He has made important contributions in the area of integrated computational materials engineering (ICME) including reduced order representations for microstructure-process-property relationships, Markov random fields approach for microstructure reconstruction, and parallel, multiscale algorithms for optimizing deformation, fatigue, failure and oxidation response in polycrystalline alloys, high temperature ceramic matrix composites and energetic composites. He was awarded the 2010 NSF CAREER award, the 2012 DTRA Young Investigator Award, 2018 Defense innovation award and is an Associate Fellow of AIAA.
Vijaya Raghavan obtained his PhD (Agr Eng) from Colorado State University, his MSc (Agr Eng) from the University of Guelph, and his BEng (Mech Eng) from Bangalore University. He joined McGill in 1974 as a Research Associate in the Department of Agricultural Engineering, where he is presently a James McGill Professor. He was Departmental Chair from 1993 to 2004. His research is on post-harvest technologies related to drying, storage, and processing of foods. He has directed four CIDA-funded projects: Three on transfer of expertise and post-harvest technologies to southern India for the consolidation of food security, and one on transfer of expertise and electro-technologies to China for research into food processing and other applications. He directed one IRDC project on promoting use of millets in India. In 2012, he was inducted into the Royal Society of Canada (RSC), and into the National Academy of Agriculture Sciences (India) as a Foreign Fellow. He was President of the Canadian Society of Bioengineering (CSBE), and President of the Academy of Science of the RSC. He is currently the Director of the RSC. He was a member of the Food Expert Advisory Committee that provided informed advice to the Minister of Health.
The use of electro-technologies has led to other lines of study - MW-assisted extraction of bioactive compounds from plant materials, disinfestation of grains in storage using ultra-high frequency MWs, electro-osmotic dewatering, MW-assisted retting of flax and hemp for production of biofibers, and MW pasteurization of in-shell eggs. Recent research work has been on the effect of MW and other processing methods on the quality of the plant material being treated, i.e. on the longevity and germination of seeds dried using MW, and on protein structure which determine digestibility and allergenicity.
Research efforts over the last 10 years has also been directed at developing novel and methods for managing agricultural wastes that lessen the impact on the environment. Work has been done on the production and usage of biochar from waste plant and forestry biomass as a method of carbon sequestration while generating a material that has use as a soil amendment, the generation of electric energy by microbial fuel cells consuming organic wastes, and carbon capture from gas emissions and organic wastes by photosynthetic microorganisms. Recent projects have been on the use of cold plasma activated water to clean or sterilize leaf vegetables, thereby increasing their shelf life; and on hydrothermal carbonization of animals wastes (e.g. seafood wastes) to generate hydrochar which has potential use as a soil amendment or fertilizer, and as a cheap absorbent material. The overall research contribute towards circular economy leading towards food security and sustainability in food systems.
To date, the results of the work by his research group have generated over 650 papers in peer-reviewed journals, 55 book chapters, over 850 conference papers, and 7 patents, and have been applied with much success in the field in four CIDA-funded projects and one IDRC-funded project to address the issues of food security and safety in India. An estimated 30% of crops and produce in developing countries are lost after being harvested as a result of damage and spoilage. Losses occur at every step of the chain of events from the field to the market as a result of mishandling during sorting and transport, of poor storage conditions that leads to spoilage and infestation by insects and pests, and of inadequate packaging for market. Post-harvest losses are not only that of quantity but also of nutritional quality of the produce. Preventing or reclaiming these losses by implementing adequate storage methods and by processing the food would provide a means of addressing food insecurity problems, and also provide the resources to deal with problems of poverty, malnutrition, and hunger.

Algorithmic fairness is an area within AI that has generated a great deal of public and media interest. Despite being at a very early stage of his career, Raghavan has been one of the leading figures shaping the direction and focus of this line of research.
Raghavan received a BS degree in Electrical Engineering and Computer Science from the University of California, Berkeley, as well as MS and Ph.D. degrees in Computer Science from Cornell where he was advised by Jon Kleinberg, the Tisch University Professor of Computer Science and Information Science. Raghavan is currently a Postdoctoral Fellow at the Harvard Center for Research on Computation and Society. His primary interests lie in the application of computational techniques to domains of social concern, including algorithmic fairness and behavioral economics, with a particular focus on the use of algorithmic tools in the hiring pipeline.
Presented annually, the Doctoral Dissertation Award recognizes the best doctoral dissertation in computer science and engineering and is accompanied by a prize of $20,000. Dimitris Tsipras of Stanford University, Pratul Srinivasan of Google Research, and Benjamin Mildenhall of Google Research received Honorable Mention honors.
The work, which was published Thursday in Nature Communications, was conducted at the University of Central Florida, the Institute of Materials Research at the German Aerospace Center (DLR) and the Argonne National Laboratory near Chicago with the collaboration ofCleveland State University.
Seetha Raghavan, associate professor of mechanical and aerospace engineering at UCF, conceived of the highly challenging idea of monitoring the very thin layers of super strong coatings used to protect turbine blades as they are exposed to extreme conditions in order to get a clear understanding of how they fail.
The Argonne particle accelerator would be used to generate the high-energy X-Rays which would be deflected by the atoms in the coating material. By measuring the level of bending or diffraction, the scientists would be able to determine how the coating has been impacted by conditions.
Raghavan, who has been funded by the National Science Foundation for the last three years to study the durability of high temperature coatings, received an additional $52,000 as part of a Catalyzing New International Collaborations award from the agency to support the experiment and international collaboration.
In June 2012, Raghavan and her graduate students Kevin Knipe and Albert Manero travelled to Cologne, Germany where the students spent two months working with the DLR team to design the compact furnace and coat the turbine blade material to develop specimens to be tested. In November, the team reunited outside Chicago at the Argonne laboratory to conduct the synchrotron X-ray studies.
After four days of round-the-clock testing, the team collected a terabyte of raw data, revealing some areas of previously undetectable strain, which are expounded on in the Nature Communications piece.
Raghavan said she hopes the research will be used by turbine manufacturers to verify their testing results, develop new simulation models and ultimately help them better predict any potential failure.
Other participants in the project included Sanna Siddiqui of UCF and Carla Meid and Janine Wischek of DLR. The work was additionally supported by the German Science Foundation and the U.S. Department of Energy.
The food processing industry generates enormous quantities of waste every year. On top of this, the way that food is processed can have negative impacts on the health of consumers. Therefore, it is vitally important to develop new food processing methods that consider human health while producing minimal waste. Dr Vijaya Raghavan and his research group at McGill University, Montreal, have been applying their expertise in chemistry and engineering to develop and optimise food processing techniques, to ensure the future health of people and the environment.
Today, almost all of the food we consume has been processed in some way. Food processing methods offer a range of important benefits, such as extending shelf life, and providing foods that are more palatable or edible than their unprocessed counterparts.
Without food processing, the needs of urban populations would be difficult to fulfil, and our selection of foods would be extremely limited, particularly in winter. However, certain aspects of food processing raise concerns over both environmental sustainability and the health of consumers.
For example, the food processing industry generates a phenomenal amount of waste each year, both in terms of packaging materials and wasted food. On top of this, different processing methods can alter food on a chemical level, which can lead to negative health impacts. To address these issues, Dr Vijaya Raghavan and his research team at McGill University have been investigating various aspects of the food processing industry, in order to develop and optimise methods.
