Teaching & Lecture Experience

1976-2006. Scientific invited lectures, presentations and colloquia. As a central part of my scientific career, I have given innumerable talks and lectures and presentations at conferences and universities around the world (see Scientific Abstracts below). I thus have had an enormous amount of experience in organizing complex material in a manner that is clear and communicative and interesting, and most importantly, understandable by diverse audiences with different backgrounds and levels of expertise.

1980-1981 Graduate Seminar in Systems Neuroscience, Departments of Psychology and Electrical Engineering. This was a high-level seminar course co-taught by me and Dr. Robert Pinter from the College of Engineering. Students were guided through reading of and evaluation of significant new scientific papers in the field of visual neuroscience.

Summer, 1984. Introduction to Bioengineering. College preparatory summer course for advanced placement minority high school students at the School of Optometry, University of California, Berkeley. I taught these bright HS students the basics in the anatomy, physiology and perceptual psychology of hearing, vision and the cutaneous senses, with the major emphasis on vision. Towards the end of the unit on visual perception and the physiological basis of some well-known perceptual illusions, we did a field trip to local art museums.

1986-1995. Monthly lectures to parents groups at Kaiser Hospital and California Pacific Medical Center, SF, CA, educating parents about normal and abnormal visual development of infants.

Fall, 1994. Guest lecture in the sophomore science class (Frank Daar, teacher) at Arrowsmith Academy, Berkeley, CA. Taught a class on the human senses, focusing on vision and visual perception.

2004-2006. Preceptor to a Postdoctoral Fellow, Ali Navid. As Dr. Navid's preceptor, my main role was to teach and train him to help promote his success in a scientific research career. I spent many hours teaching him about our field, about visual neuroscience, and about writing up scientific results and research grant proposals.

July, 2007. Postgraduate level class in visual physiology and photoreceptor function, phototransduction. By invitation of Professor Luiz Carlos L. Silveira, distinguished professor at the Centro de Ciências Biológicas, Departamento de Fisiologia at the Universidade Federal do Pará in Belem.

2007-present. Professor Visitante, Laboratorio de Psicologia Experimental, Instituto de Psicologia, Universidade de Sao Paulo, Sau Paulo, Brasil. In early 2007 I had the honor of being invited to become a Visiting Professor at the prestigious University of Sao Paulo in the Psychology Department. My first semester, I taught visual physiology and perception to graduate students in the Psychology Department with an emphasis on three important topics: (1) physiology and phototransduction in vertebrate photoreceptors, which was my most recent focus in my research career; (2) visual development in human infants; (3) the course concluded with an open seminar on "Ethic & Animal Research" which I designed and guided. By invitation of Dra. Dora F.Ventura, distinguished scientist and head of the Laboratorio da Visao at the Insituto de Psicologia.

2007-present. Co-orientador, Laboratorio de Psicologia Experimental, Instituto de Psicologia, Universidade de Sao Paulo, Sau Paulo, Brasil. I am a co-orientador, with Professor Marcelo F. Costa, for a mestrado student, Fabio Carvalho, in Dora Ventura's lab.
