Research Interests

Climate change impacts science, social justice, & climate resilience; social & technical health-system innovation (community-centered); participatory local/regional sustainable development & capacity building; environmental & social justice; risk & vulnerability assessment; watershed stewardship, esp. aquifers; Latin American Region & rapidly industrializing countries.


Tim Downs is a specialist in environmental science and engineering with over 28 years field experience designing and managing collaborative projects in the UK, the United States, Latin America and Africa. His research focus is on how humans change the environment, and how those changes impact their health, wellbeing, and the ecosystems they inhabit. He is especially interested in issues of environmental and climate justice: the uneven distribution of positive and negative impacts across populations and landscapes. Downs works with diverse social actors to innovate through collaboration, both socially via new networks, and technically via new applications of science and technology.  He applies risk science and systems thinking to identify priority problems with stakeholders, GIS and analytics to understand inequities in existing social systems, vulnerabilities in technological systems, then innovation theory and collaborative capacity building practice to design, implement and monitor more sustainable solutions. In a diversity of settings—New England, Mexico, East and West Africa—he works with affected communities, NGOs, governmental agencies, public sector providers, the media, the private sector and donors, applying multi-stakeholder, interdisciplinary approaches within and across multiple sectors: health, energy, water supply & sanitation, food & agriculture, land-use, transportation, urban planning, climate-change adaptation & mitigation, biodiversity conservation & ecosystem stewardship.

Teaching Approach

Downs’s teaching and research are creatively combined. Half of his portfolio is foundational environmental science classes, and half team-based practicums.  As examples of practicums, in his Spring 2021 “Sustainable Development Assessment & Planning” class (IDCE332/EN242) student teams critically evaluated the assessment and planning process for 7 cases including a copper mining project, dams and reservoirs (3), a women’s empowerment project, a coastal climate resilience effort and a regional greenway project. In Spring 2021, team practicums in his “Cities, Regions, Climate Change & Health” class (IDCE365) included Hong Kong, Jakarta, Uttarakhand (Hindu Kush Himalaya), and New Orleans. Student teams constructively critique key operational stages (ethos & concept; integrated assessment; planning; implementation & management, monitoring & evaluation; capacity building), producing work of publishable quality (e.g. Downs et al. 2020b, 2020c below). This enhances their team research skills and their ability to design and deploy transformational integrated collaborative projects as professionals.

Awards/Grants/Research Projects

Since 2019, Downs has led the integrative collaborative project “Climate Change Impacts, Justice & Resilience in the Mexico City-Toluca Social-Hydroecological Region”, involving fellow IDCE faculty Morgan Ruelle and Yelena Ogneva-Himmelberger, and faculty from the National Autonomous University of Mexico (UNAM), National Polytechnic Institute of Mexico (IPN), Worcester Polytechnic Institute (WPI), UMass Amherst, and George Washington University. The Clark Team currently includes 3 undergraduate and 6 graduate students.

In summer 2018, Prof. Downs rode his motorcycle 6000 miles to join the Grannies Respond Caravan in protest of draconian family separation policy at the U.S.-Mexico Border.  He then raised money to send 7 IDCE students to volunteer helping heroic immigrant and asylum-seeker relief efforts in McAllen, TX. He and Profs. Anita Fábos and Sarah Mitchell, together with veteran social justice activist and student mentor Megan Martínez, co-authored a paper chronicling this impactful field research-meets-activism student experience (Glier et al., 2020a).

Since 2015, Downs has been collaborating with colleagues at Boston University and local residents to explore the vulnerability of the shallow aquifer system in Holliston, Mass. to contamination by natural Manganese and industrial chemicals. They are also looking into potential health risks to young children that may be the result of early life-stage exposures, including in-utero.

Exemplifying engaged collaborative research in partnership with affected communities, and co-authored with 9 IDCE students, the paper: "Integrated Assessment of Shallow-Aquifer Vulnerability to Multiple Contaminants and Drinking-Water Exposure Pathways in Holliston, Massachusetts" was published 2018 in open-access journal Water and is available online at: http://www.mdpi.com/2073-4441/10/1/23/html

Downs was a Co-Investigator with UMass Medical School on the Phase 1 (2008-2012) National Children's Study (NCS) project for Worcester County, funded by the National Institutes of Health.
