As an undergraduate, he conducted a population survey of western painted turtles (<em>Chrysemys picta bellii<\/em>) using mark-recapture techniques.\u00a0During undergraduate he also minored in Spanish. Following graduation, he interned at Omaha\u2019s Henry Doorly Zoo where he worked with many animals including tapirs, monkeys, lemurs, and pygmy hippos. \u00a0He also spent a summer working at the Butterfly &amp; Insect Pavilion where he interacted with emperor scorpions, giant centipedes, and bird-eating spiders.<\/p>\n<p>Johnny received a masters in Biology at Arkansas State University where his thesis focused on spermatogenesis, sperm morphometrics and the testicular cycle of the rough greensnake (<em>Opheodrys aestivus<\/em>).\u00a0 Along with his collaborators, he was able to deduce that rough greensnakes produce their sperm after mating and store it over winter to use the next spring, a process termed post-nuptial spermatogenesis.\u00a0 Sperm length was not significantly correlated with body size; however sperm tail length had a strong correlation with total sperm length.<\/p>\n<p>At UCF, Johnny plans to switch gears and focus on movement, habitat selection, and population genetics of the American alligator (<em>Alligator mississippiensis<\/em>).<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<div id='gallery-1' class='gallery galleryid-690 gallery-columns-3 gallery-size-thumbnail'><figure class='gallery-item'>\n\t\t\t<div class='gallery-icon landscape'>\n\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/sciences.ucf.edu\/biology\/hoffman\/wp-content\/uploads\/sites\/7\/2016\/08\/setting-up-siren-traps-150x150.jpg\" class=\"attachment-thumbnail size-thumbnail\" alt=\"A person in a green jacket and gloves is standing in a marshy area, surrounded by tall grass, with water around their boots.
