Research Interests
The 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 involve emmetropization and eye growth in chickens, measurements of monochromatic high-order aberrations of eyes, and compensation for corneal aberrations by the internal optics of the eye, and measurements of accommodation in a variety of animals.
Biographical Sketch
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 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 fuer 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.), and the Max-Planck Institut fuer Verhaltensphysiologie (Germany). Howland is a fellow of the Optical Society of America, a member of numerous professional societies, and has served on the editorial boards of Vision Research, and currently serves on the editorial board of Ophthalmic and Physiological Optics.
