647-1 Development of Global Optimization Techniques
Ian Bell, 303-497-6970, ihb[at]boulder.nist.gov
The need for global optimization of non-convex functions is ubiquitous throughout the worlds of science and engineering. There are many approaches that have been developed for this challenging task, among which are nature-inspired techniques like evolutionary optimization, particle swarm optimization and so on. We are looking for a student with an interest in optimization of nonlinear functions to improve our capabilities in global optimization. Though we are primarily focused on the development of models for thermophysical properties, this project takes a more broad view of optimization, and looks to extend existing generalized open-source optimization tools developed in our group. Experience with C++ and/or Python is preferred, but not required.
647-2 Properties of Absorbent Materials Relevant to New Breath Sampling Devices
Kavita Jeerage, 303-497-4968, jeerage[at]boulder.nist.gov
Sorbent materials such as polydimethylsiloxane (PDMS) are used to capture hydrophobic chemicals in passive air sampling devices, solid phase microextraction devices, and even breath collection devices. Determining the concentration of chemicals of interest in the original air or breath sample requires knowing its partition coefficient. The SURF student will determine partition coefficients for aromatic chemicals by gas chromatography retention time measurements. Students with analytical chemistry or chemical engineering backgrounds are encouraged to apply.
647-3 Vapor Pressure Measurements of Aroma Compounds
Tara Lovesteady, 303-497-5614, lovestead[at]boulder.nist.gov
Terpenes are a large group of volatile hydrocarbons produced by trees, medicinal plants, and some insects. They have many potential applications, including as natural agricultural pesticides, in the fragrance and flavoring industries, and even as alternative fuels. Designing and optimizing industrial processes for terpenes of interest requires knowing their vapor pressures. The SURF student will determine vapor pressures with a custom-built apparatus and will utilize gas chromatography with flame ionization detection. Students with analytical chemistry or chemical engineering backgrounds are encouraged to apply.
647-4 Behavior of Chemical Systems Containing Electrolytes
Vladimir Diky, 303-497-5273 diky[at]boulder.nist.gov
Chemical systems containing electrolytes show complex and subtle phase and property behavior. Our group models chemical systems by applying a combination of data science and fundamental modeling, and is expanding into this area. An affiliate working with us will gain experience in data structuring, experimental validation and fundamental understanding of these systems. Opportunities exist for experienced programmers as well as those more inclined toward pen-and-paper or Excel.
647-5 Surveying Salt Bridges Involving Histidine in the Protein Databank
Demian Riccardi, 303-497-4648, riccardi[at]boulder.nist.gov
The pKas of the histidine (HIS) and aspartic acid (ASP) sidechains result in a cost of ~10 kJ/mol for the HIS to ASP proton transfer. Heterogeneous electrostatic environments, found in proteins, greatly modulate this free energy difference. This project will survey the Protein Databank for HIS/ASP salt bridges to determine factors that promote or perturb these interactions. The ideal candidate will have a strong interest in biophysical chemistry and have programming experience.

Chris Nelsen, 303-497-3728, chris.nelsen[at]nist.gov
The rapid proliferation of internet-connected devices and rise of the Internet of Things (IoT) come with great anticipation. These newly connected devices bring the promise of enhanced public safety information collection, sharing, and analysis. Researching the processes to protect sensitive data will help ensure first responders cultivate trust in the innovative tools that are currently being developed. A SURF student will research different scenarios, hardware, and processes for IoT data transmittal and storage to provide an in-depth analysis, demonstrating the risks associated with these processes. This analysis will show the ability to compromise the data or provide access to unintended recipients, implications of the data being compromised, and best practices to implement these devices in a first responder community. Special attention will be dedicated to how these risks affect law enforcement and justice system requirements for “chain of custody” for data collected from IoT devices.
671-3 Open Innovation Challenge Research and Business Systems

PSCR’s Open Innovation (OI) Team focuses on advancing public safety communications research by leveraging the expertise and innovative solutions from a diverse array of contributors and collaborators across the globe. The SURF participant will work with the OI Team on concept and design research for new prize challenges; version control and auditing of the OI Team’s standard operating procedure (SOP); targeting outreach and communications; and developing business solutions including technology transfer. The SURF participant will work closely with OI prize managers and engineers to refine ideas and develop presentation materials. For the SOP version control and audit, the participant will work closely with the OI’s project manager using Huddle, Salesforce, and other internal tools.
671-4 PSCR IoT Protocol Analysis and System
Donald Harriss and Allison Kahn, 303-497-5880, don.harriss[at]boulder.nist.gov
The Internet of Things (IoT) remains a desegregated technology with deficiencies that inhibit or limit use in First Responder Networks. Limitations include lack of standardization among data types and formats, vendor specific communications protocols, weak security mechanisms and poor ruggedization or resilience implementations. This project will study these deficiencies and focus on protocol analysis such as Bluetooth, Zigbee, WiFi and other wireless standards. A comparison matrix ranking usability and standards implementation shall be conducted in conjunction with integration potentials. System adaptation will be conducted against laboratory systems, such as log collectors, protocol analyzers, IoT publishers and IoT dashboards. A student in this project will have to opportunity to analyze IoT protocols, utilize network or socket application development and integrate IoT devices into a ubiquitous, presentable and usable display center.

The development of experimental quantum computers is rapidly accelerating, with increasing numbers of quantum bits and operations with higher fidelities. However, characterization of these devices is a challenging statistical problem. We are developing algorithms and writing software to characterize the quantum bits and logic operations in quantum experiments at NIST. This will be a good opportunity to gain practical programming experience and learn both quantum theory and statistics.
