JAY M. HAM
Professor of agronomy

 

Photo of Jay Ham Environmental physics combines physics, ecology, soil science and meteorology in an effort to understand and explain the transformation processes that govern the fate of energy and matter within soils, plants and the atmosphere. Jay M. Ham, a Kansas State University professor of agronomy, is an expert in environmental physics and developed the environmental physics research program at K-State.

Ham's program has developed several new sensor technologies and measurement techniques. Examples include heat balance sap flow gauges for small stems, dual-probe heat capacity sensors for measuring soil moisture, conditional sampling techniques for measuring mass flux in the boundary layer and large chamber techniques for measuring carbon and water changes under carbon dioxide fumigation.

In addition to environmental physics, Ham researches field-scale carbon budgets, global climate change, instrumentation development, effects of elevated atmospheric carbon dioxide on energy and mass transport, turbulent transport from sparse vegetation and soil-plant-water relations.

Ham has published more than 40 journal articles and has received more than $3.7 million in grants since arriving at K-State in 1990.

Ham received his bachelor's degree in 1984 from K-State and his master's degree in 1986 from Oklahoma State University, both in agronomy. In 1990, he earned a Ph.D. from Texas A&M University in soil science.
