Courses:
NRM 106 - Introduction to Natural Resources Management
NRM 211 - Introduction to Applied Plant Science 
Research Interests: The research is concentrated on
environmental plant physiology as it applies to commercial
horticulture at high latitudes. Special attention
is placed on understanding relationships of temperature,
light and environmental conditions for whole plant
development, growth, morphology and flowering. Guidelines
and protocols are developed for the implementation
of the physiological findings to optimize, improve
and support efficient crop production in greenhouse,
modified or controlled environments.
Current Research Programs:
1) Berry research, AK. USDA-CSREES, 2003-2005,
2) Innovative use of natural and supplemental light
for high latitude crop production. USDA-Hatch. 2000-2005
3) The Good agricultural practices (GAP) program.
USDA-CSREES and the USFDA. 2002-2005
