Dr. Joel S. Brown is a Senior Member of Integrated Mathematical Oncology at the Moffitt Cancer Center, and Distinguished Professor of Biology Emeritus at the University of Illinois at Chicago.  He is a wildlife biologist, urban ecologist, and cancer researcher.  Childhood experiences in Zimbabwe created a love of nature and animals that grew into an academic career. For 30 years, his laboratory and graduate students have worked from A to Z, from aardvarks to zebra, with a particular love for squirrels.  He takes an evolutionary approach to wildlife behaviors, populations, communities, conservation, and most recently cancer.  Dr. Brown applies ecological and evolutionary principles to define, study, mathematically model, and treat cancer.  With Drs. Zhang and Gatenby, Dr. Brown developed the first mathematical model of adaptive therapy that was applied to a successful clinical trial of castrate resistant metastatic prostate cancer.  Joel completed his bachelor’s degree in zoology at Pomona College (1980, Prof. William Wirtz, advisor), and his Ph.D. degree in ecology and evolutionary biology at the University of Arizona (1986, Profs. Michael Rosenzweig and Thomas L. Vincent, advisors).
