College of Physicians & Surgeons ABIM 1994 Internal Medicine Univ of Med. & Dentistry of New Jersey ABIM 1997 Haematology/Oncology Haggai Institute Cert. 2006 Advanced Leadership A. Personal Statement I have, over the past 10 years, through institutional collaborations mentored both undergraduate and clinical Postgraduate trainees from University of Michigan, University of Utah, The University of Hamburg, among others in Internal Medicine, Haematology /Oncology . I established and led work at our Viral Hepatitis Deferred Donor Clinic for the past 15 years My main interests have been in the clinical areas of Chronic Hepatitis B infections, Nucleic Acid Testing in Pre-Donation Screening Transfusion Medicine, and using platelet flow cytometry as a marker for platelet activation. My clinical work involves the treatment of a wide range of malignacies and haematological disorders. However, I have a keen and still growing, interest in medical education and lately Open Educational Resource (OER) in the health sciences that has culminated in my appointment as the Coordinator for OER activities in the College of Health Sciences. This has involved the drafting of a university wide policy, designing and operating an OER production/publishing system. I have mentored students at all levels, recently serving as a mentor for students in the Minority Health International Research Training Program. I am pleased to colloborate in this HBV study B.

Research Summary

(inferred from publications by AI)

The researcher's focus is centered around three main themes: stroke rehabilitation, folic acid research, and nutritional deficiencies in Ghana. These themes encompass broader public health strategies (stroke rehabilitation) and specific dietary challenges (folate and B Vitamins). The other areas, such as infectious diseases, medical education, and public health impacts from climate change, appear to be underrepresented compared to the more prevalent topics within these themes.
