Research Interests
Dr. Mott is a Professor in the Department of Life Sciences, with research and teaching centered on environmental and public health microbiology, particularly coastal water quality issues. Her research currently focuses on recreational water quality, marine pathogens e.g. Vibrio vulnificus, and bacteria source tracking. The research laboratory, with funding through multiple grants, is very active and employs both graduate and undergraduate students. Two undergraduate students have been awarded American Society for Microbiology Undergraduate Fellowships under her mentorship. The lab is responsible for bacteria (enterococci) monitoring at 51 beach stations in the 4 local counties through the Texas Beach Watch Program, as well as examining sources of fecal indicator bacteria in several coastal water segments using a variety of current techniques. She frequently collaborates with other faculty on projects, for example on molecular characteristics of Vibrio vulnificus, mycorrhizal associations of coastal plants and microbial aspects of mariculture.
Current active projects:
- Recreational water quality assessment
- Bacteria source tracking for two coastal water segments
- Incidence and ecology of Vibrio vulnificus in south Texas coastal waters
- Antibiotic resistance profiling of environmental bacteria
- Fecal bacteria in sediments and agricultural land run-off
