Juli Valtschanoff, MD – Associate Dean of Evaluation; Professor & Chair of Medical Cell Biology; Chief Proctor

Dr Valtschanoff obtained his M.D. degree from Sofia Medical University in Bulgaria, where he practiced medicine, taught anatomy, histology and embryology to medical students, and did research on the involvement of the basal forebrain in Alzheimer’s disease. He went on to complete two postdoctoral periods in neuroscience at the University of North Carolina at Chapel Hill and remained at the same institution for 12 more years to run a successful research laboratory and teach anatomy to medical students and neurobiology to Ph.D. students. His research was on a variety of neurotransmitters and receptors in the somatosensory systems of the brain and the spinal cord with a focus on the mechanisms of pain perception. For the last 2.5 years at AUA, Dr Valtschanoff has taught anatomy and cell biology and has recently assumed the responsibilities of a Chief Proctor.

Associate Professor - Dr. John Th'ng John Th’ng, PhD – Associate Professor

Dr. John Th’ng has a Ph.D. in Biochemistry and Molecular Biology from the University of Western Ontario, London, Canada. His doctorate thesis was on DNA repair in mammalian cells. He did his post-doctoral training in the Department of Medical Biochemistry at the School of Medicine, University of California (Davis), California, USA. His research focus was on cell cycle regulation and chromosome structure in mammalian cells. Dr. Th’ng then became a Project Director and Assistant Professor at the Lady Davis Institute for Medical Research, McGill University (Montreal, Canada). He later moved to the Thunder Bay Regional Cancer Centre (Thunder Bay, Canada). His research as a Scientist was focused on the chromosomes and the cell cycle in cancer cells. Dr. Th’ng was also an Associate Professor and taught at the Northern Ontario School of Medicine (Thunder Bay, Canada). In addition to his academic experience, Dr. Th’ng had worked in the biotechnology industry. He established the DNA-based rapid detection of mold and bed bug contaminations in homes, produced agents for screening autoimmune diseases, and was a consultant to a forensic DNA company. Since June, 2013, Dr. Th’ng has been teaching Medical Cell Biology and Molecular Biology at the American University of Antigua School of Medicine.
