Dr Chisti focuses on paediatric respiratory and critical care medicines and coordinates large-scale studies across Bangladeshi hospitals. He currently leads several clinical trials such as “Bubble continuous positive airway pressure for children with severe pneumonia and hypoxaemia in Bangladesh” and “Etiology of pneumonia in severely malnourished children and their post-discharge follow-up”. He has also developed low cost life-saving innovations that were scaled for use in resource-limited settings. His research is multifaceted and looks at childhood pneumonia, tuberculosis, bronchiolitis, asthma, sepsis, malnutrition, enteric encephalopathy and diarrheal complications.  It is not well understood how TB impacts growth and survival in young children compared to other acute illnesses, or if there are metabolic derangements specific to pediatric TB. Dr Chisti leads a TB sub-study embedded within CHAIN which aims to answer these questions.
