Welcome to my web site and feel free to contact me if there is something here that piques your interest. This is my 32nd year at Morehouse and I have had the good fortune to serve the institution in a number of capacities. I am currently the David Packard Professor in Science and teach a Cell Biology course and coordinate a Biological Research course in the Department of Biology. These courses are described in more detail in the Web Site. Teaching is my passion, and while as Dean of Science and Mathematics, no longer have to teach, will teach until I retire from the College.
I am no longer doing research, but I remain deeply interested in research on Hemoglobin S and sickle cell membranes, the topics on which I worked. I am also very interested in several other areas of cell biology namely the cytoskeleton and protein trafficking in cells. I have always attempted to integrate my research interests into the courses that I teach. From the very beginning of my career at Morehouse, I have served as both a faculty member and an administrator, which gives me a unique view of this institution from both sides of what many consider a significant divide. I have served as Director of the Office of Health Professions, Chair of the Department of Biology, and now as Dean of the Division of Science and Mathematics. All of these administrative experiences have deepened my commitment to assisting students in every way that I can towards maximizing their intellectual and personal development while students at the College.
Throughout my career at Morehouse, I have encouraged students to do research regardless of their career goal, because participation in research is a powerful way of developing problem solving and critical thinking skills, two of the most important goals of a liberal education. As Dean of the Division of Science and Mathematics, I have also encouraged students to seek a more interdisciplinary education, in recognition of the fact that the sciences are not separate in nature and the most interesting problems that we need to solve, such as renewable and clean energy, are inherently interdisciplinary. Finally, I continue to urge students to study and do research abroad, whether it be in South America, Africa or Europe. We live in a time where peoples from across the globe ore interacting in various ways, and we clearly need to be more knowledgeable about other cultures in order to gain the most from these interactions.

Biochemical characterization of sickle cell membranes
Regulation of cell volume
The symptoms of sickle cell anemia are due primarily to vaso-occusions, which result from red blood cell membrane damage. We have detected several alterations in the protein composition of sickle cell membranes, including the appearance of a unique high molecular weight protein. Continuing investigations aim at further characterization of these protein alterations and determining whether they play a role in vaso-occlusions.A wide variety of cells have been shown to maintain their volume in anisosmotic medium by regulating the activity of specific membrane transport systems. In marine fishes and in vertebrates, membrane transport of organic osmolytes, particularly amino acids, is principally responsible for the regulation of cell volume. In elasmobranchs, the key organic osmolytes are the (-amino acids, taurine and (-alanine. We have shown that skate erythrocytes regain their volume after swelling in hypotonic medium by releasing taurine through a gated-membrane channel, whose size appears to be about 6 Ao in diameter. We have also studied osmoregulation in shark rectal gland cell cultures. Inhibitor studies suggest that a different protein is involved in taurine transport in these cells and that a tyrosine phosphoprotein is involved. The goal of future work is to further characterize the regulation and mechanism of action of osmoregulatory transport proteins.
J.K. Haynes is the David Packard Professor in Science and Dean of the Division of Science and Mathematics at Morehouse College, in Atlanta, Georgia. He was born in Monroe, Louisiana and graduated from Morehouse College with a B.S. degree in Biology in 1964. He earned the Ph.D. in Biology from Brown University, in Providence, R.I. in 1970. After completing post-doctoral fellowships at Brown and the Massachusetts Institute of Technology, he was appointed assistant professor in the Division of Genetics and Molecular Medicine at Meharry Medical College in 1973.
In 1978, he returned to Morehouse as an associate professor of Biology and Director of the Office of Health Professions. In 1981, he was appointed a full professor of Biology and in 1985, chairman of the department of Biology and awarded the David Packard Endowed Chair in Science. He served as chair until 2001. He was appointed Dean of the Division of Science and Mathematics at the College in 1999. Between 1991-1996, Haynes served as a Visiting and Adjunct Professor of Physiology (Research) at Brown University.
He has directed a number of externally funded programs at the College whose purpose was to increase the number of students pursuing careers in research and medicine, and he has also been active in such efforts nationally. He served a six-year term as chair of the Minorities Affairs Committee of the American Society for Cell Biology (ASCB) and an additional three years as vice-chair of this Committee.
He has served on two National Academy of Science Committees, one on undergraduate science education and the other on programs for advanced study of Mathematics and Science in American high schools. He has also been a member of the Committee on Equal Opportunities in Science and Engineering (CEOSE), which advises the National Science Foundation, and two other NSF Advisory Committees: Biology Directorate (BioAC) and Government Performance and Results (GPA/AC).
From 2005-2008, he served as co-chair of the College Board Biology Commission which was charged with helping to develop a new AP Biology course. Between 2010-2012, he served as a faculty member at AAC&U’s Engaging Departments Institute, and served as a consultant for AAC&U’s Preparing Critical Faculty for the Future Project in 2012-2013. Haynes has been principle investigator on grants from the Howard Hughes Medical Institute, the Centers for Disease Control, the National Institutes of Health, the National Science Foundation, the Department of Education, the Department of Defense and the Department of Energy.
Dr. Haynes was a member of the Board of Directors of the Sickle Cell Foundation of Georgia from 1979 to 2008, a member of the Board of World Learning/School for International Training between 2004-2010, and a member of the Advisory Board for Project Kaleidoscope from 2010-2013. He is currently a member of the Advisory Board for the AAAS Vision and Change in Undergraduate Biology Education Initiative. He is a cell biologist who studied Sickle Cell Disease when he was actively involved in research.
Haynes’ biography is included in the book entitled, “Distinguished African American Scientists of the 20th Century (Kessler, et al Oryx Press, Phoenix, 1996), and an interview of him is included in the HistoryMakers Digital Oral Archive (2011).
