Postdoctoral Fellow

Blair is an ecophysiologist, geneticist, and marine biologist with a particular interest in sea turtles, fish and sharks. He grew up in Perth, Western Australia where living in close proximity to some of the world’s most pristine ecosystems inspired him to pursue a career studying wildlife. Blair’s research focus revolves around the impact of climate change and species conservation. He completed a Bachelor’s degree with first-class honours at the University of Western Australia (UWA) in 2012, with his honour’s thesis exploring the population genetic connectivity of a reef-associated fish species. Following this, he spent a year in South Africa as a Field Specialist monitoring the populations of many marine species, before returning to Perth to complete a vacation studentship on the molecular response of sea turtle embryos to thermal stress at the CSIRO. Blair completed his PhD in 2018 at UWA supervised by Dr Nicola Mitchell, where he explored the impacts of climate change on sea turtle development, focussing on modelling sex ratio shifts and mortality under rising temperatures as a part of WAMSI Kimberley node projects. He then completed an Endeavour Postdoctoral Research Fellowship with Dr Jeanette Wyneken at Florida Atlantic University (FAU) investigating the survival costs of turtle shell morphological anomalies. Blair commenced his Postdoctoral Fellowship at UMass, Amherst with Dr Lisa Komoroske in mid-2020, working remotely from Perth due to the pandemic. His project will explore relatedness and kinship in a Brazilian green turtle population through whole-genome sequencing, with a focus on understanding resilience to climate change through mating systems. Until he can get to Brazil, he is also working on the conservation genomics of the leatherback sea turtle.

Lab Alumni

Dr. Amy Teffer
Postdoctoral Fellow

Amy is a fisheries biologist, disease ecologist, conservationist, and mom. She grew up in western Mass but has spent time in Chicago, IL and British Columbia. Her research is conservation-driven and generally uses genetic tools to examine disease dynamics in wild fish populations. She received her PhD in Biology from the University of Victoria in BC studying the effects of climate change (warming) and fisheries capture-and-release on Pacific salmon immune responses, physiology, and pathogen dynamics during spawning migration. Her MSc research at UMass, Amherst examined the trophic ecology and eco-toxicology of large pelagic fishes in the Northwest Atlantic Ocean. As a post-doctoral fellow (in collaboration with Dr. Kristi Miller at DFO, Dr. Scott Hinch at UBC, and the Pacific Salmon Foundation), she has investigated how pathogens and oceanographic factors impact sockeye salmon productivity by reducing marine survival-this work integrates molecular tools with modeling approaches to investigate population-level responses over a 10-year period. As part of the 2019 class of David H. Smith Conservation Research Fellows, starting in July 2019 she will be working with Dr. Lisa Komoroske and Dr. Ben Letcher (USGS Conte Anadromous Fish Laboratory) to characterize the disease ecology of improving watershed connectivity. This project will use genetic sequencing and population modeling to identify how improvements to watershed connectivity (e.g., dam removal) impact pathogen transmission and disease processes of wild fish in a warming climate

Dr. Joshua Lonthair Joshua-photo
Postdoctoral Fellow

Joshua studies fish physiology, development and biochemical processes. He is a travel enthusiast and has lived all over the world, including Cuba, Japan, Florida, Mississippi, and most recently Texas. His research is rooted in attempting to understand the impacts on marine species that result from global climate change, and the mechanisms that are altered using genetic, biochemical, and whole animal tools. His PhD research at the University of Texas at Austin – Marine Science Institute focused on investigating the acid-base physiology of an estuarine teleost, red drum (Sciaenops ocellatus), with broader interests in understanding how individuals to populations exhibit differences in plasticity and resilience to external changes in environment. Specifically, why do some “win” while others “lose” in response to environmental change. In August 2019, Joshua will start as a postdoctoral research fellow in the lab investigating the impacts of temperature on physiological scaling, in collaboration with Drs. Nicholas Wegner (NOAA SWFSC) and Nann Fangue (UC Davis). He will be using a long-term grow out technique to test a “hot-topic” hypothesis in the field: the gill-oxygen limitation theory (GOLT). His research will integrate morphometrics, whole animal respirometry, gill surface area, and biochemical assays to understand how gill surface area or other mechanisms can limit maximum body size in an economically important fishery species, the Pacific sardine (Sardinops sagax caerulea). This project is supported by California Sea Grant and the Ocean Protection Council.
