I received my Ph.D. in Geoscience from UC Riverside in 2020 under Dr. Gordon Love on Phanerozoic microbial transitions during extinction/climate events. After that, I had a stint as a postdoctoral associate of the Earth, Ocean, and Atmospheric Sciences Institute of Rutgers University, working under Dr. Kat Dawson on the biogeochemistry of tidal rivers. https://www.aaronmmartinez.org/contact daily 0.75 2024-09-27 https://images.squarespace-cdn.com/content/v1/61afc1175e347262f65f1caf/cd884e00-421a-4526-be1b-ca6e10f73fb0/SLM_Tle.jpg Contact - Oh, hey there!

The picture above shows preparative column chromatography to purify chemically distinct organic fractions for analysis - this allows us to determine what kind of organisms left behind their matter within these rocks! https://images.squarespace-cdn.com/content/v1/61afc1175e347262f65f1caf/caed7270-4973-4f7f-af9d-9010ff697e7e/Burrows_L.jpg Research - Mass Extinctions!
