Biology Research Laboratory
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 and saliva) for assessing health and
physiology in population-based research. Our primary
research in the lab involves the use of biomarkers, such
as cortisol, alpha-amylase and Epstein-Barr virus
antibodies, to better understand how psychosocial stress
contributes to the development and progression of
cardiovascular disease. We also study life history
trade-offs in growth and immune function using
biomarkers such as C-reactive protein and immunoglobulin
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.
to the 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).
My lab is located in the same lab cluster as other
several other UO labs and shares resources with a number
of human physiology labs, including the Andrew
Physiology Lab, Hans Dreyer's Muscle Physiology
Lab, and Jeff Gilbert's Renal and
Reproductive Physiology Lab; Kirstin Sterner and
Nelson Ting's Molecular
Anthropology Lab; and Pranjal Mehta's Social

measured from dried blood spot samples.
