Niyaz Ahmed, a noted biotechnologist, has been appointed Senior Director, Laboratory Sciences and Services Division, at the International Centre for Diarrhoeal Disease Research, Dhaka in Bangladesh. Atna_icddrb2 present the Head of the Department of Biotechnology & Bioinformatics, University of Hyderabad (UoH), he recently won the Shanti Swarup Bhatnagar Award. His tenure will be for a period of three years. Ahmed joined the Institute on November 1.

Established in 1960s as the South-East Asia Treaty Organisation (SEATO) Cholera Research Laboratory, the Centre is committed to solving public health problems facing low and middle income countries through innovative scientific research, including laboratory-based, clinical, epidemiological and health systems research.

Its mandate is to develop, test and assess the implementation of interventions specifically designed for resource-poor settings. It is funded by international core donors, Canada (Department of Foreign Affairs, Trade and Development), Sweden (Sida), the United Kingdom (DFID) and also by the Government of Bangladesh.

Niyaz Ahmed’s work is known in the area of infectious disease epidemiology and pathogen biology, including studies on multiple drug resistance in pathogenic bacteria, such as those causing TB and diarrhoeal diseases.
