Longjun Wu, a graduate student in the Lambert lab, will be giving a talk entitled, “Lineage-specific genes in Spiralia,” on Friday, March 7.  Longjun comes from the Southeast coast of China, where he received his B.S. in Biology from Xiamen University, studying genome evolution of Amphixous in Dr. Yiquan Wang’s lab.

Emily Landeen, a graduate student of the University of Rochester and member of the Presgraves Lab, is presenting a talk titled, “Speciation and the large X effect.”  Sex chromosomes play an important role in hybrid incompatibilities, a pattern Emily has been investigating in her thesis research.

Cara Brand, a graduate student of the University of Rochester and member of the Presgraves Lab, is presenting a talk titled, “Evolutionary Genetics of the Selfish Segregation Distorter Complex,” on Friday, February 14.  Cara received her B.S. in Biology from the University of Maryland, College Park.  She then spent a year as research technician in Jerry Wilkinson’s lab, working on hybrid male sterility and meiotic drive in stalk-eyed flies.  She is now studying the evolution and genetics of recombination and the selfish Segregation Distorter complex.

Dr. Hernán López-Fernández will be giving a talk titled, “Ancient adaptive radiations and morphological convergence in Neotropical cichlid fishes,” on Friday, February 7.   He is a Curator of Ichthyology in the Department of Natural History at the Royal Ontario Museum in Toronto, Canada.  As a Curator at the ROM, Hernán’s research focuses on the evolutionary biology of South and Central American cichlids. The freshwaters of South and Central America are estimated to harbor well over 6,000 species of fishes, more than any other biogeographic region on Earth. Among this great diversity, cichlid fishes are remarkable for their morphological, ecological and behavioral diversity. Although cichlids are well-known models of adaptive evolution in lakes, little is known about their diversification in rivers. Hernán combines field and laboratory research in systematics, biogeography and evolutionary biology to study the radiations of American cichlids as models of the evolutionary history of Neotropical fishes. Comparative evolutionary studies of cichlids and other groups should provide a powerful tool to understand the origin of the most diverse freshwater fish fauna on the planet.

Dr. Margarita Lopez-Uribe will be giving a talk titled, “Genetic signatures of range expansion of the host-plant specialist squash bee, Peponapis pruinosa,” on Friday, January 31.  She obtained her Bachelor’s degree in Biology at Universidad de los Andes (Colombia) in 2004 and her Masters degree in Genetics and Evolution at Universidade Federal de São Carlos (Brazil) in 2006 under the supervision of Dr. Marco Antonio Del Lama. Currently, she is a PhD student of the Entomology Department at Cornell University researching genetics and population structure of solitary bees.  Her particular interest is in understanding the historical and current role of geography and landscape in shaping gene flow patterns and population structure of bees.  For more information on this research, please visit her website.

Our own Dan Garrigan will be giving Monday seminar on February 2nd at noon in Hutch 473. Dan will be speaking about comparative population genomics in Drosophila.

Adam Johnson, a member of the Lambert lab, will be giving a talk titled, “Posterior patterning in Spiralia: caudal’s role in Ilyanassa” on Friday, January 24. Adam received his Biology BA at the University of Kansas, and worked with Jennifer Gleason and Paulyn Cartwright on mating behavior and Cnidarian sensory evolution, respectively.  Adam is a 3rd year PhD student.

Jeffrey Vedanayagam, a fifth-year graduate student in the Garrigan lab, will be giving a talk entitled, “Genomic conflict and the evolution of small RNA-guided genome defense in Drosophila” on Friday, January 17th.  For more information on Jeffrey’s research, please visit Garrigan website.
