Technician rosad AT

Rosa’s main responsibilities are to perform high-throughput cloning and expression/solubility testing for recombinant proteins in E. coli.

BZ_Evdokimova Elena Evdokimova, M.Sc., Research Technician el.evdokimova AT

Elena focuses on the expression, purification and crystallization of proteins for the determination of their 3-D structure by x-ray crystallography.  Her targets of interest include potential industrial enzymes, effector proteins of pathogenic bacteria and proteins responsible for antiobiotic resistance.




BZ_Skarina Tatiana Skarina, M.Sc., Research Technician tanskarina AT

Tatiana’s expertise lies in the optimization of protein crystallization, a key step in obtaining high quality 3D structures using x-ray crystallography.  Her work focuses on the use of crystallization techniques and functional assays to help characterize effector proteins.

BZ_Quaile Andrew (Andy) Quaile, Ph.D., Research Associate andrew.quaile AT

The remarkable abilities of bacterial effector protein’s to mimic, modulate and co-opt diverse and complex host cell pathways makes identifying their target interactors and functional complexes one of the big challenges that must be overcome in order to fully understand their biological roles. The majority of Andrew’s experience has been in the areas of proteomics and mass spectrometry, protein purification and identifying protein-protein and drug-protein interactions. His current research is focussed on identifying in-vitro functional partners of bacterial type 3 and 4 secretion system effectors using an affinity purification mass spectrometry (AP-MS) method.


BZ_Valleau Dylan Valleau, B.Sc., Ph.D. Candidate dylan.valleau AT

Dylan’s research aims to elucidate how gram-negative bacterial pathogens are able to colonize their host through the injection of effector proteins into host cells. One of the primary targets of bacterial pathogens appears to be the host ubiquitin proteasome system (UPS), which orchestrates the posttranslational modification of target proteins, resulting in the covalent attachment of a small protein, ubiquitin, typically signaling for degradation of the target protein. The most common function hijacked by bacterial effectors is that of eukaryotic protein ubiquitin ligases (also known as E3 enzymes), which directly catalyze the addition of ubiquitin to targets. Dylan’s task is to characterize the role of E3 ligase effectors from pathogenic E. coli, Salmonella, and Shigella, through a combination of in vitro and in vivo techniques, including co-immunoprecipitation and mass spectrometry, structural characterization, and expression analysis in human cell lines.
