Research Experience
2009-present Research assistant to Dr. John Chelonis in The Complex Brain Function Laboratory at
Arkansas Children’s Hospital in conjunction with the Food and Drug Administration,
assisting in behavioral research on learning, memory, and decision-making in children
with and without various psychopathological disorders
2012-2013 Sleep Deprivation and Frontal Lobe Lab: Duties include attending meetings regarding
upcoming research and experiments, implementation of studies examining the
relationship between frontal lobe function and mate choice among college students,
assisting in data collection, data entry, and presentation of findings under the leadership
of Dr. Jennifer Penner and Dr. Jennifer Peszka from Hendrix College.

Current Research Projects
“Depression and DMTS Performance Among Children Ages 7-14”
This research at the Complex Brain Function Laboratory compares the performance on the
Delayed Matching-to-Sample task (a measure of working memory) between children with or without the
presence of childhood depression. I have been assisting in the organization and analysis of the data
utilizing SAS, in literature searches for scientific articles relevant to our research, and I will be a co-
author on the manuscript.
“Working Memory Test Battery Protocol”
In collaboration with Dr. Chelonis at the Complex Brain Function Laboratory, this project
involves proposing a battery of various tasks which the scientific literature claims to measure working
memory performance. The project proposal is currently being reviewed by the IRB and, pending
approval, this test battery will ultimately be used to compare these tasks for convergent validity in order
to establish whether or not they are truly measuring the same psychological construct.
“Assessment of Working Memory: From the Animal Lab to the Clinic”
This research at the Complex Brain Function Laboratory examines whether the presence of a
childhood anxiety disorder affects the ability of children to perform tasks that have been used
successfully in animals to determine the effects of psychoactive agents on a variety of psychological
constructs. I am a research assistant on this project, which entails recruiting subjects, testing them on our
behavioral apparatus (the Operant Test Battery), scoring psychological assessment tests, and data
entry/management.
“Complex Brain Function in Children with Major Depression”
This research at the Complex Brain Function Laboratory examines whether the presence of
childhood depression affects the ability of children to perform tasks that have been used successfully in
animals to determine the effects of psychoactive agents on a variety of psychological constructs. I am a
research assistant on this project, which entails recruiting subjects, testing them on our behavioral
apparatus (the Operant Test Battery), scoring psychological assessment tests, and data
entry/management.
“Development and Validation of an Interspecies Cognitive Assessment”
This research at the Complex Brain Function Lab, under the direction of Dr. John Chelonis,
examines children’s performance on various operant tasks used to assess drug effects in animals
compared to their performance on neuropsychological tests used in clinical settings thought to measure
similar functions. I am responsible for recruiting subjects, testing them on the behavioral apparatus (the
Operant Test Battery), administering and scoring psychological assessments, and data
entry/management.
“Effects of Anxiety on Complex Brain Function in Children” (May 2012-Present)
This research at the Complex Brain Function Lab, under the direction of Dr. John Chelonis,
examines whether the presence of a childhood anxiety disorder affects the ability of children to perform
tasks that have been used successfully in animal research to determine the effects of psychoactive agents
on a variety of psychological constructs. I am responsible for recruiting subjects, testing them on the
behavioral apparatus (the Operant Test Battery), administering and scoring psychological assessments,
and data entry/management.
Projects Completed
“The Effects of Sleep Deprivation on Romantic Attraction during Speed-Dating Interactions”
This research at Hendrix College, under the direction of Dr. Jennifer Penner and Dr. Jennifer
Peszka, examined how inhibition of the frontal lobe (via sleep deprivation) affected mate preference. As
a student researcher, I assisted in recruitment of participants, executed a 31 hour sleep deprivation
procedure, transcribed videos of taped speed dating interviews between participants and experimental
confederates in both pre and post-sleep deprivation conditions, and I presented the results of the study
based on how inhibition of the frontal lobe affected the relationship of an interview’s communication
quality with romantic attraction, as well as the relationship between the physical attraction of the
confederate and romantic attraction.
Clinical Experience
2012-present Have gained much experience working with children suffering from major depressive
disorder and anxiety disorders (and thus ADHD, due to comorbidity) through assisting in research at
the Complex Brain Function Laboratory at Arkansas Children’s Hospital.
2008-2009 I had the opportunity to work with children with various psychological disorders (i.e. general
anxiety disorder and Aspeger's syndrome) in a class room setting at Vanguard Preparatory School in
Dallas, TX. I volunteered as a classroom aid for the teachers in a second grade classroom. My
responsibilities included assisting students with class assignments and assisting the pair of teachers
in charge of the classroom (i.e. making copies, assisting with problematic children, watching the
students during recess, etc.). I also volunteered to assist teachers with a summer camp in which
students were taken on field trips to experience the outdoors and help build social skills with other
children.
