Scalable Bayesian inference for structural equation models
Academic Program: Statistics
This project aims to equip latent structural equation models with a powerful and highly efficient Bayesian inference engine called INLA (www.r-inla.org), a state-of-the-art computational framework that delivers the speed and scalability of modern machine learning while preserving the interpretability and flexibility of traditional statistical models. Leveraging INLA’s capabilities for structural equation models and the like will unlock a new wave of scalable, domain-ready tools that expand the reach and relevance of latent variable analysis. The public good is substantial: more accurate diagnostics in healthcare, better-targeted interventions in education, and smarter decision-making in digital and data-driven industries.

Conversation 3D Visualization on the Web
Academic Program: Computer Science
Conversational visualization can be characterized as an integration of interactive visualization with large-language models (LLM) through prompting or fine-tuning strategies. We have recently developed several web-based visualization systems for volume visualization (tomography.kaust.edu.sa) and for visualization of atomistic models (mesocraft.kaust.edu.sa).
The task for this project will be to integrate these visualization systems with client-based web-based LLMs (or alternatively with server-based LLM inference) and with speech recognition, so that these conversational capabilities extend the interaction metaphors based on mouse and keyboard interactions.

Mathematical and computational explorations of the induced earthquake nucleation process
Academic Program: Earth Science and Engineering
Induced seismicity is a central issue in the development of subsurface energy technologies in the United States and around the world. It is basically the earthquakes caused by human activities that involve extracting or injecting fluids into the subsurface and modifying subsurface stresses around pre-existing faults. Examples include subsurface wastewater injection, reservoir impoundment in the vicinity of large dams, development of mining, geothermal or hydrocarbon resources, and in geologic carbon sequestration. While most of the induced earthquakes are fortunately too small to be felt, some can go up to magnitude 5 — large enough to be felt and to cause damage to buildings. Understanding the physical mechanisms behind induced seismicity is essential to successful management and mitigation of the seismic risk associated with subsurface energy technologies.
The basic mechanism for induced fault slip is widely understood in terms of the Coulomb failure criterion. When fluid is injected into or withdrawn out of a reservoir, the associated pore pressure perturbations and poroelastic stress changes increase the ratio of shear to effective normal stress on a fault and cause it to slip. This criterion, however, does not address the evolution of the rupture, and whether a fault slips seismically or aseismically. A different criterion, derived from theoretical analyses of frictional slip between two elastic media, differentiates from seismic and aseismic slip. It states that fault slips seismically if the spatial scale for the slipping zone is larger than a critical nucleation length inversely proportional to the effective normal stress, and slips aseismically otherwise. This criterion, however, assumes spatially and temporally uniform effective normal stress and does not take into account the dependence of friction on fluid presence.

Statistical properties of induced earthquakes
Academic Program: Earth Science and Engineering
Induced seismicity is a central issue in the development of subsurface energy technologies in the kingdom and around the world. It is basically the earthquakes caused by human activities that involve extracting or injecting fluids into the subsurface and modifying subsurface stresses around pre-existing faults. Examples include subsurface wastewater injection, reservoir impoundment in the vicinity of large dams, development of mining, geothermal or hydrocarbon resources, and in geologic carbon sequestration. While most of the induced earthquakes are fortunately too small to be felt, some can go up to magnitude 5—large enough to be felt and to cause damage to buildings. Quantifying the statistical properties of induced seismicity is essential to successful management and mitigation of the seismic risk associated with subsurface energy technologies.
A fundamental statistical relationship in seismology is the Gutenberg-Ricter frequency-magnitude relation. It describes the frequency of earthquakes as a function of their magnitude. It is usually expressed as: log10 N = a - b M, where N is the number of earthquakes with magnitude ≥ M, a is a constant that represents the total seismicity rate in a given region and time period, b is the b-value, typically around 1 for natural earthquakes, which characterizes the relative likelihood of small versus large earthquakes, and M is the earthquake magnitude. The b-value associated with induced earthquakes is a subject of ongoing debate and uncertainty.

Experimental review of fluid pressure effects on sheared granular materials
Academic Program: Earth Science and Engineering
Natural faults are typically viewed as rock surfaces filled with fluids and wear detritus, called fault gouge. In the laboratory, there is an apparent discrepancy in frictional behavior between observations of sliding on bare rock surfaces and shearing granular gouge materials. Experiments on bare rock surfaces and rock surfaces separated by a thin layer of gouge indicate that slip between two rock surfaces is much more stable at high than at low fluid pressure. In contrast, the majority of experiments on granular gouge materials indicate that slip is less stable at high than at low fluid pressure. While some studies speculate on the role of dilatancy in the frictional behavior of fluid-filled gouge materials, the exact explanation behind this discrepancy is unclear.

Hunting Microplastics-Transforming Enzymes in Mangrove Soils Metagenomes
Academic Program: Marine Science
Mangrove ecosystems are vital for carbon storage and climate regulation, but they are increasingly threatened by microplastic pollution. Despite their rich microbial diversity, the impact of microplastics on mangrove soil microbiomes remains underexplored. This project aims to build a global catalogue of genes from mangrove soil metagenomes and to develop computational strategies to identify and rank putative PET-transforming enzymes. The outcomes will advance our understanding of microplastic degradation potential and microbial ecology in mangrove ecosystems.

Volcanism of the Northern Red Sea
Academic Program: Earth Science and Engineering
This project is in the Volcanology Igneous Petrology and Geochemistry group of Prof. Froukje van der Zwan. The Red Sea is formed by spreading of two plates, whereby the Red Sea axis respresents the mid-ocean ridge spreading center. Where the southern Red Sea the mid-ocean ridge is well exposed, in the northern Red Sea it is partially covered by salt flows, and therefore much less is known about the formation of the mid-ocean ridge and about the volcanism that builds it. The student will work with basalt samples recovered in previous expeditions from the northern (and central) Red Sea and do petrological evaluations under a microscope and perform geochemical analyses such as XRF and ICPMS, including the preparation of the samples for these analyses. Using geochemical data, aim is to understand the source of the magma, magmatic processes and the volcanic expressions of the magmatism.

Uncovering and Addressing Bias in LLM Interactions
Academic Program: Computer Science
Large Language Models (LLMs) have become ubiquitous in contemporary applications. They are trained on extensive collections of human writings, ranging from books, papers, and news articles to conversations on social media platforms. This comprehensive approach enables the development of sophisticated tools capable of emulating human interactions with remarkable fidelity. However, it is important to recognize that LLMs might inherit and perpetuate the biases inherent in human communications.
This project represents a concerted effort to delve deeply into the multifaceted landscape of biases inherent in interactions with LLM agents. By examining various dimensions of biases, we aim to explore how these biases manifest within LLM-mediated interactions. Through this project, we would not only understand the complexities of bias within LLM interactions, but also explore the possibility to mitigate, neutralize, or rectify these biases. This will underline if LLMs are more inclined to change opinions than humans. This approach underscores our commitment to fostering fairness, equity, and inclusivity in the realm of LLM-driven communication and interaction, ultimately advancing the societal impact and ethical integrity of LLM technology.

Academic Program: BioScience
The StruBE synthetic biology team is harnessing the power of proteins to forge innovative tools for biotech and medical applications. We are collaborating with material scientists and chemists to embed our designer proteins in novel materials or bioelectronic circuits. Ongoing projects include the design of next-generation biosensors, smart drugs, targeted therapeutic protein degrading systems, and designer enzymes for industrial applications. This entails experimental and computational work as well as the development of robotic liquid handling workflows. On the experimental side, a prospective student will be involved with protein production from E. coli or mammalian cell culture and the biophysical characterization of protein-protein interactions or enzymatic (whole-pathway) reactions. Prior wet-lab experience is a plus. A computational project in support of protein design and lab automation would require prior knowledge in Python programming. Hence, the interdisciplinary projects can host students from various backgrounds, e.g. from biochemistry, (bio)engineering, protein structural biology, or computer science.
