Biography

Dr Niyaz Ahmed is an academic bio-scientist, veterinarian and an Open Access advocate based in Hyderabad, India. He was graduated in Veterinary Medicine in 1995 and obtained further degrees in Animal Biotechnology (MS) and Molecular Medicine (PhD). Niyaz worked for the Centre for DNA Fingerprinting and Diagnostics (CDFD) for 10 years where he contributed extremely significantly to the mission of that centre through his association studies in molecular epidemiology since 1998 until he joined the University of Hyderabad in December 2008.

Niyaz leads a long-term open-ended program in Pathogen Biology at the University of Hyderabad and supervises a team of 7 PhD students and 2 post-doctoral fellows. Current research interests of his lab include diversity, evolution and biology of Mycobacterium tuberculosis and Helicobacter pylori in the context of evolution of survival mechanisms, acquisition and optimization of virulence, and their impact on dissemination dynamics, invasion, persistence, signaling events, molecular pathogenesis, strain evolution and prevention measures. To address these issues he uses a host of genomic and cellular microbiology approaches.

Amidst his busy research career Niyaz is an ardent supporter of the PLoS and BMC-lead contemporary approaches to Open Science, Open Access to Science and Open Evaluation of Science. He is a Section Editor (Microbiology and Genomics) of PLoS ONE and has overseen/handled peer review of dozens of landmark articles there. Niyaz is also associated with the International Society for Genomic and Evolutionary Microbiology and the European Helicobacter Study Group. More recently he has championed the cause of Gut Pathogens, a specialized Open Access journal of which he is an Editor-in-Chief.

Niyaz blogs at http://niyazahmed.blogspot.com - this blog site is primarily aimed at re-promoting and highlighting important Open Access content that has been published in PLoS ONE journal and the Gut Pathogens.
