Julie Shortridge is an assistant professor and extension specialist in the Department of Biological Systems Engineering at Virginia Tech. Her research focuses on making water resource systems more sustainable, robust, and resilient through the use of systems engineering methodologies, machine learning, simulation, and statistical modeling. In particular, she is interested in how complex water resource systems with engineered, natural, and human components can be proactively managed to address changes in climate, land use, and environmental policies over the short- and long-term. Shortridge is also interested in refining traditional methods for risk assessment and management so that they are better suited to emerging, “wicked” challenges such as climate change, invasive species, and emerging diseases.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Before joining the Global Change Center community, Shortridge completed her undergraduate research in Environmental Engineering Science at the University California, Berkeley, a Master’s in Engineering from Johns Hopkins University, followed by a Ph.D. in Geography and Environmental Engineering from Johns Hopkins. Prior to conducting her graduate studies, she spent six years working as an engineer focused on groundwater contamination and remediation, and as a consultant for the United Nations Environment Program on disaster preparedness.

During her time at Virginia Tech, Shortridge has collaborated with a number of GCC Affiliates including Drs. Anamaria Bukvic and Ryan Calder, who were recently part of a multi-institution study examining the current and future impacts that climate change will have on coastal lands and cities. Their Journal of Marine Science and Engineering article calls for improved communication efforts among scientists, stakeholders, policy makers, and minority and poor residents.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_single_image image=”58823″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][vc_column width=”1/2″][vc_single_image image=”58825″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Shortridge is also active in Virginia Cooperative Extension work, leading the Water, Irrigation, and Drainage section.

Microbial communities, or microbiomes, are central to life on earth. Nearly every habitat and organism hosts a diverse community of microbes forming their collective microbiome. Each day we walk through a vast invisible network of environmental microorganisms. And GCC Affiliate Frank Aylward’s research as led him to study microorganisms from both the land and the sea.

Aylward’s first interest in the interface of microbes, ecology, and evolution started in rural southern Arizona where he grew up. His interests led him to complete his undergraduate education at University of Arizona where he studied the origins of multicellular organisms using green algae. He then obtained a PhD in Microbiology from the University of Wisconsin-Madison where he researched the symbiotic relationship between leaf-cutter ants, cultivated “fungus gardens” where they procure their food, and the commensal microbial community that facilitates the system.

Returning his interests to the aquatic biosphere, Aylward joined the lab of famed marine microbiologist, Edward DeLong. Working at both the Massachusetts Institute of Technology and the University of Hawai’i at Mānoa, Aylward explored the ecological function of cyanobacteria in the open ocean and its importance as a marine keystone species.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Aylward joined the Virginia Tech and the Global Change Center (GCC) community in 2017, as assistant professor in the Department of Biological Sciences. Aylward’s current research broadly focuses on microbial diversity and genome evolution in multiple different microbial groups, including giant viruses, bacteriophages, and several lineages of bacteria and archaea.

In a 2020 Nature article, Aylward revealed the impact that large, double-stranded DNA viruses, or “giant viruses,” have on eukaryotic organisms and their ecosystems around the globe. “By introducing new genomic material into hosts, viruses can shape the evolution of cellular life through a process called endogenization,” said Aylward.

In an article published earlier that year,  Aylward found, “several giant virus genomes that encode genes typically only found in cells, some of which appear to be involved in metabolic processes,” he added. This work reveals the importance of viruses in eukaryotic evolution and portends what may happen to current species as climate change creates ecological pressure around the world. IGC Fellow and co-author of the study Alaina Weinheimer, is pursuing this line of inquiry further as part of her doctoral degree.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_single_image image=”58712″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][vc_column width=”1/2″][vc_single_image image=”58714″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]The Aylward Lab is also interested in examining the ecology and evolution of major bacterial and archaeal lineages across the Tree of Life through broad phylogenomic analysis. This research interest has led Alyward to collaborate with other members of the GCC community such as GCC Affiliates Jeb Barrett, Brian Badgley, and Brian Strahm, and IGC Alumnus Ernie Osburn. Together, they recently published a paper examining relationships of microbial diversity with ecosystem functioning in forest soil samples. Aylward was also part of the GCC Microbiome Working Group, and has co-led “Introduction to Microbial Community Analysis” along with other group members David Haak, Brian Badgley, and Lisa Belden since Spring 2019.

Since his time here, Aylward has garnered numerous awards such as the 2018 Alfred P. Sloan Research Fellowship in Ocean Sciences and the 2019 Simons Foundation Early Career Award in Marine Microbial Ecology and Evolution. Additionally, he is the primary investigator of an Infrastructure Innovation for Biological Research grant from the National Science Foundation (NSF).

Outside of research and academia, Aylward has taken part in outreach activities such as promoting the Virginia Tech Systems Biology at Blacksburg Community High School and participating as a judge at the 2018 Virginia Tech Research Day.  More recently, Aylward was featured in an episode of the podcast, Finding Genius, where he discussed the importance of studying giant viruses.

Mark your calendars, the Center for Communication Science will be celebrating its 5th anniversary with the annual Communicating Science Week! Taking place between March 16th through the 22nd of 2022, the week will showcase the efforts of faculty and graduate students from across multiple disciplines to connect with communities and address “wicked” problems our world faces.

The Nutshell Games, the center’s 90-second graduate student research talk competition, offers graduate students the opportunity to show off their communication skills and present their research to a public audience. With an emphasis on communicating to non-scientists, the Nutshell Games is judged by a diverse panel of people from Virginia Tech, the surrounding Blacksburg community, and beyond.

Since the first Nutshell Games in 2017, many IGC Fellows have participated and claimed wins. IGC Alumnus Dr. Max Ragozzino claimed top prize in 2017 with, “Emerald Ash Borer, and How We’re Stopping it with the Chestbuster from Alien.” The next year, Brenen Wynd finished in first place with a presentation focused on mass extinctions, “Almost All My Friends Are Dead.” Tyler Weiglein’s participation was also featured in an article highlighting communication workshops held before the competition.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/2″][vc_single_image image=”58585″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][vc_column width=”1/2″][vc_single_image image=”58599″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]And let’s not forget our most recent 2020 Nutshell winners. Last year, IGC Fellows Amber Wendler, Sara Teemer Richards, Abby Lewis, and now IGC Alumnus Dr. Bennett Grooms swept the competition in a 4-way tie for first place.

October 26, 2021

The microbiome has emerged as a fundamental component of all life on earth. For example, microbial communities are key in maintaining the health of plant, wildlife, and human hosts as well as mediating major biogeochemical cycles in most ecosystems. Thus, the ability to study microbiomes is an essential tool across many disciplines of not just biology, but also a variety of other fields relevant to global change.

Recognizing the importance of the subject, a collective of Global Change Center (GCC) faculty affiliates began meeting in 2018 to explore research synergies and opportunities to build upon existing strengths across campus.  The group discovered that while the number of labs delving into microbiome-related research was increasing, they were quickly outpacing the availability of relevant student training on campus. As a result, many graduate students interested in microbiome research did not have the background to apply appropriate methods. “Students working with their own ‘big data’ benefit immensely if they know how to leverage computing resources on campus to process and analyze the huge volumes of information from next generation sequencing of microbes” said GCC affiliate David Haak.

In an effort to fill this training gap, members of the GCC Microbiome Working Group combined their research experience to develop a graduate course in the Spring of 2019 titled “Introduction to Microbial Community Analysis”.  Collaboratively taught by GCC affiliates David Haak and Brian Badgley from the School of Plant and Environmental Sciences and Lisa Belden and Frank Aylward from the College of Science, ​the class provided graduate students working in environmental, engineered, and host-associated microbial systems with an understanding of modern tools available for analyzing microbial components of ecosystems and microbial community data.

Students were encouraged to analyze their own data to provide a hands-on educational experience within the context of their own research. Badgley noted, “the most fun aspect of this course is working with students who initially might be intimidated by microbiome research because of their background. As part of that process the students are also learning from the diverse perspectives they each bring from different disciplines and enriching the course beyond what we alone can provide.”[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column width=”1/4″][vc_single_image image=”35937″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][vc_column width=”1/4″][vc_single_image image=”35846″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][vc_column width=”1/4″][vc_single_image image=”33270″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][vc_column width=”1/4″][vc_single_image image=”40199″ img_size=”full” add_caption=”yes” alignment=”center”][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]Demand for this course was evident as enrollment exceeded the initial cap. Students enrolled hailed from five different graduate programs and four different colleges, with IGC Fellows representing approximately 70% of the group. The demand for the course resulted in it being taught again this fall 2021 semester, again with a broad representation of disciplines.

Faculty working groups formed under the GCC have spanned an array of topics to include the microbiome, invasive species, microplastics, environmental justice, ecological restoration, and freshwater salinization.  Groups typically coalesce around a problem or thematic topic of shared interest.  Most groups start by meeting frequently to develop relationships and an understanding of collective expertise.  After identifying shared goals, working groups have moved-on to hold workshops and small conferences, develop manuscripts, submit grant proposals, teach courses, and pursue training grants.
