I am interested in ecological and evolutionary questions in aquatic systems, particularly related to global species patterns, population genetics, parasitology, historical ecology, conservation biology, and the unique and integrative insight that can be gained from studying biological invasions. I am also interested in biogeographic and phylogeographic patterns of hosts and parasites, host-parasite interactions, and the influence of parasites in native and non-native communities.

**A high school intern, Isabela Kernin, whom I mentored for the past two summers (2013-2014) just submitted her manuscript yesterday (11/10/14) for the Intel Science Talent Search competition (http://www.intel.com/content/www/us/en/education/competitions/science-talent-search.html)! Congratulations to Isabela!

**A paper I am a co-author on was recently published in the Royal Society Open Science journal. The paper concerns the dynamic nature of the green crab invasion along the east coast of North America and the admixture of the crab's two major invasion fronts. The title is: "Are genes faster than crabs? Intraspecific admixture facilitates expansion of mitochondrial genomes beyond an established population range limit" and is authored by J. A. Darling, Y-H. E. Tsai, A.M.H. Blakeslee & J. Roman. See the paper here: http://rsos.royalsocietypublishing.org/content/royopensci/1/2/140202.full.pdf

**Our summer LIU-Post interns in the Biology department just gave a conference style presentation on their research this summer on Friday, August 1st. As the Internship coordinator, I gave opening remarks on our internship program, which is in its third year. The students then each presented for about 20 minutes and had 10 minutes for questions. The conference was well attended and the students received a lot of good feedback and experience.

**From June to July 2014, I spent a month in Scotland for a research exchange grant [Postdoctoral and Early Career Researcher Exchanges (PECRE) for Marine Alliance for Science & Technology in Scotland (MASTS)] with a colleague, Anna Kintner, at the Scottish Oceans Institute at the University of St. Andrews. Our project is entitled: "Phylogeography, population links and gene flow between Obelia geniculata hydrozoans in northern Scotland." We collected Obelia geniculata samples from multiple populations throughout northwest Scotland, including the Highlands, Orkney, and Shetland. I also gave an invited presentation to the MASTS network at the University of St. Andrews (http://www.masts.ac.uk/masts-research/webinars/). Below are gratuitous pictures of Puffins and lambs on Shetland and pictures of our work in Scotland (and the beautiful land and seascapes).


**In January 2014, Jaclyn Onufrey of Wantagh High School was named an Intel semifinalist for the National Intel Science Talent Search for high school students (https://student.societyforscience.org/intel-sts-2014-semifinalists) for the paper she wrote based on the work she did in my lab summer 2013, in which I served as her faculty mentor. Jaclyn is the first student in her high school to ever be named a semifinalist for the Intel competition. The following are some other links related to Jaclyn as an Intel semifinalist: Newsday article; Wantagh High School.

**In May 2012, a story on ongoing work with the baitworm vector was published at SERC's Shorelines publication. Read more here: http://sercblog.si.edu/?p=2096#more-2096


**A publication based on my research was featured on the Smithsonian Environmental Research Center website in February 2012: http://www.serc.si.edu/labs/marine_invasions/feature_story/February_2012.aspxFeature Story February 2012: "Can the invasion process free snails of their castrating parasites?"

**A publication I co-authored was featured on "Science Daily.com" in September 2011: "Location Matters: For Invasive Aquatic Species, It's Better to Start Upstream"

ScienceDaily (Sep. 26, 2011) — Researchers have found that a species invasion that starts at the upstream edge of its range may have a major advantage over downstream competitors, at least in environments with a strong prevailing direction of water or wind currents.
