Welcome to the Sustainability Engineering Lab at The University of Toledo
Our current research program involves four areas:
Water infrastructure sustainability
(Green infrastructure, water-energy nexus, solids management, composting toilets, rainwater harvesting, constructed wetlands)
(Thin film solar cells)
Food sustainability (Ecosystem services versus life cycle impacts of urban agriculture)
(Project based learning, sustainability education, information literacy)
In our research we use modeling and analysis tools including life cycle assessment, carbon footprint analysis, geochemical modeling, fate and transport modeling, multi-criteria decision analysis, web based software design, uncertainty analysis, agent based modeling, and ecological design principles.
(Recycled materials, pollution from roads, road hydrology)

As of Summer of 2015, most of our lab news will be posted on our Tweet. We invite you to follow us on Twitter if you are interested in our activities.
Our lab receives funds to collaborate with Autonomous University of Barcelona (UAB) and Polytechnic University of Catalonia (UPC) in Spain. Jay and Robert have been Skyping biweekly with Anna and Violeta to focus the topic of our collaboration and to plan their one month visit in Barcelon this summer.
UT-UPC-UAB collaboration: biweekly skype calls.
Our paper on Energy Payback Times of PV systems is
in Renewable and Sustainable Energy Reviews journal. Congrats to Jenny for her hard work on this paper!
Jay Devkota publishes his manuscript,
//Life Cycle Based Evaluation of Harvested Rainwater Use in Toilets and for Irrigation//
, in the Journal of Cleaner Production! Nice work, Jay!
2015 welcoming lunch for new students joining the Sustainability Engineering Lab. Ilke Celik and Ashish Sharma join as PhD candidates, Henry Rodrigues joins as a MS student, and Bangyu Wang joins us as an undergraduate researcher.
Robert Phillips receives the University of Toledo College of Engineering Outstanding Teaching Assistant award. Congratulations Robert!
Drs. Isaam Al-Khatib and Muath Abu Saad from the Birzeit University, Palestine visited
Dr. Defne Apul
’s research team, the Sustainability Engineering Research Lab, for three days to discuss potential collaborative efforts for research related to rainwater harvesting and water scarcity. Their visit is part of the
that they received from NSF/USAID. The three-day visit consisted of presentations from the respective groups, outlining their research objectives and preliminary findings, tours of the University of Toledo’s on-campus best management practices and other sustainable initiatives, a visit to Toledo’s
Lake Erie Center
, and a tour of the local wastewater treatment plant.
Additionally, during their time at UT, Dr.s Isaam Al-Khatib and Muath Abu Saad met with the student chapter of Engineers Without Borders to discuss civil engineering problems in Palestine and the potential for projects and funding sources. The teams will be continuing their collaborative effort over the next several months to identify areas of synergy between the groups and prospective outcomes.

’s team, the Sustainability Engineering Lab, recently supported two graduate students work at the University of Manchester with
Dr. Adisa Azapagic
’s team, the Sustainable Industrial Systems lab, through an international collaboration grant funded by the National Science Foundation. Jay Devkota (PhD) and
(MS) spent two months this summer (June-July) working closely with the Manchester team to further their research on sustainability evaluations of rainwater harvesting systems across regions and investigating the life cycle impacts from diffuse urban stormwater pollution, respectively. The two teams are continuing to work together to further their areas of research in the field of sustainable systems.

Sustainability Engineering Lab began collaborating with the Sustainable Industrial Systems Lab of Dr. Adisa Azapagic of University of Manchester, U.K.. Jay Devkota and Robert Phillips will be visiting Dr. Azapagic's group in Summer 2014. The funding for this collaboration is provided by NSF.
December 7, 2012:
Dr. Apul's article on "
Navigating the Academic Job Search for Environmental Engineers: Guidance for Job Seekers and Mentors
" is published in Journal of Professional Issues in Engineering Education and Practice. This article may be appealing and helpful to PhD students, postdocs, and their mentors.

Sustainability Engineering Lab member
Robert Phillips wins the best poster award
at American Water Works Association (AWWA) Ohio Section's 74th Annual Conference in Dayton, OH. At the conference Robert presented his work on economic and environmental evaluation of rainwater harvesting systems using the EEAST model. Robert participated in the Undergraduate Summer Research and Creative Activity Program (USRCAP) of the University of Toledo as well as the Research to Practice Program of US Green Building Council (R2P2 USGBC). His AWWA Poster award comes with a $100 check. His award winning poster can be downloaded from
