WebIn hyperphenylalaninemia, an enzyme called phenylalanine hydroxylase (PAH) is not made correctly. This enzyme helps change phenylalanine into other amino acids that your body needs. When PAH is missing or severely damaged, phenylalanine cannot be processed. This more severe version of hyperphenylalaninemia is called classic phenylketonuria or PKU. WebKian joined the lab during his freshman year at OSU. He was a Johnson intern and contributed to the phenylalanine monitor project developing methods of dry reagent preservation. Kian was then awarded a CWI internship and worked on the development of arsenic sensing. He continued the arsenic sensor work for his Honors College thesis.
