Dr. Elizabeth “Birdie” Shirtcliff
The early environment shapes children’s well-being and health; early adversity is well-known as a risk factor for wide-ranging problematic outcomes. Yet, the human sciences still do not understand how early adversity “gets under the skin.” Dr. Shirtcliff’s work focuses on biobehavioral mechanisms that illustrate the profound impact that a child’s early environment exerts on their physiology. Researchers in her SPIT Laboratory collect biomarkers noninvasively in humans. SPIT lab examine stress-biomarkers like cortisol, bonding-biomarkers like oxytocin, development-biomarkers like testosterone, or immune-biomarkers like herpes simplex virus. Ultimately, the goal is to use biomarkers to point to what really matters: the child’s family and social environment. Check out Dr. Shirtcliff’s video biography here.
Affiliate Assistant Professor of Research
Dr. Paula Ruttle
Paula is interested in how early life stress exposure influences the neurophysiology to increase susceptibility to mental and physical illness in adolescence. After completing her post-doctoral research fellowship at the University of Wisconsin-Madison, she took some time off to tend to family obligations, but her passion for research brought her back to academia as an affiliate assistant professor at ISU. She enjoys running, live music, and spending time with her husband and two children, Anderson and Noelle.

Lotte is from The Netherlands and enjoys Yoga, swimming, music and movies.
Dr. Wen Wang
Wen is interested in adolescent development, especially internalizing problems (i.e., depression, lack of empathy) linked with pubertal maturation and adolescent emotion regulation. Wen is experienced in hair assays and hair hormone studies, which is a novel methodology in psychoneuroendocrinology that works as a long-term indicator of hormone concentration. Her work includes validating EIA-based hair protocols for multiple hormones (cortisol, dihydroepiandrosterone, estradiol, testosterone and progesterone), cross-validating hair assays by comparing hormone concentrations in different bio-specimens, standardizing hair sample collection methodology and applying hair hormone levels. Wen is from China and likes Chinese-style cooking, swimming, and piano.

She carried out her doctoral work from All Indian Institute of Medical Sciences, New Delhi, where she studied a large cohort of patients affected with disorders of sex development and Polycystic Ovary Syndrome at clinical and molecular level. Her research goals are to study mechanism and role of sex and stress hormones. Iram likes traveling, discovering new cultures, reading history and watching movies.
Jenny Mai Phan
Jenny is a Predoctoral Fellow with the National Institute of Mental Health. Jenny studies puberty and its association with internalizing behaviors in adolescent boys, including autistic boys, with the aim to better understand buffering mechanisms attenuating biopsychosocial stress within parent-adolescent relationships. Jenny has studied a range of biobehavioral topics, particularly dyadic behaviors in mother-infant primates, adrenocortical and autonomic attunement in emerging adult couples, parent-adolescent agencies as predictors of rule compliance, HPA-HPG coupling during acute stress, and cortisol functioning across contexts. Jenny has conducted salivary and urinary enzyme immunoassays analyzing gonadal and adrenal neuroendocrine markers as well as immune markers and pituitary neuropeptides. Jenny is an active advocate for her sons who are diagnosed with Autism Spectrum Disorder and ADHD.
Olga’s research interests include adolescent sexual behavior, sexuality education, healthy family relationships, and pubertal development. Her Master’s thesis focused on the impact of childhood sexual abuse on diurnal cortisol and testosterone in incarcerated adolescents. Olga has worked on several SPIT lab projects, including the VerOFy Spit Study. VerOFy and LIAM comprise a near-real time salivary cortisol assessment technology. Olga coordinated beta-testing for this technology, and published on the topic of lateral flow assays. Olga is currently strategizing for her dissertation research, which will focus on training programs for educators and caregivers on how to provide comprehensive, developmentally-appropriate sexuality education to children and adolescents. Olga comes from Belgrade, Serbia. She enjoys snuggles with her cats Whiskey and Gnocchi, as well as cooking and the outdoors with her partner.
Shannin N. Moody
Shannin is a Presidential Fellow at Iowa State. Shannin is interested in neuroendocrine markers and their associations with pain. This includes physical pain (i.e., the cold pressor task, tolerance of extremely spicy foods), emotional pain (e.g. domestic violence, discrimination), and the combination of both through sexual masochism. Her research goal is to find an “objective” measurement of painful experiences. Shannin has led enzyme immunoassays (EIAs) of both small projects and multi-site studies. Shannin continues working on the lab bench as an assay technician and even learned how to conduct solid-phase extractions for urinary oxytocin and vasopressin. She is also versed in the extraction of steroidal hormones from hair. As a hobby, Shannin enjoys playing with fire(poi), biking, and paying homage to her past career as a bartender (cocktail concoctions).
Neil’s research interest is in studying human stress physiology, with a particular emphasis on the autonomic nervous system (known colloquially as the ‘fight or flight response’). From this lens, this emphasis affords him the opportunity to study a wide variety of subjects, such as virtual reality immersion, financial, and social stress. His main focus is on the way our physiology interfaces with our use of technology. Neil is a New Orleans native fond of reading and live music.
