Current Students

Gen Morinaga

September 2012 - Present

Gen is broadly interested in convergent evolution, or the evolution of similar traits among distantly related organisms. His research in particular focuses on the evolution of snake-like body shape among lizards, and how this body shape affects ecology and locomotion.


Amy Cheu

August 2015 - Present

Amy is interested in how multiple phenotypes affect multiple aspects of performance by examining the complex relationships between interacting traits and their functions in an organism. She is currently working with basilisk lizards and integrating functional morphology, comparative biomechanics, muscle physiology, and statistics.

Faye Harwell

January 2014 - Present

Faye is a MS student studying how body temperature and hydration affect jumping performance in three species of frogs. To compare the three species, she has collected field data, preference trials, and jumping performance trials that focus on temperature and moisture preferences. From these three sets of data, she will compare the three species to evaluate whether amphibian species are affected by their evolutionary history or ecological niche in relation to temperature and moisture preferences. Faye is interested in ecology and evolution, and plans on continuing in graduate studies after completing her MS.


Marian Crockett

May 2014 - Present

Marian is an undergrad and future MS student interested in animal locomotion and how environmental variation affects how an animal runs and their sprint performance. She records lizards running on large-particled granular substrates (rocks and balls) with high-speed video to see effects of the size and shape of the particles on performance and kinematics. The outcomes of this experiment can inform us about the ways animals navigate obstacles and how they change their speed or modify how they run when faced with different substrates. This can give biological insights into robotics, technology, and physics of running on a variable surface, all from looking at lizards running in slow motion!


Erika Schaper

September 2014 - Present

Erika works as a lab assistant caring for the reptiles and amphibians used for research in the lab. She is also planning to embark on a course of study investigating the microhabitat use of native Philippines skinks. By quantitatively analyzing the living and non-living components of their environment, she hopes to draw conclusions about their morphological adaptations as well as their degree of habitat preference.


Muhaj Azeez

May 2015 - Present

Muhaj is a BA student interested in working with diffreent types of lizards to understand their locomotion. She is very interested in how different morphologies and habitats affect the locomotion of the animal.


Rob Holden

May 2015 - Present

Rob works on the animal locomotion and behavior. He is comparing swimming and running on water performance in basilisk lizards.


David Berry

September 2015 - Present

David is using mechanical models to study how head shape affects burrowing performance. The mechanical models represent the range of diversity of head shapes that have evolved in burrowing lizards. The models allow David to manipulate the diameter, slope of the snout, and how pointy the snout is independently. He uses the models to study how these variables affect how easily the model heads can penetrate different substrates.


Jordan Majka

January 2016 - Present

Jordan is working with lizards and frogs seeing how they move using their limbs. He is looking at form and function: how their physical traits affect their performance. He is also trying to elucidate how multiple physical traits affect locomotor performance.
