What specific lung disease or respiratory issue are you interested in? What do you think might be the cause, mechanism, or potential treatment, and how will you test it?

Research existing studies on your chosen topic. Identify key players (molecules, cells, pathways) involved in the lung function or disease you’re studying.

Depending on your research question, you might utilize: In vitro models: Cell cultures that mimic lung tissue function; In vivo models: Animals like mice, rats, or guinea pigs with induced respiratory issues; Human studies: For specific stages of research, involving healthy volunteers or patients with respiratory conditions.

Develop experiments to test your hypothesis. This could involve exposing cells or animals to potential treatments, pollutants, or irritants and measuring various markers of lung function, inflammation, or injury.

Analyze the data you collect from your experiments. Look for patterns and statistically significant results to support or refute your hypothesis. This data will be used to draw conclusions and potentially inform future research directions.
