    The Canadian-American biologist Edmund Vincent Cowdry played an important role in the birth and development of the science of aging, gerontology. In particular, he contributed to the growth of gerontology as a multidisciplinary scientific field in the United States during the 1930s and 1940s. With the support of the Josiah Macy, Jr. Foundation, he organized the first scientific conference on aging at Woods Hole, Massachusetts, where scientists from various fields gathered to discuss aging as a s…Read more

    Senescence, Growth, and Gerontology in the United States
    Journal of the History of Biology 46 (4): 631-667. 2013.
    This paper discusses how growth and aging became interrelated phenomena with the creation of gerontology in the United States. I first show that the relation of growth to senescence, which had hardly attracted scientific attention before the twentieth century, started to be investigated by several experimental scientists around the 1900s. Subsequently, research on the connection between the two phenomena entered a new domain through the birth of gerontology as a scientific field comprised of var…Read more

    SUMMARYBy examining the use of tissue culture in post-war American biomedicine, this paper investigates how scientists experience and manage failure. I study how Leonard Hayflick forged his new definition of failure and ways of managing it by refuting Alexis Carrel's definition of failure alongside his theory of the immortality of cultured cells. Unlike Carrel, Hayflick claimed that every vertebrate somatic cell should eventually die, unless it transformed into a tumour cell. This claim defined …Read more

    Science, state, and spirituality: Stories of four creationists in South Korea
    with Kyuhoon Cho
    History of Science 56 (1): 35-71. 2018.
    This paper presents an analysis of the birth and growth of scientific creationism in South Korea by focusing on the lives of four major contributors. After creationism arrived in Korea in 1980 through the global campaign of leading American creationists, including Henry Morris and Duane Gish, it steadily grew in the country, reflecting its historical and social conditions, and especially its developmental state with its structured mode of managing science and appropriating religion. We argue tha…Read more

    Bimorph deformable mirror: An appropriate wavefront corrector for retinal imaging?
    with S. Laut, S. Jones, S. da HorsleyOlivier, and J. S. Werner
    The purpose of this study was to evaluate the performance of a bimorph deformable mirror from AOptix, inserted into an adaptive optics system designed for in-vivo retinal imaging at high resolution. We wanted to determine its suitability as a wavefront corrector for vision science and ophthalmological instrumentation. We presented results obtained in a closed-loop system, and compared them with previous open-loop performance measurements. Our goal was to obtain precise wavefront reconstruction w…Read more
