Her undergraduate honors thesis entailed the development and evaluation of a highly sensitive liquid derivatization technique for the measurement of gas-phase nitrous acid (HONO). She also had the opportunity as an undergrad to develop, test and apply a chemical actinometer for the measurement of the HONO photodissociation constant. Kristin Julianne completed her Ph.D. in Atmospheric/Physical Chemistry at the Centre for Atmospheric Chemistry in Professor Geoffrey W. Harris’ research group, also at York University. Her doctoral research, a kinetic study, investigated the photoenhanced reduction of nitrogen dioxide on organic films (mainly humic acid) as a missing source of daytime tropospheric HONO. Kristin Julianne received several awards at York University for her studies in HONO chemistry, including: Harold I. Schiff Award in Atmospheric Chemistry; Charles Hantho Award in Atmospheric Chemistry; Junior Fellowship Program Undergraduate Research Awards; and an Ontario Graduate Scholarship at the doctoral level. Currently, her research activities involve indoor and outdoor chemistry of nitrogen dioxide to form HONO as well as other aspects of photochemistry in the indoor and outdoor environment.

  Alaa joined the Grassian Group in 2012. She worked as a lecturer in Alkut University in Iraq after receiving her master degree. Alaa’s research focuses on investigating the chemistry of nanomaterials in the aqueous environments using different analytical techniques such as dynamic light scattering, HPLC, ATR-FTIR spectroscopy with an the emphasis on the role of surface chemistry. Nanomaterials behave differently than larger particles. It is therefore necessary to develop specialized methods to testing and monitoring the environmental and health aspects of the nanomaterials.
