I am an Assistant Professor at UT Austin in the Department of Geosciences. My students and I are already involved with many paleontological, geobiological, and sedimentological projects so please contact me if think you may be interested in joining the group. Check out specific projects and facilities on our website: www.jsg.utexas.edu/martindale/

I am primarily interested in marine paleoecology and the geobiology of carbon cycle perturbation events (e.g. mass extinctions, ocean anoxic events, and ocean acidification events in deep time). My research also includes carbonate sedimentology and the paleontology/paleobiology of reef builders (e.g corals and sponges). I am currently working on the Pliensbachian-Toarcian (Early Jurassic, ~183 Ma) reef crisis and Toarcian Ocean Anoxic Event. My doctoral research focused on the reef demise and extinction at the Triassic-Jurassic (T-J) boundary, which has been hypothesized to be an ocean acidification event caused by the rapid eruption of the Central Atlantic Magmatic Province and subsequent release of carbon dioxide. Extinction events, such as the Triassic-Jurassic, draw attention for their catastrophism, however, lesser extinction events can be just as interesting, particularly for resolving questions pertaining to species survival and ecosystem recovery. The Late Triassic and Early Jurassic events will help us understand what environmental conditions cause massive ecosystem collapse, and what conditions marine biota can survive. A large part of my research involves the study of Upper Triassic and Lower Jurassic reef ecosystems, the newly evolved scleractinian corals, and reef variations geographically and temporally. I have also begun research on an Early Jurassic Lagerstätte, which preserves both pelagic and benthic communities across the Toarcian Ocean Anoxic Event. In future work, I am interested in combining my research on ancient ocean carbon cycle perturbations and extinctions with research on modern reef decline and stressors that inhibit the secretion of calcareous skeleton.

Graduate Students

Anna M Weiss, Ph.D., expected 2019 (Supervisor)
I am a doctoral student in the Martindale lab. I received my undergraduate degree in Anthropology and Geology from Stony Brook University in 2013. My research focuses on biotic interactions and reef collapse during the PETM, specifically looking at the formation of novel reef ecosystems during this period. I am also a passionate environmentalist and hope that my work can add to a growing body of research that aims to better predict and mitigate the effects of climate change on modern reefs.

Selva M Marroquin, M.S., expected 2016 (Supervisor)

Chiara Tornabene, M.S., expected 2016 (Supervisor)
I'm is a second year Masters student working with Dr. Rowan Martindale. My current research aims to determine novel proxies to test for photosymbiosis in Mesozoic corals. Photosymbiosis is a mutualistic relationship between modern corals and dinoflagellates called zooxanthellae. Because zooxanthellae are not preserved in the fossil record, my research aims to define a quantitative proxy for ancient photosymbiosis using stable isotope geochemistry.

PhD Student (Graduate)
I am accepting applications for a new PhD Student in my lab. This student must be interested in paleontological or carbonate sedimentology research (both would be best), and should be aware of the current/recent projects in the Martindale Lab. Exceptional MSc students will be considered, but preference is for a doctoral student (prior research experience at the undergraduate or MSc level is desired).
