SALAVATI LAB RESEARCH

The three related species of trypanosomatids, Trypanosoma brucei, Trypanosoma cruzi, and Leishmania major, cause serious human and animal diseases, with a very high incidence and mortality rate if left untreated. There are no vaccines for these pathogens, the drugs are toxic with limited effectiveness, and drug resistance is emerging. The availability of the genome sequences of these organisms since 2005 has dramatically expanded our knowledge of their biology; however, a major obstacle has since been acknowledged: the majority of trypanosomatid genes are not found in any other organism, making it almost impossible to use homology-based methods for inferring their functions from their sequences.


Our lab is focused on the development of novel computational and experimental methods for functional and structural characterization of trypanosomatid genomes. We are also involved in the development of high-throughput methods for identification of novel chemical inhibitors of essential trypanosomatid proteins, particularly the editing complex of T. brucei. Functional characterization of some of the key trypanosomatid proteins that are involved in RNA editing is also among the major research topics of our lab.

Systems analysis of trypanosomatid genomes

Our lab is focused on the development of novel computational and experimental methods for the functional and structural characterization of trypanosomatid genomes. We use systems biology of trypanosomatid pathogens to identify key genes / pathways and determine their function.

Dynamics and developmental regulation of the editosome function in trypanosomatids

Another major research topic in our lab is the functional characterization of key trypanosomatid proteins that are involved in post-transcriptional gene regulation.

Targeting the essential pathways in trypanosomatids for drug discovery

We are involved in the development of high-throughput methods for the identification of novel chemical inhibitors of essential trypanosomatid proteins. We have identified potential inhibitors for RNA editing that kill T. brucei in vitro with a proposed mechanism of inhibition.

AVAILABLE POSITIONS

Positions are available for highly motivated post-doctoral fellows and students who are interested in a master's and doctoral thesis to study molecular parasitology in a multidisciplinary environment.

Please fill out the application form to apply to the lab. If there is an position available and your application is considered a good fit for the lab, then we will contact you about arranging an interview and a chance to meet the other members of the lab. If you do not hear from us before any application deadlines it means that there was not a position in the lab that was suitable for you.

Please be sure to specify your area of interest in the application form. To learn more, please have a look at our current research projects and publications.

Please note that we are deeply committed to enacting plans at Salavati Lab to help reduce systemic bias problems, prevent discrimination, and improve inclusivity. As such, EDI will be a component of the selection process when we are considering applicants to the lab.

Equity, Diversity, & Inclusion



EDI Statement


At the Salavati Lab, we strive to make scientific academia an equitable, diverse, and inclusive space. If you have any questions or sugestions on how we can improve, do not hesistate to share your thoughts with us.

Land Acknowledgement


Located on lands where Indigenous peoples, including the Haudenosaunee and Anishinabeg nations have met, McGill honours and respects these nations as the traditional stewards of the lands we use.

Mission Statement


Beyond our mission towards research and training, EDI carries a special significance in the context of Global Infectious Diseases (GID) that affect large populations globally and cause numerous deaths.

GID affects marginalized and racialized individuals and communities with limited access to prevention and disease control methods with heightened social and health consequences. As a group, we strive to mitigate these global health disparities.

Significance


We firmly believe that the values of equity, diversity, and inclusion are fundamental to a healthy work environment and promote individual well-being.

Diverse environments bring together unique perspectives that promote creativity, stimulating discussions, and open-mindedness.

Scientific progress thrives when individuals of different backgrounds are brought together to take on difficult questions.

Implications


Salavati Lab is aware that discrimination can be based on a number of factors including race, gender, sexual orientation, religion, disability, and many more.

We recognize that disparities in opportunities (such as, but not limited to: socioeconomic status, familial connections, familial responsibilities, access to resources) can result in differences that are not related to one’s potential to be a valued member of the lab.

Thus, we are committed to understanding and removing such biases within the lab. With this in mind, our application form is designed with the intention of allowing for fairer candidate selection process.

We acknowledge that this is always a work in progress and we welcome further discussions for how we can improve. Please do not hesitate to reach out to us.
