Matthew K Waldor, M.D., Ph.D.

Other Positions

Available: 09/01/19, Expires: 08/31/23

The student will conduct a genome-wide screen to identify pathogen or host genes that contribute to pathogenesis of diseases caused by enteric pathogens. The student will be engaged in all steps of the project from creation of mutant libraries to analyses of the big data that screens generate. Some experience in molecular biology is preferable.

Available: 10/20/18, Expires: 09/30/23

Our lab studies the biology of Vibrio cholerae, the agent of cholera, and E. coli O157, a common cause of diarrheal disease in the USA. We are using a wide range of techniques to understand how these pathogens cause disease. We study both basic questions, such as how bacterial chromosomes replicate and segregate, and more applied issues such as development of new antibiotics and vaccines for diarrheal diseases.

PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
