Welcome to my personal site! Here you will find a brief description of some of my research interests, ongoing projects, tools I find useful or interesting for my line of work, links to some collaborators, and various other things. This is my first foray into website building, so please bear with me as I continue to learn and experiment. If you have any comments, suggestions, or questions please feel free to send me an email!

Research Interests

Habitat Ecology
I’m fascinated by the fundamental question of how the largest creatures on the planet make a living off of some of the smallest. The disparity of scales makes the baleen whale and its zooplankton prey subject to dramatically different physical realities, but the two are inextricably linked; in order to feed the whale must have complete mastery of the ocean dynamics that aggregate their tiny prey. What these conditions are and how whales find them drive my curisity and research forward.

Acoustic Ecology
Whales live in a sonic environment; they interact with their surroundings with sound as we do with light. Scientists exploit whales’ vocal prowess to find them, and, in some cases, better understand certain aspects of their ecology, behaviour, health, culture, and more. Passive acoustic monitoring provides an array of incredibly valuable research tools. I am interested in using and refining these tools for studying baleen whale ecology, as well as evaluating the risk that increasing anthropogenic noise poses to whales and our ability to monitor them.

About this site

This site is generated using R Markdown and is hosted for free via GitHub Pages. It’s not perfect, but I’ve thoroughly enjoyed putting the site together and appreciate the control and flexibility that this platform provides. You can find all the source code here. I’ve also posted links to many of the resources I used to figure out how to build this site on my resources page. Shoot me an email if you have any questions.
