Since Fall 2017, I am an Assistant Professor in the School of Veterinary Medicine at the University of Wisconsin - Madison. My research combines field, genomic and computational approaches to the study and conservation of endangered mammals, focusing on the effects of human intervention in otherwise natural ecological and evolutionary processes. Non-human primates, and particularly orang-utans, are my primary taxa of focus. My Molecular Ecology and Evolution Laboratory hosts post-doctoral scientists, graduate students and numerous undergraduates, and is based in the Animal Health Center at the nearby Henry Vilas Zoo, integrating research, teaching and outreach with the University's wider community.
I originally trained in Zoology at the University of Aberdeen in Scotland, earning a Bachelor's degree (B.Sc. Hons, 2008) following study at the University of British Columbia (2006-2007) in Vancouver, Canada. For my honours thesis, I investigated the effects of forest disturbance on wild Bornean orang-utans and conducted line-transect surveys of orang-utan nests to re-determine population density in Tanjung Puting National Park, Indonesia. I then read for a Master's degree (M.Phil. by Research, 2010) in Biological Anthropological Science at Darwin College, University of Cambridge, England, where I inferred the subspecies composition of reintroduced orang-utans at Camp Leakey, in the same national park, and assessed their mitochondrial DNA diversity. I then completed a Ph.D. in Biological Anthropology (2013), also at the University of Cambridge, for which I performed genetic analyses of orang-utan social structure, mate choice and reproductive success, primarily determining the extent to which Kusasi — the dominant male at Camp Leakey for more than a decade — fathered offspring over socially subordinate, non-cheek-padded males. To date, I am one of only three Western scientists to earn their PhD wholly from studies of orang-utans at Camp Leakey, after its co-founder, Dr Biruté Galdikas (1978), and Dr Gary Shapiro (1985).
During my doctorate, I completed an 18-month residency in the Department of Primatology at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, before moving to the Department of Evolutionary Genetics as a post-doctoral scientist. I then joined the Chinese Academy of Sciences and Max Planck Society Partner Institute for Computational Biology in Shanghai, China, where I served three-and-a-half years as a post-doctoral fellow.

I am delighted to extend my research into 2018 with new grants from the Association of Zoos and Aquariums, with the renewed support of the Ronna Noel Charitable Trust, and with my third grant from the Arcus Foundation. My active grants exceed $250,000 through 2019.
My work has been especially well received by the media, particularly following publication of our study on male orang-utan bimaturism in September 2015, which was featured by The Washington Post, The Daily Mail, IFL Science and Serious Science, among more than 200 other outlets, plus by the German-language Leipziger Volkszeitung. Our 2016 manuscript on orang-utan subspecies hybridization was highlighted in the March print edition of Science magazine, covered separately online by ScienceShots, and featured by The Daily Mail and Mongabay, among others. My career as a scientist has been featured in Poland's national daily newspaper, Gazeta Wyborcza, in the Hebrew-language magazine, Mishpacha, and by Psychology Today magazine. In response to my collaborations with Chinese zoos, I was profiled in Chinese by The New York Times.
I currently Chair the Scientific Advisory Committee of the Orang Utan Republik Foundation, a California-registered 501(c)(3) (since 2013); serve on the Steering Committees of the Biomaterials Banking Advisory Group (since 2016) and the Molecular Data for Population Management Scientific Advisory Group (since 2018) of the Association of Zoos and Aquariums; and am Director and Trustee of The Orang-utan Conservation Genetics Trust, UK-registered charity number 1155284 (since 2013); among other advisory appointments. From 2009-2015, I taught on the faculty of 'The Cambridge Tradition' summer school with Oxbridge Academic Programs, teaching Zoology every July at Jesus College, Cambridge, and served on the subsequent French programme, 'The Paris Connection'. To my knowledge, I am the only Cambridge doctoral graduate with a thesis signed by Dolly Parton ("Well are you going to hold me, or that old book?"), and have strict rules on kiss-squeaking and nest-building in the laboratory.
My research combines field, genomic and computational approaches to the study and conservation of endangered mammals, focusing on the effects of human intervention in otherwise natural ecological and evolutionary processes. Non-human primates, particularly orang-utans, are my primary taxonomic focus. In response to declining wild populations, I have shifted focus — following eight years of fieldwork in Indonesian Borneo — to addressing the sustainability of these species ex-situ.
Having derived from a small number of wild-caught founders in the 1920s, concern is mounting that orang-utans in zoos — considered the 'backup' population in the event of in-situ extinction — are becoming increasingly inbred. Through whole genome and exome sequencing, RAD-Seq, and targeted baits assays, we have learned that zoo orang-utans are predominantly outbred, however, and are highly admixed between distinct species and subpopulations that diverged up to ~3.4 million years ago in the wild. Six manuscripts are now in preparation for publication, of which three are presently in review; these add to an earlier invited review for International Zoo Yearbook (2018). This long-term project has been supported with ~500,000 USD in extramural funds, principally from the National Natural Sciences Foundation of China (2014, 2015) and the Arcus Foundation (2016, 2017-2018). With further support from the Association of Zoos and Aquariums (2017-2018), we are now investigating if outbreeding results in outbreeding depression, in collaboration with Megan Elder, the Orangutan International Studbook Keeper, from Como Park Zoo and Conservatory. The work capitalizes on my collection of ~3,000 biomaterials from wild, ex-captive and zoo-housed orang-utans globally: among the largest biomaterials collections in the United States from a critically endangered mammal.
In collaboration with a consortium of orang-utan researchers, I performed line-transect surveys across Tanjung Puting National Park as part of a Borneo-wide census of the species. Pooled data from across the island led to publication of the 2016 Population and Habitat Viability Assessment, which guided the new 'Strategy and Orangutan Action Plan' (SRAK) of the government of the Republic of Indonesia. We found that only ~80,000 orang-utans are expected to remain on Borneo; fewer than ~15,000 are thought to exist on Sumatra. We later performed the first integrative trend analysis of a great ape species on Borneo, concluding that orang-utan populations have declined at a rate of 25% over the last 10 years (Scientific Reports, 2017). We have since determined that 100,000 orang-utans were potentially killed in the wild in just 17 years, from 1999-2015 (Current Biology, 2018). These findings led to a change in Bornean orang-utan conservation status, from 'Endangered' to 'Critically Endangered' in 2016. I recently re-assessed the population in Tanjung Puting National Park: in a manuscript currently under review (2018), I assert the Park as home to the largest contiguous population of wild orang-utans remaining on Borneo. My fieldwork was funded with ~60,000 USD in small grants.
In collaboration with Jennifer Taylor-Cousar of National Jewish Health, and with Garry Cutting and Neeraj Sharma of Johns Hopkins University, I am working to study potential genetic correlates of chronic respiratory disease (CRD) in great apes. Orang-utans have especially high incidence of CRD: around 18% of captive orang-utans are afflicted; the condition is the leading cause of death in adolescent individuals. Preliminary data are now presented in a manuscript currently under review, and will ideally serve as the precursor for a proposed larger and longer-term research programme. Since 2018, I am also working with The Great Ape Heart Project to analyze whole-genome sequences from great apes with cardiovascular disease. Preliminary data suggest a Mendelian inheritance pattern in certain instances of cardiac disease.
Bornean orang-utans comprise three geographically and reproductively isolated subspecies, yet nobody knew this in the 1970s at the dawn of orang-utan reintroduction programmes. In collaboration with Biruté Mary Galdikas of Simon Fraser University and Linda Vigilant of the Max Planck Institute for Evolutionary Anthropology, I investigated subspecies composition at Camp Leakey in Tanjung Puting National Park, Indonesia, finding that multiple subspecies were unwittingly reintroduced and have since had hybrid offspring that have further introgressed. The results were published in 2016 in the journal, Scientific Reports, in the context that reintroductions of displaced mammals may serve as de facto genetic translocations. Given the magnitude of potential ill effects, our findings were featured in the print edition of Science. I am staunchly opposed to such inter-breeding within wild populations, as the effects on health and reproductive success are not yet remotely understood.
Despite being one of the most prominent ornaments in the animal kingdom, the purpose of male orang-utan cheek pads is poorly understood. The theory that cheek pads make dominant males more attractive to females, and thus result in them fathering more offspring, is complicated in that subordinate, non-cheek-padded males are also able to achieve paternities. In collaboration with Biruté Mary Galdikas of Simon Fraser University and Linda Vigilant of the Max Planck Institute for Evolutionary Anthropology, I investigated male reproductive success in orang-utans at Camp Leakey in Tanjung Puting National Park, Indonesia, in the largest longitudinal orang-utan paternity study conducted to date, in-situ, in a single population. We concluded that male bimaturism is likely an evolutionarily stable reproductive strategy, in which unflanged males simply bide their time until periods of rank instability. Our findings were published in September 2015 in the journal, Behavioral Ecology and Sociobiology.
Having better elucidated the role of male orang-utan cheek pads (left), I am now keen to understand how and why they develop in the first place. In particular, I hope to determine the underlying psychoendoneurocrinological mechanism that might facilitate developmental suppression of subordinate males: it has long been theorised that dominant, cheek-padded male orang-utans are somehow able to inhibit cheek-pad development in younger rivals. In collaboration with Tom Goodwin of Hendrix College and Melanie Bond, formerly of Smithsonian's National Zoo, we are analysing cheek pad, sweat and urine samples using GC-MS to determine potential compounds that might be useful in chemical signalling and olfactory communication. This research was profiled in 2014 on PBS (US) and Channel 4 (UK) in the documentary series, Sex in the Wild: Orang-utans. Sample collection and analysis is ongoing in 2018, to expand on promising pilot data.
The success of orang-utan reintroduction programmes can be assessed on the basis of reproductive success — that is, if individuals survive and go on to have their own healthy and viable offspring. As part of a larger collaboration headed by Dr Noko Kuze, I contributed data from Camp Leakey in Tanjung Puting National Park, Republic of Indonesia, which I collected through fieldwork and via a meta-analysis that spanned multiple decades of reintroductions. The resulting paper, in the journal, Primates, was published in November 2012. Two other manuscripts on female orang-utan reproduction are in preparation or review as of 2018.
Since 2013, I have worked with more than 180 zoos across mainland China (where I am known as 林伊: Lín Yī) to assist in welfare, husbandry and management of all great apes. I proposed and now serve as Editor in Chief of the forthcoming Chinese-language Orang-utan Husbandry Manual, to which chapters have been contributed by zoo professionals across the United States and abroad. The Manual will shortly be published by the Chinese Academy of Sciences, the Chinese Association of Zoological Gardens and Nanjing Hongshan Forest Zoo. A similar manual for chimpanzees is now also in the early stages of preparation. In January 2017, I led a delegation of keepers from US zoos to facilitate a week-long workshop in chimpanzee and orang-utan care. Their visit served as a successful precursor to China's first National Orangutan Husbandry Workshop, which I have co-organized for October 2018.
My first book, 'The Kingfisher Encyclopedia of Life', was first published in the United Kingdom on 5 July 2012, by Macmillan. It was released in North America on 31 October 2012, and has since been translated and published in 13 languages in a further 16 territories: Russia, Slovakia, Colombia, Germany, Spain, Brazil, the Czech Republic, Poland, Portugal, Georgia, Turkey, Lebanon, Israel, Romania, Taiwan, and mainland China. The German-language edition, 'Leben!' ('Life!') was one of nine national finalists in the 'Perspectives' category for the 2013 Knowledge Book of the Year (Wissensbuch des Jahres) award in Germany, given by the magazine, Bild der Wissenschaft. The book was also nationally shortlisted in Austria in the junior-knowledge category for the 2013 Science Book of the Year award, given by the country's Federal Ministry for Science and Research. Booklist described the book as a "powerful interdisciplinary resource, encompassing lessons from biology, geography, natural history, and the social sciences." School Library Journal starred the book and concluded, "This work is a spectacular success." After five years of research, my second book — a popular-science guide to animal sex — is in preparation for publication.
"This book presents a jaw-dropping look at 30,000 years of biological evolution. Packed with the latest science, it is designed to engage readers emotionally - from a sense of astonishment that the mayfly can enjoy a full life in less time than it takes to read the book, to the awe that is inspired by trees over a thousand years old, to a sense of humble self-reflection when encountering colonies of simple life forms which have existed since before recorded time. At the heart of the book is the human story, examining the many and varied factors which influence our longevity. At the end, readers of all ages will emerge with a new sense of wonder at the natural world's amazing diversity, and a new appreciation for their own place among it."
