Professional Interests

Dr. Suadicani is an expert in the area of intracellular and intercellular signaling with a strong background in Cellular Biology, Physiology and Pharmacology. Her research currently focuses on the investigation of mechanisms contributing to development of benign bladder dysfunction, particularly the involvement of pannexin 1 (Panx1) channels and purinergic signaling in the development of diabetic cystopathy, interstitial cystitis, neurogenic bladder in Multiple Sclerosis and spinal cord injury, and in mechanisms leading to development of Urologic Chronic Pelvic Pain. 

Dr. Suadicani’s general interest and expertise in the pathophysiology of cell signaling have also led to collaborations with faculty from other departments at Einstein and abroad.  Examples of ongoing collaborations are studies conducted with Dr. Kelvin P. Davies (Department of Urology, Einstein) to better understand mechanisms that underlie development of benign urologic conditions, studies with Dr. David C. Spray (Department of Neuroscience, Einstein) focused on pelvic pain, studies  with Dr. Mia M. Thi (Department of Orthopaedic Surgery, Einstein) to investigate the effects of diabetes on bone cell mechanosensing and transduction, and studies with Drs. David J. Sharp (Department of Physiology & Biophysics, Einstein) and Kelvin Davies to identify new targets to treat acute spinal cord injury and associated bladder and erectile dysfunction.
