The Diapause Research Foundation was established in 2004 as a nonprofit 501(c)3 corporation through annual contributions from Triops, Inc. and Dr. Eugene Hull, who specializes in the study of vertebrate diapause.

DRF seeks to advance research on diapause control through its own labs and by supporting the work of other qualified scientists. As part of its activities, the foundation will maintain annual killifish populations manipulated to produce embryos that either enter or bypass diapause in a fixed time. Embryos in a state of diapause and embryos that bypass diapause will be used to develop a biological assay that will further chemical studies and help determine the biochemical/chemical control of diapause. Through shared research, DRF will contribute practical applications of diapause to advance human medicine, anti-aging, environmental toxicant testing, pest control and perhaps one day, even space travel.

DRF provides educational materials on diapause and its applications. These will include age-appropriate online curriculum guides that give an introduction to the developmental biology of the annual killifish. DRF also collaborates on projects by college students, professors and museum staff by offering technical advice and hatching materials when available.  


Director, President, Secretary
Eugene Hull, B.A., M.S., PhD., has 10 years’ experience researching embryonic diapause in shrimp and fish. The company he directed received a U.S. patent for a peptide for the treatment of AIDS and published this work in medical journals. He has also worked with the U.S. military and jointly received a patent in the use of diapausing embryos to test for toxicants in the aquatic environment. Dr. Hull has addressed the World Health Organization on the biological control of mosquitoes using embryos in diapause and has developed several award-winning educational diapause products used by more than 16 million children worldwide.
