Artificial Intelligence and Machine Learning
We use Artificial Intelligence and Machine Learning to provide critical capabilities to our advanced systems in the space, security, and military domains. However, an overarching challenge of using AI/ML in these domains is sparse, irregular, non-representative, or incomplete training data sets. Another challenge is building calibrated trust between the systems and users to prevent critical errors and increase adaptability into operations. Our team seeks methods to advance the state of the art in this field.
We would be targeting Ph.D. students for the development of novel approaches and M.S. students for the application of existing approaches to specific problems of interest.

Operational AI/ML with Imperfect Data Sets
Training successful AI/ML algorithms, especially deep learning models, requires large, comprehensive data sets similar to those collected in operation use conditions. In many of our domains of interest, generating large sets of training data is infeasible because historically, there are fewer examples and events of interest are infrequent or unique. Additionally, many missions are fast-paced with high levels of uncertainty. Any AI/ML models must be trusted to operate in a way that increases accuracy and efficiency without causing critical failures or introducing unnecessary burdens to the user. Example applications that are of interest to us include:
a) Advanced Autonomy – enabling autonomous systems or agents to perform accurately and robustly in novel, complex, or uncertain situations.
- Collaborative control, tasking, navigation, or decision making
- Scene understanding and analysis, including multi-sensor integration, object persistence, contextual reasoning, and threat characterization
- Mission planning, mission management, and decision support

Celestial Navigation
The ability to measure celestial objects across different spectral regions, using advanced imaging processing techniques, utilizing ultrasensitive detection techniques, and/or leveraging adaptive optics can enable significant increases in observational capacity and ultimately better positional accuracies. We seek to foster several different modalities that can improve the imaging of celestial objects (including those in Earth's orbit). Some questions that we are interested in are:
- How can non-centrosymmetric optics be used to improve compact telescope designs (particularly by removing obscurants)?
- Can size-, weight-, and power-constrained focal plane arrays be built that examine multiple spectral regions? Can multiple focal plane arrays be used in highly limited form factors to increase spectral ranges?
- Are there novel methods for sensing and correcting incoming light through highly degrading environments or rapidly changing conditions?
- How can the field of view be maximized while limiting or eliminating aberrations (spherical, chromatic, etc.)? Are there techniques, methods, or processes for achieving very high fields of view?
MEMS-Based Navigation
MEMS sensors have achieved success in commercial and other high-volume applications. We are seeking to use MEMS technologies for precision applications. We are interested in advancements in the following areas:

- Development of discrete-mass, in-plane oscillator gyroscopes.
- New MEMS gravimeter designs that outperform existing mechanical gravimeters.
- Packaging and mounting technologies for MEMS sensors where mounting stresses in MEMS technologies are minimized.
Edge Sensing Methods
A key challenge for APNT is distinguishing critical data from meaningless data. Traditional sensors accept all data that surpasses their detectability limits, which means that they are always on (power hungry) and are constantly outputting data (which necessitates processing capabilities).
The use of new methods, such as AI/ML, neuromorphic sensors, sparse sampling, and multi-hub/multi-node webs can help mitigate this data avalanche at the edge of the sensor/phenomena interface. We seek insights into the following questions:
- How can we use edge sensing/data fusion methods to reduce sensor power consumption and sensor failure rates?
- Can we use neuromorphic sensing methods to significantly evolve/change sensor functionality and operation without human intervention?
- For a given detection system, can we significantly improve processing capacity but still maintain overall detection capability by reducing irrelevant sensor outputs?
Clocks and Timing
Atomic and molecular systems provide a set of highly precise and accessible energy levels that can be used for precision timing. Some questions we are seeking insight into are:
- How can we reduce the size of chip-scale atomic clocks? Can we move to higher frequencies (e.g., terahertz) for intra-atomic coupling?
- How can we rapidly and accurately synchronize multiple independent clocks that are spatially separated?
- Beyond the commonly used systems, what other atomic or molecular gases have the potential to achieve very high timing precision? Can the ancillary support structures also be miniaturized and packaged?
Quantum Sensing
We seek advancements in atomic and molecular sensing of electric and magnetic fields, such as:
- Use Rydberg atoms to simultaneously sense electric (RF) and magnetic fields. Can detectability be increased? Can the detection be shown to be vectorized?
- Atomic gravimetry for precision sensing of gravity in highly constrained (size, weight, and power) packages and/or unstable platforms (e.g., moving vehicles, airplanes, ships, etc.).
- Use atomic or molecular gases for very high precision magnetic field detection (magnitude or vectorized).
- Low-dimensional materials for sensing acoustics (air or underwater) at very specific frequencies (narrowband) and very high detectability.
- Ionic, atomic, dopant, or vacancies in materials that can be used for magnetic field sensing, such as nitrogen vacancies in diamond, dopants or inclusions in optical fiber for Faraday rotation detection, or magnetic dopants in quantum dots.
Quantum Materials
A new generation of materials has shown that when the material size becomes similar to or less than the size of relevant quantum wavefunctions, new capabilities and novel physics can be achieved. We seek a greater understanding of how room-temperature phenomena in these materials can be used in chip-scale packaging for very sensitive detection or manipulation of electric, magnetic, acoustic, optical, or quantum behaviors. Topics may include:
- Spontaneous self-assembly of materials to form a simple device or sensor.
- High-performance materials (e.g., graphene, topological insulators, phase-change materials, etc.) that can be used for sensors that manipulate light.
- Electrical control of light-matter interactions, such as rapid control over indices of refraction, high-speed manipulation of reflection/absorption/transmission, or coherent energy transfer to/from incoming light in a narrowband frequency region.
- Materials that can be used for novel acoustic sensors.
Photonics-Based Navigation
The use of precision-controlled light using unique geometries and tailored refractive indices enables a radical reduction in the size, weight, and power across the APNT spectrum. We seek to explore topics in photonics such as:

From multi-week duration underwater vehicle missions to spacecraft mission planning, real-time planning for autonomous parafoils, or multi-agent ground and air vehicle cooperation, we apply autonomy across many domains and at all technology readiness levels. Our team continues to seek cutting-edge ideas and technologies to push the state of the art forward.

We seek frameworks applied to multiple agents that do not merely enhance single-vehicle capabilities, but additionally, enable new mission designs and revolutionary advances in autonomous team achievements.
Optimal Teaming Formulations and Battlespace Planning
In large and complex engagements, many open questions remain when incorporating autonomous agents with operators, decision-makers, and planners. Some questions we are seeking insight into are:
- What level of centralization vs. decentralization in command and control is optimal in an engagement? How does this change as the environment, enemy, and resources evolve?
- What level of autonomy should be given to agents in a large operation? How does this change as the environment, enemy, and resources evolve?
- What is the optimal teaming formulation (crewed, uncrewed, crewed-uncrewed) to complete an objective? How does this change as the environment, enemy, and resources evolve? How is the trade-off between completing this mission vs. reserving resources for future engagements made?

We seek planning and decision-making frameworks that have an awareness of system uncertainty and can present operators with optimal plans including knowledge of uncertainty before and after planned actions.
Advanced Simulation, Verification, Validation, and Field Testing
Although our team has been successful in fielding autonomous systems across domains, we are constantly seeking ways to decrease the development and fielding times while increasing our robustification, continuous testing, and V&V capabilities. To meet the increasing performance guarantees required by these advanced autonomous systems and our customers, we are seeking research Ph.D. and MS-level research in simulation, V&V, automated field testing, and enabling advanced autonomy architectures.
AI in Autonomy
Even though there have been significant advances in AI-based autonomy over the past decade, there are still areas that warrant additional research to increase the field-worthiness of these proposed approaches. Specifically, our team seeks AI research in the sub-fields of mission planning, explain-ability and robustness measures, AI-based planning and battlefield estimation heuristics, GN&C, and swarm tactics.

Biosurveillance
Infectious diseases are one of the largest threats to global public health. Factors such as climate change, increased population growth, expansion into animal habitats, and prevalence of antimicrobial resistance have led to the emergence of novel pathogens as well as the rise of previously controlled infections. The ability to rapidly monitor the spread of disease is crucial for prevention, interference, and control. With the emergence of SARS-CoV-2, wastewater surveillance has shown to be a useful rapid approach for monitoring disease spread and levels in the community. Additional pathogens are detectable in wastewater, allowing for the monitoring of multiple circulating pathogens. The principles of wastewater biosurveillance can extend beyond the public to government agencies to help monitor safety and threats against key assets and locations in addition to other complex environmental samples. The development of rapid pathogen agnostic detection is necessary to protect communities against and prevent the spread of novel infectious threats.

The principles of wastewater biosurveillance can extend beyond the public to government agencies to help monitor safety and threats against key assets and locations in addition to other complex environmental samples. The development of rapid pathogen agnostic detection is necessary to protect communities against and prevent the spread of novel infectious threats:
- The development of new organ models beyond our current portfolio, particularly in neural and cardiac models.
- The integration of immune components into organ models.
- The development of new disease models such as for thrombosis and coagulopathy applications.
- Automation of downstream assays via innovations in microfluidics and related domains is also key to driving down the costs and increasing the throughput of these model systems. Advancements in organ-on-chip technologies will enable rapid response to emerging threats and improve medical countermeasure development.
Development of High-Fidelity Multi-Omics Capabilities
Modeling emerging threats and developing mitigation strategies requires an ever-advancing set of capabilities for analyzing data obtained from clinical samples, preclinical animal studies, and model systems such as organs on chips. Conventional analytical tools provide a limited window into the dynamics of pathogenesis, including entry, replication, and immune downregulation, resulting in a dearth of countermeasures despite years of research. Novel capabilities in single-cell analysis and in capturing and probing multi-omics datasets including proteomics/genomics, epigenomics, and the microbiome, will be critical in designing increasingly complex and powerful model systems for the investigation of disease mechanisms and evaluation of therapeutic approaches. Integration of these multi-omic readouts at both the tissue and single-cell levels will ultimately accelerate response to emerging threats, reduced costs, and wider availability of vaccines and therapeutics during health emergencies.

This would advance U.S. manufacturing by decreasing development costs and increasing reliability across many business sectors including electronics, biotechnology, and aerospace applications. Current approaches using microscopic models are difficult to integrate at the system level. We aim to develop a lumped element, plug-and-play non-linear model of polymer materials for COMSOL-type environments.

The ability to quickly screen or evaluate novel materials facilitates their rapid development, which would otherwise require extensive and challenging testing to gain significant insight. Pre-screening candidates can help focus experimental work on the most promising options
Photonics Packaging
We have a core interest in precision navigation and timing, with many of these systems utilizing optical components. Recent advances have enabled photonic integrated circuits (PICs) to integrate numerous optical components on a single chip. Packaging these PICs presents a considerable challenge due to the difficulty of coupling light on and off the PIC. Various methods are being explored to facilitate convenient optical packaging.
Technical Point of Contact
Research Interests
Photonics Packaging
Better methods would allow:
- Automated attachment
- A large number of optical connections
- A very large number of electrical connections (ex. bump bonding).
- Compatibility with different waveguide material systems (Silicon, III-V, LiNbO3, garnet)
- Vertical optical coupling to free space (for LiDAR or
- Free Space Optical Communication applications)
- The ability to couple to different mode shapes and sizes
- The ability to add and remove disposable PICs in the field
It is unlikely that a single method can simultaneously serve all these needs, but they do impact systems in which we have an interest. We prefer, therefore, to meet all these needs with as few unique methods as possible. Many institutions are actively researching improved optical coupling methods to meet the needs shown in Figure 1.
Methods can be divided into two categories, depending on whether they couple light from the edge of the chip or from above. The most common method for coupling light from above is by using a grating. This method lends itself to standard planer fabrication methods but is limited in efficiency and bandwidth. A technique with better performance in these areas is shown in Figure 2. This method uses a 3D mirror to both direct and focus the light above. The fabrication of such a mirror is challenging and we are exploring an alternative method to fabricate integrated mirrors. This method uses the self-assembly of gold nanoparticles, functionalized with DNA, to create pyramids aligned to wells in the substrate, as shown in Figure 3.
This method of light coupling is of interest, as well as other methods, such as adiabatic tapers, photonic wire bonding . Also of interest are the aspects of packaging other than light coupling, such as the physical packaging itself and improved methods for alignment.

New processes and technology nodes, such as the 12LP process from GlobalFoundries or gate all around (GAA) field effect transistors, show promise for producing radiation-hardened devices. Systems that require rad-hard technologies typically also require high-reliability performance. These new processes need to be characterized for both reliability and radiation hardness in a variety of environments. Similarly, existing high-reliability processes (e.g., automotive devices) should be evaluated for radiation hardness in the natural space environment (NSE).
Example areas might include:
- Experimental characterization of devices made on various SOTA technology nodes.
- Evaluation of neutron single event effects (nSEE) for different nodes and processes across multiple neutron source spectra.
- NSE evaluation of high-reliability components and sensors. For example, automotive parts for use in space.
Novel Approaches to Sensitive Components
Certain components required in a system are more sensitive to radiation than others. These devices are critical to the operation and often require significant compromises in system design to accommodate them. The development of novel approaches that bring about transformative changes in the state-of-the-art would enable a variety of new applications and approaches to address our key challenges. Critical devices we are interested in include power conversion technology, non-volatile memory, and precision voltage and timing references.

Navigation Sensors
The ability to navigate a spacecraft is critical to all space missions. We are interested in architectures and technologies (both hardware and software) to support autonomous precision navigation in cis-lunar space (including on the lunar surface). Approaches that enable new missions, or fill gaps in current mission concepts, minimize size, weight, and power (SWaP), and can operate autonomously for extended durations in deep space are of particular interest. Again, we may share specifics of particular interests once the collaborative research topic has been agreed upon.
Space Situational Awareness
The ability to be situationally aware in space (SSA) requires unique space-based sensors with innovative sensing modalities, mixed sensor suites, and algorithms for the detection, identification, and tracking of objects in both near and far proximity to a space asset (e.g. CubeSat). Our team is interested in novel sensors, algorithms, and system approaches to SSA for LEO through to cislunar domains. We may share specifics of particular interests (e.g. field of view; field of regard; accuracy; etc.) once the collaborative research topic has been agreed upon.
Fault-Tolerant Computing
Fault-tolerant computer architectures satisfy NASA safety requirements by providing the reliability and redundancy necessary for human-rated NASA systems, enabled by highly reliable computing elements. These are also required for commercial and science missions that must have mission availability. We are investing in technologies such as our software-based redundancy management (which was developed for NASA’s Space Launch System) and highly reliable electronics to meet the growing need for edge-computing and/or high reliability/fault tolerance in space. We are interested in advances in technologies, algorithms, and approaches to fault-tolerant computing and architectures to support these needs, including radiation hardening and high-temperature electronics. As with the prior research areas, our team may share specifics of particular interests once the collaborative research topic has been agreed upon.
Terrain Relative and Vision-Aided Navigation
Our vision-aided navigation (VAN) and terrain relative navigation (TRN) areas have been developed for terrestrial (air and ground), undersea, space-based orbital and landing applications, and wearable technology. The technology is most useful in GPS-denied and lighting-constrained areas. Advancing this technology requires utilizing new sensors in GPS-denied environments, increasing the robustness and accuracy of the measurements, advancing the simulation systems to test the measurements, and seamlessly integrating the measurements with existing navigation systems.
We would target Masters and Ph.D. students. As an example, Masters students can perform design sensitivity studies, and Ph.D. students can develop novel algorithm approaches.
