CCI Technical Projects

Intern candidate would assist with the design, implementation, and testing of Perl or Python based components to be used with various cyber security applications. Individual would work with a professional cyber security team with more than ten years of development experience. In addition to structured program development, the individual would learn about intrusion detection and response, automated data analysis, databases, and network programming. Some knowledge of Perl, Python, databases, or general programming techniques is preferred.

Intern candidate would assist with the design, fabrication, testing, and assembly of research
equipment and systems for scientific staff at the Ames Laboratory. Duties might also include
incorporating as-built changes into original shop drawings and archiving drawings into database.
Individual will learn to work with computer aided design software and participate in the
conceptual design phase of project development and provide feedback on system design.

Intern candidate would learn current machining (lathe and mill) technique from a Senior
Engineering Research & Development (ERD) Machinist. Individual would work in a machine shop
environment and assist with machining projects in order to fabricate parts for scientific staff at
the Ames Laboratory. Individual would also learn welding techniques from a certified welder with
almost 50 years of experience.

Intern candidate would assist with the development, repair, and maintenance of electronic equipment and instrumentation used by scientific staff at the Ames Laboratory. Some knowledge of principles, methods, techniques, and tools used in the electronics field is preferred.

Intern candidate would assist senior research technicians with the assembly and operation of equipment for the melting and casting of metal alloys. Under general supervision individual will learn to work with vacuum systems; arc, induction and plasma melting furnaces. Work involves the operation and maintenance of specialized scientific research equipment.


Degradation of forensic evidence over time, or exposure of an evidence to accelerated corrosive environment impacts forensic match. Samples will be exposed to accelerated aging in a controlled environmental chamber with controlled humidity and pH. We will study limited case set to show the general trend of cyclic humid and warm condition, followed by cooling and freezing in wet environment. We will focus on the decay of the fracture surface topographic features. The surface topography will be measured at different deterioration levels for one of the fractured surface pair to assess the role of environmental aging on the match accuracy and on individual characteristics over time. The students will help assemble portions of the test fixtures. This project will also enable them to learn about various instruments and measurements for temperature and atmosphere. The student will be involved with design and set up of temperature – moisture-gas atmosphere tests to measure aging properties of metal.

The student in this CCI program will build and acquire technical skills and expertise in the general field of renewable energy generation, conversion and storage. Of particular emphasis will be technical know-how and expertise with the design of experiments and instrumentation to fabricate, characterize, and test CZTS-based devices for solar to chemical (photocatalysis) and solar to power (photovoltaic) energy conversion.

The student in this CCI internship will majorly focus on identifying the composition of chemicals from catalytic reactions. The student will be highly involved with analytical instrumentations, such as gas chromatograph, liquid chromatograph, mass spectrometer, and Fourier transform infrared spectroscopy (FTIR). The student will also learn how to identify the chemical formula and structure from the spectra using standards and structure database.

Engineering 3D biomimetic scaffolds that incorporate both biochemical and mechanical properties required for cell culturing is critical for many biotechnology applications. Hydrogel-based scaffolds are widely used due to their biocompatibility, tunable biochemical properties, and tissue-like water content. In contrast to hydrogels, microfibers have high mechanical strength and are used as the building blocks to create highly porous scaffolds. We are interested in exploring different fabrication processes for the development of the microfibers and will study the effect of fabrication parameters such as ejection rate, temperature, and time of pre-fixation on microfiber properties. The resulting scaffold morphology will be characterized using scanning electron microscopy and compression test.

We are developing two mass spectrometric imaging techniques: 1. to analyze plant metabolites in single cell level and 2. an analytical technique based on high-resolution mass spectrometry to understand complex bio-oils in molecular details. Knowledge on instrumental analysis is recommended but not required. Students will learn about mass spectrometry and bioanalytical chemistry technique that may be useful in their career.
