"Biology of RNA end modification and repair"

RNA end modification and repair enzymes are important for cells to cope with RNA damage. But the substrates and products of RNA end modification enzymes are largely unknown and we continue to identify new targets of RNA repair. I will discuss our characterization of RNA repair mutants of budding yeast in the context of tRNA splicing and mRNA ligation in the unfolded protein response."
Everyone is welcome and pizza will be served during the seminar. If you would like to meet with the speaker, please email Dr. Chris Miller at

Dr. Diana Tomback quoted in Los Angeles Times

Diana Tomback, Professor in the Department of Integrative Biology, was asked to comment in the Los Angeles Times on a climate change high elevation forest paper. Implicated are Clark's nutcrackers, an important seed disperser for some pines, including limber pine, which have been published on (e.g., Tomback and Kramer 1980, Carsey and Tomback 1994, Tomback et al. 2005). Dr. Tomback's quote can be found in the last two paragraphs of the article.

"Ancient bristlecone pine forests are being overwhelmed by climate change​"



Students receive Department of Integrative Biology Travel Awards

Ryan Parker - M.S. Graduate student advised by Dr. Mike Wunder, received a travel award from the Department of Integrative Biology to attend the 2017 National Wildlife Society (TWS) conference, in Albuquerque, NM. Ryan presented a poster on his research investigating impacts on occupancy of three prairie dog (Cynomys sp.)-associated species: Mountain Plover (Charadrius montanus), Burrowing Owl (Athene cunicularia), and Swift Fox (Vulpes velox). This is the first chapter of Ryan’s thesis work, stemming from trend data collected by the US Forest Service that displays patterns suggesting a trophic interaction.

Paul Le - Ph.D. candidate advised by Dr. Laurel Hartley, received a travel award from the Department of Integrative Biology to attend the 2017 Society of Advancement of Biology Education Research annual conference in Minneapolis, MN. Paul presented a poster describing differences in network metrics in Learning Assistant (LA) and non-LA supported courses and models that predicted student success in introductory biology courses.

Kelsey Foster – Graduate student advised by Dr. Timberley Roane, received a travel award from the Department of Integrative Biology to attend the American Society for Microbiology's international meeting, Microbe, in New Orleans, LA. Kelsey presented a poster at the meeting on her research involving the taxonomic characterization and metabolic profiling of microorganisms within the sediment of the Chattanooga fen. Andrew was additionally awarded a competitive travel grant from the American Society for Microbiology to attend the meeting this June.​
