Research InterestsThe research in Howland’s laboratory focuses on vision, especially physiological optics. He has worked for many years on the development of refractive state in infants, children and young adults. Other projects have involved emmetropization and eye growth in chickens, measurements of monochromatic high-order aberrations of eyes, compensation for corneal aberrations by the internal optics of the eye, and measurements of accommodation in a variety of animals. Currently he works with undergraduate students to study image processing in humans. He is particularly interested in determining the saliency of different cues in distinguishing separate objects in the visual scene.
Professor Howland received his B.A. (1952) in Liberal Arts at the University of Chicago, his M.S.(1958) in Zoology at Tufts University, and his Ph.D. (1968) in Biological Sciences at Cornell University. Howland served in the U.S. Army in the U.S., Korea, and Japan from 1953-55. He was an Instructor at the State University of New York, Long Island Center from 1960-66 and Assistant Professor at the State University of New York at Stony Brook from 1966-67. From 1962-63 and 1964-66 He was a Scientific Assistant at the Max Planck Institut für Verhaltensphysiolgie, Seewiesen, Germany, in Abteilung Mittelstaedt. He was appointed as Assistant Professor at Cornell University in 1968, promoted to Associate Professor in 1974, and to Professor in 1985. Howland has spent academic leaves at Dunedin School of Medicine (New Zealand), Vision, Touch and Hearing Centre (Australia), University of Sussex (U.K.), the Institute of Ophthalmology, University of London (U.K.), Physiology Department, Cambridge (U.K.), The School of Optometry at the University of Manchester,(UK) the School of Optometry and Vision Science in Brisbane (Australia), and the Max-Planck Institut für Verhaltensphysiologie (Germany). Howland is a fellow of the Optical Society of America, a member of several professional societies, and has served on the editorial boards of Vision Research, and currently serves on the editorial board of Ophthalmic and Physiological Optics.
