  • Liv is a Ph.D. candidate in the Department of Chemistry at UCLA. Liv studied as an undergraduate at the University of Wisconsin- Milwaukee and graduated in 2015 with a B.S. in Chemistry and Mathematics. A Milwaukee native, her research interests in math began as a student in the BioMath program (https://www4.uwm.edu/ubm/ ) under the mentorship of Dr. Gabriella Pinter. To study the population dynamics of invasive bivalve species and the influence on nutrient cycling in Lake Michigan, stochastic modeling was employed to understand underlying processes given data collected from the lake. She also worked under Professor Joseph Aldstadt to develop an analytical chemistry method to study the kinetics of the Maillard Reaction. Separation and measurement of reaction mixtures over time were investigated to test the effects of conditions such as reactant concentration, pH, and ionic strength on the stages of sugar and amino acid crosslinking processes. As a Ph.D. student working under Prof. Anne M. Andrews and Prof. Paul S. Weiss, Liv is developing aptamer-based field-effect transistors incorporated into microfluidic flow systems, with a goal of creating reversible sensors to better understand neuromodulation pathways integral to behavior. Liv enjoys spending time painting.

Katie Perrotta

  • kperrotta@g.ucla.edu
  •  
  • Katie is a Ph.D. candidate in the Department of Chemistry at UCLA. Katie graduated with a B.S. in both chemistry and neuroscience from Muhlenberg College, a small, private, liberal arts college in Allentown, PA. Her primary undergraduate research was performed under the co-mentorship of Drs. Christine Ingersoll and Jeremy Teissere. The collaborative project involved the chemical and pharmacological analysis of Passiflora incarnta in order to wholly understand its anxiolytic properties. Katie designed HPLC and ESI Spectrometry methods to characterize the flavonoid constituents in a commercially available passionflower extract. Flavonoids have been experimentally shown to act on the GABAA receptor, making them a prime candidate as the active chemical component of passionflower. In the lab of Anne Andrews, Katie will be using fast scanning cyclic voltammetry and microdialysis to monitor serotonin in vivo. She is also investigating the effects of maternal stress on long-term behavioral and neurochemical outcomes in offspring.
