10th June 2019 – Chelsea Little, Eawag (Swiss Federal Institute of Aquatic Science and Technology)

Chelsea LittleHi there! I’m Chelsea Little. I just finished my PhD in Ecology at the University of Zurich, and during this time I was based at Eawag, the Swiss Federal Institute of Aquatic Science and Technology. I will start a postdoctoral research position at the University of British Columbia in the fall. My journey to where I am now included an REU project as an undergrad, a stint as a research technician, and an international Erasmus masters program in Europe, after a detour through semi-professional ski racing. There’s no one “right” path to becoming a scientist!

I have a hard time defining what kind of ecologist because I have worked in a lot of study systems and am interested in many different aspects of ecology and evolution. However, all of the research I do is related to community ecology. I use this and connect to ecosystem processing of carbon and nutrients, to evolutionary biology, and to applied topics like climate change and invasive species. My PhD work was with macroinvertebrate communities in the streams and rivers of Eastern Switzerland. Before that, I worked in plant communities in the subalpine zones of the Colorado Rockies and in northern Sweden, the oak savanna of the Pacific Northwestern U.S., the alpine zone of the Swiss Alps, and the tundra of Svalbard.  I’ve also worked with colleagues on experiments using protozoans in model communities, as well as gathering data from other researchers to use in meta-analyses and reviews. What aspects of ecology do you want to talk about? I’m excited to share my experience and to chat!

Outside of my working life, I am an avid runner, hiker, and cross-country skier – being outside is part of why I became an ecologist in the first place. I also love to travel, cook, and read lots of books. I’ll use part of my time as a host to discuss work-life balance, hobbies, outdoor adventures, grad school life, living outside your home country, and feminism in science.


6th May 2019 – Jesse Czekanski-Moir, SUNY-ESF (Syracuse, NY, USA) / Belau National Museum (Palau)

Jesse Czekanski-MoirHi! My name is Jesse Czekanski-Moir and I’m a Ph.D. candidate in Conservation Biology at the State University of New York College of Environmental Science and Forestry (SUNY-ESF) in Syracuse, NY, USA. The central projects of my Ph.D. include biogeography, community ecology, and evolutionary biology, especially of ants and land snails in Palau (Micronesia, Oceania). I’m also working on projects involving evolutionary simulations, ancient whole genome duplications in the Mollusca, and non-marine gastropod Phanerozoic diversity patterns. My Ph.D. advisor Rebecca Rundell and I will be co-leading a field course in Palau in a few weeks, so some of my tweets will likely involve fun facts about Palau biogeography, culture, and the conservation biology of invertebrates.

11th March 2019 – Hannah Brazeau, University of New Brunswick

Hannah Brazeau_2019I am a MSc student at the University of New Brunswick (Fredericton, NB, Canada) studying the effects of interspecific competition on pollinator-mediated selection of floral traits. More specifically, my thesis project uses fireweed to look at how floral traits associated with attraction of pollinators (such as floral scent) can change when an unrelated, highly attractiveplant species is growing nearby. This project allows me to combine concepts and methods used in plant community ecology, plant-pollinator interactions, and floral evolutionary biology, with a dash of chemistry thrown in for good measure.

Before starting my masters in Dr. Amy Parachnowitsch’s lab (@EvoEcoAmy on twitter), I completed my BSc in Biology at Algoma University (Sault Ste. Marie, ON, Canada). While at Algoma University, I completed an honours thesis on co-occurrence patterns and temporal stability in an old-field plant community under the supervision of Dr. Brandon Schamp (who now co-supervises my masters project). Prior to my BSc, I completed a three-year diploma in biotechnology at St. Lawrence College (Kingston, ON, Canada).

I’m a first generation student and particularly passionate about improving learning and research experiences for undergraduates, as well as communicating science through art. This will be my second time hosting Biotweeps, (previously hosted as @moietymouse) and I’m looking forward to talking to you all again!

15th October 2018 – Cassie Freund, Wake Forest University

Cassie FreundI am a PhD student at Wake Forest University. I study community ecology in tropical forests and my current research focuses on the role of a large natural disturbance, landslides, in shaping Andean montane forests. My research site is in and around Manu National Park, Peru, and I am part of the Andes Biodiversity and Ecosystem Research Group (www.andesconservation.org). I am particularly interested in how these forests regenerate after landslides, what this means for carbon storage of montane forests, and how landslides and climate change may interact in the future. My work integrates fieldwork, drone technology, and LiDAR (in collaboration with Dr. Greg Asner) to understand the role of landslides in Andean landscapes.

Prior to starting my PhD I worked in Indonesian Borneo for about five years, first doing research on tropical peat swamp forests and later as the program director of the Gunung Palung Orangutan Conservation Program. I’ve written or contributed to articles about topics ranging from microtopographic variation in peat swamp forests, to the orangutan trade, to ecosystem services! I will touch on many of these things during my week hosting Biotweeps. Finally, I also write popular science articles for Massive Science, and my articles can be found here: https://massivesci.com/people/cassie-freund/. My personal website is: https://cathrynfreund.wordpress.com/ and I usually tweet over at @CassieFreund.
