  • PEPS Graduate students Roshan Paudel, Lauren Braley, and Landon Wong along with Auburn U. grad student Claire Schloemer attended the Society of Nematologists Conference in Alaska. Together they competed in the Cobb Bowl (a nematode jeopardy game) as team “Aloha Nema” aka “Alohanema and won the Championship!

    The Champs
  • Graduate Student, Xupeng Wang, is using multiple molecualr tools from RT-PCR, cloning, high-throughput sequencing, Sanger sequencing to rapid amplification of complementary ends (RACE) to identify and characterize a new plant virus, Umbravirus, found on fig trees in Hawaii.

    New Discoveries
  • A graduate student, Adriana Larrea-Sarmiento, working in the Plant Virology Laboratory, is studying a new virus that causes large scale ginger dieback on ornamental ginger in Hawaii. Part of the study is also to investigate what insect is vectoring the virus which is important information for the control of the disease. Adriana is also developing a molecular detection assay for diagnostic use.

  • Graduate students in the Biosecurity Lab accompanied Mike Melzer to visit ornamental farms and diagnose a newly reported virus on ti leaf in Hawaiʻi.

Aloha! E Komo Mai!


  • MS Program
  • PhD Program

Master of Science in Tropical Plant Pathology

The MS degree program is offered under either Plan A (thesis) or Plan B (non-thesis). A total of 30 credit hours are required for each degree option. An advisory committee composed of at least three members of the graduate faculty provides guidance to the student. For a general description of these options, see the requirements for each option below.

The MS degree in tropical plant pathology provides a basic education and understanding of the pathogen groupings. Employment opportunities exist in industry, government agencies, research institutions, consulting, and farm management.

 

MS Plan A (Thesis)

Research: 12 credits in PEPS 700 Thesis Research, with at least 1 credit in PEPS 700 during the semester of graduation, and submission of an acceptable thesis.

Courses: 16 credits in courses approved by the candidate’s committee, including Core: PEPS 605, 606, 615, and  615L. and excluding PEPS 600, 699, 700, and 799.

Seminars: Minimum of 2 credits in PEPS 660, which is required each semester except when enrolled in PEPS 799; 2 credits in PEPS 799 (CR/NC). PEPS 799 credits are not counted towards degree credit requirements.

 

MS Plan B (Non-Thesis)

Research: 6-9 credits in PEPS 699 Directed Research, preferably taken in 2-3 different laboratories.

Courses: 19-22 credits in courses approved by the candidate’s committee, including Core courses: PEPS 605, 606. 615, and 615L. and excluding PEPS 660, 699, 700, and 799.

Seminars: Minimum of 2 credits in PEPS 660, which is required each semester except when enrolled in PEPS 799; 1 credit in PEPS 799 (CR/NC). PEPS 799 credits are not counted towards degree credit requirements.

PhD in Tropical Plant Pathology

Intended candidates for the PhD program should have earned the MS degree in plant pathology or equivalent from a recognized institution. Those with a BS or BA may petition for admittance into the PhD program only after enrolling in the MS program.

 

Employment options for PhD graduates are in teaching, research, and extension at universities and in research, consulting or management with private industries and government agencies.

 

Requirements:

No minimum course requirement. A candidate’s committee develops a course plan together with the student.

  • 1 credit hour of PEPS 660 each semester, except when enrolled in PEPS 799.
  • 2 credit hours of PEPS 799 Proposal/Defense Seminar (CR/NC).
  • Comprehensive and final defense examinations.
  • 1 credit hour of PEPS 800 Dissertation Research during semester of graduation.
  • Submission of acceptable dissertation.
