  Who Am I?

I am a PhD student in the Interdepartmental Doctoral Program in Anthropological Sciences (IDPAS) at Stony Brook University. I completed my Master of Research degree in Tropical Forest Ecology at Imperial College London in October of 2017, and my Bachelor of Science degree in Zoology at the University of St Andrews in June of 2016. I am originally from the North Fork of Long Island, New York. My research interests are broad and include evolutionary biology, behavioural ecology, biological anthropology, and statistical computing with R.

Recent Research Experience

Presently 'In the Lab'
I am working on my PhD dissertation proposal, which aims to better understand how brain size and brain organization have coevolved with behavioural ecology (i.e. habitat, diet, life history, sociality, etc.) among primates and other mammals.
This research is in conjunction with the Smaers Lab. (https://smaerslab.com)

​
Madagascar - 2017 to 2019
My masters thesis entitled "Does anthropogenic disturbance affect the diversity and size of seeds dispersed by lemurs?" was completed in August of 2017. For this research project I collected faecal samples from four diurnal lemur species in Ranomafana National Park across a gradient of anthropogenic disturbance.

I also led a short expedition to the recently-discovered Analamary-Ivohiboro Forest  to collect ring-tailed lemur faecal samples. I extracted the seeds from the faeces in order to better understand Lemur catta seed dispersal. This research is exciting as it is one of the first studies of L. catta  in a humid rainforest environment (this species ordinarily inhabits dry deciduous forests, spiny bush, and scrublands). 

I have presented some of my research at the inaugural meeting of the Malagasy Primatological Society in Tamatave, Madagascar in December of 2017, at the International Primatological Society’s 27th Congress in Nairobi, Kenya in August of 2018, and most recently at the Association for Tropical Biology and Conservation's 56th Annual Congress in Antananarivo, Madagascar in July of 2019.

​I have also recently returned from a second expedition to the Analamary-Ivohiboro rainforest in July of 2019 collecting faecal samples from the ring-tailed lemurs for a collaborative microbial project. 


Malaysian Borneo - 2017
The Stability of Altered Forest Ecosystems (SAFE) project is one of the world's largest ongoing ecological experiments. I took part on a 3-week field course which involved the taxonomic ID of plants, vertebrates, and invertebrates, and involved hands-on experience designing, collecting, and handling ecological, biogeochemical, and biodiversity data. I received valuable experience conducting research in both the secondary and primary rainforest environments.   

South Africa - 2015
For my undergraduate dissertation research at the University of St Andrews, I collected data in the Greater Kruger National Park on African elephant (Loxodonta africana) damage to woody plants. Trees and shrubs were identified to the species, and damage to them was scored through time to investigate their role as ecosystem engineers in the bushveld.
