Current
Research
My research interests involve development of bioimpedance and biological sensing modalities in radiation biology.
I would like to learn to best employ bioelectric modalities as a way of learning about damage information in living systems. I'd also like to
find out how physical connections between cells and their environment are important in the movement of this information.
My supervisors and funding have directed me into two different areas:
+ Study of DNA damage sensor threshold in mouse embryonic fibroblasts - Here, we are examining genetic effects on
radiation sensitivity of a classically observed G2M arrest in response to radiation. This work is conducted under the auspices of the DOE's
Low Dose Research Program. The main goals of the work are to examine genetic contributions toward
checkpoint function in the context of lower doses to radiation. In the course of these studies we will establish the threshold of distinction
and the threshold of detection for this biological sensing mechanism.
+ Bioelectric dosimetry modalities. Our current work involves the investigation of the electrically measurable responses to
radiation exposure and the assessment of those modalities for high throughput dosimetry. Funding here is provided via a
CMCR award.
Like many others, I end up building a fair number of the things I need to get the answers I need. My
portfolio of
engineering projects is available for perusal on request. One example is a time lapse video microscopy system I made from spare parts
around the lab that generated the movie shown here below:
