Professor Junaid Haider's research lab specializes in sustainable bioproduction processes, with a focus on developing energy-efficient methods for the microbial synthesis and purification of high-value chemicals such as 2,3-butanediol. The lab integrates metabolic engineering, process optimization, and advanced separation technologies to enhance yield and reduce energy consumption in biomanufacturing. A key research direction involves designing novel extraction techniques to replace conventional, energy-intensive purification steps, thereby improving the commercial viability of bio-based fuels and chemicals. The lab also explores the integration of systems biology and process engineering to enable scalable and environmentally sustainable bioprocesses.

2,3-Butanediol has attracted interest as a promising drop-in fuel, mainly due to its high antiknock index and high heating value. Microbial production of 2,3-butanediol is considered more environmentally friendly and sustainable than chemical-based production methods. However, to achieve the 99% purity required for use as fuel, the dehydration and purification steps associated with the microbial production process consume tremendous amounts of energy. This high energy consumption limits the feas
