Lifecycle Design and Manufacturing

Life Cycle Thinking is about going beyond the traditional focus on production site and manufacturing processes to include environmental, social and economic impacts of a product over its entire life cycle (UNEP SETAC Life Cycle Initiative)

The Lifecycle Design and Manufacturing (LDM) research group creates computer-aided tools and technologies for supporting data-driven, product lifecycle management. We have a strong focus on integrating environmental sustainability assessment and decision-making into product and process design. Our research lies at the interface of engineering design, manufacturing engineering, information modeling, human-computer interaction, and environmental engineering.


  • Integrating environmental sustainability into product conceptualization
  • Manufacturing process modeling for estimating resource efficiencies
  • Multi-criteria optimization & decision analysis for balancing sustainability, performance, and cost
  • Data-driven modeling and digital exploration tools for product lifecycle data
  • Assessing environmental performance of product supply chains


Our research is focused on the following themes,

Environmental sustainability-based decision-making in lifecycle engineering

  • creating streamlined indicators and ideation-support tools in conceptual and early product design 
  • developing visualization & analytics tools for product lifecycle information
  • data-driven process modeling for sustainable manufacturing

Design, systems optimization, and assessment of technologies for sustainable development

  • environmental sustainability assessment of photovoltaic powered electrodialysis desalination
  • multi-criteria decision-making and technology assessment for supporting sustainable development goals 

Socio-technical approaches for human-centered sustainable design

  • assessing end-user preferences and perceptions of sustainability
  • incorporating user behavior into design of energy using products

Teaching sustainable design & manufacturing in engineering curricula

  • creating rapid design exploration and prototyping tools for experiential learning
  • integrating sustainable product design into undergraduate education through guided discovery instruction

Sustainable Design & Production



We are always interested in working with motivated MSc. & BSc. students. Please schedule an appointment with Dr. Ramanujan if you are curious about potential project ideas.
