A notable accomplishment was that he was instrumental in securing the funding for the Natural Sciences Facility which was the first new classroom building built on the UAF campus since 1971. The building opened in 1997 and in 2007 was it was renamed the Reichardt Building, in the former dean’s honor. Also in 2007, Reichardt was honored by the University of Alaska Foundation with the Edith R. Bullock Prize for excellence.

Kolf O. Jayaweera

  • 1985-1990 Dean

Kolf O. Jayaweera was the first Dean of the College of Natural Science, occupying that role from 1985-1990. He served UAF from 1970-1991. Jayaweera was instrumental in creating the structure that would sustain the college to the present time. Prior to this, the departments that now comprise the college were scattered throughout the campus. He was a professor of physics (emeritus as of 1992) who served previously as an associate professor of geophysics.

Jayaweera retired from Cal State Fullerton in 2005 after serving for 15 years as dean of the college, as well as a dual appointment in 1997 as acting dean of the College of Engineering and Computer Science.

During his tenure as NSM dean, he encouraged faculty members to pursue funding for a comprehensive evaluation of teaching and learning in the college. The effort, known as the Undergraduate Reform Initiative, was funded by the National Science Foundation and led to curricular changes to improve the quality of the educational experience, including the development of new courses. Jayaweera is credited with initiating and implementing a variety of programs to bolster student success. He provided space and funding for the college’s Opportunity Center for Science and Mathematics Students, which led to the launch of the college’s Dimensions student research journal; its 14th edition was published this spring on CD.

Jayaweera earned his Ph.D. in physics at the University of London and B.S. in physics at the University of Ceylon. He went on to became a U.S. citizen and was selected by the National Academy of Sciences to serve as a U.S. delegate to the First Special Assembly of the International Association of Meteorology and Atmospheric Physics in Melbourne in 1974.

His research activities included work in the areas of air pollution, cloud physics, atmospheric radiation and global climate changes.

Brina Kessel

  • 1962-1972 Dean

Brina Kessel joined the faculty of the University of Alaska Fairbanks (UAF) as an instructor in zoology in the summer of 1951. She advanced quickly to professorship, serving as head of the Department of Biological Sciences from 1957 through 1966 and as dean of the College of Biological Sciences and Renewable Resources from 1961 to 1972. For the University of Alaska Museum, she was curator of terrestrial vertebrates from 1972 to 1990 and curator of ornithology from 1990 until her retirement in 1997.

Kessel was graduated from Cornell University in 1947 with a Bachelor of Science degree. She then went to the University of Wisconsin to study with Aldo Leopold. Unfortunately, Leopold died fighting a fire on his property in 1948. She also learned that the university did not accept women into its doctoral program in wildlife management. She received a master's degree from Wisconsin in 1949 and returned to Cornell to resume her studies with Arthur Augustus Allen. Kessel collected some of the first recordings of bird vocalization at Cornell. With her dissertation on the European starling, she received her PhD in 1951.[1]

Brina Kessel conducted research on many aspects of Alaska's bird life over a span of more than 55 years. A particular interest was birds of the taiga and tundra. Her early research in the 1950s explored the lands of Naval Petroleum Reserve Number 4 on Alaska's North Slope; however, in those days the Department of Defense did not permit women to conduct fieldwork on the property. Thus, Tom Cade and George Schaller worked in the field, while Kessel wrote up results as principal investigator. A few years later, Kessel worked in the Brooks Range with Margaret Murie and her husband Olaus Murie. Kessel worked in the field for many years studying the avifauna of the Seward Peninsula.[1]

Kessel's research culminated in publications that include Birds of the Seward Peninsula, Alaska (1989) and Habitat Characteristics of Some Passerine Birds in Western North American Taiga (1998).[1]

Kessel brought her scientific expertise to several projects in the realm of Alaskan economic development. In the early 1980s, she performed fieldwork in the upper valley of the Susitna River in anticipation of a hydroelectric dam project.[2]

Brina Kessel was named a fellow of the American Association for the Advancement of Science in 1960. In 1973, she became one of the first women to be named a fellow of the American Ornithologists' Union (AOU); she served the AOU as president from 1992 to 1994.[2] The AOU, now the American Ornithological Society, established the Brina C. Kessel Award to recognize an outstanding recent article published in The Auk: Ornithological Advances.[11] Kessel was elected to fellowship in the Arctic Institute of North America in 1978.[12] From the University of Alaska, she received its President's Distinguished Service Award in 1981.[2]

Brina Kessel, through her estate, made a large gift to the University of Alaska to fund the Birds of Alaska project and to establish the Kessel Ornithology Endowment Fund.[10]The Brina Kessel Medal for Excellence in Science is granted annually to an undergraduate student at UAF.[2][10] Kessel Pond at Creamer's Field Migratory Waterfowl Refuge in Fairbanks was named in her honor.[2]
