Jane Hill, Ph.D

Principal Investigator

Contact: email:

Education: Ph.D. Yale University, B.S. Rensselaer Polytechnic Institute

Research: Using breath to diagnose disease; molecular signaling within and between species.

Biography: Jane grew up in rural New South Wales, Australia. Her high school years were spent in Grenfell, the birthplace of the famous Australian poet Henry Lawson. After moving to the US and finishing a BS in Chemical Engineering and technical MBA (both at Rensselaer), she ran a small bioremediation company in central New York State for a few years. However, she wanted to know more about the microorganisms that underpinned the transformations of pollutants in the soil. So, she completed her PhD at Yale University with Water Treatment Technologist Menachem Elimelech and then worked with Biotechnologist Jordan Peccia at Yale for her post-doctoral experience. She spent over a decade measuring and evaluating how organic phosphorus compounds were cycled in the environment before turning her attention to infectious diseases and metabolomics. In her spare time, Jane likes to play tennis, hike with her dog, garden, skijor, read books and poetry, play music, travel ... and ponder microbes. When possible, she would like to continue learning how to kitesurf ... even though it scares her half to death.
