Day In The Life

Professor Emeritus of Plant Pathology

I am a retired plant pathologist that developed the Rainbow, a GMO papaya resistant to viruses.

My Day to Day

I investigate plant diseases and I specialize in identifying and treating plant viruses.

Skills & Education

Advice for getting started

You have to remember your motive for why you are doing something and always try to do something that will help others.

Here's the path I took:

  • High School

  • Bachelor's Degree

    Horticultural Science

    University of Hawaii at Manoa

  • Graduate Degree

    Plant Pathology/Phytopathology

    University of Hawaii at Manoa

  • Doctorate

    Plant Pathology/Phytopathology

    University of California-Davis

Life & Career Milestones

My path in life took a while to figure out

  • 1.

    After earning his bachelor’s degree in horticulture from the University of Hawaii, he originally just wanted to find a job.

  • 2.

    He was hired as a technician on Kauaʻi, and his boss showed him a virus he suspected was developing on the papaya plants.

  • 3.

    With no preparation—aside from one plant pathology class he’d taken in college—he was tasked with identifying the virus.

  • 4.

    He checked out books on plant pathology and spent nine months studying the virus; during that time, he got hooked.

  • 5.

    He decided curing this virus would become his life’s work; he went back to school to earn his Ph.D. in plant pathology.

  • 6.

    As he further researched the virus, it started rapidly spreading and threatening the livelihood of Hawaii’s papaya farmers.

  • 7.

    Eventually, he genetically engineered the "Rainbow" papaya to be resistant to this devastating papaya ringspot virus.

  • 8.

    Rainbow papayas now make up over 75 percent of Hawaii's papayas; he’s largely credited with saving the industry in the state.

  • My main problem was stuttering, but I overcame that with increased knowledge and confidence and the pressure to do well in my first post graduate job interview.
