Professional Experience

1967 70 Graduate School, Univ. of Calif, Riverside National Science Foundation Predoctoral Fellowship 3 year Fellowship. Publication numbers 1,2 and 3 resulted from my Ph.D.. research. 1970 71 Univ. of Calif., Riverside NIH Postdoctoral Fellow This fellowship research focused upon understanding if the effects of various air pollutants on needles of coniferons tree species can be detected on the cellular level before any visible needle injury occurs. Do various air pollutants produce specific signatures on the cellular level. Publication numbers 4,5,11 and 16 resulted from this research. 1971 72 Biology Dept., Univ. of Calif., Riverside EPA Postdoctoral Fellow This research centered on the molecular and physiological basis of ozone insult to leaf cells. The findings demonstrated that the primary or first site of injury is the plasma membrane. Publication numbers 6,7,9,10 and 14 resulted from this research. 1972 75 Brookhaven National Laboratory, Biology Dept. Postdoctoral Fellow Two National Cancer Inst. (NIH, DEHW) postdoctoral Grant Fellowships (1 FOZ CA52766 Cl and PHS CA 08888). Research was aimed at understanding the chemical controls of the cell cycle. Specifically results demonstrated that (1) cells of plant roots are preconditioned to stop in particular G1:G2 percentages when cells are still meristematic, (2) the primary insult of chronic and acute gamma irradiation to cells is DNA and that the duration of vulnerability is proportional to the duration of the cell cycle, (3) there is an unidentified substance in cotyledons of peas that promotes cell arrest in G2 in roots and shoots of garden peas and other legumes. Publications include references 8,12,13,15,17 and 18. 1975 82 Assistant Professor, Laboratory of Plant Morphogenesis, Manhattan College, The Bronx, NY 10471. 1975 1985 Contracts #368407, #469167, and #550925 S from Brookhaven National Laboratories, Assoc. Universities, Inc. under the auspices of the U.S. Dept. of Energy. 1975 1985 Consultant and Co PI Department of Energy and Environment, Brookhaven National Laboratory Principal Investigator of research group to study the "Effects of Acid Rain on Vegetation" under the contracts EY 76 C 02 0016 and DE AC02 76CH00016 with the United States Dept. of Energy and the United States Environmental Protection Agency. Research involved the botanical effects of acidic precipitation acid rain on terrestrial plants. Research involved technologies to distribute simulated rainfalls in controlled experimental and field conditions, designed a large number of field experiments to test rainfall acidity effects. Explored effects on a large number plant species. These investigations at Brookhaven and Manhattan College produced more peer reviewed publications than all other research groups in this research area taken together in the United States. Publication numbers in this area are: 19,20,21,34,25,26,31,32,33,34,36,37,38,39,40,41,42,43,45,46, 47,49,51,52,53,54,57,48,59,60,61,62,63,64,66,68,71,72,73,74,75, 77,78,79,81,82,83,84,85,87,88,89,90,93,95, and 96. 1976 78 Grant # 1 R01 GM 23232 from the National Institutes of General Medical Sciences, National Institutes of Health, U. S. Dept. of Health, Education and Welfare. Research was directed at the chemical controls of the cell cycle in plant root meristems. Specifically, experiments were directed understanding the chemical and physiology nature of a naturally produced substance that promoted cell arrest in G2 in pea root meristems. This substance was chemically identified as trigonelline. Additional research was aimed at understanding how this natural substance was controlled the cell cycle in root cells as well as the cell cycle kinetics of endopolyploid development in root cells of peas exposed to protracted gamma irradiation. Publication numbers 27,28,29,30, and 44, and 48 were developed from this grant. 1977 Undergraduate Research Participation Grant (SMI 76 83850) from the National Science Foundation. This grant provided research support for several student research projects including Ms. Donna Bozzone and Mrs. Theresa Curry. This grant contributed to research for publication numbers 26,31,32,33, and 35. 1977 Placed on the TE 2 (Agricultural Plant Effects) Committee of the Air Pollution Control Association. I am on this committee but rarely attend meetings. As a result of activity on this committee I was placed in charge of writing an extensive review of the acidic precipitation field. This effort resulted in publication number 41, a very difficult task. 1978 81 Elected to the Steering Committee of the Air Pollution Workshop. I was elected as one of two people to this committee in 1978. I learned the procedures for organizing the technical sessions over the next two years. During the third year the two people elected trained for two years were expected to organize the Workshop in 1981. The other person elected in 1978, from Colorado State University, was not active in Air Pollution Research by 1981. As a result, I organized and directed all aspects of the fifteen technical sessions at the Workshop held at Cornell University in April 1981. 1979 Organized and directed the "International Workshop on the Effects of Acid Precipitation on Vegetation/Terrestrial Ecosystems" held at Brookhaven National Laboratory, June 11 14. Supported by the United States Environmental Protection Agency. Interagency Agreement EPA 79 07068L. For this international Workshop, I selected the participants, assisted in all aspects of housing arrangements, session topics, and edited the proceedings from audio tape and written materials. The proceedings were published as a Brookhaven National Laboratory Report. 1981 84 Research Contract with BASF Atkiengesellschaft, Limburgerhof, FRG, The contract with this international firm headquartered in West Germany, was focused upon understanding if trigonelline could have viable economic potential as a plant growth regulation. Research centered upon testing to determine if trigonelline could increase legume crop yields through its effects on root growth. Initial experimental results were promising. These initial results formed the basis for a patent application owned by Manhattan College. 1982 Gave testimony to U.S. Senate Committee on Environment and Public Works on Effects of Acid Precipitation on Crops. I gave senate committee testimony as a member of a scientific panel on two separate occasions. 1982 1989 Associate Professor of Biology, Laboratory of Plant Morphogenesis, Manhattan College. 1982 Grant in Aid with Occidental Research Corp., Irving, CA. This small research grant in aid to Manhattan College was a "payment" for my services as a consultant on matters related to Acid Rain. I believe the grant in aid only lasted one year because my "political" philosophy about research in the acid rain field was not well aligned with theirs. Publication number 75 resulted from this grant. 1983 84 Grant 1 ROl GM30290 from the National Institutes of Health, Department of Health and Human Services. This research grant centered on understanding (1) relationships between trigonelline concentrations in plant tissues in relation to trigonelline's role as a cell cycle regulation, (2) the metabolism of the pathway for which trigonelline is a branch point, (3) the structural requirements of the trigonelline molecule necessary for cell cycle regulation, and (4) the chemical structure of a natural product which has an antagonistic 1982 Gave testimony to U.S. Senate Committee on Environment and Public Works on Effects of Acid Precipitation on Crops. 1982 Grant-in-Aid with Occidental Research Corp., Irving, CA. 1983-84 Grant 1-RO1-GM30290 from the National Institutes of Health, Department of Health and Human Services. 1984-86 Grant from Asgrow Seed Company (Upjohn Co.) for research. 1985-2002 President, Board of Trustees of the United Methodist Church of the Tarrytowns. 1986-1993 President, Glenville Fire Co., Tarrytown, NY. 1989- Professor of Biology, Laboratory of Plant Morphogenesis Manhattan College 1986-1991 Several contracts with Brookhaven National Laboratory to design and operate an open air, gas fumigation facility. Publication number 99 resulted from these contracts. 1987-1990 Several contracts with the National Council for Air and Stream Improvement for the Pulp and Paper Industry. Contracts were for research to understand the degree that ozone influences needles of loblolly pine. Several contracts with the National Park Service. Research centered upon understanding the effects of air pollutants and other environmental influences on vegetation in National Parks. Manhattan College hosted the 44th Annual Eastern Colleges Science Conference. I was the coordinator. Obtained a PEW Trust grant to start a long-term monitoring effort at Tucson Mountain Park, Tucson, AZ. --Nine students worked with me in Tucson, AZ on the health of 1500 saguaro cacti. These cacti were re- evaluated in the summer of 2002. 1980 and 90’s I was a member of Manhattan College’s Council of Faculty Affairs for 12 years. I was chairperson of the Council for three years during that time period. 1995-2009 Elected, Chairperson of the Board of Directors, Eastern Colleges Science Conference, Inc. 1996 Sabbatical Leave to study cacti in Arizona and Mexico. 1996-2003 Maintained a co-operative experiment with Dr. Joseph Sullivan at the University of Maryland in which he would expose cactus plants to UV-B and UV-A irradiation. Maintained a research relationship with Dr. Zella Kahn-Jetter on the mechanical aspects of plants. . 2002 Re-evaluated 1,200 saguaro cacti during the summer of 2003 with three students. This was a follow-up of research during the summer of 1993. Awarded the Catherine and Robert Fenton Endowed Chair of Biology Started research on the mechanical properties of tree branches.
