Was invited to give a talk and sit on a panel on the first day of the recent NSF-EPA-USDA Nanoscale Science and Engineering Grantees Conference in Arlington, Virginia. Good talks on measuring nanomaterials in complex environments (e.g., CNTs in biological organisms, metal and metal oxide particles in environmental media), synthesizing nanomaterials, manufacturing nanomaterials and nano-enabled products, and doing so in as sustainable a fashion as possible.
November 2013: Paper published in ES&T detailing experiments that I helped design, coordinate, and in the case of duckweed, conduct. These experiments tested the toxicity of sulfidized silver nanoparticles (dominant fate in wastewater effluent and biosolids, as well as in anaerobic sediments) to a range of different organisms.
Gave a nano-focused seminar for the UNCW Department of BIology and Marine Biology's seminar. Really enjoyed my visit and meetings with faculty and students, and ate some seminar snacks including delicious TiO2 nanoparticle-containing Oreos. Many thanks to Will White for hosting me, and everyone who made time to meet with me.
Started new round of wetland mesocosm experiments as a part of CEINT funded research. This round we're looking at the impacts of a pulse exposure (like our last experiment) as compared to chronic exposure, and weathered Ag nanoparticles (Ag2S nanoparticles) as compared to fresh nanoparticles (Ag(0) nanoparticles).
Final paper from dissertation research (Colman and Schimel, 2013, SB&B) highlighted by Elsevier as #16 out of the 25 most downloaded articles in Soil Science in 2013.
Was an invited speaker at the International Conference On the Biogeochemistry of Trace Elements (ICOBTE) for their special symposium on the Transport, Fate, Bioavailability and Effects of Manufactured Nanoparticles in the Terrestrial Environment.
Q&A in A to Z Nanotechnology detailing our experiment examining the effects of a realistic exposure of a terrestrial ecosystem to silver nanoparticles in biosolids. Warning, contains giant photos of my head.

Spoke at the Museum of Life + Science's Periodic Table Science Cafe at the Broad Street Cafe. Enjoyed great food, cool refreshing beverages, and an attentive audience brimming with stimulating questions.
