For example, I examined the daily (Le, Fredman, McDaniel, Laurenceau, & Feinberg, in press) and longitudinal (Le, McDaniel, Leavitt, & Feinberg, 2016) associations between coparenting and couple relationship quality within the first three years after the birth of the child. I also examined the mediating role of parenting stress at one year postpartum in explaining the prospective association between parental negative affectivity at 6 months postpartum and harsh parenting at three years postpartum (Le, Fredman, & Feinberg, 2017). Right now, I'm working on my dissertation examining couples' daily adaptive and maladaptive relationship processes.

I have also sought to extend my work studying couple processes on short time scales beyond the early parenting years to examine how couples regulate emotion on moment-by-moment, micro time scales. For example, I am taking the lead on a collaborative effort between Penn State and New York University to elucidate the temporal dynamics of couples' anger emotion during conflict discussions by applying dynamical systems modeling. I am also involved in an NIH-funded project led by Dr. Steffany Fredman in collaboration with a team of Penn State methodologists to characterize how couples with posttraumatic stress disorder regulate and co-regulate emotional arousal on a moment-by-moment basis by mining and analyzing emotional arousal encoded in the voice.
