I am a new Assistant Professor at UT Austin (Fall 2014), while I get my UT website sorted out, please find information about my past, current, and future areas of research on my Harvard website: www.people.fas.harvard.edu/~rmartindale. I am looking for prospective undergraduate and graduate students to join my research group! The lab is already involved with many paleontological, geobiological, and sedimentological projects so please contact me if think you may be interested in joining the group.

I am primarily interested in reef paleoecology and the geobiology of carbon cycle perturbation events (e.g. ocean acidification 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. In future work, I am interested in combining my research on ancient ocean carbon cycle perturbations and reef extinctions with research on modern reef decline and stressors that inhibit the secretion of calcareous skeleton.

Areas of Expertise

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

Chiara Tornabene, M.S., expected 2016 (Supervisor)


MSc or PhD Student (Graduate)
I am actively seeking graduate students to join my lab who are interested in paleoecology, marine communities, carbonate sedimentology, and/or geobiology.
