Juliane Beier, PhD | JIBEIER@pitt.edu | Dr. Beier's research program investigates interactions between environmental chemical exposures and lifestyle factors that increase risk of chronic liver disease. This work addresses how common dietary patterns and background health conditions transform manageable environmental exposures into severe hepatotoxic crises. The laboratory examines complex environmental chemical mixtures that reflect real-world exposures. The "Rust to Resilience" (R2R) research program investigates how legacy toxicants (lead, cadmium, arsenic) combined with emerging PFAS chemicals interact with Western dietary patterns to cause severe liver injury and activate carcinogenic pathways. Novel research examines how inhaled environmental toxicants cause rapid-onset liver pathology. Work on simulated military burn pit exposures demonstrates that inhalation of complex combustion emissions causes immediate hepatic dysfunction and cellular damage within two days of exposure. Following the East Palestine, Ohio chemical disaster, the first systematic liver function assessment in residents potentially exposed to vinyl chloride and other hepatotoxic chemicals was initiated, establishing critical baseline data for long-term health monitoring. Investigation continues into how underlying metabolic conditions—affecting over 30% of Western populations—create permissive environments where environmental exposures trigger severe hepatotoxicity and activate carcinogenic pathways. Available Graduate Projects: 1. Mechanistic studies investigate organelle dysfunction, epigenetic modifications, and transcriptomic pathway analysis to understand how environmental exposures alter liver disease progression. 2. Carcinogenesis research determines mechanisms by which low-level vinyl chloride and chemical mixtures promote tumor formation in metabolically compromised liver tissue. 3. Therapeutic intervention projects develop pharmacologic and genetic approaches to prevent or treat toxicant-diet interactions, while advancing sensitive biomarkers for early detection of environmental hepatotoxicity. 4. Environmental health surveillance conducts community-based research and develops rapid-response methods for environmental disasters. Translational Impact This research program bridges fundamental mechanistic studies with real-world environmental health challenges, providing critical insights for public health policy, environmental risk assessment, clinical biomarker advancement, and community health protection. Graduate students gain experience in RNA-sequencing, inhalation toxicology, electron microscopy, and community-based research methods while addressing pressing environmental health questions. |

Stephen Chan, MD, PhD, FAHA | chansy@upmc.edu | Stephen Chan, MD, PhD, is a physician-scientist and cardiologist who leads a research program and clinical center investigating mechanisms of pulmonary hypertension (PH), endothelial biology, and heart-lung-brain axis communication in health and disease. He combines molecular and clinical bioinformatics with unique rodent and human experimental reagents to accelerate systems-wide discovery in vascular disease. Chan defined the genetic and acquired mechanisms of altered metabolism in PH, identifying iron-sulfur deficiencies and glutaminolysis as key disease drivers. This work serves as a basis for glutamine restriction as a dietary therapy for PH; clinical development of 18F-glutamine tracer for positron emission tomography (PET) diagnostic imaging; and formation of a biotech company testing therapeutic glutaminase inhibitors in humans. Chan also identified regulatory processes of inflammation and mechanosensing in PH. He was the first to demonstrate the systems-level importance of non-coding RNAs in PH. Chan established a genetic and metabolic paradigm that links lysosomal biology and oxysterol generation to endothelial inflammation and PH. He defined metabolomic signatures identifying persons at-risk for PH mortality and developed new lysosomal therapies for vascular disease. Dr. Chan published these seminal basic and translational discoveries across journals like Science, Cell, Cell Metab, J Clin Invest, Sci Transl Med, Circulation, and Circ Res. Dr. Chan served as primary mentor for >35 trainees with success across career development and independent research. He founded a humanitarian telemedicine organization, the Addis Clinic, serving east Africa. Finally, Dr. Chan directs the Pittsburgh Vascular Medicine Institute and was elected as ASCI Vice President, becoming President in 2027. |

Mark Miedel, PhD | mmiedel@pitt.edu | My research uses human biomimetic liver microphysiological systems (MPS) to model both normal and disease-state liver physiology. My focus is on implementing the coupled use of liver MPS with quantitative systems pharmacology (QSP) as an integrated platform for identifying mechanisms and biomarkers of MASLD/MASH disease progression and as a drug testing platform to inform precision medicine therapeutic strategies for drug discovery that can be applied to select patient cohorts using patient-derived primary and/or iPSC liver cells. Using this approach, we have identified key differences in MASLD progression and response to therapeutics in liver MPS constructed with patient cells harboring the PNPLA3 I148M mutation, a key known genetic variant known to be associated with more severe MASLD phenotypes. I also have interest in utilizing liver MPS to examine the impact of the liver tumor microenvironment on metastatic phenotypes that are associated with the progression of different cancer types (metastatic melanoma and breast cancer) as well as using 3D bioprinting technology to generate higher throughput liver MPS for larger drug screening efforts. |
