Ashutosh Kumar works as an Assistant Professor in the Division of Biological and Life Sciences, School of Arts and Sciences, Ahmedabad University, Gujarat, India. He obtained his Master's degree in Applied Microbiology from Vellore Institute of Technology, Vellore in 2008 and worked at CSIR-Indian Institute of Toxicology Research, Lucknow for his Doctorate degree and was involved in understanding the fate of nanomaterials on biological systems. His current research areas of interest includes, nanomedicines for cancer and arthritis therapy, DNA Biochip for pathogen detection, nanobased drug and gene delivery, nanoemulsions for food industries, environmental nanotechnology and nanotoxicology.

Ashutosh has established several new methods for nanomaterial toxicology in India. He developed a novel method for the detection of uptake of nanoparticles in live bacteria for several generations. He also unravelled the mechanism of metal oxide nanoparticles induced genotoxicity and apoptosis in prokaryotic as well as in eukaryotic cells using the state of art techniques such as flow cytometry, electron and confocal microscopy, biochemical enzyme assays, genomics and proteomics. The work conducted by him is in the frontiers of nanomaterial safety area worldwide. His studies shall have far reaching applications in predicting the adverse health effects of nanoparticles and safe use of ENMs to protect human and environmental health.

He has published more than 40 research papers and 12 book chapters in internationally reputed peer reviewed journals. He has received several national and international awards including the "INSA Medal For Young Scientist 2014” in the area of Health Sciences, NASI-Young Scientist Platinum Jubilee Award (2015) in the field of Bio-medical, Molecular Biology and Bio-technology, DBT Young Investigator Award, Ahmedabad University - Excellence in Research Award - 2015, among others for his scientific contributions. Dr. Tenguria is an active researcher and currently working as Project Scientist in Cedars-Sinai Medical Center, Los Angeles, CA USA. He has been actively involved in research and training of graduate and undergraduate students. He received his MSc in Life Sciences from University of Rajasthan, Jaipur and PhD in Biotechnology from University of Hyderabad, Hyderabad, India. He received his postdoctoral training from Purdue University, Indiana, USA and Cedars-Sinai Medical Center (UCLA), Los Angeles, California, USA. Currently, he is working in the area of molecular innate immunity to unravel molecular signaling mechanics for sensing danger (infectious pathogens) signals through cytosolic receptors of the innate immune system of human and mouse hosts. With his doctoral and postdoctoral fellowships and research in the area of host-microbe interactions, bacterial survival and pathogenesis, he made seminal contributions by publishing in international Jr (Cell Host-Microbe, Nature Commun, Frontiers).
