Kristina McOmber
I grew up and attended undergrad in California, and started my Master's in May 2022 looking at the pre-breeding behavior and diet of Razorbills and Atlantic Puffins in the north Atlantic. In the past, I have worked with seabirds in the Gulf of Maine, the Bering Sea, and the eastern and central Pacific.
Katrina Wilcox (they/them)
Katrina joined the Davoren Lab in fall 2022 after completing a B.Sc. in biology at the University of Winnipeg with an honours thesis focused on the influence of foraging strategies of bird-window collision susceptibility. For their M.Sc., Katrina is investigating seabird vocalisations at deep water capelin spawning sites on the Newfoundland coast. Katrina is specifically interested in how the use of seabird vocalisations change within social and behavioural contexts.
Dr. Matthew Legard
Matthew completed his M.Sc. in 2017 at the University of Hull, UK where he studied the effects of personality in captive Gentoo penguins. He then worked as an aquarist at an aquarium, The Deep, before moving to Winnipeg to start a Ph.D. in the Davoren Lab at the start of 2021. He is interested in examining personality in populations of seabirds found in Newfoundland and how this effects things like foraging behaviour and breeding success.
Sierra Schlief
Hi, I'm Sierra! I'm from Bemidji, MN, and I moved to Canada to complete my Bachelor of Environmental Science at the University of Manitoba. I joined the Davoren lab in the fall of 2023 to start my master's. For my first chapter, I will determine if capelin beach spawning locations have site-specific chemical signatures based on larval capelin otolith microchemistry. My second chapter will examine sand lance otolith signatures to uncover their life-history traits.
Gibson Rieger
I joined the Davoren Lab in 2021, writing my honours thesis on predation and kleptoparasitism on Atlantic puffins by gulls at a seabird breeding colony. I completed my B.Sc. in Biological Sciences, majoring in Ecology & Environmental Biology with a minor in Microbiology, at the University of Manitoba in February 2023 and began work as an aquatic science technician with Fisheries and Oceans Canada at the Freshwater Institute in Winnipeg. Now continuing in the Davoren Lab, I started my M.Sc. in May 2023 looking at the diel behaviour of sand lance and mapping forage fish habitat on the Newfoundland coast.
