While I am not able to attend the AAPA meetings in Austin this year, I am still pleased to be there in scientific spirit as a co-author on an excellent poster during the Saturday afternoon session: Primate Evolution and Anatomy. Please stop by and check out our work on dental variation in New World monkeys!
Here we are in the Spring semester! I had an amazing time teaching IB35AC, Human Biological Variation, last semester. Being at the head of a 300 person class was an incredible experience that gave me great insight into the intricacies of teaching such a large course. I am really grateful for all of the support I received from Dr. Hlusko and my five GSIs.
This Spring has been packed with activities. Just last night, I gave an invited DeCal lecture on “Medical Secrets” for a course at the intersection of journalism and public health. And I have a great lecture planned for the Marin Science Seminar next week. Other than that, it’s been all working on manuscripts, all the time. Big announcement coming soon on my plans for next year!
After teaching a smaller version of the course this summer, I am very excited to be head instructor of IB35AC, a 300 student class on human biological variation, this fall. IB35AC is a lower-level class that fulfills the American Cultures component of the undergraduate degree at UC Berkeley, a breadth requirement unique to UC Berkeley that asks all students to explore the ethnic and racial variation within the United States from a comparative perspective. This course also addresses human biological variation, including phenotypes like skin pigmentation, intelligence, sex, and gender, from biomedical, anthropological, and evolutionary perspectives. A key goal of this class is to help students understand the role of both biological and cultural components of human variation in the evolution of our species.
I am happy to announce that I have finished my PhD program at UC Berkeley. Yippeeee!!! It’s been an amazing 5 years in the Integrative Biology program, but I am ready to enjoy life as a doctor. Don’t worry – I’m not disappearing. I will be lecturing here at Cal this summer as head instructor of IB 35ac – Human Biological Variation. Then, it’s on to a postdoc!
I am happy to announce that I have received the Outstanding Graduate Student Instructor Award from University of California, Berkeley for my work in IB 131, Anatomy Lab, and IB 140, Human Reproduction. It is an honor to be recognized amidst the numerous outstanding graduate student instructors on campus. I will be attending the award ceremony on May 2nd at I-House; I will be sure and post a picture from the event!
I am happy to announce that our paper on fossil primate cranial variation is out in the open-access journal Palaeontologia Electronica. The article, titled “Patterns of craniofacial variation and taxonomic diversity in the South African Cercopithecidae fossil record”, uses a sample of 99 fossil primate crania from South Africa, as well as more than 80 extant primates, to investigate the morphological and taxonomic diversity of South African fossil monkeys. The abstract is presented below, and the full pdf is available online.
The rich paleontological record of South Africa is central in our understanding of Plio-Pleistocene mammalian evolution due in large part to the number of crania recovered. Because of the difficulty of chronometric control in many of the cave systems from which these fossils derive, extinct Old World Monkeys (OWMs) are often employed as biochronological markers, making the taxonomic identification of these primate remains particularly relevant to pursuing broader evolutionary questions relating to human evolution and faunal diversity shifts. The taxonomic relationships for the OWM fossils are reconstructed through phylogenetic systematics that rely heavily on craniodental traits. These analytical methods assume that these characters are developmentally, functionally, and genetically independent. This assumption is increasingly being questioned by analyses of extant phenotypic datasets and genetics. We statistically explored cranial variation in South African fossil papionins (n = 99) to determine whether or not extinct taxa reflect the same phenotypic covariance structure as has been reported for extant OWMs. Our results show that many of the cranial measurements are statistically significantly correlated and fail to distinguish between species or even genera of fossil papionins despite distinguishing extant species. Overall, our results suggest that these extinct OWM taxa cannot be discriminated using craniofacial measurements alone, or that the taxonomic designations, as they currently stand, are confounded.
I recently re-discovered this poster for my talk at Let’s Have An Awesome Time Doing Science (2015), and I wanted to share it here. It was such a great event, and I was so honored to speak alongside so many influential scientists. And what a great poster, right?!
I am very excited and honored to be featured in the new UC Berkeley Koret Visitor Center up at Memorial Stadium! The exhibit features my work, and my outreach with The Graduates radio show on KALX. If you are in Berkeley, head up campus to see the exhibit featuring me, and several other graduate students, including two other scientists from the Department of Integrative Biology.
I am excited to be back after a 5 week trip to Ethiopia this summer where I was looking at Pleistocene cercopithecids at the National Museum in Addis Ababa. I was also lucky enough to see a bit of the country. All in all, it was a very fun and productive trip!
