Hi, I’m Ari!

I’m a marine sensory biologist exploring how animals make sense of their world (and occasionally photographing them while they study me back).

I explore how animals gather and use information to navigate uncertain, noisy, and rapidly changing environments. My work sits at the intersection of sensory biology, morphology, behaviour, physiology, and the messy beauty of ecological reality. I’m fascinated by how tiny structures—antennae and microscopic hairs like sensilla—and sensory processes shape information acquisition, decision-making, and biological performance, ultimately influencing how animals cope with ecological change.

I founded The Crab Lab as a space to explore these ideas and to help students and collaborators grow into confident, curious researchers. Whether I’m piecing together the morphological diversity of crustacean claws, running experiments on information gathering, or crouched over a tide pool with freezing toes and a macro lens trained on a watchful goby, I try to bring the same things to my work: attention to detail, curiosity, and a sense of humour about the chaos of being a biologist.

Research

My research explores how animals gather, process, and use information, with a focus on crustaceans and other marine invertebrates. From claws and sensilla to behaviour and physiology, my work uncovers how information drives decision-making and shapes ecological outcomes.

The Crab Lab

The Crab Lab is my research platform for studying sensory biology, morphology, and information ecology in marine invertebrates. It also serves as a training and mentorship hub for students who want to gain authentic research experience during their undergraduate journey.

From the tide pools to lab benches, photography offers a visual record of all the small worlds that keep me endlessly curious.
