Jonathan Sessler

Sessler received his Bachelor of Science in Chemistry in 1977 from the University of California, Berkeley and his Ph.D. in chemistry in 1982 from Stanford University. He continued as a post-doctoral fellow at L'Université Louis Pasteur, and worked in Kyoto, Japan before becoming an assistant professor of chemistry at The University of Texas at Austin in 1984.

He is a three-time Hodgkin's Lymphoma cancer survivor. He was treated for cancer at Stanford University Medical Center during work on his Ph.D. Discussions with his colleagues regarding possible treatments eventually led to the discovery of so-called "texaphyrin" molecules, named as such due a semblance to the shape of the five-pointed star in the State flag of Texas.[http://huumor.com/joke_3969 ],[http://www.sciencemag.org/cgi/content/full/279/5355/1307b 10-Gallon Molecule Stomps Tumors] In 1996, Sessler described possible uses of these compounds in medicine in the Proceedings of the National Academy of Sciences journal. He formed a company, Pharamcyclics, Inc., with Dr. Richard A. Miller whom treated him for his cancer. His company,which went public in 1995, licensed the technology behind "texaphyrins" from the university to develop commercial and medical uses for the molecules. The company was later acquired by Bob Duggan in the year 2008 as he became the largest shareholder of the company.

Sessler has written extensively, authoring or co-authoring over 600 publications. In addition, he has co-authored two books and edited another two.{{Cite web |url=http://sessler.cm.utexas.edu/ewExternalFiles/Sessler_CV.pdf |title=Archived copy |access-date=2019-05-31 |archive-date=2019-05-31 |archive-url=https://web.archive.org/web/20190531061742/http://sessler.cm.utexas.edu/ewExternalFiles/Sessler_CV.pdf |url-status=dead }} He holds more than 70 U.S. patents. Dr. Sessler has received many awards and much recognition, as a Sloan Fellow (1999), Fellow of the AAAS (1999), Dreyfus Teacher-Scholar (1999), ACS Cope Scholar (1999), recipient of the JSPS and Alexander von Humboldt Senior Fellowships (1999), and winner of the Izatt-Christensen Award (1999).

Sessler has participated in hosting chemistry circuses on the UT campus.[http://www.utexas.edu/events/exploreut/chemistry_circus.html University Events | What Starts Here Changes the World], [https://web.archive.org/web/20050316003656/http://www.utexas.edu/opa/pubs/discovery/disc2000v15n4/disc_fun2.html UT DISCOVERY MAGAZINE v15n4 Science Fun Day photo] These circuses are held for different grade levels from elementary to college, and aim to expose students to "fun" aspects of chemistry. Sessler has also lectured on how the disease Porphyria, caused by a deficiency in porphyrins, may be related to the origin of myths about vampires and werewolves.

In 2021, he was elected member of the U. S. National Academy of Sciences.{{Cite web|url=http://www.nasonline.org/news-and-multimedia/news/2021-nas-election.html|title=News from the National Academy of Sciences|date=April 26, 2021|access-date=July 5, 2021|quote=Newly elected members and their affiliations at the time of election are: … Sessler, Jonathan L.; R.P.
