Lively's research interests encompass a range of topics including energy-efficient separation processes, advanced
membrane technologies, and the development of high-performance polymers and microporous materials. His notable work, as co-author of the article "Seven chemical separations to change the world" in the journal
Nature, highlights the potential of purifying mixtures without using heat to lower
global energy use and
emissions. He has further contributed to the field with his work on "From water to organics in membrane separations" published in Nature Materials. Additionally, Lively has made advancements in the field of organic liquid separation, as demonstrated in his co-authored Science papers, "Reverse osmosis molecular differentiation of organic liquids using carbon molecular sieve membranes", "N-Aryl–linked spirocyclic polymers for membrane separations of complex hydrocarbon mixtures" , and "Fluorine-rich poly(arylene amine) membranes for the separation of liquid aliphatic compounds". == Awards and recognition ==
