Ajay Kumar, PhD
I am a postdoc fellow in the laboratory of Dr. Cheong-Hee Chang. I have done my Ph. D in Microbiology from India, and two and half year postdoc in Microbiology and Immunology, Wayne State University, Detroit, USA. I have joined the Department of Microbiology and Immunology in the University of Michigan in February, 2016. My main research interests are to find the metabolism in innate T cells and demonstrate that how they are different from conventional T cells. I have publications in the field of Microbiology and Immunology in reputed Journals. My short term goals are to publish papers in reputed journals and get a postdoctoral grant which is available for international students.
