Making Waves: Dr. Erin Hotchkiss

Making Waves is the podcast of the Society for Freshwater Science

Ep. 26: Carbon Fates, Dr. Erin Hotchkiss

Erin Hotchkiss

This month's podcast features 2017 Hynes Award winner Dr. Erin Hotchkiss discussing her work on the fate of carbon in aquatic ecosystems.

Dr. Erin Hotchkiss is an ecosystem ecologist who uses empirical data and statistical models to understand how land-water interactions and ecosystem processes shape the transport, transformation, and fate of carbon and nutrients in freshwater ecosystems. She uses a combination of monitoring (chemistry, hydrology, biology), experimental (manipulating carbon and nutrients, stable isotope tracers), and quantitative (Bayesian, inverse modeling) approaches to study freshwater ecosystem processes. Erin is an Assistant Professor in the Department of Biological Sciences at Virginia Tech, where she is also a member of the "Stream Team" and a faculty affiliate of the Global Change Center.

Her research focuses on the role of disturbance in shaping the taxonomic and functional composition of stream insect communities in mountainous regions ranging from Colorado's Rocky Mountains to Ecuador's Andes.


About Making Waves


We aim to disseminate current research in the aquatic sciences to a general audience through a semi-monthly podcast as well as other interactive. Our goal is to frame recent high-profile research papers or career achievements in the broader context of current environmental and scientific issues. Our focus is to follow and expand on the new mission of the Society for Freshwater Science in covering all types of ground-breaking research that is relevant aquatic systems. We hope to interview a wide variety of scientists ranging from graduate students to tenured professors from a diversity of countries and backgrounds. We will not focus solely on the research, but also on the story of the researcher. We feel it is both important and interesting to discuss with the researcher how they came to this point in their career and how they came upon the idea of the research being featured. We would additionally like to discuss other unique outreach activities related to the research that the investigators may be involved in.

The views expressed in the podcast are those of the interviewee and do not necessarily reflect the consensus opinion of the general SFS membership.


The podcast will be released every other month beginning in the fall of 2012. A new podcast will be released on the 15th of each month. Individual podcasts will vary in length but will generally be 15-30 minutes long. Each podcast will be accompanied by associated media (e.g. links to papers discussed, videos related to the research, and/or a discussion forum). Podcasts will be made available as mp3s and through the SFS YouTube channel.

Interested in participating?

We are actively seeking scientists who wish to share their stories on this podcast. This is an excellent opportunity to share your work with a wide audience! If you are interested, please send an email to sfspodcast@gmail.com including a brief statement of why you are interested in profiling your work. We are especially interested in covering recent high-profile research, but will consider any compelling story. You do not need to be a member of SFS to participate.


The Making Waves podcast would like to acknowledge facilities support from Arizona State University and the University of Washington.
