Student/Faculty Spotlight

Meet Autumn Quarter 2009 Spotlights! Rachel Mauk, Tim Hawthorne, Nurcan Atalan-Helicke, Scott Reinemann and Michael Ewers

Rachel Mauk

Rachel

Rachel is a second year Master’s student in the Atmospheric Sciences Program working with Jay Hobgood. She specializes in tropical cyclones (TCs), focusing on the North Atlantic basin. Her research interests are TC genesis from both tropical and non-tropical sources, rapid intensification, and numerical modeling. She is also interested in climate literacy and policy. Rachel graduated from Ohio State in June 2008 with B.S. degrees in physics and geography.
Rachel’s thesis examines tropical transition, which occurs when a non-tropical system transforms into a TC. Sometimes called ‘hybrid’ TCs, these storms frequently retain some physical characteristics of their prior non-tropical state after they have been officially classified as tropical by the National Hurricane Center. Hybrid TCs tend to form in the late spring (May and June) and late fall (October through December), though they are possible at nearly any time of year. Hybrid TCs are a significant threat to maritime interests because their unusual structure causes difficulties in accurately forecasting intensity changes. Her project studies the environmental conditions which produced twenty late-fall eastern Atlantic TCs, seventeen of which developed via tropical transition.
Portions of this work were presented at the American Meteorological Society’s (AMS) Annual Meetings in 2008 and 2009, the 28th AMS Hurricane Conference in 2008, and the Denman Undergraduate Research Forum in 2008. This research was supported by an AMS Graduate Fellowship through NOAA’s Climate Program Office and by a Distinguished University Fellowship through the OSU Graduate School.

 

 

Tim Hawthorne

Tim

Tim Hawthorne is a PhD Candidate working on his dissertation research advised by Dr. Mei-Po Kwan as well as a graduate research associate on a multi-disciplinary NSF-funded research project with Dr. Kwan.  Tim’s dissertation, “A Mixed-Method Approach to Healthcare Accessibility in the Near East Side of Columbus, Ohio,” expands conventional GIS measures of healthcare accessibility by focusing on individual healthcare experiences in a predominantly lower-income community. Through his fieldwork with local residents, he learned that many residents in his study area felt neighborhood facilities offered low-quality care. Such comments suggested residents may have an added psychological distance as they attempt to access facilities offering high-quality care. Conventional GIS measures focused on street network distance are inadequate to account for this psychological distance.  Tim used in-depth interviews with residents and GIS to develop new access measures that adjust for psychological distance related to individual quality-of-care experiences.

Tim is also part of a multi-disciplinary research team on one of Dr. Kwan’s National Science Foundation-funded projects: “Dynamics of Space and Time Use.” On the project, Tim works with geographers, sociologists and statisticians to examine neighborhood disadvantage in Los Angeles, California using GIS-based activity space measures, including kernel density surfaces and standard deviational ellipses.

Tim was also the full instructor of the Geography Department’s first service learning course, Geography 580S: Serving the Community with Cartography. In this winter 2009 course, 35 undergraduates learned cartography while working collaboratively with local organizations in the Near East Side of Columbus, Ohio to study accessibility to vital resources and historical points of pride. Over 3000 student-designed maps were distributed to community residents. Students were invited to present their work at a Columbus City Council meeting, the first time OSU undergraduates had been invited for such a purpose.

Tim is currently writing his dissertation and submitting manuscripts about his research and teaching for publication in geography journals.  Tim is expected to graduate in July 2010. 

Besides academic research and teaching, Tim has a keen interest in community outreach and work that is beneficial to an audience beyond academics.  Tim participates in local healthcare discussions as well as community mapping exercises.  Recently, Tim led a community mapping class for local residents at the United Way of Central Ohio.  In his spare time, you can find Tim on the golf course, playing racquetball, or rooting for the Pittsburgh Steelers.

Nurcan Atalan-Helicke

Nurcan

Nurcan Atalan-Helicke is a Ph.D. Candidate with research interests in political ecology, international political economy, agriculture, conservation and development. Her dissertation is titled “European Union Accession and Wheat Diversity in Neoliberal Turkey” and her advisor is Dr. Becky Mansfield. In her dissertation, Nurcan examines how the seed has become the object of intervention for both state policies and international organizations, including the European Union and World Trade Organization, and the farmers’ responses to ongoing socio-political and economic changes in terms of conservation of traditional wheat varieties. Nurcan is from Turkey, and has completed seven-months of fieldwork in rural areas of Turkey, four months in 2007 and three months in 2009, funded by Doctoral Dissertation Research Improvement grant from the NSF. She expects to graduate in June 2010.
Nurcan follows multi-scalar research and complements the analysis of secondary data with findings from ethnographic research. Nurcan presented some of her preliminary findings at the annual meetings of Association of American Geographers, and will present more at the Middle East Studies Association meeting in November 2009. A manuscript about the current legislative changes in Turkey about plant genetic resources is also planned for publication.
Nurcan has been a volunteer for Global Bus Program for OSU outreach activities, and gave several presentations about Turkey, Turkey and the European Union, US Foreign Policy in the Middle East to Ohio communities, both at school age and above. She also follows participatory approaches in her research and had a meeting with 17 stakeholders in July 2009, in one of her research locations, where an action plan for the conservation and marketing of the traditional wheat variety was prepared.

Scott Reinemann

Scott

Scott Reinemann is a second year PhD student specializing in Atmospheric and Climatic Studies. His interests include: biogeography, global environmental change,and paleoclimatology. His research involves utilizing the geochemical and biological characteristics of lake sediment records to reconstruct recent and long-term patterns of climate change in the Great Basin of the western United States. Recently Scott has been involved in developing a quantitative paleo-temperature record for Great Basin National Park spanning the last 7000 years. This project was part of a larger initiative, lead by his adviser David Porinchu, and professors Bryan Mark and Jason Box to study the present and past climatology and hydrology of the Great Basin National Park. The results of Scott's study have been published in Quaternary Research. His paper entitled A multi-proxy paleolimnological reconstruction of Holocene climate conditions in the Great Basin, United States, reveals that late 20th century temperatures in the central Great Basin were exceed only once in the past 7000 years . This warming, which occurred approximately 5200 year ago, corresponds to existing regional records and suggests a regionally synchronous response climate forcing. The quantitative reconstruction of mid-Holocene air temperatures provided by this study can be used to constrain model simulations of past climates and may be used to improve future climate projections for this region. Scott intends to continue work in the western United States for his PhD, which allows him to partake in fieldwork that is also aligned with his more personal interest of the outdoors, including hiking, camping, backpacking, mountaineering, and pretty much anything you can do outdoors in the wilderness.

Michael Ewers

Michael

PhD Candidate Michael Ewers returned to campus this quarter after spending a year in the United Arab Emirates (UAE), funded by a Fulbright-Hays Doctoral Dissertation Abroad Grant.  Michael’s research focuses on the human capital dimensions of international economic development.  He studies how places attract and utilize global human capital and foreign knowledge through migration, trade, and investment as means to generate local development capacity.  His advisor is Dr. Edward J. Malecki.

Michael’s regional specialization is the Middle East, an interest which stems from his four years as an Arabic linguist in the U.S. Marine Corps.  This is reflected in his dissertation, which examines how the UAE and the other Arab Gulf States have used their oil wealth to “import” the labor and human capital necessary to diversify their economies beyond oil. In the Gulf, oil abundance has reduced incentives to create local development capacity, instead promoting a dependence on foreign labor and knowledge.  Michael’s project consists of a four-decade analysis of Gulf industry and labor data, a large-scale survey of foreign and local corporations in the region, and key-informant interviews with companies in Dubai and Abu Dhabi, United Arab Emirates (UAE).

Michael was awarded a 2009/10 Presidential Fellowship from OSU Graduate School and will spend the coming year writing his dissertation.  Michael’s wife, Cheryl, and daughter, Eleanor, accompanied him to the region where he was affiliated with UAE University Geography Department.  He is pictured above with his daughter on the outskirts of the Rub’ al Khali or “Empty Quarter” – one of the largest expanses of desert in the world.
