Dr Abu Sufian Chowdhury is a clinical researcher from Bangladesh with both quantitative and qualitative research experience. He is the Clinical Research Coordinator overseeing the clinical researches across TLMI-B.

Dr Sufian completed his Bachelor’s in Medicine and Bachelor’s in Surgery (MBBS) from Rangpur Medical College in Bangladesh in 2012. He is completing his Master of Public Health (MPH) theses from North South University of Bangladesh. After qualifying as a doctor, Dr Sufian worked at LAMB Hospital as a Medical Officer before starting work in The Leprosy Mission International-Bangladesh (TLMI-B) Rural Health Program in 2017. Alongside his work as a field medical officer, he worked on a number of studies including MALTALEP, IDEAL, COLEP and COCOA.

Currently, he is the co-PI on four international, multi-centre studies, both seeking to stop the transmission of leprosy:

  1. The INDIGO study, which is being conducted in collaboration with two Dutch research institutions - Erasmus MC and Leiden University Medical Center (LUMC). The INDIGO study seeks to develop and trial a leprosy diagnostic test using human leprosy biomarkers.
  2. The 2Bornot2B study, conducted in partnership with LUMC and TLM-Nepal, is designed to investigate the involvement of B-cells and antibodies in leprosy and M. leprae infection, using innovative research tools and functional immunoassays.
  3. Stop Transmission of Leprosy: PEP++ study, carried out in collaboration with NLR, seeks to halt the transmission of M. leprae in the designated project intervention areas.
  4. Extra-Clofazimine Study, conducted in partnership with Bombay Leprosy Project (BLP), is a clinical trial evaluating the use of clofazimine among multibacillary patients at high risk of developing Erythema Nodosum Leprosum (ENL) reaction.
