Prof. Raj is engaged into two areas of research: (i) Flash Sintering and Related Phenomena, and (ii) Polymer Derived Ceramics (PDCs). He collaborates actively with institutions and Germany and Italy in both areas. He was invited for a two week visit to four laboratories in Germany who are engaged in research related to Flash Sintering: Juelich, Duisburg, Hamburg, and Goettingen. Graduate students from these institutions have spent extended periods in his laboratory. They work along side four graduate students and one post-doc. The work on PDCs is supported by the five-year PIRE-NSF program. This work is related to additive manufacturing of ceramic matrix composites, with relevance to next generation gas turbine engines and to the growing activities collectively called “Hypersonics”. The research on Flash Sintering, which was discovered in his laboratory is expanding into a new field of research. The original paper, published in 2010 was cited more than 100 times in 2019.
