Research opportunities in the Biology department

Phytoplankton physiology (Dr. Doug Campbell,
We study the ecophysiology of phytoplankton, with particular emphases on photosystem II and the Photosystem II inactivation/regeneration cycle,  resource allocations and Phytoplankton physiologyanalyses of the costs of growth and acclimation to environmental variation and new, integrative approaches to quantify and analyze these processes. We publish actively, collaborate widely, welcome short-term research visitors and welcome applications from qualified post-doctoral, graduate and undergraduate researchers.

Neurophysiology (Dr. Karen Crosby,
We study the neurobiology of appetite, impact of stress on feeding circuitry in the brain, endocannabinoid and nitric oxide signaling and regulation of food intake in the rat, and the role of the dorsomedial hypothalamus in integrating satiety and stress signals.

The Crosby Laboratory is looking for a graduate student or postdoctoral fellow to begin in September 2017 to study how stress affects an appetite-regulatory center in the rat brain using patch clamp electrophysiology.  If interested, please contact Karen Crosby (

Environmental animal physiology (Dr. Suzie Currie, shark
My research program is focused on understanding the feedback between behavioural and physiological responses allowing animals to compensate and maintain function in changing, often stressful environments. My research uses fish as models to determine how this phenotypic integration could lead to stress resistance. Over the past few years, we have been focused on thermal physiology and behaviour, dominance hierarchies, exposure to toxicants, and salinity stress. We study a range of animals including sharks, elephant fish, skate, Atlantic salmon, rainbow trout, hagfish, mangrove rivulus, killifish and seals.



Fish ecology (Dr. Matt Litvak,
We study fish ecology, behaviour and ecophysiology, spatial ecology and modelling, conservation, aquaculture and gene banking. 

Molecular genetics
(Dr. Vett Lloyd,
My research interests are in genetics and epigenetics with a focus on epigenetics disease, including cancer, Lyme and other Tick dragging tick-vectored diseases. Current projects include tick genetics, endobacteria and Lyme disease in wildlife, companion animals, and humans.

 Marine Botany (Dr. Irena Kaczmarska,
I am interested in evolution of diatoms, particularly in their deep divergences. The overriding objective of our work is to evaluate the evolutionary significance of diatom sex and related structures to better understand what role various types of sexuality might S. Clay Steell sampling at St. Andrews NBhave played in the spectacular diversification of diatoms since their appearance in the Jurassic Period. We infer relatedness between the groups of interest using standard molecular and cellular development approaches. Advanced microscopical techniques detect and localize opaline silica and visualize the fine structure of the cell-wall components during their stages of development. Anyone interested in unlocking the great potentials hidden in the very small things is encouraged to inquire.


Field ecology
(Dr. Diana Hamilton,
Research in my lab is focused on shorebird ecology and intertidal ecology, with attention paid to community-level interactions between birds and invertebrates, and interactions within invertebrate communities. My current research centres on movement, Bird watchinghabitat use, and diet of migrating shorebirds in Maritime Canada. We make extensive use of radiotracking technology and regularly band and flag several species of shorebirds in the field. We couple that with lab-based analyses of prey availability from samples collected in the field, stable isotope analysis of blood, and molecular sexing of birds to better understand the activities of shorebirds in this region.  I collaborate in this work with researchers from Environment and Climate Change Canada and the University of New Brunswick.
