Our research is motivated by the following dilemma facing humanity. On the one hand, engineering plays an essential role in meeting our needs and enhancing our well-being. Evidence of this includes products like transportation fuels, vaccines, medicines, plastics, artificial fertilizers, etc. However, on the other hand, engineering also contributes to degradation of the very ecosystems that are essential for our well-being. Examples include climate change due to greenhouse gas emissions from mobilization of fossil fuels, harmful algal blooms due to runoff of artificial fertilizers, and plastic pollution due to littering and lack of biodegradability.
To address this dilemma, we are developing systematic methods and tools to transform engineering so that its results are ecologically viable, socially desirable, and economically feasible for present and future generations. For this, we adopt a transdisciplinary approach for convergence of engineering with disciplines such as environmental economics and ecosystem ecology. To prevent unintended harm from engineering activities, we consider a large system boundary from individual molecules and reactions, to manufacturing processes, their life cycles, the economy, and the biosphere. This is depicted in the adjacent figure. Our research is computational in nature and relies on advanced techniques from mathematical modeling, optimization, statistics, and machine learning.
Current projects are developing innovative designs by seeking synergies between human and natural systems, including the role of ecosystems in sustainability assessment, enabling a circular economy of plastics, decarbonization of the chemical industry, and planning to meet campus carbon neutrality goals.

Research
All human activities are sustained due to the availability of goods and services from nature. For example, as shown in the figure, vegetation cleans air pollution while wetlands remove water pollutants. In addition they provide many benefits to society such as pure water, oxygen, biomass, and recreation. However, most disciplines, including engineering have ignored this critical role of nature. Designs based on such ignorance invariably exceed nature's carrying capacity, making them inherently unsustainable.
Our framework of techno-ecological synergy (TES) encourages harmony between human and natural systems: ecosystems provide goods and services, while human systems protect and restore nature. This framework provides new sustainability metrics, methods for life cycle assessment, novel designs of manufacturing processes, industrial landscapes, and process operation. These designs are often economically and environmentally superior to designs provided by traditional techno-centric methods.
Sustainable engineering is an inherently multiscale problem, which requires theoretical advances to bridge relevant scales and address the challenges such as uncertainty. We have developed the Process to Planet (P2P) multiscale modeling framework, shown in the figure, to integrate the benefits of models from engineering, life cycle assessment, and economics. It enables integration of nonlinear and fundamental models of engineering systems with linear and empirical models of the life cycle and economy. The resulting model can be used to design processes and supply chains while accounting for their life cycle environmental impact. It can also be used to determine the effect of macro-economic changes such as a carbon tax and new technologies on individual processes and their life cycle. We are also developing ways of incorporating ecosystem services in this multiscale framework to enable landscape design, and the molecular scale to design chemical reaction networks for making a specified product.
Our research is closely related with our education activities since meeting the goals of sustainability require both. Professor Bakshi has developed and taught an elective course on Sustainable Engineering for the last twenty years, which has resulted in a textbook on this subject. In addition to teaching this full-semester course at OSU, he has also taught shorter versions across the world at various corporations and at institutions such as Massachusetts Institute of Technology, South China University of Technology, McGill University, and Indian Institute of Technology in Mumbai and New Delhi. These courses introduce the principles of sustainable engineering to practitioners, university faculty, and corporate executives.
The only system we know that has been able to sustain itself for millennia is nature. One reason why nature is sustainable is because waste from one species is food for another. This is due to biotic (e.g. food web) and abiotic (e.g. carbon cycle) cycles in nature. The concept of a circular economy aims to mimic such cycles for technological products. Thus, in a circular economy, materials are retained in the economy for as long as possible so that the net input from nature is reduced, as is environmental impact.
The figure shows a typical circular system for plastic products. Along with being circular such a system also needs to reduce environmental impact over its life cycle and be economically feasible. We have developed a computational framework for analyzing and designing sustainable and circular systems. Our specific focus is on developing a circular economy of plastics and on decarbonization of the chemical industry.
How do we transition to a sustainable future? Systematic methods are needed to answer this question since an increasing number of corporations, nations, universities, and other organizations are aiming to meet sustainability goals such as being carbon neutral, water neutral, nature-positive, and zero waste. We are developing such systematic methods, with current emphasis on guiding university campuses toward carbon neutrality. This involves choosing between a large number of alternatives for reducing the direct and indirect emissions of greenhouse gases (carbon footprint) over a time horizon of a few decades. These alternatives include sources of electricity and heat, ways of improving building efficiency, ecologically friendly land use on campus, changing commuting routines and conference travel, purchasing offsets, etc. We have contributed to developing the 2020 climate action plan of The Ohio State University. We have also developed a general framework and software for developing such plans by solving a long-term planning problem. Typical results shown in the figure convey the sequence of actions that could lead to carbon neutrality by 2050. This scenario constrains annual capital spending and purchase of offsets.
