Completed Research Projects

Environmental Conservation

The goal of this project is to clarify the essential link between the best design and management practices for green infrastructure in new suburban residential developments, the actual results those practices achieve, and the value that residents place on the protected areas.

With increased pressure to utilize more practical, ecological and economically feasible strategies to manage turfgrasses, research is needed to identify best management practices to preserve water resources. The primary goal is to increase sustainability of turfgrass by addressing water conservation issues, including (i) efficient irrigation strategies based on actual turfgrass water use, (ii) drought resistant species and cultivars, and (iii) an artificial wetland system to aid in preservation of water quality from managed turf settings.

The goal of this research is to gain better insight into the decision making process of Massachusetts forest-owning families in regards to the future of their land so that educators may tailor outreach programs and material to help these families make informed decisions about it. The cumulative effect of the independent decisions that these landowners make about their land will determine the future of our landscapes and the public benefits they continue to provide (or not to provide).

Reaching the potential for renewable biofuels depends on the development of new technologies that are able to release the energy stored in cellulose fibers. This research project centers around an unusual microbe, Clostridium phytofermentans, that can convert a broad range of biomass sources directly to ethanol without expensive thermochemical pretreatment. Further development of conversion processes using C. phytofermentans will create a path to renewable biofuels using our region's sustainable forestry and crop resources.

Energy

A home that has been designed according to LEED green building standards may not necessarily be sustainable unless the systems operations and maintenance are tuned up and owners are. This project will include environmental audits of fourteen LEED-certified homes in New England at least twelve months after they were occupied. Findings will be evaluated by comparing baseline (predicted) performance data (LEED documentation) with actual operational data in order to identify the issues that effect sustainability.

Food banks are major consumers of energy related to food handling and storage as well as major customers for local food producers. Energy efficiency and cost reduction in food banks could have synergistic benefits for both types of enterprise. This project will develop a process map to integrate energy and food handling audits tio help identify key nodes for effective energy efficiency and food safety interventions. By evaluating  technological innovation in the context of the local post-harvest food system the food banks can optimize energy efficiency and food safety.

This multidisciplinary project will promote the use of biochar and bio-oil generated from agricultural/forest organic wastes to enhance small farm sustainability through providing renewable fuel, and improving soil quality and crop productivity, and to improve the environment through sequestrating greenhouse gases and reducing the mobility and exposure of contaminants in soils.

This project will examine the effect of natural diversity on biofuel production efficiency by using a grass energy model organism (Brachypodium distachyon), and treatment with both biological and thermochemical conversion.

Water

This project utilizes robotic submersible technology to characterize submerged aquatic vegetation (SAV) blooms in the Charles River in Massachusetts.

This project involves monitoring the levels and locations of EDCs (endocrine disrupting compounds) in the Assabet River of eastern Massachusetts to advance the protection of the aquatic environment.

Researchers will evaluate the potential use of field indicators of hydric soils to characterize wetland hydroperiods with respect to frequency, depth, and duration of water table fluctuations; test the effectiveness of proposed hydric soil indicators to identify 'problem hydric soils'; test monitoring protocols used to identify reducing conditions to determine if they are effective within a range of soil conditions within the Northeast; and investigate the hydraulic properties of hydromorphic soils with episaturation.

This project has three components to increase sustainability in Massachusetts cranberry production:

  • development and demonstration of sustainable practices for the management of the most severe pest problems: cranberry fruitworm, fruit rot disease, and the parasitic weed dodder.
  • investigation of practices to conserve water and fuel.
  • work with growers to implement nutrient management Best Management Practices (BMPs).

This project will study and numerically model road salt impact on water quality in a typical aquifer in eastern Massachusetts.

This study will examine threats to water security and potential impacts on water quantity and quality in watershed systems. The main goal of the study is to evaluate the effects of land use, extreme precipitation, and climatic stressors on water security (quantity and quality) and potential mitigation opportunities at a river basin scale. Geographic Information Systems (GIS), uncertainty analysis, simulation modeling, and a multi-attribute decision framework will be used to evaluate and advance water security in watershed systems.

Food Science

This research focuses on utilizing emulsion technologies to allow omega-3 fatty acid incorporation into foods and to increase the bioavailability of these important dietary fats.

Dietary factors are important predictors of long term health and the incidence of chronic disease. Laboratory methods will be employed, primarily in vitro models, such as in vitro digestion and tissue cultures, which will be used to evaluate the bioactivity of nutrients and other food bioactives to understand the mechanisms. The investigator will seek to advance the science of defining the role of bioactive dietary constituents for optimal human health. This will provide fertile grounds for ongoing collaborations and future collaborative research and grant proposal development.
