I am a bioengineering undergraduate exploring how biological engineering can combat climate change. During my undergraduate placement at Cyanocapture, a biotech startup using cyanobacteria to capture CO2, I proposed a method for continuous growth analysis to enhance cyanobacterial cultivation efficiency. I designed a biosensor for continuous optical density measurement that does not require sample dilution. I have so far developed a prototype to test operating principles and am working towards a calibrated sensor for feasibility analysis. By improving the growth sensing, I hope to increase cultivation efficiency and in turn carbon capture.
