Ressler is a soil scientist and teaches Environmental Science, Wetlands Analysis, Soil Science, Geographic Information Systems, Chemistry of Natural Water, and Groundwater Pollution and Monitoring. He has published articles in scientific journals about nutrient dispersal and uptake by crops after application by traditional and improved fertilizer injectors. He holds two patents on fertilizer injectors.
His work at the Centralia, Pa., mine fire has led to an article about high temperature nitrogen cycling, as well as work on soil gas and trace metal redistribution and plant uptake. He is currently working on trace metals in plants and soils when biosolids are applied to New Zealand pasture soils to beneficially use this wastewater treatment byproduct.
Ressler has directed student research projects examining the ecological effects of uncontrolled mine fires on soils and plants, wetland hydrology and geochemistry, lake sedimentation projects, and urban tree inventories in Sunbury and Selinsgrove.
