Title: Associate Professor of Surgery

Research Focus: I am interested in examining clinical outcomes, expansion, applicability and value add to patients with Adult Congenital Heart Diseases and Aortic pathologies. My work is primarily centered around working with larger datasets by linking them to ask and answer important clinical questions. Collaborating is an important discipline and answering relevant patient centric questions is an important strategy for my work.

Current projects:

  • Clinical Outcomes Research in Adult Congenital Heart Disease and Aortic Diseases

Ruchi Thanawala, M.D., M.S.


Title: Assistant Professor of Surgery

Research Focus: I am interested in the role of informatics, AI, ontology science, and data science and surgical education, clinical practice and thoracic surgery, with the use and creation of large data to identify patterns. I have a unique skill set as a health informaticist, thoracic surgeon and the surgical education researcher. My research integrates these domains along with my experience in building out large data systems and platforms that are integrated with hospital systems such as electronic health records and national databases to create national level data sets for large-scale research.

Current projects:

  • Role of comprehensive medical education platform and the improvement in understanding of resident training and skill assessment
  • Oncology creation for relatedness of operation
  • Natural language processing to stratify skill level based on operative note dictations by trainees
  • Feasibility of telehealth as a primary modality of preoperative assessment in patients undergoing lung resection for lung cancer
