QiLiang “Q” Chen
Assistant Professor of Anesthesiology, Perioperative and Pain Medicine (Adult Pain)
Current Research and Scholarly InterestsMy research focuses on understanding the plasticity in pain-modulating circuits in pathological pain states. I started with defining a basic functional framework that links the pain-transmission system to the pain-modulation system, through which I explored the central mechanism of sensitization in chronic pain after a peripheral injury. Based on this fundamental observation, my work now focuses on investigating the pathophysiology and the role of endogenous opioids in chronic pain related to brain injury and other forms of trauma, a topic especially relevant to chronic post-traumatic pain sufferers. Clinically, I am exploring the use of advance image-guidance in pain interventions for treating complex headache and craniofacial pain. Ultimately, I hope to translate these fundamental knowledge and technologies to patient care and provide potential new therapeutic targets to help those with pain after head injury and polytrauma.

Sijie Chen
Postdoctoral Scholar, Radiation Physics
BioI am a postdoctoral fellow working with Dr. Lei Xing at Stanford University, where I develop trustworthy autonomous AI agents and foundational informatics systems for single-cell biology. My long-term vision is to build auditable computational infrastructure and virtual cell models that transform massive single-cell atlases into reliable, steerable systems for mechanistic discovery across tissues, diseases, and species. My doctoral work with Prof. Xuegong Zhang established my foundation in single-cell bioinformatics and atlas-scale integration, which I have since extended into large-scale representation modeling, AI agent workflows, and LLM-driven scientific discovery. My current work focuses on developing governed, agentic lifecycles for continuous single-cell data curation and foundation model evaluation, while applying these autonomous systems to power cross-organ virtual cell retrieval and simulate immune-tolerance breakdown.
My ongoing efforts build directly upon my prior work in atlas integration and algorithmic development. As the first author of hECA (Chen et al., 2022), I built a unified human cell atlas integrating one million high-quality cells across 38 organs with a logic-expression query interface. This experience exposed the central bottlenecks—such as heterogeneous formats and ontology grounding—that I now address using LLM-powered agents to enable autonomous metadata harmonization and iterative quality control. I am converting manual curation into an autonomous, agent-driven paradigm where new datasets are continuously ingested and versioned in a traceable manner. Furthermore, my co-development of TorchGW for cell state alignment, TFcomb for perturbation prediction, and TransMap for cross-species alignment provides the algorithmic foundation for next-generation cell foundation models and virtual cell simulation.
By integrating these components into trustworthy, benchmarked, and human-in-the-loop AI infrastructure, my research bridges scalable scientific computing with complex biomedical questions. Through close collaboration with Prof. Edgar Engleman, I am utilizing immune-tolerance breakdown—specifically focusing on a tolerogenic dendritic cell program—as a mechanistic testbed to validate our virtual cell simulations. A core focus of my work is ensuring that every agent-generated hypothesis and retrieved state remains bound to the exact data and model checkpoints that produced it, making findings fully re-derivable as the biological knowledge base evolves. Ultimately, I aim to advance the frontier of trustworthy autonomous single-cell informatics, bridging AI agents, virtual cell engineering, and biological discovery. -

Paul Cheng MD PhD
Assistant Professor of Medicine (Cardiovascular Medicine)
BioDr. Cheng is a Cardiologist at Stanford University School of Medicine in the Department of Medicine and a member of the Cardiovascular Research Institute. Dr. Cheng received his BEng in Chemical Engineering and BSc in biology at MIT. He subsequently completed his MD/PhD at UCSF working in the Srivastava lab studying how extracellular morphogenic signals affect cardiac development and fate determination of cardiac progenitors. Dr. Cheng completed internal medicine residency and cardiology fellowship at Stanford, including a post-doctoral training in the Quertermous lab. His current clinical focus is in amyloidosis and cardio-oncology.
Dr. Cheng pioneered the application of single cell transcriptomic and epigenetic techniques to study human vascular diseases including atherosclerosis and aneurysm, and applied these techniques to investigate molecular mechanisms behind genetic risk factors for several human vascular diseases including atherosclerosis, and aortopathies such as Marfan's and Loey-Dietz syndrome. The Cheng lab takes a patient-to-bench-to-bedside approach to science. The lab focuses on elucidating new pathogenic mechanisms of human vascular diseases through combing human genetics and primary vascular disease tissues, with high-resolution transcriptomic and epigenetic profiling to generate novel hypothesis that are then tested in a variety of in vitro and in vivo models. The lab is focused on two broad questions: (1) understanding the biological underpinning of the differences in diseases propensities of different arterial segments in an individual (i.e. why do you have atherosclerosis and aneurysms in certain segments but not others), and (2) understanding the role of perivascular fibroblast in human vascular diseases.
