Special Events

In life, dormancy is a natural  state, which in awakening reminds us of the great resilience  of the things we love so well.  Similarly, TWIB stirs from its slumbers. 

Accolades

Former graduate student Jason Burkhead started this fall in a tenure track faculty position in the Department of Biological Sciences at the University of Alaska Anchorage.

Chris Cohu who succesfully defended his Ph.D. dissertation this summer has been hired as senior biologist at Solix, a biofuels company in Fort Collins.

Welcome

The Garrity lab welcomes two REU students this summer. Crisol "Sol" Morales is from Sacramento City College in California. Maricarmen Perez is from the University of Puerto Rico. Welcome!

The Pilon lab welcomes new post doc Karl Ravet. Karl comes from Montpellier France.

Postdoc Dr. Kyle MacLea joined the Mykles lab in July. He's a graduate of Cornell (A.B.) and Darmouth (Ph.D.). He is most recently from Indianapolis, where he taught at nearby Franklin College.

On the Road

Jennifer Cappa, Colin Quinn, Stormy Dawn Lindblom and Rodolfo Valdez, of the Pilon-Smits lab are traveling to Berkeley, CA mid-May and mid-August to do x-ray absorption spectroscopy studies at the synchrotron of the Lawrence Berkeley Lab.

Pat Bedinger, Paul Covey, and Steve Stack have returned from a 23-day trip (April 16 – May 8)to Peru where they observed, cross pollinated, and collected tissues and fruits from wild tomato species as part of the NSF-funded project titled “GEPR: Using genomic tools to identify interspecific reproductive barriers in the tomato clade”. Other participants included Roger Chetelat (UC Davis), Esther van der Knaap (Ohio State University), Bruce McClure (University of Missouri), Gloria Lopez (Cornell), Reynaldo Nunez (Ohio State University/CIP), and Phillip Kear (University of Missouri/CIP). Aside from awaiting formal permission to return samples to the United States, the trip was successful both scientifically and personally. Early on the group put on a symposium titled “Reproduction in the Solanaceae” at the International Potato Center in Lima (CIP). Pat gave a talk titled “Unilateral Incongruity in the tomato clade,” and Steve gave a talk titled “Cytogenetics of tomato.” However, most of the time was spent on wonderful trips up steep valleys with fast-flowing streams and breath-taking views from narrow gravel roads that often thread along the sides of steep cliffs. The cities were congested with all forms of motor transportation in constant danger of collision. Still there were no serious injuries or illness, and the enthusiastic group got along well together. Google “irbtomato.blogspot.com” for blogs with text and photographs describing the trip.

Assistant professor Rachel Mueller was at NSF June 1-2.

Dr. Greg Florant was performing research with Dr. Loren Buck at the University of Alaska, Anchorage from May 22nd to 29th. Dr. Florant is a mentor in the INBRE program in Alaska which fosters collaborative research between UAA professors and their mentors.

Postdoctoral Fellow Joe Covi traveled to the Oregon Institute of Marine Biology to participate in the initial phase of a two year FIRST (Faculty Institutes for Reforming Science Teaching) IV program. FIRST IV is an NSF funded program intended to improve undergraduate education by providing instructional training and support for postdocs.

The 17th International Chromosome Conference was held June 23-26 in Boone, North Carolina. Several members of the Stack-Anderson lab attended the meeting. In addition, Prof. Steve Stack and Spec. Asst. Prof. Lorrie Anderson were co-organizers of the meeting, Lorrie was program chair, and Steve was the leader for the session on meiosis. Graduate student Joe Qiao presented a poster of his work, and new graduate student Leslie Lohmiller designed the website (www.biology.colostate.edu/icc2009).

The Garrity Lab recently attended the Society for Developmental Biology 68th Annual Meeting in San Fransisco. Yelena Chernyavskaya, Lindsay Parrie and Cory Harrell all presented posters and won travel awards from the society.

Arathi Seshadri gave a talk and presented a poster at the Annual Meeting of the Botanical Society of America in Snowbird, UT, July 25 - 29

Assistant Professor Shane B Kanatous recently gave the keynote address to the summer REU program for the Department of Biochemistry and Molecular Biology at CSU.

Assistant Professor Shane B. Kanatous gave an invited lecture entitled Changes in myoglobin levels during ontogeny that enable long deep dives in Weddell seals at the 2nd International Conference of Respiratory Science in Bad Honnef, Germany.

Prof. Don Mykles continued his research on molting physiology of lobsters and green crabs during the summer at the UC Davis Bodega Marine Lab.

Graduate student Wiebke Tapken attended the Gordon Research Conference on the Cell Biology of metals in RI this August and she presented a poster.

Marinus Pilon gave a lecture at the 5th International Conference on Iron-Sulfur Cluster Biogenesis in Athens GA (Aug 30-Sept 2).

On October 12, Assistant Professor Joe von Fischer gave an invited seminar at the University of Colorado's Institute for Arctic & Alpine Research entitled "Mechanisms controlling terrestrial and aquatic methane release from the Arctic Coastal Tundra at Barrow, Alaska."

Dhruba Naug was a plenary speaker at an European Union action group meeting on honeybee colony loss at Guadalajara, Spain.

Biology Research in the News

Research by Asst. Prof. Joe von Fischer was included in the book Flood Cycle:  Notes from a Changing Planet (2009) by the British artist and writer John Kelly. Kelly observed von Fischer measuring methane emissions from the Arctic tundra, and described the experience: "As I stand looking at the screen, I am aware of the breathing rate of the earth."
