Why Did Americans Stop Eating Locally?

Why Did Americans Stop Eating Locally?

September 11, 2014 7:00 PM  – 9:00 PM
Sills Hall, Smith Auditorium

In his talk Matthew Booker will explore why urban Americans radically changed their diets in the twentieth century. Tracing the American diet from local oysters to long distance burgers, he will suggest ways we can learn from this history as we rethink today's and tomorrow's food.

Matthew Booker is an associate professor of History at North Carolina State University, and a specialist in Environmental History and Western North American History.

Stem Cell Tumors: Getting Their Fix on the Fly

Stem Cell Tumors: Getting Their Fix on the Fly

September 18, 2014 4:00 PM  – 5:00 PM
Druckenmiller Hall, Room 016

Michelle Markstein, Assistant Professor, Biology Department, University of Massachusetts, Amherst

Research Interests: Stem cells and cancer

The Markstein lab seeks to understand the stem cell properties of cancer cells with the goal of developing new cancer therapeutics. We focus on cell-cell interactions within the stem cell microenvironment and on the plasticity of stem cell genome architecture. Our approach is in vivo, using the fruit fly Drosophila melanogaster to screen for anti-cancer drugs and drug targets.

Developing a broader perspective for marine communities in an area of climate change: insights from the Galapagos Islands

Developing a broader perspective for marine communities in an area of climate change: insights from the Galapagos Islands

September 25, 2014 4:00 PM  – 5:00 PM
Druckenmiller Hall, Room 020

Jon D. Witman, Professor, Biology Department, Brown University

Research Interest:
My research is directed toward understanding the dynamics of populations and communities living in marine hard substrate habitats. Our lab is conducting research focused around three themes: 1) physical forcing of marine benthic ecosystems, 2) studies on the origin vs. the maintenance of pattern, and 3) marine biodiversity. How community structuring processes vary with scale is a consideration that pervades all aspects of our research.

Steve Dudgeon, Professor, Marine Biology Department, California State University, Northridge

Research Interest:
My research interests lie in two areas. One is the different levels of integration exhibited among individual organisms aggregated in a group, clone or colony and how this variation impacts both, their population ecology, and the evolution of their life histories. The second is the scale- and context-dependence of ecological processes in community development. I study both benthic marine invertebrates and seaweeds for three reasons: (1) both taxa are easily manipulated in field and laboratory experiments; (2) interactions between these taxa are often central features of community organization; (3) a great diversity of unitary and clonal lifestyles (often in a single lineage) coexist in one ecosystem.

Ben Ewen-Campen, Postdoctoral Candidate, Extavour Lab, Harvard University

Research in the Extavour lab is aimed at understanding the causes and consequences of evolutionary change in developmental processes. We are especially interested in those genes and developmental processes that direct cell fate specification in early embryogenesis. Our experimental work is primarily focused on the evolution and development of germ cells and reproductive systems in animals. Multicellularity evolved many times in eukaryotes, and in each instance, when cells of the multicellular aggregate first begin to adopt distinct fates, the first division of labor to arise is one that separates a reproductive lineage (the germ line) from a sterile lineage (the soma). A dedicated germ line is thus a profound novelty and critical feature of multicellular life. In sexually reproducing organisms, only the germ cells can contribute their genome to the next generation. Consequently, germ line specification and gonad function can have significant impacts on reproductive success and fitness.

New regulatory functions for ancient RNA-modifying enzymes

New regulatory functions for ancient RNA-modifying enzymes

November 13, 2014 4:00 PM  – 5:00 PM
Druckenmiller Hall, Room 020

Wendy Gilbert, Professor of Biology, MIT
Research:
The proteins of a cell are the primary determinants of cellular form and function. Regulation of the proteome is therefore the ultimate goal of signaling pathways that connect cell physiology to internal and external environmental cues. We study the molecular mechanisms and physiological functions of translational control of gene expression using genome-wide translation state profiling, molecular genetics, and biochemistry.

Robin Hopkins, Professor of Organismic and Evolutionary Biology

Research Interest:
A major goal of evolutionary biology is to understand the process of speciation. Of particular interest is evaluating the role of natural selection in causing diverging populations to become species. Addressing these goals entails investigating fundamental questions of evolutionary biology such as: What is the genetic basis of adaptations? What is the role of migration and genetic drift during the evolution of traits? What is the strength of selection acting on an adaptive allele? And what is the mechanism underlying selection? My work incorporates molecular biology, population genetic analyses, and field-based selection experiments to address these questions. My research examines speciation in plants, predominantly focused on reinforcement, the process in which reduced hybrid fitness generates selection for the evolution of reproductive isolation between emerging species. I use an interdisciplinary approach that incorporates functional molecular biology experiments, population genetic analyses

Having it both ways: The developmental genetics of dimorphisms in true bugs

December 4, 2014 4:00 PM  – 5:00 PM
Druckenmiller Hall, Room 020

David R. Angelini, Assistant Professor of Biology, Colby College

Research focus:
Our lab is broadly interested in the developmental and molecular genetic aspects of morphological evolution, part of the growing field of evo-devo. Using developmental genetics, molecular biology, morphometric and phylogenetic methods, we seek to understand the interactions and functions of genes and their networks in the evolutionary histories that have led to animal diversity. Insects and other arthropods have been our study organisms.
