Biology Research Laboratory is directed by Dr.
Josh Snodgrass and focuses on the development and
application of minimally invasive techniques (e.g.,
dried blood spots, saliva, and urine) for assessing
health and physiology in population-based research.
Our primary research in the lab involves the use of
biomarkers, such as cortisol, amylase and Epstein-Barr
virus antibodies, to better understand how psychosocial
stress contributes to the development and progression of
cardiovascular and metabolic diseases.
We also study human life history trade-offs in growth
and immune function using biomarkers such as C-reactive
protein and immunoglobulin E. In a project led by Klaree
Boose and Erica Squires, we are working with Frances
White and scientists at the Columbus Zoo to examine
associations between hormones such as oxytocin and
testosterone and behavior among captive bonobos.
The laboratory is located in the Center for Medical
Education and Research building on the campus of the
Heart Medical Center in Eugene, Oregon (1 block west of
UO). The lab is equipped to support immunoassay analysis
of human blood, saliva, and urine samples and,
additionally, provides facilities for data analysis.

Human Biology Research Lab
The laboratory also houses portable metabolic equipment,
including a MedGraphics VO2000 unit, which allows the
measurement of energy expenditure in lab or field
conditions. Additional equipment is available for
physical activity (e.g., Actical and Actigraph activity
monitors and Polar heart rate monitors), body
(e.g., bioelectrical impedance analysis instruments),
body temperature (Vitalsense telemetric physiological
monitoring systems), and cardiovascular/metabolic health
(e.g., blood pressure monitors, Cardiochek PA,
LDX & GDX, and Hemocue instruments).
