Hi there, my name is Lu

I am a NPP Postdoctoral Fellow at NASA Goddard Space Flight Center & Georgetown University.

My research is focused on astrobiology and the search for life in the universe. I use experimental and computational tools in combination with flight capable instruments like mass spectrometers to look for signatures of life on other planets, especially those that are not based on Terran biochemistry— or “life as we don’t know it”.

In my previous life as a graduate student, I focused on the characterizing the biogeochemistry of a hypersaline, subsurface environment in Antarctica: Lake Vida brine. I used multidisplinary tools, metabolomics, metagenomics, and geochemistry, to interrogate the production, evolution, and preservation of organic molecules in this environment. This work shed light on the potential habitability of similar environments on icy/ocean worlds and contributed to our understanding of biosignature preservation in cold-limited ecosystems.
