Name: Greg Hermann
Forming cellular compartments: Dr. Hermann’s research group studies the formation of a lysosome-related organelle called the gut granule during embryonic development in the model system C. elegans. Lysosome-related organelles comprise a varied group of cellular compartments that include melanosomes, pigment granules, and lytic granules in humans. Interestingly, they each have unique contents and functions while sharing significant overall similarity to the conventional lysosome. Dr. Hermann’s group is using genomic approaches to identify all of the genes that contribute to the construction of these important cellular compartments .
OREGON HEALTH & SCIENCES UNIVERSITY
Name: Michael V. Danilchik, Ph.D., Professor, Dept. of Integrative Bioscience
The main goal of the laboratory is to understand the cellular basis of embryonic morphogenisis – how cellular activities, movements, and cell-fate decisions are coordinated to carry out the dramatic tissue rearrangements that shape early embryos. We use eggs and embryos of the frog Xenopus laevis as our model system. Xenopus readily lay thousands of eggs at any time of year. The embryos are exceptionally hardy, so they have become one of the most useful model systems for studies involving direct cell manipulations, and microsurgery to investigate key cellular behaviors such as cell locomotion, prostrusive activity, and cell rearrangements. Two current projects in the lab are focused on 1) membrane and cytoskeletal interactions involved in large-scale cellular activities, including cell division and cell rearrangement; and 2) how cells communicate with each other across relatively large distances within the embryo. In conjunction with the mentor, the teacher would develop a project oriented around one of the main research aims of the lab, essentially to test a discrete hybothesis directed at a cellular process important for early vertebrate development. This research will involve the teacher becoming familiar with rearing and handling Xenopus adults for the purpose of harvesting eggs and embryos. Learn how to fertilize and culture embryos to various stages, learn microinjection, microsurgery, and various microscopic techniques, including time lapse micrography, confocal microscopy, immunofluorescence labeling techniques, and how to analyze captured image data with various image-analysis software packages.
Name: William Messer, MD, Ph.D., Assistant Professor, Division of Infectious Diseases and Department of Molecular Microbiology and Immunology
The Messer lab focuses on dengue virus, a pathogen transmitted by mosquitos and endemic throughout the tropical and sub-tropical world. His particular interest is in viral genetics and evolution and how those factors affect viral fitness, viral pathogenicity and the human immune response to dengue virus infection. Dr. Messer’s lab has three areas of active research: 1) the genetic determinants of virus fitness in the mosquito vector Aedes aegypti, 2) strategies to identify the critical targets of neutralizing antibodies following dengue infection and, 3) using biochemically derived RNA structural models and dENV reverse genetics to identify RNA secondary structures critical to dengue virus viability. As a former middle school science teacher, Dr. Messer has a particular interest in advancing science education at the secondary school level and have several years experience as an outreach educator working with middle school students. The teacher/intern would be given the opportunity to be come competent in the fundamental tools of virology, including tissue culture, molecular virology, including PCR, sequence analysis, nucleotide mutagenesis and cloning methods. Together, the teacher and Dr. Messer would develop a self-standing project within the framework of the current work to develop and test a specific hypothesis regarding the role of dengue virus genetics in one of several spheres of virology in which they work. The teacher intern will take the lead in the design, execution and evaluation of the results of his/her experiments The teacher/intern would also have the opportunity to function as a full member of the lab, including presenting at lab meeting, journal clubs, and, if opportunity arises, regional or national meetings.
OREGON NATIONAL PRIMATE RESEARCH CENTER
The Oregon National Primate Research Center (ONPRC) is an institute of Oregon Health & Science University, located on OHSU’s West Campus, in Beaverton, OR. One of 8 National Primate Research Centers located throughout the country, and supported by the National Institutes of Health (NIH), ONPRC serves as a national resource to biomedical scientists who require nonhuman primate models for their research. To learn more about the research programs conducted at ONPRC, visit http://www.ohsu.edu/onprc .
Research that takes place at ONPRC/OHSU is undertaken to improve understanding of human health and disease. Animal models are essential in this pursuit, and applicants need to be aware that in certain cases invasive animal procedures are necessary. Ethical issues associated with research in humans and other animals can evoke strong controversy, yet animal research is presently our only means of answering certain critical questions that we hope will lead to improved therapies and/or cures for disease. Federal law mandates adherence to regulations that ensure our research procedures are both humane and justified in terms of their contribution to knowledge and medical practice. Persons who apply for apprenticeship positions at ONPRC should support the ethical conduct of animal research that is carried out in compliance with federal laws and regulations.
The following ONPRC scientists are interested in mentoring a high school teacher. If you are interested in partnering with one or more of these scientists, please contact Diana Gordon (503-690-5201 or email@example.com).
Name: Kristine Coleman, PhD, Assistant Scientist, Division of Animal Resources
As Head of the Behavioral Sciences Unit at the ONPRC, Dr. Coleman’s role is to oversee the
psychological well-being of the non-human primates who live at the Center. In addition to making daily
observations of the monkeys for husbandry and scientific purposes, she and her staff are engaged in a
number of behavioral research studies. Such studies have included the influence of behavioral
inhibition (shyness vs. boldness) on the trainability of animals, mate selection behavior and dominance
in group-housed animals, and the effects of density on group dynamics.
The teacher/intern will learn behavioral methodology, including the design and use of ethograms, how to use software specifically designed for behavioral observation, and statistical methods. S/he will also learn about species specific monkey behavior and will have the opportunity to use operant conditioning (positive reinforcement) to train monkeys to cooperate with husbandry and research procedures.
Name: Larry Sherman, PhD, Senior Scientist, Division of Neuroscience
Dr. Sherman’s lab is focused on understanding ways to promote the repair of the damaged nervous system in a number of conditions including multiple sclerosis, Alzheimer’s Disease, and following chemical insults including cancer chemotherapy drugs and heavy drinking. The Sherman lab discovered that a sugar molecule, called hyaluronan (HA), regulates how neural stem cells and progenitor cells differentiate and proliferate, and that abnormal synthesis and degradation of HA prevents nervous system repair. A major goal of the lab is to develop novel strategies to promote nervous system repair by altering the catabolism of HA. They are currently looking at gene therapy, stem cell-based therapies, and drug discovery approaches to achieve this goal. The successful candidate will be expected to actively participate in designing, performing and interpreting data from these experiments. Candidates will be included on any publications arising from their time in the laboratory.
The teacher/intern will learn a variety of biochemical, molecular and cell biology approaches to address a critical problem in the field of neuroscience research. These techniques will include primary cell culture, RT-PCR, immunocytochemistry, ELISA, and laser confocal microscopy.

Through recent genomic studies conducted in our laboratory we are beginning to understand how various cellular activities lead to the rupture of the ovulatory follicle and the release of a fertilizable oocyte. Areas of focus include defining the significant cellular reorganization and extracellular matrix remodeling that occur prior to and following ovulation, as well as the role bioactive
lipid metabolites such as prostaglandins play in coordinating events necessary for follicle rupture. The teacher will participate in studies that ultimately contribute to the development of novel approaches to control fertility, including the identification of processes that promote fertility in women seeking to have children or for the development of non-hormonal female contraceptives. The teacher/intern will perform cellular and molecular studies of the primate follicle and/or corpus luteum. The teacher/intern will have the opportunity to participate in studies designed to quantitate the level of specific mRNAs using state of the art real-time or microfluidic PCR, the expression of proteins by Western blot, and cellular localization of protein expression using immunohistochemistry.
Name: Henryk Urbanski, PhD, Senior Scientist, Division of Neuroscience

This basic research is expected to provide new insights into the causes of perturbed circadian rhythms and centrally-originating reproductive disorders; it should also help us to elucidate the causes of seasonal affective disorder (SAD). Overall, a better understanding of the underlying neuroendocrine circuits will help with the future development of effective therapies.
The teacher/intern would gain proficiency in the use of molecular and cellular approaches in neuroscience research. He or she would become familiar with the use of general laboratory equipment and also become experienced with specialized techniques such as immunohistochemistry and computer-assisted image analysis.

Department of Biology
Name: Anne W. Thompson, Research Assistant Professor
Phytoplankton in the oceans are responsible for half of the oxygen in our atmosphere and have been important in shaping the atmosphere of Earth as we know it today. These abundant and ubiquitous populations of microorganisms are also the foundation of marine food webs and play important roles in the global carbon cycle. In our lab, we study the ecology of the very abundant cyanobacterium called Prochlorococcus, which is the most abundant photosynthetic cell on the planet Earth. Prochlorococcus is very diverse at the genetic level, but the consequences of this diversity to their role in global processes is poorly understood. In my lab, we study natural populations of Prochlorococcus in the open ocean and laboratory cultures to discover the relationship between genetic diversity and ecosystem function. Projects in my lab could involve techniques such as field sampling in the open ocean, flow cytometry, molecular biology, microbiology, and bioinformatic analysis.

Name: Cat de Rivera, Associate Professor, Department of Environmental Science & Management
We are investigating the effects of sea level rise and dike removal on salt marsh habitat and communities. We are interested in whether the regeneration and uphill spread of this important habitat can keep pace with sea level rise, whether the disturbance of changed inundation favors invasive species, and whether restoration via dike removal should be accompanied by plantings or other assisted colonization. Partner teachers can join a collaborative team investigating how soils (Dr. Martin Lafrenz, PSU Geography), plants (Dr. Sarah Eppley, PSU Biology), and animals that live in the mud (this project) change at each elevation when salt water newly inundates mudflat and marsh areas. The project will entail some field work on the Oregon coast for data collection and experiments and also microscope work back in Portland sorting out and identifying the polychaetes, clams, crustaceans, and other animals we find.

Electron microscopes can be used to image specimens and materials with unprecedented detail. An important tool for research in a variety of scientific and engineering fields, the electron microscope can also be a useful tool for education purposes. For example, the ease with which these instruments can be used to image a variety of materials and objects, and their ability to rapidly zoom in smoothly from millimeter to nanometer feature sizes without refocusing, provides students with a visceral understanding of lengthscale, as well as detailed knowledge about the composition and structure of specimens. Furthermore, the operating principles of the electron microscope itself can also be used to educate. Concepts central to an electron microscope – electromagnetism, electrons, gas pressure, optics, atomic composition of matter – are accessible to high school science students. The McMorran Lab uses these instruments for fundamental experiments in electron optics and quantum physics. This work involves development of cutting edge nanoscale manufacturing techniques and application of advanced physics concepts, yet nevertheless much of this is accessible to new students of physics. This lab is looking to partner with K-12 educators who are interested in contributing to this research, and who would like to help develop curriculum featuring these tools.

Name: Eric I Corwin, Assistant Professor
Self-assembly describes the formation of ordered structures or patterns via the autonomous organization of components without human intervention. Self-assembly processes are largely governed by the structure and nature of the components involved and random forces typically (but not always) related to temperature. Understanding these processes is key to designing components for application that organize themselves into desired patterns that perform a desired function. We have designed a macroscopic analog for microscopic self-assembly using the “Cheerios” effect (surface tension induced interactions) as our driving force. Small Teflon discs will spontaneously organize into two-dimensional crystals when placed on a water surface. By exciting random vibrations on the water surface we are able to mimic thermal forces acting on the Teflon disks. This summer we hope to use this system to explore two-dimensional melting and crystallization/glass formation. We will record data with a video system and analyze collective particle motions and positional order using computerized tracking algorithms.

My laboratory investigates the genes and mechanisms underlying the biogenesis of the chloroplast, the subcellular organelle in plants that carries out the process of photosynthesis. Projects in my laboratory use “genetic” and “biochemical” approaches. We take advantage of mutant plants with non-functional chloroplasts to identify relevant genes, and we investigate mechanisms by which such genes act through detailed biochemical studies of their gene products. Our projects focus primarily on understanding how genes in the nuclear genome promote the proper expression of the small genome in the chloroplast, which was retained from the chloroplast’s bacterial ancestor.
