AAVSO Board Officers and Members - David Cowall








B.Sc., M.D. – The Ohio State University  

My professional career has been as a Medical Oncologist/Hematologist as well as a Hospice/Palliative Medicine Physician.  In my most recent capacity as the director of a translational medical research department, I oversaw clinical trials and observational research for a wide variety of illnesses.  I was actively involved in obtaining funding from grants, industry, and philanthropy.  My particular research interest has been end-of-life cancer care, and that has been the focus of several of my publications. I have also served for many years as a volunteer for non-profit organizations including The American Cancer Society and The Boy Scouts of America.  I retired on October 1, 2019.

I have been a member of the AAVSO since 1993 and have functioned as both a visual and CCD observer.  I have previously served on the Council Nominating Committee and have been an Instructor for two CHOICE courses.  I have published an AAVSOnet project on CY Aqr (JAAVSO Volume 43, 2015) and am currently writing a manuscript for publication on a possible period change of BW Vul using both AAVSOnet and Lowell Observatory data.
