Dr. Clyde Goulden, a pioneering ecologist and director of the Asia Center of the Academy of Natural Sciences of Drexel University, has devoted his life to studying climate change and how it is affecting Mongolian herders and the pristine 2-million-year-old Lake Hövsgöl. His efforts have now been recognized with Mongolia’s highest award to foreigners, the Order of the Polar Star. In a separate honor, Dr. Jon Gelhaus, Academy curator of entomology and professor in Drexel University’s College of Arts and Sciences, has received the Kublai Khan medal for his scientific achievements in Mongolia.
