Microbiology and Environmental Toxicology

Graduate training in the METX Department prepares students to solve important problems in the field of environmental health by providing stimulating coursework, extensive scientific presentation training, and in-depth research that culminates in a thesis. There is no other program in the world that educates students to appreciate the interplay between microbes, chemical toxins, and health and provides the training students require to work effectively in a complex world. Graduate training in the METX department prepares students to become leaders in the field, following career paths in academia, teaching, industry, and government. Master of Science (M.S.) students typically finish in two years and Doctor of Philosophy (Ph.D.) students in four to six years.

Key components of our graduate training include:

• Interdisciplinary core course that teaches critical thinking and how to approach problems: METX 200, Interdisciplinary Approaches to Problems at the Interface of Microbiology and Environmental Toxicology.

• Core course devoted to grant-writing skills: METX 205, Scientific Skills, Ethics, and Writing.

• Personalized class plan for the remaining three courses to fit the student’s background and research goals. Possible courses include METX 201, Sources and Fates of Pollutants, METX 202, Cell and Molecular Toxicology, METX 206A, Advanced Microbiology, METX 210, Molecular and Cellular Basis of Bacterial Pathogenesis, METX 238, Pathogenesis: Molecular Mechanisms of Disease, and METX 250, Environmental Microbiology, as well as courses in other departments such as Ocean Sciences 220, Chemical Oceanography, and Molecular Cell and Developmental Biology 200B, Advanced Molecular Genetics. Speaking presentation skills training through coursework and yearly departmental presentations. Scientific writing and literature mastery through the writing of a literature review in the first year. Weekly seminars expose students to the breadth of our fields and provide students with opportunities to interact closely with speakers to form connections and collaborations.

• Qualifying examinations designed to perfect the student’s ability to craft research plans.

• Extensive laboratory research training that starts immediately upon entering the program and culminates in the student’s master’s thesis or Ph.D. dissertation.

Sample Pathways

Pathways within the microbiology and environmental toxicology graduate program focus on interdisciplinary approaches to addressing problems in environmental and public health.  We offer several defined training pathways, and also encourage students to create their own.

Metals in the Environment

Research includes how organisms are exposed to metals, how these metals cause toxicity, and investigating the concentration, speciation, and isotopic composition of contaminant metals and metalloids.

Microbiology

Microbiology provides research training on molecular genetic analysis of both non-pathogenic and pathogenic microbes. Students study host-pathogen interactions, ecology and evolution of pathogenic microorganisms, adaptation of pathogenic and non-pathogenic microorganisms to environmental stresses, and mechanisms of microbial biotransformation of pollutants and toxic metals.

Cellular and Organismal Toxicology

This pathway provides training in the biochemical, molecular, cellular, and physiological processes that are impacted by exposures to such contaminants as toxic metals. Research includes exposure pathways and toxicity of contaminants and pathogens within humans, with emphasis on the molecular and cellular mechanisms underlying toxicity.

Microbial Biology and Pathogenesis track within the Program in Biomedical Sciences and Engineering (PBSE)

The METX Department also admits students through the PBSE program Microbial Biology and Pathogenesis (MICRO) Ph.D. track. PBSE track is a rotation-based graduate umbrella program. This training program emphasizes the application of diverse approaches, including biochemistry, genetics, genomics, ecology, and imaging to address questions at the forefront of microbial biology. Interdisciplinary research is encouraged and supported by a diverse group of faculty from the METX Department as well as from the Departments of Biomolecular Engineering; Ocean Sciences; Molecular, Cell, and Developmental Biology; Evolutionary and Ecology Biology; and Chemistry and Biochemistry.

Fifth-Year M.S. path

METX offers a fifth-year master of science (M.S.) degree path when earned contiguous with an appropriate Bachelor of Science (B.S.) degree at UCSC. The fifth-year M.S. path provides highly motivated undergraduate majors the opportunity to earn separate B.S. and M.S. degrees in five years. The path provides the additional level of preparation and experience that students need to pursue careers in industry, government, or to increase their competitiveness for top Ph.D. programs. Students apply to be accepted into the fifth-year M.S. path in consultation with their faculty or undergraduate adviser, no later than the end of the spring quarter of the junior year.

To be accepted to the path, students will need to prepare an application and plan for their fifth-year BS/MS, providing evidence of solid academic performance in general and in their undergraduate major. The application should be submitted no later than end spring quarter of the junior year, and should include:

• A one-page personal statement describing a) the student’s motivation and academic preparation for entering the path; b) the student’s goals for the fifth-year path, including the area of concentration; c) the name of a faculty member willing to serve as their thesis adviser (if appropriate); and d) future professional goals.
• Copy of unofficial transcripts establishing the GPA requirements in the undergraduate major and overall. Applicants should possess a GPA in courses of their undergraduate major (biology, chemistry, etc.) of 3.2 or above, and an overall GPA of 3.0 or above.
• A letter of recommendation from the METX faculty member attesting to the student’s promise for a M.S. degree in METX.
• A coursework plan that will enable them to complete both the requirements for the B.S. in their undergraduate department and M.S. in METX in five years, including demonstrating sufficient coursework capacity to complete at least one to two METX graduate courses in  their final undergraduate year.

If accepted into the fifth-year B.S./M.S. path, students will go through the regular METX M.S. application process early in their senior year. The criteria for admission to the METX M.S. program  will be the same as for all METX M.S. program applicants.

Program Requirements

The METX student’s curriculum is tailored to the individual, creating a graduate experience that combines essential background material with coursework at the frontiers of science. The student, in conjunction with a faculty committee, chooses classes to complement the Ph.D. or master’s thesis work that each student is performing. Students are encouraged to explore new areas and bring this expertise back to their thesis research.

Requirements for both Master’s and Ph.D. Students in Microbiology and Environmental Toxicology

1. Core coursework. METX 200 Interdisciplinary Approaches to Problems at the Interface of Microbiology and Environmental Toxicology, and METX 205, Scientific Skills, Ethics, and Writing, must be taken and passed with at least a B.
