Dr. Karthik Suresh is a pulmonary and critical care physician. His clinical interests include acute lung injury and critical care medicine. He also specializes in the diagnosis and management of immune-related lung injury, especially in the context of autoimmune conditions and chemotherapy/immunotherapy for cancer.

Dr. Suresh is a member of the Hopkins immune-related adverse events (irAE) tox team. He also takes care of critically ill patients in the medical and oncology ICUs. He’s a firm faculty member for the Janeway Firm of the Osler Housestaff Medical Service and provides teaching to medical students, housestaff and fellows. more

Research & Publications


The Suresh Lab is interested in several basic science and translational projects. Its primary research focus is the study of microvascular endothelial cell (MVEC) dysfunction in various lung diseases including acute lung injury (ALI) and pulmonary arterial hypertension (PAH).

The lab is specifically interested in the role of mitochondria-derived reactive oxygen species (mtROS) and calcium signaling in promoting MVEC dysfunction in ALI and PAH; using animal models of these diseases as well as cells isolated from animal and humans. The lab studies the links between mtROS, calcium levels and mitochondrial structure/function with the goal of understanding the mechanisms driving mitochondrial and cellular dysfunction in lung MVECs.

Related to this project, in collaboration with the Izumchenko lab in Otolaryngology, the lab also employs computational approaches to discover somatic mutations in mitochondrial DNA with a goal of studying the effects of oxidant stress on induction of somatic mtDNA mutations in non-cancerous pathologies such as PAH.

Lastly, in collaboration with the D’Alessio Lab, the lab is conducting translational studies exploring mechanisms of lung injury in patients who develop pneumonitis after receiving immunotherapy.

Patient Ratings & Comments

The Patient Rating score is an average of all responses to physician related questions on the national CG-CAHPS Medical Practice patient experience survey through Press Ganey. Responses are measured on a scale of 1 to 5, with 5 being the best score. Comments are also gathered from our CG-CAHPS Medical Practice Survey through Press Ganey and displayed in their entirety. Patients are de-identified for confidentiality and patient privacy.
