Research

Currently, I study the evolutionary genomics of human's closest living relatives, bonobos and chimpanzees, and human's closest—but now extinct—relatives, Denisovans and Neanderthals. Previously, I've studied the behavior, ecology, and health of captive and wild non-human primates as well as non-invasive monitoring of wild animal populations. Further information on these projects can be found below and on the Publications page.

Pan Evolutionary Genomics
Archaic Hominin Genomics
Human's closest living relatives, bonobos and chimpanzees, have remarkable genetic and phenotypic diversity making them important evolutionary models. However, reconstructing their evolutionary history is currently restricted to genomic data due to the scant chimpanzee fossil record. This research uses computational and machine learning approaches to better understand demography and positive selection in these taxa.

While many traits cannot be inferred from the fossil record, the advent of ancient DNA has opened a new path for understanding the biology of extinct taxa. Predicting the phenotypes of Denisovans and Neanderthals is also relevant because nearly all modern human genomes contain ancestry from one or both of these lineages. I recently reviewed what is known about archaic hominin phenotypes from genomic data and am currently studying alternative splicing.

Non-Invasive Population Monitoring
Primate Behavior, Ecology, and Health
Accurate estimates of population size and demography are important for understanding their biology and behavior as well as their conservation. I used genetic capture-recapture sampling and methods to assess a bonobo population in the Democratic Republic of Congo and a forest elephant population living in a human-modified landscape in Gabon.

My initial research focused on the behavior of captive primates, including hair plucking and manuel laterality in captive bonobos. I've also studied wild bonobos in the Democratic Republic of Congo. During my time at the University of Oregon, I helped mentor both undergraduates and graduate students on various primatology projects and collaborated on a project examining health biomarkers in captive gorillas.
