Hugh Rosen lives in San Diego, California, which is 400 miles from his favourite Eastern Sierra trout streams. He began fly fishing in the early 1980s while a university student in his native South Africa. He retains a life-long affection for the Kloof streams of the Cape, and for dry flies of his youth, especially the RAB. He learnt to tie flies from that great exponent of Catskill tying, Matt Grobert in Summit, NJ, and has tied flies with harmless obsessive intensity ever since.
Hugh enjoys the camaraderie of fly tying and sharing photographs with the community by troubling billions of electrons on social media. He combines a love of trout stream biology with his day job as a medical scientist and Professor at The Scripps Research Institute and has travelled for science and fishing to England, Wales, Austria, Slovenia, North America and Australia. He has a well established reputation as a world class shrubber, and were he to fish a stream devoid of any shrubbery except the smallest bonsai, he would lose almost every fly in his possession to that miniscule sapling. Together with his colleagues, he discovered a treatment for autoimmune diseases most notably multiple sclerosis, for therapeutics is just a variation on fly fishing.
