Philosophy of Care

Providing the best care possible and treating each patient's case as if they were a family member.

Clinical Interests

Dr. Rashidi's clinical interests include: blood disorders (lymphomas, leukemias, myelodysplastic syndromes, myeloproliferative neoplasms, anemias, and coagulation/hemostasis).

He also has interest in developing artificial intelligence/machine learning tools for clinical, research and educational platforms.

Research/Academic Interests

Dr. Rashidi combines his passion for patient care and education with his unique training in bioinformatics and computer programming to create innovative new tools and resources that improve clinical practice and health. Dr. Rashidi is the co-founder, developer, and senior editor of HematologyOutlines, an online atlas used internationally by medical schools and other training programs, and endorsed by the American Society of Clinical Pathology for clinical laboratory scientist and medical technologist training. 

Dr. Rashidi also developed the educational app, HemeQuiz1, which includes quizzes in more than 15 categories, quick references, and a game center that allows users to compete with one another. HemeQuiz1 quickly became a top-selling medical app and available world-wide in 30 countries. 

In addition to the above, Dr. Rashidi has also recently published a print version of his renowned hematology atlas which has become a top selling atlas on Amazon.

Projects currently in progress by Dr. Rashidi and his team include development of artificial intelligence/machine learning (AI/ML) platforms applicable for diagnostic, educational and research use in multiple pathology subspecialty areas and other health science disciplines. Dr. Rashidi also is leading a project to improve clotting using poly-phosphates and silica nano-particles.
