ISEM Postdoctoral Scholars

Dr. Timothy Scott Myers

I am currently a Postdoctoral Scholar through ISEM in the Shuler Museum of Paleontology at Southern Methodist University. My primary research interests are paleoclimatology and paleoecology. I use both sedimentology and geochemistry to reconstruct paleoenvironments and provide detailed paleoclimatic information that is essential to understanding fossils in a broader ecological context. My current research involves using geochemical techniques to estimate precipitation, temperature, and primary productivity in Mesozoic terrestrial environments and determine the effect of these different paleoclimate factors on the ancient flora and fauna. I am also studying the effects of large-scale global climate events on low-latitude shallow marine and coastal environments in the Early Cenozoic. Working in the Angolan province of Cabinda in equatorial West Africa, I am using the oxygen-isotope values of fossil shark teeth to develop a high-resolution record of ocean temperature for comparison with global paleoclimate signals.  Scott Myers

Dr. Yuri Kimura

I am a vertebrate paleontologist. My primary area of research interests is to understand evolutionary adaptation of morphological traits in relation to climate change and effects of ecological competitions for resources in speciation, utilizing geochemical and paleontological tools. I focus on fossil rodents as research materials because the nature of fast evolutionary rates due to short life of rodents, in addition to occupation in a wide diversity of ecological niches, makes themselves ideal materials for my ecological research interests. I am currently working on fossil species of Murinae (Old World mice and rats) and Cricetidae (New World mice and rats) discovered from the Miocene Siwalik Group of northern Pakistan. I expect that these fossils tell us about how resource competitions between closely-related species or between distantly-related species play roles in adaptive change of dental morphology in ecological vulnerable animals.
