Dr. Williams teaches several of the forensic biology track upper-level and graduate courses. She started her career in forensic molecular biology when she was appointed to a forensic biology fellowship with the Virginia Institute of Forensic Science and Medicine in 2002. Upon the successful completion of the fellowship, she worked as a forensic scientist for the Virginia Department of Forensic Science until 2007. As an examiner in Forensic Biology, she performed serological and STR DNA analyses on hundreds of cases. Dr. Williams has presented original research at conferences and in poster sessions, and has taught forensic biology related introduction and refresher courses for law enforcement personnel. She has testified as an expert witness in forensic biology in several circuit courts in the state of Virginia. She has publications in forensic science, molecular biology and biochemistry, has been a member of the Mid-Atlantic Association of Forensic Scientists since 2004, is a Fellow of the American Academy of Forensic Sciences, and is currently serving as a Commissioner for the Forensic Science Educational Program Accreditation Commission (FEPAC).
