With a PhD in Biochemistry, I specialize in medical and scientific writing and communications with the past 7 years focused on medical writing for the biomedical and pharmaceutical industry (since 2012); I have over 16 years’ experience in the scientific field. 

I have been the principal writer for a variety of research topics and for studies across many  therapeutic areas. These projects have included: interviews with key opinion leaders; medical technology directory reports; Needs Assessments; CME course development (including grant applications, Q&A with data accumulation and slide sets); professional manuscript, abstract and grant writing (federal and private funding); medical and scientific conference coverage; clinical  overviews; and patient narratives. 

As a researcher, I have established and directed drug discovery collaborations with industry, collaborated with clinicians and researchers, directed a core facility, mentored graduate students, and trained laboratory technicians. I have also been a panel member for drug development, been an invited speaker at research hospitals and at national/international meetings, taught college- and graduate-level courses, and have been an invited journal reviewer as well as  primary author of scientifically reviewed manuscripts and textbook chapters for the medical community.

Therapeutic areas: Bone / Osteoporosis, Cardiovascular, CNS, Dermatology, Diabetes, Endocrinology, Hematology, Immunology, Inflammation, Metabolic Disease, Neurology, Oncology, Orthopedics, Respiratory, Rheumatology

Scientific research: Autoimmune Diseases, Biomarkers, Cardiovascular, CNS, Drug Discovery, Hematology, Immunology, Metabolism, Neurology, Nutrition, Oncology
