My primary research focuses on the evolution and biogeography of invertebrate animals. In the lab we use genomic, transcriptomic, and morphological data from living and extinct animals to better understand evolution. A large body of of work focuses on arthropods and mollusks, but we also investigate many other groups of invertebrates, including velvet onychophorans, nemerteans, platyhelminths, annelids, and the so-called “minor phyla”. Current NSF-funded projects include Collaborative Research: The Opiliones of New Zealand: Revisionary synthesis and application of species delimitation for testing biogeographic hypotheses.

Katherine Angier, Graduate Student

 

K.A. Prof. PicMy research is on the ecology and evolution of social invertebrates, with a focus on termites. I am studying how Central African rainforest termites adapted to savanna conditions. Using phylogenetics and behavioral ecology, I will explore the evolution of traits to cope with wider temperature ranges, lower humidity, and fire. Termites are key ecosystem engineers in the tropics, and I am also interested in their positive and negative effects on agriculture. As a lifelong lover of invertebrate diversity, I enjoy teaching, fieldwork, and the intersection of science and art.

Shahan Derkarabetian, Postdoctoral Fellow

 
Shahan My primary interest is in the arachnid order Opiliones (more commonly called harvestmen) where I focus on the systematics and evolution of Laniatores, the most diverse harvestmen suborder. As a systematist, I have an interest in systematic methodology including phylogenetics, species delimitation, morphometrics, integrative taxonomy, and in particular molecular systematic methods. In this regard I utilize various next-generation sequencing and bioinformatic methods as tools to explore the evolution of harvestmen. In addition, all things to do with the evolution of cave taxa interests me, particularly the evolution and genetics of convergent cave-adaptive morphology.
 
 
 
 
 
 
 
 
 

Jonas Geburzi, Postdoctoral Fellow

 
JonasI study marine biodiversity, focusing on the question how climate change, species introductions and other human impacts affect coastal ecosystems. In particular, I am interested in changes of the genetic diversity and biogeography of coastal species that were caused by such impacts. My favourite research organisms are the true crabs (Brachyura), but I also work with other marine invertebrates. In the Giribet lab, I investigate genomic signatures of a century-long range expansion related to climate change, by comparing present-day and historical museum specimen of the Mangrove tree crab Aratus pisonii.
 
 
 
 
 
 
 
 

Whitney Preisser, EO Wilson Postdoctoral Fellow

 

I am a parasite ecologist and my research focuses on characterizing parasite biodiversity. I investigate spatial and temporal patterns of parasite diversity and describe this diversity in understudied vertebrate hosts. Here at the MCZ, I dive into the ichthyology collections and dissect fluid-preserved fish specimens to collect their parasites. I characterize the parasite communities of benthic and deep sea fish species and I will find and describe trematode species new to science.

Paula Rodriguez Flores, EO Wilson Postdoctoral Fellow

 

Paula Rodriguez FloresMy research focuses in different aspects of arthropod evolution, biogeography and systematics. I am particularly interested in characterizing major patterns of biodiversity within a fascinating group of marine crustaceans, the squat lobsters, as a critical step towards understanding evolutionary patterns across marine ecosystems. Only one third of squat lobsters diversity is currently known, so I work on the taxonomy of the group, describing new species, as an essential task to understand their evolutionary pathways. I pursue to investigate patterns of morphological and molecular evolution over time and the tempo and mode of diversification of squat lobsters from different depths.

Aaron Hartmann, Research Associate in Instruction and Research

 
aaron_hartmannI study marine ecology and conservation, primarily in coral reef ecosystems. I am particularly interested in how early life history strategies influence environmental tolerance, the evolution of mutualist symbiont transmission modes, how human impacts on the ocean influence coral offspring survival, and how metabolites diversify in marine communities. Through my research I try to understand how coral reefs and other coastal ecosystems will fare in the face of ongoing environmental change and generate tools to mitigate these impacts.
 
 
 
 
 
 
 
 
 
 

Arianna Lord, Graduate Student

 
Photo Arianna LordI am interested in the evolutionary history and global distribution of biological diversity. What factors underlie the origin, distribution, and diversity of invertebrate groups, and how do Earth and environmental processes affect them? I use genomic and phylogenetic techniques to investigate these questions and better understand some of the most fascinating, and perhaps misunderstood, animals in the tree of life. Originally from New Zealand, I received my Bachelor of Science from Yale University with a concentration in Geobiology and Paleontology.  I love natural history, science communication, and being out in the field.

Arachnophobes beware! Spiders can live in colonies of hundreds of individuals that prey and maintain webs together. How does this happen? Shoyo, a Cantabridgian, received his bachelor’s in biology from Boston University and is now working in collaboration with the Jordan Lab at the Max Planck Institute of Ornithology’s Department of Collective Behavior to study the phylogeny and communication of social spiders.
 
 
 
 
 
 
 

 

 

 

Leyla Ewald, Undergraduate Student

 
leyla_ewald_headshotI am a Sophomore at the College, passionate about marine biology and environmental science. I am concentrating in Integrative Biology, hopefully with a secondary in Energy & Environment. I am interested in how climate change affects the oceans, particularly how warming temperatures affect coral reefs through coral bleaching and how corals can evolve and become more resilient. I am happy to be working with Aaron Hartmann on his research comparing the genetic diversity of coral reef populations.

I am a senior at the college studying Integrative Biology.  In the Giribet Lab I study the phylogenetics of Polydesmida, the most diverse order of millipedes, using molecular and (in the future) morphological approaches.  Through this project, I am hoping to improve our understanding of the diversification and biogeography of this group. I am passionate about conservation and all things arthropod.  In my free time, I enjoy wildlife photography (IG: bugstagraham) and spending time outdoors.

I am a senior in the college, originally from Kenya, interested in applying phylogenetic and biogeographic methods to investigate questions related to invertebrate ecology and conservation. Currently I am working on a thesis focused on the New Zealand armored harvestmen genus Algidia. Outside of research, I am passionate about expanding access to the outdoors and to science.
