Currently, she is working on mosquitoes for her PhD, specifically on studying the effects of habitat change on the movement of mosquito populations.
When not in the lab, Huiqing enjoys reading, doing a bit of art and playing tsum tsum. She hopes to see hummingbirds one day.
Yen Yi Tan
Yen Yi obtained her Bachelor’s degree in Environmental Studies from the National University of Singapore in 2017 and a Master of Research degree from Imperial College London in 2018. Her patriotic desire to contribute to Singapore’s avian research motivated her return to NUS to pursue her PhD in September 2019.
Intrigued by the avian migration phenomenon and the chubby appeal of plovers, Yen Yi hopes to combine these two interests in her PhD project, where she aims to study the population genetics of Common Redshanks (Tringa totanus) and elucidate its migratory strategy in genetic detail using Next Generation Sequencing. She is also currently working on a population genetics project studying Lesser Sand Plovers (Charadrius mongolus).
Yen Yi’s conflicting loves for snacks and fitness have resulted in a well-stocked desk space, from which she altruistically distributes food to her lab mates in desperate attempts to alleviate her calorific addictions. In her free time, she can usually be found Googling pictures of her favourite plover the Piping Plover (Charadrius melodus), playing basketball, and planning her next bird banding holiday.
Movin Nyanasengeran
Movin joins the Avian Evolution Lab as a PhD student in 2020. Coming from a background in research, consulting and conservation he aims to ground his research on the regional wildlife trade in a manner that allows it to have real-world impact.
When not doing research, Movin can be found wandering remote areas of the region, binoculars round his neck, chasing birds. He also maintains a strong interest in freshwater fishes and keeps and (attempts to) breed a number of species.
Mohammad Irham
Mohammad Irham obtained his bachelor’s from the University of Padjadjaran, Indonesia. He continued for a master’s degree at the University of Amsterdam, the Netherlands.

Research Assistants
Geraldine Lee
Geraldine is currently doing a Honours project on the challenging Locustella complexes. These are a group of grasshopper-warblers in Wallacea which are morphologically nearly indistinguishable in field. She is analysing bioacoustic data to reassess their taxonomic classification and flag cryptic species.
Geraldine hopes to one day whistle competently enough to communicate with birds.
Keita Sin
Keita is working on a project to cast light onto the complicated phylogeny of Asian flycatchers, in particular those from the genus Muscicapa. Generally referred to as “little brown jobs” by birdwatchers, humans struggle to identify them in the field. The birds, however, are able to tell each other apart, and he hopes to unravel the history behind their speciation.
His favourite bird so far is the Pacific Swift (Apus pacificus), but he is sometimes unfaithful when Needletails (Hirundapus sp.) fly by.
Undergraduates
Wei Xuan
Wei Xuan is an honours student currently working on investigating the dawn choruses of Little Spiderhunters (Arachnothera longirostra) in Singapore and Brunei. By analysing bioacoustic data, he hopes to detect if there is a regional variation in activity patterns and breeding seasons of Little Spiderhunters in the two regions.
Wei Xuan hopes to one day backpack through South America and aspires to be able to speak Spanish as well as the natives (hopefully).
Bryan Soh
Bryan is an Environmental Studies student and is currently working on investigating the genomic patterns of the Palearctic migratory shorebird, the common redshank (Tringa totanus). By using Next Generation Sequencing and analysing the genomic patterns across a time frame, he aims to discuss the changes over time and apply it to conservation genomics.
Bryan has developed his love for animals since young and hopes to help animals in the future through conservation. In his free time, he enjoys drawing and going down the YouTube rabbit hole.
Alumni
Keren Sadanandan
Keren did her honours project in the Avian Evolution Lab. She used mitochondrial markers to look at the population genetics of the Near-Threatened Short-tailed Babbler (Pellorneum malaccense) in Singapore. Her results showed fragmentation between sub-populations of Short-tailed Babbler in Northern and Southern Central Catchment Nature Reserve and showed that the population in Singapore was genetically impoverished in contrast to a comparable population from Borneo.
Keren worked as an RA in the lab, where she is involved in multiple projects including the resolution of swiftlet phylogeny, discovery of the Northern Boobook as a winter migrant to Singapore and the identification of retrotransposons in avian genomes. She loves Chinese food and sniffing Tiger Balm. Keren is now doing her PhD at Max Planck Institute for Ornithology, where she is now doing functional work on Aerodramus swiftlets. She is still collaborating with the Avian Evolution Lab for this project.
Grace Tang
Grace investigated the population genetics of the Olive-winged Bulbul (Pycnonotus plumosus) in Singapore, and sought to determine the levels of genetic diversity and connectivity present in the population. Fieldwork was done to collect samples from across Singapore and three mitochondrial genes (COI, ND2 and cyt-b) were sequenced and analysed. Results were heartening as they showed very high genetic diversity and potentially high levels of gene flow within the population.
She is currently working at the Bird Park as a Junior Avian Management Officer.
Nathaniel Ng
Nathaniel pursued his PhD degree in the Avian EvolutionLab. He obtained his Bachelor’s degree (Life Science) from theNational University of Singapore in 2008, then subsequently obtained his Masters degree in Environmental Science and Management from the University of California (Santa Barbara) in2013.
Nathaniel utilizes bioacoustics and Next Generation Sequencing techniques to investigate how recent earth history has affected the divergence, evolution, and biogeography of the avifauna of Wallacea. Wallacea, besides being one of the world’s most tectonically-active regions, has also been profoundly affected by sea level fluctuations caused by Pleistocene glaciation events that have occurred throughout the past 2.8 million years. These fluctuations have resulted in the repeated formation and disappearance of land bridges between landmasses here. By gathering a wealth of information from across whole bird genomes and by analyzing bird vocalizations, Nathaniel investigates the evolutionary mechanisms that have resulted in modern-day Wallacean bird diversity.
In his free time, Nathaniel loves exercising, singing in the shower, and dreaming about a world in which chocolate does not make people fat.
Gabriel Low
Gabriel studied introduced Javan Mynas (Acridotheres javanicus) in Singapore for his Honours thesis using Next Generation Sequencing (NGS) techniques, and was able to to determine that while they had a nearly panmictic population genomic signature, local Mynas appeared to breed locally and disperse globally.
He was working as a Research Assistant at the Insect Diversity Lab at NUS, applying NGS techniques on local bee populations in the genera Xylocopa, Amegilla, and Thyreus, but is now back with the birds
Gabriel relishes getting out of the lab and into the field to look for the weird, unknown, and beautiful. And he wants to learn to play the guitar. He is currently doing his PhD at Monash University, Australia.
Yan Ming Tan
Yan Ming worked on the evolutionary relationships of the endangered Black Partridge (Melanoperdix niger) and Long-billed Partridge (Rhizothera longirostris) as the relationships of these 2 poorly known species remain contentious. However, since DNA materials of these shy and elusive species have never been collected, this study was done using the ancient DNA extracted from the Lee Kong Chian Natural History Museum’s specimens.
He was a honours student under A/P Song Jian Xing, researching the molecular mechanism of the TDP-43causing Amyotrophic Lateral Sclerosis. The highlight of Yan Ming’s life was his solo trip to Nepal and India, trekking mountains and panicking big time when he got lost. He also aspires to be the strongest powerlifter in Singapore although he knows that will never happen.
Fatma Gözde Cilingir
Gözde (aka Gogo the Turtle Saver) is highly interested in the real-world conservation potential & applications of genomic research. Currently she’s working on one of the rarest turtle species in the World, Myanmar-endemic Burmese roofed turtle (Batagur trivittata). In addition to being rare, it is one of the least studied species as well. By using genomic level information, she tries to 1)estimate the number of breeders left in the wild 2)understand their mating behaviours 3) determine the population substructure in order to define conservation units for potential reintroductions and assurance colony management. Gözde has solid positive science background, but she has deep interests in social science theory of conservation and development, which would be the critical aspect for moving toward more environmentally and socially sustainable projects and policies. Besides being a young scientist, she sometimes transforms into Burmese roofed turtle named as Ms BooBoo.
Helen Nash
The aim of Helen’s PhD is to help create a more informative picture of the distribution and genetic variability of pangolin species found in Asia to inform conservation management goals. Specifically, she has been working on Sunda and Chinese pangolins (Manis javanica and M. pentadactyla), which are difficult to study in the wild, as they are nocturnal and shy of humans.
Her first project made use of local ecological knowledge in Hainan, China, to investigate status and threats of Chinese pangolin. Her second project uses next-generation sequencing to investigate genetic population structure of Sunda pangolin across SE Asia, which might potentially be useful for forensic monitoring of illegal pangolin trade. Thirdly, she uses VHF and GPS tags to understand dispersal movement, home range and habitat selection of Sunda pangolin in Singapore. All these varied layers of research will contribute to informed conservation action planning at both local and international levels.
Helen enjoys travelling and exploring new places during her free time.
Gwee Chyi Yin
Chyiyin first dipped into avian research with her Honours thesis on the Ninox boobook complex. Using a combination of bioacoustic and genetic data, she uncovered cryptic diversity in other groups of birds while working as a Research Assistant in the lab. She has a broad interest in evolutionary biology, including how speciation occurs across time and under varying climatic factors.
Chyiyin loves Kākāpō and was lucky enough to have met Sirocco. She has moved to Germany to pursue a PhD at LMU.
Soo Yun Jing
Yun Jing was an honours student working on a project on the conservation of the Siamese Crocodile (Crocodylus siamensis). The Siamese Crocodiles are listed as ‘Critically Endangered’, and there have been many on-going conservation efforts to preserve the species. Yun Jing’s project aims to identify potential pure-bred Siamese crocodiles from captive individuals in the Cambodian crocodile farms for a captive breeding programme using the Next Generation Sequencing method.
Elize Ng
Elize has broad interest in conservation and landscape genomics. She is currently investigating the effects of fragmentation on the population genomics of 23local bird populations through the use of Next-Generation Sequencing techniques and landscape genomic methods. Through her study, she hopes to assess areas that are corridors or barriers to gene flow and advice on landscape management.
Prior to her current project, Elize studied the population structure of the White-rumped Shama (Copsychus malabaricus) in Singapore using Next-Generation Sequencing. Prized for its melodious song, the Shama is regionally threatened b ythe caged bird trade –including Singapore where it is Critically Endangered. She found that the birds on the main Island of Singapore are largely comprised of captive birds that originate from Malaysia, highlighting the impacts of local bird trade on local bird populations.
She has also worked on a separate project, investigating the species limits of an Indo-Pacific Cuckoo Dove (Macropygia amboinensis) species complex with bioacoustic. The study revealed multiple cryptic lineages that are bioacoustically distinct and proposed for their elevation to species level. During her vacation, she enjoys traveling to seek the best of food and nature.
Balaji Chattopadhyay
Balaji has a broad interest in understanding the evolution of natural populations under changing climatic regimes, both earth-historic and human mediated. The present age of human domination, or the Anthropocene is characterized by drastic environmental degradation and associated climate change. However, we are yet to fully comprehend the consequences of this dramatic change for the existing wildlife. Balaji has provided one of the first evidence of Anthropocene mediated population endangerment of urban wildlife; assisted and opened new avenues for genomically informed field-based conservation efforts of endangered populations. He performs a broad spectrum of biodiversity and conservation research in South and Southeast Asia, specifically using integrative approach and high throughput genome scale data. In his free time, he enjoys long discussions over tea, photography, hiking, good food and lots of anime.
Kritika Garg
Kritika’s main interests are in understanding the role of gene flow in speciation. Gene flow is a pervasive micro evolutionary factor which can homogenize effect of isolation. It is not only important for maintaining connectivity between populations but also for acquiring novel traits via interspecific gene flow. Using birds as a model system she is investigating the role of gene flow in speciation using both population genomic and phylogenomic approaches.
Currently she is working on island biogeography and the effect of Pleistocene glaciation cycles on population connectivity in Sulawesi. In addition to this she is also studying the effect of elevation gradient on population structure in scrubwrens. Varying selection pressure across an elevational gradient can lead to local adaptation, population differentiation and subsequently speciation. Kritika is an artist and enjoys painting.
Emilie Cros
Emilie has abroad interest in evolutionary biology with a particularly keen interest in the study of acoustic communication. She graduated with a Masters degree in Ethology from University Paris XIII (France).During the past10 years, she took the opportunity to study acoustic communication in different model systems, as well as to further expand her skills for the study of evolution.
She joined the Avian Evolution Lab for her PhD. She used vocal and genome-wide data to investigate the emergence and loss of phenotypic and genomic diversity in sylvioids of Southeast Asia. She is currently working on a population genomic project on dogs.

This majestic myna species has been identified by the Asian Songbird Crisis Summit team as being in urgent need of conservation action within the Sunda region. He hopes to assess the impact of the caged-bird trade on local populations and inform conservation efforts both locally and regionally.
Dominic is perpetually restless and hungry, and unsurprisingly spends most of his time seeking novelty. He enjoys being outside, physical activity, eating, languages and culture (though not all at the same time).
Bryan Lim
Bryan was working on the phylogenetic resolution of the Oriental White-eye (Zosterops palpebrosus) species complex in Sundaland using Next-Generation-Sequencing. Bryan’s aim is to identify genetically distinct subspecies within the complex and their regional conservation implications as this species are highly poached in the regional cage bird trade.
In his free time, Bryan just enjoys birding right on his hall’s rooftop with a cold beer in hand.
Lim Jia Ying
Jia Ying was working on the rock pigeons (Columba livia) in Singapore, which is perceived to be a pest bird species. This invasive species seems to be thriving in our urban habitat, irking some citizens. She looks into the population assessment and behaviors (nesting, roosting, food source establishment) of the rock pigeons, of which may aid with developing a strategy to manage their population. She aspires to pass on the enthusiasm for Singapore’s biodiversity to those around her.
Ng Shao Hua
Shao Hua was working on a UROPS project on the population estimation of a wide-spread native bird in Singapore. He is conducting island-wide surveys to gather their population sizes across the nation and also at specific localities.
