Dr. Ahmad M. Shaddad, MSc, MD (Chest Diseases) is an Associate Professor of Pulmonary Medicine at Assiut University, Egypt, with over 16 years of clinical, academic, and research leadership in respiratory and critical care medicine. He holds both Master’s and Doctorate-level training in Chest Diseases, reflecting a dual foundation in clinical practice and research methodology.

His academic trajectory is anchored in a distinctive, underexplored domain at the interface of pulmonary medicine and neuroscience. His doctoral (MD) thesis on neurological comorbidities in chronic obstructive pulmonary disease (COPD) established a comprehensive neurophysiological framework for understanding extra-pulmonary manifestations of respiratory disease. This work integrated advanced methodologies, including transcranial magnetic stimulation (TMS) to assess the corticodiaphragmatic pathway and diaphragmatic excitability, electrophysiological evaluation using P300 event-related potentials, and multimodal assessment of cognitive function, anxiety, and depression in COPD patients.

This thesis generated multiple peer-reviewed publications, including studies using magnetic resonance spectroscopy to examine cerebral metabolic alterations in COPD, demonstrating a measurable metabolic imbalance in the brain associated with chronic respiratory disease. Collectively, this body of work contributed to reframing COPD as a systemic disorder with significant neurophysiological involvement. Key elements of this work were presented at the CHEST Annual Meeting (Toronto, 2017), highlighting neurophysiological assessment in COPD, including P300 event-related potentials and cognitive dysfunction profiling.

Building on this foundation, Dr. Shaddad’s research expanded to encompass neurophysiological and cognitive dimensions across a broader spectrum of respiratory and systemic diseases, including post-COVID conditions, lung cancer, and inflammatory disorders such as Behçet’s disease and rheumatoid arthritis, with additional contributions in sleep-related respiratory disturbances.

He currently leads the Assiut University Interstitial Lung Disease (IPF) Research Program, a structured clinical research initiative focused on disease progression, acute exacerbations, and longitudinal outcome modeling in idiopathic pulmonary fibrosis.

His current research focuses on developing integrated clinical modeling approaches linking disease severity, biological phenotype, and inflammatory burden to improve patient stratification and disease monitoring in interstitial lung disease.

Dr. Shaddad has authored 17+ peer-reviewed publications and maintains an active citation profile. He is a high-volume peer reviewer, with over 50 verified reviews recorded in Web of Science and total reviewing activity exceeding 100 manuscripts across international journals (including 73 documented in ORCID).

He is an Editor of Monaldi Archives for Chest Disease and Tuberculosis and Respiratory Diseases (TRD).

In parallel with his research, he plays a central role in postgraduate medical education and academic governance, contributing to ethics committees, curriculum development, and the supervision of postgraduate research. He is a member of the European Respiratory Society (ERS) and the American Thoracic Society (ATS).

His current academic vision centers on advancing structured clinical modeling, neuro–respiratory integration, and standardized peer-review frameworks to improve the quality, reproducibility, and clinical relevance of biomedical research in respiratory medicine.
