Research Interests

Developmental Innervation of brown adipose tissue (McMaster University, PDF)

BAT activation in neonatal mice

BAT sympathetic innervation pattern is controlled in part by neurotrophic factors secreted by brown adipocyte cells (aka ‘batokines’). We are trying to understand which factors are important in different populations of rodents

Developmental and maternal adaptation to high altitude (PhD Thesis, McMaster University)

Juvenile deer mouse at the summit of Mount Blue Sky, CO ~4300 m above sea level

For my PhD I studied high altitude populations of the North American deer mouse. I focused on the ontogeny of thermoregulation and how thermoregulatory systems are shaped by hypoxia and cold. Additionally, I studied maternal care and energetics.

Developmental responses to hypoxia in fish (MSc U Guelph)

Three-day-old zebrafish embryos. STEVEN J. BASKAUF HTTP://BIOIMAGES.VANDERBILT.EDU/

I’ve looked at some of the short and long term consequences of early exposure to low oxygen during critical windows of development.

Key Papers

Comparative physiology in extreme environments

I’m also generally interested in how animals cope with stressful environments. Some of my favourite critters to study include

Mangrove rivulus (Kryptolebias marmoratus)- these amphibious fishes live in environments that can be acidic, hypercapnic, hypoxic and hot…all at the same time! North American deer mouse (Peromyscus maniculatus)- broadest distribution of any North American mammal. Great models for studying local adaptation The White Footed mouse (P. leucopus)- close cousin of the deer mouse. live sympatrically in many locations but only found at low altitude Zebrafish (Danio rerio) -important model organism and super hypoxia tolerant Spiny dogfish shark (Squalus acanthias)
