Research Interests

Primary focus on environmental engineering, in particular, physical/chemical and biological treatment processes for industrial, agricultural, and municipal liquid and solid wastes.

Recent research has emphasized on high-rate anaerobic waste treatment process development and valuable byproduct (ie. energy byproducts: methane, hydrogen; nutrients: P, K, N) recovery from waste streams.
Biological Hydrogen fermentation from wastewater,
Temperature-Phased Anaerobic Digestion (TPAD) of biosolids, municipal refuse and livestock wastes
Demonstration of Anaerobic Sequencing Batch Reactor (ASBR) process for swine waste and
industrial wastewater,
Biological sulfide conversion to elemental sulfur,
Bioleaching for heavy metal removal study, and
Sodium and ammonia inhibition study in thermophilic anaerobic digestion.
Anaerobic membrane process

Biological Nutrient (nitrogen and phosphorus) Removal (BNR)
Upgrade, retrofit and design BNR plants
Regulatory compliance through reliable and consistent biological removal of nitrogen and phosphorus, without chemical addition
Flexible design to accommodate variations in organic and nutrient loading
Beneficial use of nutrient-rich sludge
Process optimization of existing facilities
Modeling the BNR plants
