He is an Honorary Member of the Indian Academy of Neurosciences (2005); recipient of the 2003 Distinguished Service Award, African Society of Toxicological Sciences; the 2002 Distinguished Scientist Award in Neurotoxicology, American Society of Toxicology; the 1998 Alzheimer's Association Brumback Award for Outstanding Achievement in Research; the 1997 Snider Foundation Award for Lifetime Contributions to Toxicology, and the 1997 Silvio O. Conte prize for basic and applied neuroscience contributions relevant to environmental health. Other honors include: Weil Awardee and Moore Awardee of the American Association of Neuropathologists; Member, American Neurological Association, and Fellow, Royal College of Pathologists (UK). National and international named visiting professorships and lectureships include: Alice B. Hamilton Lecturer, George H. Germann Memorial Lecturer, Sibte Hasan Zaidi Orator, Ellerman Lecturer, Hanninen Lecturer, Kugelberg Lecturer, Grass Traveling Neuroscience Lecturer, Sterling Visiting Professor, Sitlington Lecturer in Toxicology, and Tarbox Distinguished Neurosciences Lecturer.
