Melina Acevedo, 2016 Chemistry This summer I conducted research in the Koel lab of the Princeton CBE department. The purpose of my research was to synthesize and characterize copper nanowires for alkaline water splitting. I used scanning electron microscopy to characterize my nanowires, and cyclic voltammetry and polarization curves to asses their activity for the hydrogen evolution reaction. In addition to gaining familiarity with microscopy and electrochemistry techniques, I also gained perspective as to what life is like as a materials science/chemical engineering graduate student. Overall, this internship allowed me to... read more

Emily Ho, 2018 Undeclared I worked as a research intern for Dr. Sam Cohen at the Princeton Plasma Physics Laboratory (PPPL), which is dedicated to achieving fusion as an economical and clean alternative energy source. Dr. Cohen is focused on a type of reactor called the Princeton Field-Reversed Configuration (PFRC-2) because he believes that small reactors are the safest, most sensible means to that end. Under his tutelage, I studied and examined the various causes of oscillations in the plasma. Understanding the behavior of the oscillations of ions and electrons and interactions between those oscillations is key to... read more

Sally Jiao, 2018 Chemical and Biological Engineering In organic semiconductors, charge is transported from molecule to molecule along conjugated backbones. Understanding how various factors affect the arrangement of these molecules (i.e. how they crystallize) can help us build more efficient organic electronic devices. To that end, I researched the thin-film crystallization of TES-ADT (triethylsilylethynyl anthradithiophene), an organic semiconductor. TES-ADT films are disordered upon spincoating, but crystallize upon exposure to 1,2-dichloroethane vapor. My project focused on probing the relationship between the thickness of a TES-ADT film and... read more

Bizuwork Melesse, 2016 Chemistry My summer internship in Professor Craig Arnold’s lab consisted of working with beyond-lithium battery solutions, specifically, magnesium ion batteries. A promising alternative to lithium ion batteries, magnesium ion batteries provide a safer yet cost-effective means of energy storage. However, the full potential of such battery systems is yet to be realized because of the lack of a combination of robust electrolyte and cathode materials. To that end, my main goal this summer was to design, synthesize, and characterize metal oxide-based cathode materials. In the process of designing the... read more

Jacob Pearcy, 2018 Physics Over the summer, I assisted in performing diagnostics and expanding theoretical explanations regarding X-ray emission from the Princeton Field-Reversed Configuration 2 (PFRC-2) device. Through a combination of data gathering, data analysis, simulation, and theoretical calculations I helped the research team gain a fuller understanding of the characteristics and some possible causes of unexpectedly high X-ray emission. As a result of the internship, I feel much more prepared to conduct scientific research in the future, and my experience has solidified my desire to pursue physics as my major.

Carol Chiu, 2017 Chemical and Biological Engineering For summer 2015, I researched in the Morel lab on the benefits of the alternative nitrogenases over the Mo nitrogenase in a purple nonsulfur bacterium called Rhodopseudomonas palustris. Nitrogenase is the enzyme used for nitrogen fixation. R. palustris is special in that it can express three types of nitrogenase, Mo, V, and Fe. I discovered that the alternative nitrogenases grow better than the Mo nitrogenase in more reduced environments. The theory is that the alternative nitrogenases are better at getting rid of excess electrons during nitrogen fixation.

However, such deployments have high maintenance and ownership costs, for which low-cost UAVs would be a feasible solution. In Professor Wysocki's laboratory a new prototype of laserspectroscopic sensors have been developed in collaboration with... read more

The goal of my Smith-Newton Research Project this summer was to purify tree distillates of organic contaminants using algae and chitosan hydrogel beads. The current standard of using activated charcoal as a purifying agent is not sufficient. My solution to this, a new bio-sorption technique using algae and chitosan to purify these tree distillates of organic contaminants, looks to be promising in allowing for more accurate study of water isotopes, and allows for a deeper study of water transportation amongst competing trees. This summer, I increased my familiarity with cryogenic vacuum... read more

Christine Chen, 2013 Geosciences The Wonoka formation, a deposit of Ediacaran-aged (635 - 542 million years ago) carbonate rocks found in South Australia, holds a record of carbon isotopic signatures of ancient oceans. These isotopic signatures suggest a major disturbance to the Ediacaran global carbon cycle—one that dwarfs humanity’s carbon dioxide (CO₂) emissions. This perturbation has been casually linked to the broadly synchronous radiation of macroscopic ­multicellular ­organisms during the Ediacaran.  As a geology field assistant to Jonathan Husson, a ­graduate student in the Department of Geosciences, I helped... read more

By utilizing a certain type of magnetic field, fusion reactors can be built on a smaller, easier-to-construct scale. This sort of field would allow for a simpler reactor, along with “closed” field lines that provide for superior containment.

However, the gypsy moth periodically defoliates the Pine Barrens, with a heavy preference for oak over pine trees. This causes changes in forest composition and growth, as well as alterations in the... read more

Dmitri Garbuzov, 2010 Computer Science My project consisted of two distinct but related parts. In order to familiarize myself with the flexible modeling system and the various development tools used at GFDL I first took an existing module that implemented a new emission scheme for mineral dust in an older version of the coupled model and moved it into a standalone version of LM3 to facilitate testing and tuning. This served as an introduction to developing and building models rather than just using them for experiments.

While magnetic fluxes through diagnostic Mirnov coils and flux loops on the LTX machine yield data which may be used to constrain plasma parameters during reconstruction, the measured signals are often highly sensitive to magnetically induced eddy currents in the conducting shell, and digital integrator circuits introduce error into the gain factors for the sensors.  Over the course of 10 weeks, I created a meshed representation of the conducting metal shell around the LTX machine for... read more

Lavanya Jose, 2012 Computer Science This summer, I worked in Professor Jennifer Rexford’s group in the Department of Computer Science on tools for monitoring traffic on computer networks. To this end, I developed a power-efficient algorithm for identifying "hierarchical heavy hitters" in real-time on a network using commercial hardware and commodity Ternary Content Addressable Memories (TCAMs). I then implemented the algorithm on OpenFlow, an open standard that allows researchers to run experimental protocols in production networks.

By blending two compounds with similar structures but different energy levels, I was able to create a range of blend ­morphologies. These showed a correlation between the blend composition and device mobility, that I then continued to investigate using Atomic Force Microscopy and Differential Scanning Calorimetry. In the end, I found that the device performance improved with more ­diffuse grain boundaries, and reached a maximum at an eutectic point. Many thanks... read more

Elizabeth Paul, 2015 Astrophysical Sciences Nuclear fusion has long been regarded as a potential alternative to fossil fuels and a technology that could ensure a safe energy future. An advanced fuel fusion reactor, the Field Reversed Configuration, is especially promising as it is smaller and cleaner than the more widely studied tokamak. My project explored the transfer of energy between the very energetic particles produced in the fusion reaction and the plasma in the scrape-off layer, the relatively thin outer layer of the reactor. By the end of the summer I began to understand how to optimize the simulation of this process, and... read more

This sensor will ultimately serve as a field-deployed system in Toolik Lake, Alaska where permafrost thaw is releasing large amounts of methane. Methane, a greenhouse gas that has 25 times the global warming potential of CO2 over a 100-year period, is being released from the permafrost and is contributing to global temperature increase, creating a positive feedback cycle that results in further melting of permafrost. After doing preliminary field... read more

Kevin Steinberger, 2012 Mechanical and Aerospace Engineering The goal of my internship this summer was to conduct research on biochar. The ­production of biochar, defined as a form of charcoal created from biomass and used for agricultural purposes, has recently been praised as a carbon negative ­technology, and represents a way to remove carbon dioxide from the atmosphere while ­simultaneously improving soil quality in some cases. Biochar has the potential to ­significantly ­reduce greenhouse gas emissions through the long-term storage of carbon in soils. I reviewed the current literature on biochar and started to create an Excel ­model to explore all... read more

Andrew Stella, 2013 Chemical Engineering It is commonly cited by solar power advocates that the rate of energy incident on Earth's surface from the sun outpaces our global consumption by several orders of magnitude. So why then aren't solar panels ubiquitous? One reason is cost. The subject of my internship with the Ceramic Materials Lab, the dye-sensitized solar cell, is a relatively young and promising solution. From an energy challenge viewpoint, the goal of my research was to help both decrease the cost and increase the lifetime of these devices through component engineering.

Justin Mehl, 2017 Chemical and Biological Engineering This summer, I worked with the Myneni Research group on using iron oxides to adsorb arsenic from contaminated water. In countries and regions such as Bangladesh and Eastern Africa, arsenic contamination is a serious problem with no cost-effective solution. Studies have shown that iron oxide crystals can be used to adsorb arsenic from contaminated water. These filters have been used, but the commonly used substrates on which the crystals are grown, activated carbon or silica, are not widely available in areas afflicted by arsenic contamination. The goals for the summer were to study how iron... read more

Joshua Murray, 2018 Geosciences The Columbia River Basalt Group is a collection of lava flows in the Pacific Northwest that formed mostly between 17 and 14 million years ago. The basalt flows themselves can be over a kilometer thick: smaller than the Deccan and Siberian Traps, which are often thought of as causes of mass-extinction events, but still significant enough to have influenced climate. By collecting samples of sediment that accumulate during hiatuses of volcanic activity throughout the stratigraphy in Washington, Oregon and Idaho, then separating the mineral zircon from these sediments, our group hopes to date... read more

Every six months, Mpala performs a rigorous survey of the wildlife population using distance sampling; I collected data for their June and July 2013 samplings. The Center could then compare the data I helped collect with data from a more easily executed survey the rangers conducted to ascertain whether the ranger-based method was reliable and efficient. I spent early mornings and late afternoons with another Princeton student and some members of the... read more

Haley Lane, 2016 Civil and Environmental Engineering The area surrounding Mt. Kenya is unique due to the sharp precipitation gradient the peak generates. Because of this precipitation disparity intrinsic to the Laikipia Plateau, the region is home to both large scale industrial farming and communities afflicted by serious drought. The overarching goal of this project was to determine water availability in both upstream and downstream communities and to assess the relative effectiveness of the governmental structures that systematize local water usage. In addition to collaborating with local government officials, my work centered on profiling... read more

Kathleen LaRow, 2012 Ecology and Evolutionary Biology Working for Frontier, a non profit conservation and development NGO, as a research assistant was an amazing experience. Over the summer, I helped to collect data that will be used to examine the effectiveness of the Marine Protected Area. The hope is that placing this area under protection has promoted an increase in biodiversity and abundance of marine populations. To investigate this hypothesis, I conducted underwater marine surveys of the quantity and types of reef fish, coral, and invertebrates on twenty-five meter transects. Along with diving to collect data on marine life, I helped... read more

I spent the summer in Kenya as an intern with Grevy’s Zebra Trust, a non-profit Kenya-based organization dedicated to conserving the endangered species of Grevy’s zebra. My time in Kenya was divided between working in an office at Mpala Research Center and field work in the Samburu Heartland, a remote region in north-central Kenya. In Samburu, I helped install a new water monitoring project, through which we made water more accessible to wildlife across Samburu during its dry season, when water is a limited resource for much of the wildlife. I also helped spread awareness to local community... read more

Delphine Slotten, 2015 Woodrow Wilson School My internship work was part of a greater study to determine how two different livestock grazing regimes – traditional and “holistic” – affect the health of livestock; the quantity, quality, and diversity of vegetation; and the presence of wildlife in the West Gate Community Conservancy (WGCC) of Samburu County, Kenya. Some pastoralists in West Gate have adopted “holistic management” practices – namely rotational grazing. However, few quantitative assessments have been conducted to determine the impact of these practices on cattle health, vegetation, and wildlife. Thus, with the principle goal... read more

Katherine Smith, 2015 Ecology and Evolutionary Biology My project brought together ecology and chemistry, as I worked for both an ecology professor and an engineering professor with an interest in ecohydrology. I spent my time this summer focusing on water; specifically, a river’s interactions with other parts of the ecosystem, including both flora and fauna. I examined the role of grazing on water stress in plants near rivers, as well as the differences in water source in plants located on different bank slopes. On a given day, I would collect soil, grass, and water samples and bring them back to the lab, where I would process the samples to... read more

Sarah Stroud, 2012 Ecology and Evolutionary Biology Under the guidance of Daniel Rubenstein, Professor of Ecology and Evolutionary Biology, I spent the majority of my internship in Kenya in Wamba, at an Earthwatch research center. During that time I conducted research on the Grevy Zebra which is an endangered species. Fewer than 2500 remain. As part of this research I walked line transects and conducted total counts from a vehicle on the Grevy's Zebra population in the area (animals considered competitors for food were also counted). I was also in charge of entering project data and for maintaining camp equipment.

In Professor Claire Gmachl’s laboratory, experiments explored the possibility of using powerful and tunable lasers known as Quantum Cascade Lasers, or QCLs, for such sensing purposes. I spent the summer programming in a language called Labview, in order to control laboratory equipment via computer. My program controlled both a QCL and a bi-axial rotation device (BARD), capable of rotating two... read more

Kathleen Brite, 2013 Politics The overall goal of my project with the Desmond Tutu HIV Foundation was to produce a history of its ground-breaking mobile testing unit, the Tutu Tester. This history was to be published and used in reviving HIV/AIDS awareness and reducing stigma, re-conceptualizing HIV as preventable, manageable, and part of comprehensive wellness. The history would also assess what has been accomplished in the field of HIV in South Africa, what is being done currently, and what is needed going forward. In addition to working daily in the townships doing biometric registration on the Tester, I conducted... read more

Abdallah Bukari, 2010 Chemical Engineering The purpose of this internship was to research with the Prudíhomme group a novel drug delivery system for the administration of tuberculosis therapeutics. This delivery system, which can be incorporated into current therapeutic regimens, will quickly and efficiently kill off a large percentage of the infection in a short time, reducing the duration of therapy and frequency of dosing needed. The improved performance of this regimen is derived from the design of the NP system.  Usually, there is little control over the release and biodistribution of combination therapy drugs in circulation... read more

Rebecca Butler, 2010 Ecology and Evolutionary Biology The spread of antibiotic resistant bacteria has led to bacterial infections that are more difficult and more costly to treat. Understanding the spread of antibiotic resistant bacteria is a necessary precursor to implementing effective measures to control the transmission.  Much of my time at RFF was spent updating a model of steptococcal transmission in day care centers that made use of an extensive database containing data from an intervention project in Sweden.  The model, coded in R, showed the effects of various policies in containing penicillin-resistant pneumococci.  I... read more

Priscella Chan, 2014 Ecology and Evolutionary Biology This summer I interned with the Oxford Clinical Research Unit, and worked on mapping the burden of typhoid fever, which is endemic in Southeast Asia. Not only do some patients die from complications of the disease, but since typhoid is treated with antimicrobials, patients must also face the challenges of increased drug resistance. This summer, I conducted literature research on the case fatality rates and drug resistance patterns of typhoid disease in a variety of countries in Southeast Asia. Since the majority of articles and trials detailing the incidence rates and antimicrobial resistance... read more

Liz Chen, 2010 Anthropology This summer I worked for the Pan American Health Organization in El Paso, TX. While I was on the US-Mexico Border I worked specifically on projects related to chronic diseases such as childhood obesity and diabetes. I conducted large systematic reviews of obesity legislation in both the US and Mexico and compiled studies that use mass media campaigns to combat the obesity epidemic. In addition to my internship I spent my time outside the office learning from promotoras (community health workers) specifically trained in HIV/AIDS. These promotoras had a lot to say and I learned a lot about... read more

Julie Chong, 2017 Civil and Environmental Engineering This summer I researched the environmental impacts of fireproofing material in building construction. To maintain the integrity of a building and the safety of its occupants, steel beams and columns require a fireproofing barrier, because steel becomes malleable when subjected to the heat of a fire. ‘Prescriptive’ structural design calls for a standardized amount of fireproofing material for every beam and column. This approach, however, can lead to blind adherence to building codes and over-application. Unnecessary energy is used to produce, transport and install the surplus. Hence, a new... read more

Jacqueline Chu, 2015 Undeclared My internship at the Oxford University Clinical Research Unit focused on analyzing and summarizing data gathered on antibiotic use and antibiotic knowledge by aquaculture farmers in Vietnam. The data I analyzed was obtained from a direct survey of farmers in Vietnam and from biological analysis of aquaculture products collected from local Vietnamese markets. This information is a vital step in creating strategies to tackle antibiotic resistance in pathogenic bacteria. Since aquaculture products account for a large portion of the Vietnamese diet, aquaculture's use of antibiotics can have a... read more

Fatu S. Conteh, 2010 Chemistry It's a fact: malaria kills over a million people a year and stands in the way of economic development for many countries where the disease is endemic. Past efforts to eradicate this deadly disease with drug treatments like quinine, chloriquine, and other antimalarials have proven futile as the malaria parasite (Plasmodium Falciparum) has developed resistance to these drugs. However, artemisinin, with no known stable resistance, has been ganarring momentous support from both the non-profit and for-profit sectors as the first line drug treatment for uncomplicated and multi-drug resistant P.... read more

Courtney Crumpler, 2013 Undeclared I carried out an independent research project in Brazil with ABIA’s Companhia da Saúde, a group of adolescent performers who use street theater, song and dance, colorful costumes and even some circus techniques to present messages of AIDS prevention and solidarity in a fun and creative way. I spent five weeks observing rehearsals, taking photographs, and conducting interviews with the members of the company and its directors. This was my first formal field research experience, and one I found both interesting and rewarding. I am excited to continue analysis of my
