CV

Dr. Lansing leads the Bioenergy and Bioprocessing Technology Lab at the nexus of renewable energy, water quality, waste treatment, and human health, and is committed to understanding the ecological, engineering, and social systems that influence these intertwined areas.

Research Areas

Anaerobic Digestion

Anaerobic digestion is a series of sequential microbial processes to transform organic material into biogas, which can be used as a renewable energy source to produce electricity, fuel, or heat. Anaerobic digestion reduces CO2 emissions, while providing renewable energy and a high- quality fertilizer. We incorporated innovations into the digestion process, propelling this field.

Topics include:

  • Bioenergy and waste treatment using ecological engineering
  • Waste to Energy Research: Anaerobic digestion, microbial fuel cells, gasification, and solid-oxide fuel cells
  • Small-scale digesters for the US and developing countries
  • High temperature and high pressure anaerobic digestion
  • Effects of nanoparticles on anaerobic digestion and post-digestion utilization
  • Energy (eMergy) and life cycle assessments (LCA)

Food Energy Water Nexus

Food, water, and energy systems are intimately connected. Water and nutrients are needed to grow crops and feed animals. Agricultural runoff can degrade water quality and increase eutrophication, while energy is integral to both agricultural production and water treatment. The connection between these systems is known as the Food-Energy-Water (FEW) Nexus.

Topics include:

  • Recovering nutrients from waste using post-nutrient extraction after anaerobic digestion
  • Nutrient recovery from Chesapeake Bay using algal turf scrubber (ATS) with anaerobic digestion of algae feedstocks to drive a fuel cell at the Port of Baltimore
  • Food waste, dairy and poultry manure digestion in Maryland, as well as sanitary waste digestion in Haiti

Antimicrobial Resistance

Antimicrobial resistance is of increasing concern, with antibiotics use in agriculture and public health settings leading to an increase in bacterial resistance in the environment.

Topics Include:

  • Antimicrobial resistance, persistence and treatment in dairy and beef manure waste management processing and the wastewater industry
