Examining Deformation Evolution in the Wyoming Laramide Foreland

Posted August 4, 2011

Abstract: Amelia Zhi Yi Mentor: Laramide foreland deformation in Wyoming represents a classic tectonic province, yet there are outstanding questions about the kinematic and mechanical processes responsible for the mountain systems seen today. The archetype Laramide orogen, which spans over 1,200km from Central Montana to New Mexico, was formed during the Late Cretaceous to early […]

Holocene Depositional Variability in a Coastal Estuary, Cedar Island, North Carolina

Posted August 4, 2011

Abstract: Anna Woodson Mentor: Donald Barber Mentor: This summer, I am working with Professor Donald Barber on a field and laboratory research project investigating how the rate of sea-level rise has varied over the past 5000 years. We are conducting fieldwork on Cedar Island, located in southern Pamlico Sound, North Carolina. The fieldwork involves collecting […]

Valuation of European Options

Posted August 4, 2011

Abstract: Hoang Ha Mentor: Leslie Cheng This summer, I am doing research on financial mathematics with Professor Leslie Cheng as my advisor. Financial mathematics is a field of applied math that uses mathematical techniques and models to make optimal decisions in the financial market.  Since this subject is new to me, I will first obtain […]

Modeling the ecological niche: Influences of spatial resolution and fractal dimension of the landscape on thermal opportunity

Posted August 4, 2011

Abstract: Congwen Wang Mentor: Micheal W. Sears Species distribution models are often based on data with a spatial resolution that is much larger than the actual environments that individual organisms experience. Further, these models assume that all habitats within a spatial unit are homogeneous. Both of these assumptions are potentially problematic, yet these models are […]

Characterization of Binding Affinity of Gas1 and Gas2 Mutant Proteins

Posted August 2, 2011

Abstract: Chloe Baumann Mentor: Dr. Porello The cell wall’s main component is  a network of β-(1,3)-glucan chains, which are continuously remodeled to meet the needs of the cell in the different stages of cell development.  The family of proteins known as Gas1-5, among other enzymes, are responsible for remodeling the cell wall.  My work this […]

Developing an Educational Display Using Fossil Specimens from the Bryn Mawr College

Posted August 2, 2011

Much of the Bryn Mawr College paleontology collection is currently in storage out of public view. The collection is extensive and diverse and should have a prominent place in the geological displays of the College. The goal of this project is to develop an educational display from some of the best specimens in this collection, […]

Synthesis and Characterization of Pterin-Based Molybdenum Cofactor

Posted July 28, 2011

Abstract: Suyin Lee Mentor: Dr. Sharon Burgmayer Molybdenum is an essential transition element that forms a catalytic center of enzymes such as nitrogenase, nitrate reductases, sulfite oxidase and xanthine oxidoreductases. Some of these enzymes play important roles in carbon, nitrogen and sulfur cycles in the ecosystem while others are essential for proper human neurological development. […]

Summer Research Abstract: Molybdenum Pterin Dithiolene Chemistry

Posted July 26, 2011

Abstract: Yichun Fu Mentor: Dr. Sharon Burgmayer The pterin dithiolene ligand plays an important role in the biochemical functions of the molybdenum cofactor due to its ability to transfer electrons and store charges. The pterin-dithiolene molybdenum complex, has various redox paths that contribute to its multiple functions for the enzyme. Studying the forms and interchange […]

Photolithographic Development of MgB2/MgO/MgB2 Josephson Junctions

Posted July 26, 2011

Abstract: Valerie Galstad Mentor: Xuemei Cheng A strong drive for technological advancement and increased demand for Internet speed and efficiency have made nanoelectronics a very important field of research. With the use of superconductors in nanoelectronics comes more energy efficient electronics capable of faster operational speeds and durability. A Josephson junction is the design of […]

Synthesis and Characterization of Molybdenum Tetrasulfide Complexes and Pterinyl Alkyne

Posted July 26, 2011

Abstract: Suyin Lee Mentor: Dr. Sharon Burgmayer The molybdenum co-factor (Moco) forms the active site of redox reactions in all eukaryotic molybdenum enzymes such as nitrogenase, nitrate reductases, sulfite oxidase and zanthin oxidoreductases. Two different systems, molybdopterin (Figure 1) and iron-molybdenum co-factor have been found to control redox and catalytic functions of molybdenum which serves […]
