Nezar Al-hebshi, PhD

About

Associate Professor

Research Program

Dr. Nezar Al-hebshi is a Research Associate Professor at Tempe University Kornberg School of Dentistry where he co-directs of the newly established Oral Microbiome Research Laboratory.  He has extensive experience in the field of oral microbiology, namely characterizing the oral microbiome using real-time PCR and next generation sequencing (NGS). He, in collaboration with Dr. Tsute Chen at Forsyth Institute, recently developed an algorithm for classification of 16S rRNA NGS reads from oral microbial samples to the species level. Dr. Al-hebshi currently focuses on the study of bacterial and fungal communities (bacteriome and mycobiome, respectively) associated with oral squamous cell carcinoma (OSCC) as well as those found in ready-to-use smokeless tobacco products. His work with collaborators from USA, Australia, Sri Lanka, Saudi Arabia and Yemen provides the first epidemiological evidence for association of certain bacterial species, such as Fusobacterium nucleatum, Pseudomonas aeruginosa, campylobacter spp. and prevotella spp. with OSCC. His work also is the first to suggest presence of a proinflammatory microbial community within OSCC tissues. He is currently exploring this further using a metatranscriptomic approach.
