Work in the Ayse Gurses Lab examines several topics related to human factors, including methods for improving patient safety in the cardiac operating room, care coordination, transitions of care and compliance of providers with evidence-based guidelines. Our team also has an interest in research that explores the working conditions of nurses. We collaborate on studies related to the development of geriatrics health service delivery at all levels of the health system.

Work in the Christopher Chute Lab involves the management of clinical data to enable effective evidence-based clinical practice and translational research. Recently, we developed an EHR-based genetic testing knowledge base to be integrated into the genetic testing ontology (GTO) and identified potential barriers to pharmacogenomics clinical decision support (CDS) implementation.

The GI Biomarkers Laboratory studies gastrointestinal cancer and pre-cancer biogenesis and biomarkers. The lab is led by Dr. Stephen Meltzer, who is known for his research in the molecular pathobiology of gastrointestinal malignancy and premalignancy. Research in the lab has led to several groundbreaking genomic, epigenomic and bioinformatic studies of esophageal and colonic neoplasms, shifting the gastrointestinal research paradaigm toward genome-wide approaches.

Research in the Liliana Florea Lab applies computational techniques toward modeling and problem solving in biology and genetic medicine. We work to develop computational methods for analyzing large-scale sequencing data to help characterize molecular mechanisms of diseases. The specific application areas of our research include genome analysis and comparison, cDNA-to-genome alignment, gene and alternative splicing annotation, RNA editing, microbial comparative genomics, miRNA genomics and computational vaccine design. Our most recent studies seek to achieve accurate and efficient RNA-seq correction and explore the role of HCV viral miRNA in hepatocellular carcinoma.

The Drug Development Unit (DDU) provides clinical research services and support to the faculty of the School of Medicine and to pharmaceutical sponsors. Our team of experienced investigators, nurses, and clinical research staff promote excellence in clinical trial operations. A wide range of services are available, from protocol design and clinical and laboratory support and data analysis, to administrative services including clinical trial agreement negotiation as well as IND and project management.

Researchers in the Harold Lehmann Lab study evidence-based medicine. We are currently examining the informatics infrastructure of research and the secondary use of electronic health record data for research. The team is also evaluating the value of classic evidence reports versus social media versus links to community services for community health workers.

Researchers in the Robert Greenberg Lab examine anesthesiology and critical care-related topics that include critical airway management, non-invasive fetal monitoring, neural blockade monitoring, pediatric acute pain management, cuffed oropharyngeal airway (COPA), pain informatics, and pediatric pain education and innovation.

The Abadir Lab focuses on uncovering the molecular mechanisms underlying frailty, resilience, and age-related diseases to bridge the gap between basic science and clinical applications. Grounded in translational research, the lab investigates the intricate interplay between mitochondrial biology, the renin-angiotensin system (RAS), and chronic inflammation, with an emphasis on their roles in physical and cognitive decline.

Key Areas of Research

1. Mitochondrial and Angiotensin Biology
   • Discovery and exploration of the mitochondrial angiotensin system (MAS) as a critical regulator of cellular energy, inflammation, and resilience.
   • Investigating age-related mitochondrial dysfunction and its contribution to frailty, chronic inflammation, and neurodegeneration.
2. Biomarker Development
   • Identification of novel biomarkers for aging-related frailty and resilience, including cell-free DNA fragments and kynurenine metabolites.
   • Development of diagnostic tools for early detection of physical and cognitive decline.
3. Innovative Therapeutics and Bioengineering
   • Designing nano-delivery systems for targeted drug delivery to mitochondria, enhancing wound healing and reversing cellular senescence.
   • Integration of artificial intelligence and engineering to create advanced diagnostic tools for assessing frailty and aging-related conditions.
4. AI and Technology in Aging
   • Leveraging artificial intelligence and bioengineering to address challenges in geriatric medicine through collaborations with the Johns Hopkins AI & Technology Collaboratory for Aging Research (AITC) and the Gerotech Incubator Program.

Our Approach

The Abadir Lab employs a multidisciplinary methodology, combining molecular biology, bioinformatics, and engineering to tackle the pressing health challenges of aging populations. By fostering collaboration between clinicians, scientists, and engineers, the lab ensures that discoveries translate into tangible benefits for older adults.

Translational Impact

With a focus on frailty, inflammation, and cognitive decline, the Abadir Lab contributes to the development of personalized interventions and precision medicine approaches. Our work has laid the foundation for:

• Repurposing drugs like losartan and valsartan for treating aging-related chronic wounds.
• Unveiling the role of mitochondrial dysregulation in Alzheimer’s disease and frailty.
• Innovating tools for clinical assessments of resilience and functional decline.

Collaborations and Mentorship

The Abadir Lab is committed to training the next generation of scientists, fostering an interdisciplinary environment where students and postdocs explore cutting-edge aging science. Collaborations with the Johns Hopkins GeroTech Incubator Program and the Translational Aging Research Training Program (T32) further enrich this ecosystem of innovation.
