Wilson Aruni

Assistant Professor


Dr.Wilson Aruni had joined the Loma Linda University from his native country India. He graduated in the field of Microbiology from Tamil Nadu Veterinary and Animal Sciences University (TANUVAS), Chennai, India and completed his doctoral studies during the year 1999 and on work deputation at the All India Institute of Medical Sciences, New Delhi where he specialized in the field of molecular virology and advanced imaging techniques. He started his career as Assistant Professor in TANUVAS and served as Associate professor in Microbiology since June 2009. He was on interm charge of the University Bioinformatics Centre and also for the Electron Microscopy facility. He is a recipient of Richard memorial award and Naidu memorial award conferred for his best research work. He was also the recipient of Young scientist award conferred by the Indian Science Congress, has two patents to his credit and authored three books in the field of Medical Microbiology and Biotechnology.

Dr.Wilson is presently involved in studying the molecular pathogenesis mechanism of two important oral pathogens Porphyromonas gingivalis and Filifactor alocis at Dr.Hansel Fletchers lab and also in teaching Bioinformatics.
